Special offer for 2 x Continental GP4000s II folding road tyres with 2 free inner tubes

The ultimate road race bike tyre, that transforms the performance of any race machine!

The Continental Grand Prix 4000 S road tyre has been developed and refined over the years, and is known around the world as one of the best race tyres on the market. Race proven, and road race tyre of choice for professional road cycling teams BMC Racing Team, Orica Green Edge, Lampre Merida and Lotto Belisol.

Continental have taken their legendary GP4000s road tyre and given it a facelift. Now offering a subtle coloured sidewall to match to the colour scheme of your bike. They have also added a new size to the range, GP4000s II is now available in 28mm. This provides better grip in greasy weather conditions, increased puncture protection and better all round comfort. The new tyre also features the latest version of the Continental's BlackChili compound. Which now offers even lower rolling resistance, greater milage and increased grip in wet weather conditions.

The backbone of the Grand Prix 4000 s road tyres remain unchanged. The 4000 S II still has the same Vectran Breaker for great puncture protection, BlackChilli compound for unsurpassed grip performance and low rolling resistance, and not forgetting hand built in Germany.


  • The global leader in the premium race bike tyre market.
  • Strong in every department - a real all round race bike tyre.
  • Advanced Black Chili compound for an even faster, safer ride.
  • Vectran Breaker technology for increased puncture resistance.
  • Colour Black
  • Size choice of 23, 25 or 28mm
  • Transforms the handling of any race machine.
  • Offer includes: 2 x GP4000S II Road Tyres and 2 x Inner Tubes 
Inner tube sizes are given in their desciption, e.g. Standard Presta Valve Inner Tube Road - 700c - 700c / Presta / 19mm / 25mm / 40mm Valve. The 19mm and 25mm are the minimum and maximum tyre widths, accordingly this inner tube would be suitable for tyres between these sizes, but wouldn't be suitable for a 28mm tyre for example. The 40mm refers to the valve length.
Paul GP4000's are always a reliable tyre with great rolling resistance, grip and puncture protection. However, with the introduction of the GP5000's these tyres are becoming harder to source. Thanks to Merlin, this bundle is a life saver and a bargain with the inclusion of two free inner tubes. Add reliable and fast delivery, this bundle is a no brainer for the price.
SamC Great product, prompt delivery, good price - Fast & grippy tyres for dry days and racing
Drongo67 Great clincher tyre. Wears well, few punctures, good speed,. Need levers to remove, but rolls on rim without needing levers, as they should. Have bought these few times previously, great wear, OK in wet. Great price when on special at merlin.
Russell Long time user of the GP4000Sii. Always been a good reliable tyre, very rarely have any punctures or problems. Been very reliable.
Mr Newstead Arrived quickly as normal with Merlin cycles. Tyres went on fairly easy for a first fit. Been on a couple of rides they feel softer than my old tyres and give nice ride. Rode on dry and wet roads grip excellent in both conditions.
Mr Neethling Excellent racing and training tyre. No issues experienced previously that's the reason for continued use of the product. Overall great value item.
Rusty Love these Continental tyres, good ride in most weather.. will get 4000 miles out of them.
Miss Gatti Oliari Ótimos pneus, segundo par que utilizo, pouquíssimos furos e boa durabilidade. Não uso outros pneus senão os GP.
David Good price and with free tubes Merlin spot on for these popular tyres. Have been using these for a number of years and find they offer great performance and grip
Mr Paton Great tyres, smooth roll and minimal punctures .
Mr forteza Best tyres for roadbike until the gp5000 came. lol. Seriously, at 1000km the performance is still premium & prestine.
Mr Hesketh High quality road tyre. Rolls well, good puncture resistance, average longevity.
Smash Bros Cycling Great tires! So far I've put 500 miles on them with no issues.
Mr Mc Donald Great tires really good in wet weather. I’m running the tires at 6 bar pressure and the ride and comfort is excellent I would recommend them. Now I need to get a set of conti 5000’s .
MJG Brilliant tyres! They are easy to fit by hand. I use them all year round as I can rely on them to grip in any conditions and get me home without mishap. Don't feel the need to try or pay more for anything different!
Robert Great tyres with excellent grip & good puncture resistance
Mr Deslandres Amazing upgrade over the tyres that came with my stock wheels. More comfortable ride, faster acceleration, and better cornering.
mack My favourite tyres, I am sure the GP5000 is technically better, but I cannot tell the difference. These are much cheaper, so will continue buying these for as long as they are available.
B Great tyres but for some reason this time a nightmare to get on with the free tube
Marc Duperron One of the best all around tyres
Mr Ridley great tires, big for a 25 mm more like a 26.5 mm tire
Miss Katona Super!
Bikey Bloke Great Tyres. Been using them for years. Great rolling resistance and puncture resistance.
Jim McG Very happy with these tyres. Have been using them for years. I will have to get a new go to Summer tyre when stocks of these run out
steven I've been using these tyres for some time now and I think they are the best clinchers around. Easy purchase at a good price.
Mr Cassidy Great tyre, great Merlin offer. Long may they continue.
Robert Great tires very smooth ride, they corner very well!
Herbert 2018 best tyres still the "best" even when compared to the new 5000 especially at a great price. Arrived on time, they are just sitting in a drawer as spares, love them, can never have too many spares!
Mr Tooth Used these tyres for many years now with no punctures! Why change? Superb
Mr. Shafly Great tires are even better when they're available at a deep discount. I've really enjoyed these tires. The 28s feel fast and help smooth out the rough roads in my part of Canada. Two thumbs up! 👍👍
Becky I was recommended these by a friend after getting a puncture which made a mess of my old tyre. Far easier to put on than the beaded, wire ones I had, so should be faster to change inner tube during events, if get another puncture. I'm yet to actually go out for a ride with them on the bike, so can't comment on how well they work yet...
The Pitman Good deal and very quick delivery.I trust these tyres 100% rain,hail,snow,or shine.Also get good mileage out of them,hence buying 2 more and another summer sorted,do we have summers in UK anymore ;)
FS My favorite tires to puncture resistance and handling. I use no others!
C Steele The GP4000s are a great tyre. I had last set for 4 years and just immediately got these again. Great choice.
Mr Meyer Good ride, heavy duty tire. Great for training.
Dave Great tyres, on my 3rd pair. Last for ages and fairly picture resistant and very grippy.
Mr Nielsen Can't beat these tires for the price! I may be fortunate but these last and last and last with virtually no issues.
Mr mcindoe Best tyres ever, I have 2 road bikes with GP4000`s over 7000k on one and 6000k on the other no flats
Sarah Fitted these pretty easily. So far only ridden once but a noticeable improvement. Very light and achieved some PRs. Happy so far. Quick delivery too.
ROGER V. Continental GP4000s II is really reliable for long rides, smooth and nice grip on the road. Puncture resistant based on my experience and usage.
Matthew The Grand Prix is an amazing tire, as usual. I have used them for years and they are always my tire of choice. Merlin’s price, especially the deal with tubes included, is the best you can find online. Highly recommend.
Ronald Allan Really nice. Very durable tires. Fast rolling & hugs the road very well! Highly recommended!
Mr Diamond Excellent tyres, replacing the same which are worn, big ride coming up.
John Probably the most popular tire around, long lasting with good grip, great price and fast delivery from Merlin
Seyed Hampshire I recently bought a pair to replace my existing ones that the previous owner installed. Very good hard wearing product. Lasted well and no problem with punctures. Good rolling speed and safe traction. The reason I changed was I picked up a nick from a glass or something and being at 8.5 bar I did not want to risk riding on it . The Kevlar inside kept intact . Recommend it .
Mr Wood Lightweight, sticky and durable tires. Merlin always has the best tire prices.
David Very pleased with these tires and tubes. Ride is smooth and fast. Wouldn't hesitate to buy them again.
Alan Great tyres, tried a few different tyres but always come back to these. Went for the larger 28mm this time and they help a bit with the rubbish road surfaces in my area.
Mr Ruta Great tires. Good grip and wear well. As my old tires have worn out or cracked, or I have switched to 700x25s I have put these tires on all 5 of my bikes. Can feel the difference at once.
Mr Velez Excellent tires. I be use this tires for 4 years and ride about 15k km with no problem. I recommend this product.
Ian We don't need twice the price for the new 5000s, we want conti to keep making these.
Mr Hahn I switched from a Bontrager tyre to these and find that there is a notable difference in the comfort, the GP4000s being the comfy one. The difference is fairly small but noticeable especially on a 100+ ride
Mr Periquet Been using these tires for a long time. Best all around tire in my opinion and the price is right...
Mr wu Durability and road grip of these are well known, I get a set of these each season which usually lasts 4,000+ miles.
Eric Great tyres. Used for years. Never a problem
Christopher Great tires at a great price! With latex tubes, a great deal. Eventually, I will move to the GP5000, but can't resist these excellent tires.
Alain So far, these are the best road tires I used. They are very comfortable and sticky on the road. A must have!
Mr Bowen Great value. I've bought these tires from Merlin many times and have always been satisfied.
Stephen Grippy go tp tyres. Have been using these tyres for all year round reliability. If you don't need/want tubeless then these are well priced now.
Mr Larson Best tires you can buy at a fair price. Extremely impressed at the fast shipping to the USA. You guys rock.
Mr Kim Fantastic tyres. They feel very nice on the road, especially the 25mm versions.
vinil The best tyre for the road biike, good grip and puncture resistant
Tauno_Tunkkari Rolling very well. Best tires for the first road bike. Best price found for couple of tires. Note, Continental inner tubes were available only as 60mm valve.
Mr Nielsen Love them, I've used these tires for years and have excellent life from them. Highly recommended!
Mr Lin My first time to use 28mm GP4000SII. More comfortable!
Mr Faustino Fast, grippy and high-quality tires. Can't comment about puncture protection yet.
Grant Best price I have found on great tires. They hold up season after season.
ian Very good road tyre can be used for training and racing. I like the great service that Merlin Cycles are renowned for. I`m impressed with the allround qualities of this tyre
Mr Covington Great price and on top of that some Inner tubes. This is the best tire I have ever used. I have gotten very few flats since using these.
David Love GP 4000s. High quality, fast and smooth
Mr Chow Great all around tires, decent puncture resistance, low rolling resistance, comfortable and lasts pretty long
Mr Williams GP4000s are the "go-to" tyre for serious and casual (me) cyclists. I've used them for years and watch in wonderment as others get puncture after puncture and don`t swap to GP4000 plus I out-roll nearly everybody I ride with
Larry Switched to these tyres last year. Longer lasting and roll better than the Vittoria tyres I was using
Matt Trying these out for the first time following recommendations, on the first few rides grip appears good normal top quality expected from Continental
Gary Superb tyres, fast, reliable and look good
Mr Coleman Great tyres offering perfect balance of durability and rolling resistance. At this price, unbeatable !
Gino Great deal - awesome tyres, great grip and durable. The only clincher tyre I have used in the past 4 years
Norman Great tyres. Amazing cut and puncture resistance as well as fantastic grip in wet and they wear slowly
Mr rosen Contis are the best out there. Highly recommended for combination of handling, endurance, and wear-life.
Mike V. Long time user of Conti GP 4K's, and I can tell you it's a great tire. Puncture resistant, low rolling resistance, and quality that you just can't beat. Even a better tire now that the introduction of the 5000 has lowered the price.
Thomas Ng Smooth rolling and reliable tyres.
Ahmad Installed on my cannondale 105 SE with WTB 30's and the difference was immediately noticeable. They didn't just feel fast they were faster by 2kmph on average according to my strava tracker.
Mr McGrade So far these tyres have performed well. Had them for about 700kms and were an easy install and appear to be wearing well. Better than my old gator skins
Edmond I`ve had these for a few weeks and they live up to their reputation . Great feel on the road with excellent grip in the corners
Michael Excellent road tyre 700x25mm, use on all my bikes, good grip in wet and dry conditions, good mileage and puncture resistance.
Mr Smith Simply brilliant particularly in the 28c width, so much more comfortable and just as much go as the narrower options on this tyre. Nothing negative as these are my go to tyre every time and Merlin are simply brilliant from a price and customer service perspective.
Kent The Conti GP4000S II is really a nice tire, very smooth road feel, long life.
Manson Always a favourite of mine. They roll really well and last for about 4000km for me.
Clifford Bought these just before the GP 5000 was released. Good price, no evidence of cuts after riding on rough Chiltern roads. Easy to fit, give confidence when riding.
Derek I've used these tyres several times before and can't see any reason to change, they roll well give good grip in wet and dry conditions and a puncture is a rare event.
Kiwi racer Very good as always. Not prepared to buy the 5000's yet as too expensive and about 1% improvement over the gp4000's. 4000's also tested as being more puncture resistant.
WilierKing Used on many rides and always grippy, reasonably fast, and durable. Good value.
Mr Leman Best folding tyre, reliable and not easy to get puncture. Plus the 25 mm is just perfect. Good price by Merlin
Allyn Not much to add about these tyres. I've used them for years and find them to be the best all round summer tyre. They may have been superseded by new GP 5000 but they are still excellent and this is a very good price. Also excellent service from Merlin.
Mr gilmore Leading tire for rolling resistance and grip - perfect
Mark Exceptional value for an exceptional pair of tyres. Great grip and rolling speed with the advantage of puncture protection. My favourite all round tyre.
Mr Coady These tires are excellent, I have a pair on my bike right now, and bought another set to keep on hand for when I wear them out. I've had no issues with pinch flats or punctures with these tires, and I find them more comfortable and faster than the ones I was using previously. I've had the 23c and and 25c I think the 25c is a tiny bit better cornering and a little more comfortable. Both are great products
Mr Drummond Brilliant tyres - never believed in anything about rolling resistance on tyres until I tried. Compared to my last CST resource tyres, this felt very comfortable and rolling pretty well. Merlin has the best price anywhere in the shop, online or physical shops then they added 2 free inner tubes - which was more generous and plus member discount and reward points deduction - overall £54.99 price is one of the best bargains out there. Note: only used it for commuting in Autumn and this early winter - grip is sensational.
Steven K. These are the first 28mm tyres I've ever bought. I wasn't sure whether of not they would clear my brake pads, but they do, although a tight sqeeze. Having a lower tyre pressure is great, smoother ride (we've got some fairly rough roads in our area) so the lower pressure was a big help. A real treat to ride on. Merlin shipped them out the same day I ordered them (not sure why they came from Spain though). Great tyres, super service and price. Would have been nice to have been able to get inner tubes that worked with the 28mm tyres, but still, nothing in life is perfect.
Mr Freire Best tyres in the world, I used them on the road for almost 10000km and they`re ok
Mark Arrived in Spain promptly and without fuss directly to our door. Great tyres and tubes, run really well and puncture free my last purchase for over 5,000km
Carl I am now and always have been very happy with my Continental GP4000s II Folding Tires. I have been using them for years and they have never let me down. This time Merlin included free tubes with the tires at a great price!
Enrique Awesome tires. I have been using them for a while and I absolutely love them. Light, fast, comfortable and resist punctures really well. Highly recommended. As always, great and fast service from Merlin as well.
Mr Moran Excellent tires and tubes at the best price. I prefer Continental tires and tubes because the ride quality and durability is great. Thank you.
Michael Classic fast rolling reliable tyres at a great price
Mrs Wade Just amazing. Really good price and went on with no difficulty. Free innertubes are a bonus.
Ryan M Easy to mount, smooth rolling, and durable.
Dennis The GP 4000s2 tires are the only tires that I will use. I have used them for many years and they never let me down.
Poom These tyres at 25mm seem to be the perfect balance of speed and durability. I have used them in multiple long distance (> 600 km) events and got almost zero flat. I have used 23mm before and I found 25mm to be much better in all aspects.
HasNoCar Everyone knows these tyres. They ride a bit hard, and dry out if you don't use them, but they're made in Europe, roll fast, last a long time, and have excellent at flat prevention for a tyre this light.
Scott Great all-rounder tyres. Excellent puncture protection, great grip
Mr Johnson Conti tyres are the best by far. Allow me to travel fast great grip for all terrain but most importantly on wet conditions. Love the tyres
Mr yoshida Light weight tire. I used GP400 S2 which was 25C. This time I ordered 23C because 25C was just too wide for me. This tire is very light and good performance.
Mr Matthews I have been using the Continental 4000's for several years now. They are a more comfortable tire than I had previously used and I average about 4000 miles out of them before needing replacement. On my fourth set. I also haven't had any flats since switching to these tires!
AlexM Can't say enough good things about this tire. Super reliable. I only wish Continental would release a tubeless version of it. 10/10
Mr Mills A good deal with the inner tubes. Not too heavy and tread is not obtrusive. Tyre inflates larger than the average which I like.
Mr Tyldsley Covered 200km on dusty roads with very good grip. Quality of the product, installation and performance have been faultless so far.
Mr Correa Martins Excellent tyres. Good grip and high performance. Using during 5000 km and still working very well.
Mr Bernat Excelentes cubiertas. Claramente las mejores que he tenido
Mr Thurlow Really the best tires you can buy given price, performance and wear.
jeffrey Best deal in tires. Consistently well-performing, long lasting, and frequently on sale. How can you beat that? Sticky in the corners, low-rolling resistance, good "feel".
Ken Good traction in wet or dry.. Low rolling resistance. Love these tires, changed all my road bikes to these tires.
Mark Great long wearing tyre. Best value rubber I have found with great performance.
DP Christensen GP 4000s Tyres are an excellent combination of durability, low rolling resistance and weight at a price that almost seems too good to be true. Then on top of that, Merlin Cycles throws in a free set of tubes and free shipping. Sign me up again and again!
Mr Bermudez Excellent service every time from seller. Best pricing and quality product. These are my go to tires, been riding for 6 years and ride until start getting frequent flats which is well into 3000 mile range.
Mr gray Noticed the reduction to rolling resistance straight away - very good value for money
Shantelle GH I was recommended these tyres by a gentleman at Pop Up Bikes, Manchester that carried out my bike fit. He couldn't compliment the product enough. I found them easy to fit, look smart and felt smooth to ride in. I completed a half ironman race with these tyres and had no issues with them. Plus you get two inner tubes as a bonus.
Mr Cotterell Love these tyres. Always my go to for training and racing! Merlin were the best price online
Pescado Pelado Great tires, these are my favorite to ride and race on day in, and day out! Best deal around getting a pair of these with a pair of tubes thrown in.
Mr Statham Great tyres and tubes, always dependable. Shipping to Canada seems without any hiccups.
andrew Great! Fast rolling tyres, easy to install. Still to see how durable against punctures, but if my four season tyres are anything to go by, they should be excellent.
Mr Perez Araujo The best quality for your wheels. Lightweight, endurance... there is no more options to choose!
FS These are my favorite tires both for performance and puncture resistance- I 100% swear by them and will not use any others! This was also an incredible deal on them, which is why I bought them on this website even though I live in the U.S.
Mr Jenkinson I've only done one ride so far - about 45 miles - and I like these tires. I switched from 23mm Schwalbes to 25mm and they do feel slightly more compliant. Along with their quality and performance, it was hard to beat the price!
Mr gray Could not believe rolling resistance could be so low
Mr GREGORIO My favorite tires! Very low rolling resistance. I am from Brazil and we do not have asphalt in good condition, but even so the GP 4000 SII is the best options in durability, grip and speed!
Mr Cuccaro Great tires at a great price, and bonus with tubes provided. Can't beat that!
Rozza Still the best by far. Comfortable, fast rolling, safe in all conditions. I have them on on my race bike and my winter bike and have done since they brought these bad boys out. Especially good with latex tubes.
Gabriel Romeiro Great tyres! They roll fast, corner with confidence. No doubts whether to buy them or not, especially with the frequent sale prices.
Mr Miguel Fantastic tires! Improved my speed and feel nice and sticky on turns. Now just need to see if they out do my last tires that wore out after 1700 miles.
michael These tyres are excellent. Really good grip in the corners. I even run them through winter.
James Best tyres on the market, excellent grip and good puncture resistance. Merlin was also consistently the cheapest supplier of a pair of these tyres. Very impressed and will be ordering again
Alain Very comfortable and sticky tires. I recommend them very much.
Sean Use these for all my road bikes. They have always been reliable.
Andy in MK Only done 3 or 4 rides on these but I can honestly say they're 1-2mph quicker than the stock tyres that came with my bike. They're easy to fit once you get the knack with folding tyres and they grip the road well. Usual outstanding price and service from Merlin.
Mike Low rolling resistance, easy to mount, overall nice tires.
Mr Lowe Excellent tires, I've been happy using GP's for several years. Good traction and life. Jumped for a pair of replacements at the recent sale, along with some free tubes.
Mr Ryan I've been riding on these tyres for a year now and have been very happy with them. However, I recently rode over a sharp edged rock and it sliced through the side wall, so I replaced with a spare tyre I had and opted to buy another two pairs. Process was quick and easy, delivery from England to Australia took a week and I am pleased to once again have back up tyres.
Mr Lim As trusted as ever. My go to clincher. Race and train on these tyres.
Mr McInerney I could not be happier with the level of customer service at Merlin. In addition, these tyres are simply my favourites so I have ordered four more.
MrGtee Superb tyres!!! I have tried them all and Conti GP4000S11 are simply the best all round tyre. At this Merlin special price I have just placed an order for 2 x more sets of these beauties!!! Get them while you can I say.....
Mr Caldwell I've ridden on Conti GP4000s II for years and love them. Super smooth and compliant.
Sam I wasn't sure whether a tyre upgrade would really make that much difference to my ride, but I thought I'd give it a go as these weren't much more expensive than the "cheap" tyres in my local bike shop. I considered Schwalbe One's, but these tyres are reccomended everywhere on the internet. Fitting was a breeze, no wrestling with a wire bead and I could immediately feel a difference in the ride. The tyre felt a little "tackier" to touch compared to my old tyre, and I was caught my surprise a few times at how much quicker my bike felt. I don't think I'd go back now!
Mark Second set of these I've had - reliable, fast, high mileage tyres - and great at the price I could get them for at Merlin.
Mr David The GP4000 is the standard. It might not be the best at anything, but it's the best all around. The twin-pack makes the tires an even better value.
Mr Smart Definitely the best road tyres that I have ridden. These were purchased as an upgrade to 25 mm and they haven't disappointed. This was the first time I had used Merlin, couldn't fault the service.
Uzi Ashkenazi Love these tyres! I ride in some rough roads here in southern California but these give feedback and hug the road! My new favourite.
Mr Daley Bought these in 23cc for my road bike on the back of great reviews and having switched to the Continental 4 seasons on my hybrid commute bike, which offered great grip and barely any resistance increase over the old slicks. Only one 50 miler completed so far and a thumbs up from me, obviously can't speak about their longevity yet though. Merlin offered best deal on the web too, as per usual.
Rupert Great price at Merlin. I've been told that these are simply the best all round training / race tyres. Tried them out yesterday. They certainly felt good!
Joe Great tires light and puncture resistance very high! Recommend!! And wow super price with tubes! Thanks Merlin
Daryn M I have used the GP4000 for around three years now. Great value for money performance tyre. Great value from Merlin as a twin pack
Mr R. These Contis are great. Have put about 1k on my current tires, and bought these as a backup when I may eventually need them. Smooth ride.
Mr Johnstone These tyres are simply the best. Any time I see these on sale I get them.
Mr Koga These tires are very fast rolling , which also means less watts per mile. Second set. Free tubes makes Merlins price for the pair about the best you will find.
blackbianchi Great deals for great products. These tyres made my bike feel super smooth and faster. Cornering at speed felt secure and easy compared to any "23" tyre I`ve used to date. Had to try to believe what a difference these larger "25"GP4000s 11 actually make.
Mr Wassong Always get the best price for road tires. The Continental 4000 tires are the best. Long lasting & roll fast. Great service at Merlin!
Terry Can't give these specific items a review as have bought to use when needed; however, I always buy these due to their longevity, low rolling resistance & avoidance of punctures
Dereck The order was shipped quickly, it got held up in Canadian customs. The tires are FAST!! I got the 28's for road tires with my Ridley X-Fire and they roll very very well.
Paula Top tyre that delivers great performance whether it's sportives or crit racing. Key to these tyres is getting the right tyre pressure, over inflate that are not as grippy. Top price,.
Mr stangherlin Excellent tyres, used them for about 200k, very absorbent on the crappy roads here in Ontario Canada, got the 25 mills absolutely love them
Mr VLAD I have tried out the 25 mm tires for the first time. They are great I really like them, much more comfortable than the 23 mm
Edwin Great all-round tires. I do recommend the 28mm if you can fit them on your frame. Granted, they do not have the best puncture protection, ride quality in inclement weather, or long term durability (can maybe squeeze out 4000km from them before all the sidewall cuts further develop into the tread), but they roll really well and make you want to keep on riding, unlike gatorskins or other energy-sapping stiff tires. Merlin offers a good offer that includes the inner tubes. You will need them as puncture protection isn't the best but overall a great summer tire.
Paul These are by far the best tires I've used (vs Michelin, Schwalbe, Vredestein). They are fast, comfortable, durable, and when you buy them from Merlin, inexpensive. The 28 mm tires are exceptionally nice but they run a little large. On my rims the 28 mm tire measures 31.5 mm. Make sure you have clearance.
A. Bez Great value for bundle pack. I was riding with them since 2016, only three flats I have.
Mr McBride Great racing tyre. I often train/ race in bad weather including downpours and I can descend comfortably as there is a good grip
Aidan Always use the GP4000s II great product, fast, reliable tyre and great delivery and value from Merlin.
Marko Hands down the best all round race and training tyres ive ever used in 20 years. When they square off rather than start puncturing you know this is motorcycle level quality
Gordough These tires are the gold standard in training tires. Very reliable, long wearing, and easy to put on and take off. The delivery and the price from Merlin's is second to none. Can't wait for the next sale which happens often.
Eymard Great tyre for racing and everyday use.
Jay The only tire I buy! Great deal with included tubes.
Balmore Loving these tires they are amazing. I may or may not have been biased towards them. No one hyped them for me I just wanted what the pros use. I had Bontrager R3s in 23mm before These GPs in 28mm. The difference is great. My first 14 mile ride in them was much faster and comfier. I would describe them as riding on a very slick gummy bear. Awesome tires get them stop thinking about it.
Mr P Where to start, super supple tyres. Feels like your riding Aladins Carpet over the rough stuff, yet stiff enough to give you confidence in braking and cornering. I have currently got around 3000 miles out of these tyres, with the exception of small surface cuts they look brand new still. The inner tubes are great as you can add 'Stans no tubes' sealant to them easily and live a (dare I say it) 'puncture free' lifestyle. I am a very much point and go kind of rider, so the tyres and tubes have stood up to a lot of abuse (even bunny hopping small obsticles in my way). I seriously can not recommend these enough.
Hugh Matthews These will be the fourth set of Continental 4000s I've used. They ride smooth and are very comfortable. Most of my riding is on rough back roads consisting of tar with crush and run gravel as a surface. The Continentals hold up well and have not had a flat as long as I've been using them. Highly recommend these tires!
Martin Great tyres at a good price. 4000+ km out of my last pair.
Fabio Nice tires, very light, nice grip and very fast.
Mr Greenwood Replacements for the same tyres that I have used for years. Will keep them ready for the summer campaign. Great longevity from Conti and can't remember the last puncture.
Mr Rillera This is my 3rd time to order this product very smooth traction, best to recommend
Kernewek I've got these tyres on both the winter and race bikes and cannot fault them. Great grip and never had a puncture (touch wood) since putting them on. I tend to cycle outdoors in all weathers and so they have had to put up with all of the rain, mud and road conditions (mainly potholes) of Cornish lanes and highways and haven't let me down. Wouldn't use anything else now and since I changed from the 23mm to the 25mm they seem to work even better, and slightly more comfortable as well. A great tyre.
Mr Knaresboro My go to tire. Great wear, great puncture resistance.
Peter Best tyre around wouldn't use anything else
Mr Kovács Still my fav, awsome rolling resistance, low weight and puncture proof.
Steven Great tire, I have several thousand miles on a prior pair, they wear well, grip great, and have not punctured after riding through glass.
Mr hague In my opinion these are one of the best clinchers tires available. They handle the road very well from cornering to wet roads and with the 25 mm I run less air pressure which makes the ride a little more comfortable. They mount on the rims fairly easy and another great advantage they last a lot of miles I usually will get 5000 miles on a pair and in that time very few flats. I have been running these tires ever since Continental introduced them on the market.
Mr Kim Wow, best endurance tyres and tubes at world's best price! I ride around 5000~6000miles a year and it doesn't wear out during a year or two.
Mr Fitzgerald Great all weather tyres with super puncture resistance and low rolling resistance
Geoff (New Zealand) The benchmark for tyres, love them, run at 70psi front and 80psi rear.
Scott Chamberlin I've used these tires in the past and love them. They have no equal, handle great, wear forever, and grip well. They are similarly useful for recreation riders and competitive stage riders. After searching the internet for prices on several occasions, Merlin won every time. Their shipping was free and the process was very systematic. Amazing service and value.
NT Great tyres which give confidence in bad cycling conditions. Best price online at point of purchase.
Jim in White Plains, NY My gold standard for road tires. Never fails to amaze me how much confidence I have in these tires to grip the road and resist puncture. Bonus tubes a plus.
Mr Ruta Great tires (tyres?). Great deal. I have them on 4 out of 5 bikes and plan to put them on the 5th bike when I change tires. They roll and corner well. The only flat I have had was caused by a bad valve stem.
Mr Boyer Fast and roll well. I prefer the Conti 4 Season Grand Prix because they take a little more punishment, but the GP4000s is a faster roll.
ALPAKURT I feel quite reliably self assured of an absolutely perfect tire:-) always my first choice (Continental GP4000s II ) I recommend all racing enthusiasts ;-)
Graeme Got these in 28c to replace schwalbe ones in 25c, virtually no difference in weight and these feel fast and comfy reducing road buzz well. A bargain at this price.
Mr Lam Conti GP400s II are always a solid choice. Good balance of durability, grip and rolling resistance. If there is one major complaint I had at the beginning, these tyres need to go through a break-in period. It rides incredibly rough at the beginning and is not very forgiving. Once you get a few hundred KMs in it, they're great!
Robert The standard tire for performance and racing. Great rolling and a very balanced clincher for road training and racing.
Mr Emslie Great tyres, onto my 3rd set of these tyres and loving them.
Mr Trachtenberg These are the best tires I've ridden. Supple ride, good handling, and wear well. Merlin's price is excellent.
Kieron Bought on the basis of reputation and wasn't disappointed. Excellent value pair of tyres/tubes package. No problems fitting. Ride is smooth, predictable and comfortable. Quite happily run at 70 psi but I will run nearer 90 for general use. Width comes out at little over 29mm on 15 mm rims
Mr FOUQUE Best overall tyres, incredibly durable. I ride everyday and change the tyre after 6 to 8 months
Mr Krol These are great tires! I've been using a pair for over a year now and they have about 6500 miles on them and am just now going to replace them. They've been great the whole time I've had them, never punctured or anything. I ride year-round in all kinds of weather, so these tires will hold up well!
Mr KENJI I use it for racing and training. I think that it is durable even in the racing tire. I used 3000 km and never had a puncture.
Mr Byard An old favourite the 700x23 roll well and seem to last a good distance. Good value with 2 free tubes
Jon Everyone knows how good these tyres are however the product is only part of the package. This package came with free delivery to Dubai where pretty much everything is three times the price of US & EU suppliers. Aramex (the better ME courier) deliver in the UAE on behalf of Merlin so everything is a win-win with Merlins International Service. Thank you.
Mr Knight I`ve been running GP4000s II since they came out and can`t fault them. They are easy to fit, grip and ride is better than any other tire I`ve tried. Excellent price and brilliant service from Merlin as always.
Mr Statham These road tyres are the staple on my road bikes. I never have flats compared to my riding buddies. The discounted price from Merlin's lets me always have spares when needed.
Hywel Used this brand for 5 years - wears best on the tarseal on New Zealand country roads. Increased to 28 mms width - roll superbly and very comfy. Good survice and price from Merlin
Ms Chaplin Beautifully made. I am a repeat customer of the continental GPs they do not disappoint.
Mr FREIRE Continental GP 4000s II are great, last long, ( use normally 7.000km ), great grip and fast rolling. It's one of the best.
Peter Love these tyres, I just keep replacing them with the same. Grippy and last well (7-8,000 km's for a rear for me, much more for the front). Only had one bad one which had a bulge in the sidewall and was replaced under warranty. I find lower pressures work better for a smooth ride, now using ~80psi on a 25mm and I weigh 84kg.
Mr Farrelly Great grip, fast rolling and for racing tyres, incredibly puncture resistant. Usually last me 8000km , through awful roads in Dublin and racing around the back end of nowhere, before I have to think about replacement and having used alternatives, there is no better all round tyre.
Mr Bryant I've used these tires for years and they keep getting better. Great price at Merlin, and the 25's provide lots of confidence and just the right amount or road feel and comfort.
David Great tires. Got 2,500 to 3,500 miles out last pair with one flat. My go-to tire without question.
Daniel These are my go-to tires. I've tried other brands and they just don't ride like the Contis and have never been as durable.
Travis Great tires. Roll fast, excellent puncture resistance and good lifespan. Great all-around performance in a high-performance tire! I ride these year-round in all conditions.
Mark First time I've tried the GP4000's having come from Michelin and Vredstein offerings. Pleased with tyres so far. As easy to fit as other brands and appear to have good road holding. Comfortable and quiet rolling too, but still playing with tyre pressures. Great service and delivery from Merlin.
Mr Reay These tyres have been recommended to me by other cyclists many times. Great puncture protection and great grip on the road in all conditions. Fitting was a breeze, both pushed on the rim easily just with my thumbs.
Mr Toblin These tyres are great! I have them on both my bikes and though I have tried other brands I go back to these every time.
Rusty45678 Gp 4000s, say no more. These are the best tyres out there in my opinion. Great grip, awesome in the wet and resiliency to junk on the road. My go to tyre for all my bikes.
Mr Smith In comparison to Kenda kriterium l3r pro which is what I was previously riding on, these are a dream! Granted I did jump from 25mm tires to 28's but I definitely could feel a difference in the rolling resistance and these tires create such a smooth ride!.
Hans G. The GP4000s II are a great tyre. Plenty of grip and they wear quite well. Also less cuts vs other tyres.
Mr Trindade Surprisingly great - very comfortable and smashed the myth of being slower than 23's. All together in the tested and proved Continental 4000. I will be good for another 4000k's.
Mrs Spearman Great tyres, long lasting and great in all weather conditions can withstand a warm up on the turbo or rollers before a race so no need to have the panic of changing wheel beforehand.
Mr Gallagher Great deal on great all weather tyres, great grip and performance
Mr Alli Fantastic tyres....I did a long Essex loop through country lanes filled grit and all. I'd probably have had a punture if not for the Conti's.
Mick The best tyres I have used over the last 4 years. Regularly achieve over 7000k on the front wheel and 4000 to 5000k off the rear wheel. Fantastic product.
James I'm old and slow. These tires are great. Put on the first set in May and couldn't pass up the great deal on this 2nd pair. Probably won't need them until 2018.
Scott The only tire I will ever use. Unfortunately the sidewalls can give out but it has been rare for me
Mr Odom These are my favorite tires now. Used to run the Continental Gator Skins, but have changed to these for a little lighter weight and very good performance on the backroads I ride.
Y. Keehm Now, I realize why many people praised GP4000s II, it's responsive at high speed and forgiving on rough roads. Quite happy to have them for my long commuting (~40km one-way). One note, I purchased 28mm. When inflated at ~90psi, the actual width is 30-31mm. If you have tight space between your frame, please beware.
Donald Amazing grip, in wet or dry. Fantastic.
Mr Fristad I have never had problems with these types of tires, they are the best.
Mr Calabrese These tyres corner well and are light weight with low rolling resistance. Best training tyre around and puncture resistant. Merlin's prices and service are great. The free inner tubes are low end, but what do you expect for free?
Ferreira Admittedly bought because it was a good value purchase. However I have tried numerous other makes but Continental remain the ones that work for me regardless of terrain and weather. Am reluctant to change.
Bunce Have tried a range of clincher tyres; I am pretty confident that these give me the best combination of speed, handling and reliabilty for decent roads and weather.
Burns I run these on our tandem as the 28 actually measures 32mm, and they provide a very smooth ride. The tread wears well but they are vulnerable to sidewall cuts. The deal on a package of two keeps the cost reasonable.
Mick B Superb tyres, with amazing speed and grip, buy them you won't be disappointed!
Rypstra I'm a fan of Continentals, waited far too long to go wider. A very fast, comfortable ride and outstanding traction. And last but not least, excellent customer service, cheers to the staff at Merlin Cycles.
Mr McGonigle Great reliable all-round tyres. Some of the best grip you can get. They measure up a little bit wider than most.
mazador Been riding GP4000s for a few years now. Great tire with solid puncture proofing and good durability (>10k km front, 4-5k km rear - 90+ kg cyclist). Switched to 25mm... increase in comfort & grip seems more than the +2mm difference.
Schroeder As I have come to expect... they perform wonderfully. The 25mm is amazing on my wider rims; I have a set of Bontrager Paradigm Elite (19.5mm bead) and they are incredibly stable coming down the canyons here in Utah!
Hancuff Best all around road tire on the market. Can always count on the GP4000 Series to perform, look sharp, and last a long time. Race, ride, commute. Great for everything and worth every penny
Phillips Second set of these tyres now. Good grip, last well and pretty fast. A good compromise between speed and reliability.
Mr Kilvington The best road tyre available. Good grip, lightweight and hard wearing. Others may be lighter or harder wearing but I`ve not come across any that do everything so well
Biketurn A fine tire. I have been using them for years. Durable, flat resistant and good handling
Mr Taylor I'd heard a lot of good things about these tyres so I thought I'd try them, I haven't been disappointed. Excellent road handling, grip and road rolling, they have made a real difference to my enjoyment of cycling.
Mr Christensen This is my second set of Grand Prix 4000s tires. Actually, my previous set was the 4000s, not the 4000s II. The wear indicators on the my 4000s tire on the front wheel hasn't even disappeared yet (I dare not say how long I've been using them, lest I get accused of not riding enough); that's an indication of how long they last. I tried some Michelin Krylion Carbon (good puncture resistance) and some Michelin Lithions, but they last nowhere near as long.
James Although I haven't enough experience with competing products to offer performance comparisons, I can definitely recommend the 25mm GP4000S II based on it's durability & longevity. I've racked up about 6000km on my first pair, and the rear tyre still has a fairly round edge, amazingly. It has survived everything from 50 to 300 km rides, temperatures down to 0 degrees Celcius, and plenty of impacts with stones, gravel and glass. Never had a puncture. None of the other tyres I've used throughout the last 20 years of cycling have lasted anywhere near this long.
Mr Demirgüreş Very good tyres. Grips well and protection is good. These are my second pair. I am not looking another tyres for coulple of years.
Matt H Have used 23mm for years, so 25mm new for me. On a set of Bullett 50s they seem to work well and are comfortable.
Mr Markgraf One of my favorite road tyres. Good mixture of performance, duarbility and value.
Clark The continental GP4000s 11 folding tyred are the best all round tyres that I have ever bought great for racing , long rides and have really good puncture protection
Powers Great tires. These are my second pair. First ones lasted me awhile. Got one flat when I first got them and didn't get another one till they were at the end of their lives.
SB Superb tyres - confidence inspiring
Ady Short Top tyre in all the write ups, durable and dependable, going with 28mm's provides a bit more comfort but for speed 23's are probably the better bet.
Theron Great tyres - have had them previously, tried some Vittoria Corsa G, big mistake! They felt sluggish & heavy (?more rolling resistance). Back to the GPs for me! Last forever & rarely get punctures, even on the dodgy Australian roads.
Mr Hutchins Excellent tyres, hardwearing, reliable, good puncture resistance.
ARW Transforms the feel of any bike you put them on. Roll fast but are compliant and absorb road imperfections. My favourite tyre, they give me massive confidence on fast descents. Puncture protection is excellent.
Mr Henderson Quality tyres. I wouldn't buy anything else
Mr Pannucci Can't fault these, they are my second pair, excellent grip and durability. Good value as well, when discounted!
Mr Buckle Great tyres of course, but my efforts to move to a larger size (up to 28mm from 25mm) have been scuttled. If you are considering the same size upgrade you need to do some bike measurements. These 28 mm Conti tyres don't fit on the rear of my road bike - they are just 2 mm too big. Fine at the front of the bike however. When I measured the width when inflated to 80 psi it was 29mm, by the way.
Mr skarratts This offer was too good to miss. I always use these tyres for every day riding and find them faultless. They cost a little more than others but this Merlin offer was even better with two free tubes included. Merlin service to this distant part of the world (NZ) was superb.
Mr Oliver Great race tyre with very good wear, I managed an entire season last year on a set. Would recomend the tyre to any racers.
Mr Yazman Buyers Attention! This was my first time with Continental Tyres, so if you see two small hole like things ((craters ?) on the surface of the tyre dont get panic and think you have faulty pruduct, it is the Continental way of wear markings, when you don't see those holes any more then it is time fore new tyres. Added inner tubes were nice bonus as well. Tyres look nice and light, bought 25c version for the fist time and already impressed. Will update when hit the tarmac again...
Mr dimitriu I have received the Continental Grand Prix 4000 S II tyres. These tyres were ordered for my son after I purchased the same tyres back in December 2016 and I am very happy with the product. I found them so far very good for most conditions I used them in the dry and wet conditions. Very happy.
Andrew Nicholls These tyres are great all rounders for road cycling - longevity, grip, puncture resistance, price and weight are all good so I keep coming back to them. Other tyres can be better for some of these features but not all.
Graham Tried a few other tyres but ALWAYS come back to these, roll great, fewer punctures and last forever.
Mr Connell These are the best tires I have used. Fast, great traction, long life and durable. The tread wear indicators are a great addition. Pretty much everything anyone would want in a tire.
Mr rogers I commute every day plus longer rides, after trying many different tyres I find these the best compromise, quick, good puncture protection, plenty of grip in the wet and good levels of wear.
Mr Mackie Great tyres, comfortable, grippy and fast, must buy (upgrade from Mavic/Bontrager)
Lee I always use these tires and love them. I got some new wider wheels and these 25mm are much more comfortable then the 23mm. I can`t say much more. The conti's are durable and fast. Merlin has the best prices and received them fast.
Mr Trindade This bundle combines one of the best road tyres of all time with 2 brand new inner tubes by Victoria! It is a no brainer. Great value for money, swift and quick delivery.
Steve-o G. The Conti GP 4000 SII are great tires. They provide great feel of the road and have fantastic grip. Puncture resistance is very good for a racing style tire. However, as they get well worn, the puncture/nick resistance begins to diminish. I'm a big rider (200lbs) and I usually get about 3000 miles before they need to be replaced.
Curypko Fantastic tyres - lightweight, puncture resistant, good looking and grippy. You need to be confident in your tyres when descending hills at 65 km / hr + and I am confident in these. Well worth the extra $5-10 per tyre over cheaper options.
David B Great value and I keep going back to these tyres after trying (too!) many others.
Mr Lunde I live in Sonoma County , California, USA. I purchase the Continental Grand Prix 4000SII because the black chili rubber compound is superior to the other tires I have used in the past. There is a lot of glass, nails, screws and other junk on the roads here and I find that I have fewer flats and longer tire life with the 4000's. I find that Merlin's prices are very competitive, and even though I live in the States, delivery time is more than acceptable. I will continue to use Merlin Cycles as my primary source for tires.
Mr SOLINSKI These are awesome tires. Great rolling resistance, longevity, and hardly ever a flat. Worth every penny!
Delfino These tries are the best I've ever used. Currently I have three road bikes and they all have these tires. Stick well to the road, the cornering ability is awesome and also good flat protection.
Mr Tran Excellent road grip. Very comfortable cornering aggressively! !! Great deal!!
Richard I can recommend these. I have them fitted to 3 different bikes including my commuter. I can get around 5000kms out of these. I have used them since they replaced the original 4000 s. I find that they maintain good contact on the road in all conditions. The rolling resistance is pretty good. Compared to the gatorskins I don't find the puncture resistance much different. Make sure that you use the right inflation. What can I say, I am happy with these and will keep using them.
Mr rosen Outstanding durability, flat resistance and handling.
Huddle Still my go to tires. They roll fast and pretty much never flat. Comfortable, easy to mount, light weight and durable for what they are. I use them on all my bikes for daily riding.
Sze The best road bike tire to get, period. Upgraded from Continental Gransport Race, and the GP4000S II is quite a bit nicer in terms of grip and comfort.
Mr Dyson By far the best Tyre on the market, great in all conditions
Mr Oxlee These are my go-to tyres these days. I use them on all my bikes, they wear well and inspire confidence, Definitely recommend.
Mr Ostrom Best all round tire. Tried some Michelin Pro 3 Race and I went back to these GP4000S II's.
ryansog Awesome grip in all weather, puncture protection is great only had 1 in 2500 miles which was actually my fault, running them too low
Huddle Another great price and quality product package. These tires are my go too favorites as they grip well, resist flats well, ride comfortably, and last a long time.
Mr Hales Good price for 2x tyres and tubes made even better with Spend & Save. Bought 25mm tyres and mounted on fairly wide rims so they feel pretty comfy. I ran them at 100psi for a 185km sportive and got no pins and needles in my hands (and no punctures!). The tubes have 48mm valves. They seem fine. Excellent service as always from Merlin.
Lee Still my favorite tires to date, super fast
Mr FOLLETT I`ve tried the others and these are still the best out right, cannot fault these tyres.
MickB Excellent all round tyre. Fast rolling and yet seems to resist punctures to a high degree. Tried several other brands (either fitted to new bikes or bought because on offer) but always come back to these eventually!!
Mr Chris Great price and delivery, this my second order for these, rear tire wearing out after 2000+ miles, one puncture, front tire still almost new! Bike rides noticibly smoother and faster. Best tires ever!
Mr Gardiner Great tyres and tubes at a great price. Personally I think Vittoria open corsa cx are better for suppleness and rolling resistance, but these are much better wearing.
Ms Lansky Great classic tires with little fuss, minimal rolling resistance, and minimal risk of punctures.
Mr Larocque Good racing tires. No flats after 1000km. Nice wear indicators.
Mr KOÇ Fast and durable tires. The best one I've ever used. I prefer the 23 mm on Fulcrum Racing 3 wheels (15 mm internal rim width) because 25 mm forms a bulb shape which is not good.
Andrew In 20 years of road cycling I'm yet to find a better (clincher) tyre. Fast, good in the wet and highly puncture proof, these are just the best. I reckon these are one of the 'great' cycling products to be honest!
Mr Duran After Schwalbe One's failure, I choose to buy Contis. So far I'm happy with them. They're reliable. Great price, as always.
Boase After riding tubulars for most of my riding I wanted to switch to a nice set of clincher wheels and tires.I finally settled on the GP 4000S II's. I was reluctant to switch because I was worried about the ride quality compared to my tubulars. These tires have been awesome, roll nice, easy to mount and so far have worn really well.
Tarbet After over 30 years of cycling these have been the only tyres I've used for the past couple of years. They are reasonably durable and the performance is unmatched by any other clincher I've used.
TrevC Great upgrade from stock Specialized tyres. Fast rolling, bike feels better. They seem grippy and tough too.
Marowitz Great tires. I get 4000 miles on a pair. Only extreme hazards cause flats, e.g sharp metal piercing objects... very rare.
Mr Bridle Was unsure as I usually use Schwalbe tyres all the time - however as they do not do Marathon Supremes in 28c I thought I'd give these Conti's a go and - have been really impressed - in wet and dry conditions - the handling is assured through corners and the 28c rolls lovely and makes the rough roads seem butter smooth - really glad I made the change and you can't fault the two free inner tubes!
Pistol Knight Best value and fastest tire on the market. Free speed with low rolling resistance. Seamless delivery. Well recommended.
Hallier These were an upgrade from the GP 4 seasons which I had been very happy with (no punctures in 5000kms). The new tyres are great, they feel a lot better on the road and seem to soak up the rougher road surfaces better than the 4 seasons.
Mr Dhunjishaw I was a little bit wary from ordering "across the pond", but Merlin Cycles came through, and then some. Got the correct package on time, well before it's stated date. Of course you can't beat the price either! In terms of the tires......I can only say that they are outstanding. Light, tough, and pretty damn good in the wet weather; typical of conti's I have ridden in the past.
Mr Jaffe Fantastic as usual, just a new pair for the shimano RS21 wheelset, have been riding these for a year and a half, on daily bike ride, great ride no failures.
Mr ellis They are my go to tyres, used others in the past but always return to them.
Mr Carter These replaced my Michelin Pro4 Service Course tires after numerous flats from thorn punctures. The new Contis roll fast and the upgrade to 25 width made all the different in cornering and comfort. The package price made the purchase even better.
McKivor Great tires. Low rolling resistance and seem robust. I ride mostly in the city where there's a lot broken glass and haven't gotten a puncture after almost a month of daily riding.
Royd Perfect upgrade from the stock Schwalbe Lugano set on my bike. I cut 10 seconds off my time on a 1.4 mile route with these tires. I love these tires.
Alqahtani The best tyres there is. I bought tons of these for my friends. specially the 23C. I personally prefer the 25C ones.
Mr emci This is my second set. First was 23mm, currently i'm using 25mm. Fast, durable, excellent tires. Thank you Merlin.
George B Excellent tyres that provide a smooth ride, nice grip and good durability. More than meets my general usage needs.
Mr Griffin Easily the best all around high performance tire made. Combination of grip, durability, and speed. Glad to see it is now made in 28mm too!
Mr Hackett Wow. Tried these after gatorskins and can really feel the difference. Fast and supple.
Mr whittingham You will not be disappointed with these as they offer excellent grip in both dry and wet conditions. Went for the wider 25mm option and the increased level of comfort was noticeable. Also roll very well. On the service side Merlin delivered within a couple of days, so full marks there......
Huskie I'm definitely tempting fate here !!! ButI've ridden nearly 500 miles on these tyres in the last few weeks. On my previous pair of well known branded "durable" tyres, I would have had about 5-6 punctures by now. Very happy with these, worth the extra expense just to save on the cost of inner tubes,
Mr Fayad Fantastic tyres. Grip like glue to the road in dry and wet conditions. Puncture resistance is bullet proof (up to 5000 Ks) You get great millage too! 25 VS 23: This is my first set of 25s, and I am impressed. A cushier ride without compromising rolling resistance (much).
Mr Moore These have become my go-to tires for both racing and training. Low rolling resistance yet with good durability and good value (particularly from Merlin which is typically 50% less than brick and mortar retail in the U.S.) Certainly on of the best tires made and nice to get a couple of tube also!
Jameson I have tried many different tyres and these remain my firm favourites. Good adhesion, long life and good puncture resistance.
Tim Best all round tyres! VVery good rolling resistance with great puncture protection. Now fitted on my winter, summer and race bikes!
Naccarella Fast, long lasting and dependable. I am 90kgs and they last 4 ,000 to 4,500kms. Which is really good as everything else lasts less.
Mr Nielsen Awesome tires, I've been using these for 2 seasons now.
Wyburd This review is for the 700 x 28 tyres. The GP 4000 have an excellent reputation, but my observations: 1. They aren't 28 - but 30 so clearances a problem for road bikes. 2. A "balloon" shape so a lot of tyre in contact. 3. Three punctures in 6 months of light use, one of those things perhaps, but not a strong tyre for the winter. 4. Soft rubber which expands as you pump to pressure ; when you get a puncture you can see the hole. 5. In my experience poor rolling resistance. 6. The Gatorskins [also a Continental tyre] which replaced the GP 4000s roll much better and comes out as a small 28. Also, oddly, a more comfortable ride. So for me these tyres have been rather a waste of money. Maybe the 23s and 25s are better, and I hesitate to give less than 3 stars to tyres which have such a good reviews elsewhere.
WillemToppertje Superb quality tires. Light rolling, good puncture resistance, comfortable road feel and confident cornering. Nice.
Joe Bennett Great set of tyres, very reasonably priced AND with a cheeky pair of tubes thrown in for good measure. Very happy cyclist! Very easy to install, and must say they're the stickiest tyres I've ridden - lots of confidence going into the corners. Merlin cycles got them to me nice and quickly too
Mr Sneaky Got these as a spare, yes they are that dependable.
Mr mclean Great tyres used them before no punctures on last set
Mr Hector Great tyres, much better grip than my Gatorskins. Bought 28mm to run at a lower pressure and certainly gives a more comfortable ride without any difference that I can notice to rolling resistance.
Mr Petkov I have been riding with these tires for the past two and a half years and the only issue I have had is that I wear them out. (ave 2500-3500 miles per season) Once worn past recommended thread level they are more susceptible to cuts and punctures. I have ran over rocks, sticks, metal pieces with confidence. Would like to see the price on the colored ones go down for me to get try them too.
Kev Rolls way faster than espoir elite 25mm. Measured almost 5% faster according to my GPS. Measured about 30mm on my 24mm wheels.
Mr Masker I've been riding these Conti's for over a year and leapt at the opportunity to buy another pair at such a phenomenal price. Merlin Cycles: Value Added! Thank you!!
floydo Great tyres! Have ridden them over 30,000 miles, and mixed in others, and keep coming back to these. For comfort, grip in all conditions, weight they are soooo reliable. Some have commented they cut more easily than a few others, but they all cut, and those others mentioned don't have the grip or feel these have.....
fmoser Fantastic tyres. Perfect fit for bike/wheels, easily fitted. Roll great. Ridden first off along a bit of gravel (no cuts) and on a long tarmac climb/descent. I was fully confident descending at speed on these. The 25mm size definitely added some comfort compared to last 23mm tyres
Mr Giacomin Fantastic tires, worth the cost. Noticeably stable around corners. And of course great service and delivery time from Merlin.
Mrs Blom Very happy with these tyres; being fast yet durable as well.
Charlie B I've been using GP4000 tires for about 7 years without any issues. The tires are reliable and last a long time, even on occasional gravel and dirt surfaces. The order process with Merlin was easy and I received the tires within a few days.
O'Connor Fast delivery, low price and two free inner tubes. Good deal. The tyres are my favourite for summer. Roll well and don't puncture easily.
Richie my 3rd pair, good reliable tyres. Trusty grip and handling in most conditions . Highly recommended
Mr Davidson I live in Arizona, USA and we have a lot of stickers or thorns. These tires did not do well with flats. I had 3-5 flats on each tire before I gave up on them. This was at probably less than 400 miles. Many that I ride with love these and that why I tried them but I had bad luck. Grip and ride was great.
Mike I've only previously used Michelin Pro 3 and 4 tires - so I'm no expert on all the different tires on the market, but after trying the original 4000s and now the updated version, I've been very impressed. In saying that, my first pair were very tight (too tight to get onto the rim and never really loosened up) but these new ones are that little big bigger and no problem getting on. They seem fast, wear very well compared to the Michelins, and I've also found the grip to be superior. So in my experience these are excellent all round and fast tires.
parkes Fast delivery and a great deal. As for the tyres I like contis, my local roads are rough country lanes with cattle grids etc and I am quite large so I went with 28 mm to replace the old giant 25 mm and the ride is smoother and more forgiving and they seem to roll a little faster over the rougher surfaces.
Mr o carroll Good value when bought as a pack with free inner tubes. I have used Grand Prix 4000s many times before and find them very good for grip and mileage. The only niggle I have is the last few I have had got damaged on the side walls (very thin) by random loose stones after the winter. I am not sure whether I was just unlucky or ran them too soft 90 to 100 psi, I have decided to run them at not less than 110 psi from now on in the hope that as the tyre rolls over a stone it will not slide off it and puncture through the sidewall.
Mr Malfait Great tyres. Used them to replace the Schwalbe Lugano's that came with my Caad8, and these are so much better. Quicker, less prone to punctures, and I feel much more confident on the bike, too.
walker I went for the 28mm version of this long established tyre and found them to be excellent in all conditions with the added advantage of slightly improved comfort without compromising rolling speed.
Luke For me, GP4000s are the best bang for your buck tyre around. I get awesome mileage out of them (up to 7000km a set, but I'm a lightweight!) and the only punctures I ever get are from tacks being laid on a local road by a crazy nutter who hates bikes. Plus the 2x deal offered is the best around.
Magic Mike Like the previous 4000s but better. In the 25mm width they roll well, grip well and are comfortable - just the job.
HONG Great tyres for daily use as well as long distance riding without trouble. Many cyclists are using 4000 S II with many good reasons.
Gil Switched from my 25mm Schwalbe Duranos and loving the difference - 28mm work really well on the roads in my area. Great service from Merlin as well.
nycebo Great tires that are quiet and roll well. Very good at absorbing impact and seem pretty puncture resistant.
Mr annicchiarico After having tried many brands and types of tyres, I have found the Continental GP400 S to be the best all rounder. I seldom get punctures, they last a long time and offer a smooth comfortable ride. If its quality and value for money you are looking for, look no further.
Mr Parsons I've fitted these tyres to my cross bike to improve my road riding. They are noticeably lighter, faster, and more comfortable than the predecessors. I'm running 90psi in the rear and 80psi in the front and find this very comfortable and grips well too.
Mr Baykal This tyre is really fast and you can trust on corners. Also very durable with wonderful puncture resistance
RDemap Awesome with improved traction hence better handling especially in the corners with the wider 25mm's. Rotating weight slightly increased but negligible. I would go with the wider width for training and racing any day. Highly recommended
Shaull The continental GP4000 S II's are the fastest, most durable tire I have ever experienced for a racing road tire. There are tires that are more durable, but you will sacrifice the lower rolling resistance of the GP4000's. You just can't beat them. I have used michellin pro 4's and had problems with flats, but the continentals last and last with over 4k miles just last year. If you want speed and the confidence of continental durability, these are the tires for you.
Mr Bazarte I bought these tires at one of the cheapest prices you can find online for a pair of continental GPs2 tires and on top of the low prices, they threw in a bonus pair of free inner tubes to match which is awesome. The continental GPs2 tires have great traction with low rolling resistance, I didn't understand how you could have the best of both aspects but these tires are the real deal. I only buy continental GPs2 for my road bikes and these are my 4th pair. Long lasting and easy to fit tire, can't complain.
Gary J (Brisbane, Australia) Continental Gp's are the best road tyre you can get. I keep trying other brands from time to time but the Gp's are my baseline......, and to be able to pick up a set of 28mm GP4000s was fantastic. They will go on my cyclocross / come commuter (during the CX off season). Great product - great price. Great service
Mr Leonard Much quicker than the Durano tyres.
Jenkins My go to tire for racing and training. Durable but fast.
Glingani These are fantastic tires and the bundled price is well worth it. Best tyre I ever owned! Comfortable, resistant for punctures, low resistant rolling. The best!!
Ryota Great all round tyres. Use them for races as well as commuting. Best part is its easy to put into your wheel. The rubber is soft with plenty of grip , yet it lasts longer than the other brands. Another good part is its pretty good in the wet as well.
Merwin Great tires. I was shocked the first time I put a pair of 4000's on my bike by the difference in speed and comfort from stock tires.
Mr moore Best tyre I ever owned! Last long, light and great for all weather.
Little Bought these for my winter rides, they feel really comfortable over rough roads and the grip you get is spot on.
Ms Frederiksen These are fantastic tires and the bundled price is well worth it. I have never had these tires before but they got great reviews on the Merlin website, as well as other websites. I'm a recreational cyclist and these are racing & touring tires, but I wanted to give them a try. I had difficulty mounting them to my H Plus Son Arechetype rims despite using good techniques. Finally had to resort to using tire irons to get them on. Initial ride feels good, although I'm not sure that I am a "sophisticated" enough rider to discern any glaring differences from my other tires (Panaracer Pasela 700c x 32). I am still playing with the tire pressure also. Overall they seem to be good tires, but I haven't had them long enough to really give an in depth review. Thanks.
Mr Mallion I use these for commuting and training. GP4000 remain my favourite tyre, from a grip in the wet, feel, comfort and speed point of view. (Is there another view?) Since first using GP4000s I've tried Vedestein Fortezzas (fast but sketchy in the wet and they don't seem to wear) and Hutchinson Fusion 3s, tubeless (no punctures but also sketchy in the wet and a bit uncomfortable, despite running them at only 76psi front / 80psi rear (I'm about 67kgs) they feel a bit on the non-compliant side). Put it like this: in damp conditions I never fell off on GP4000s but did twice on the Vredesteins.
Mr Nguyen Grippy, supple-feeling, and fast. You won't find a race-ready tire of this quality for much cheaper
Emborsky Purely a racing tire, in my opinion. Not as cut resistant as the gatorskin, but a smoother ride.
Mr Williams Very good quality, nice fit, a bit heavier than my last pair but much thicker on the middle section of the tyre so should get less punctures. The two inner tubes that come free with the wheels are good quality.
Mr Willis They were very tight to get on the rims but now that I've had a decent'ish run out on them I am very happy with the grip (wet road conditions) and they seem to roll quicker than my previous stock tyres.
Mr Hughes These tires have been great. It seems like theses tires last forever, control in corners are great!
Darren Rycroft Having shifted some time ago onto the 25 m tyres and found them to be much more compliant on longer rides due to the lower tyre pressure I am able to run, I had hesitation in fitting them to my new Giant TCR. Once again, the resulting rides over longer distances are less fatiguing than rolling on 23m tyres....Very happy so far and haven't had to use the free tubes supplied with them!
The Colombian Outstanding value tyres. My experience with these has been much more reliable than even the higher end winter training tyres made by Continental itself.
DK I reluctantly tried the GP4000 as a race tire. They tend to weigh a little more than advertised, but roll super fast and smooth, and so far seem to be relatively puncture resistant compared to the average racing tire. The tubes that come in the twin pack aren't of equal caliber, but who couldn't use a couple extra tubes? The twin pack with the tubes is a value so good it's tough to beat.
Coppers These tires are light grippy and puncture proof. Great price and service as always!
Rob These are the best road tyres on the market. I have tried many brands but always come back to the price I could find on the web.
Mr Hall Best all around road tire out there!
Pierre In my book, the best tire on market for the price and absolutely for long life. Being 235 lbs, I'll ride them 2,000 miles and then give them to a few 160 lb guys that will get another 1,000 + miles. Great construction, extremely minimal flats if properly inflated. Gold Star !!
Pete Coupled with the RS81 wheels, this was a very good investment. I felt a big difference with start-up speed. Compared to stock tires for Allez, this one is lighter and somehow picks up speed quick. it's not too flashy and does its job very well. I'm happy with the tires.
Newick Have used thes tyres for many years. They have good wear, puncture resistance and are comfortable. After trying many other brands I always come back to these. Highly recommended.Other riding colleagues have been converted too
Rowe On my second set of these. Perfect balance of speed an comfort. Outstanding grip. Faster feel and more compliant than vredestein senso. Can't compare puncture resistance as neither have punctured on me.
Mr O'Gorman Thoroughly reliable tyres with great performance. I use these all the time on my training bikes.
tierney Tyres are the best I have ever used, very hard to get a puncture with them. They are very fast.
Mr Misner I went through two pairs of these tires last season without any flats. I put on over 3000 miles on each pair. They are great all around training and racing tires.
Miguel Bought one pair for road racing bike and another for my Tri bike. The old tires went to my training wheels. I have yet to get a flat them. Nice riding tire.
Mr Martin This is the tire I always use. I get about 8,000 to 9,000 miles on the front and at least 3,000 miles on the rear. Good ride and durable. I ride 9,000 miles per year.
Morenz Best tires hands down. Excellent grip and traction for racing and great durability too.
Tom Buckle Order received in good time. Love the Continental Grand Prix 4000 S II 25mm tyres - they are noticeably more comfortable than the 23mm version when ridden at 90psi . They are not much heavier, and seem to have the same low rolling resistance.
tierney I have had several pairs of those tyres, I feel they are nearly bomb proof as I have yet to have a puncture with them. I find them very fast and safe.
Ben Light, reliable, durable, good resistance to puncture and assure you a good adherence even in wet or rough conditions.
Tim Good rolling tires. Happy with my upgrade.
bleesta Arrived 7 days to Canada. Easy to mount. Soft supple rubber compound. Smooth rolling fast tires for my road bike.
Mr Toumey I ordered this set to replace my previous pair. These tires hit the sweet spot in terms of ride quality, longevity, speed, grip, and durability. I usually get between 4000 and 5000 km out of these tires without any major damage. The tread compound is grippy to the point that, if I didn't race on tubulars, I would not hesitate to race on these tires. If you run them between 80 and 90 PSI, the ride quality is pretty good. Note that for pressures above 90 PSI, I've found that the ride quality is harsh (I'm 64 kg). Finally, the two free inner tubes just sweetens the deal by giving you two spares. The tubes are heavy, but you're training on them, right?
Phil H Moved from Schwalbe Extremo to Continental GP4000 S II recently. Rolling resistance is just as good and cornering feels much more secure. Have added Pit Stop to the tubes even though puncture resistance is reportedly very good.
Mick Absolutely fantastic! Good rolling resistance and good grip!
Mr Gerling As usual, a very good tire for almost all conditions. Conti GP4Ks are my favorite for training year round and racing on wet or rough roads. The two free tubes that come with them are nothing special but fine for training. I use a lighter tube for racing.
Konnagan I've always had great luck with GP4000's and it's been the same with these. Roll great, stick to the road. No need for anything else.
Hanghill A relatively light and modestly treaded tyre that will perform better in wet weather than slicks. The tyre appears to be quite thin so no convinced it will avoid punctures as well as some other brands/types, nor will the tread cut through as much water as some tyres. Good for fast damp conditions but probably not the best choice for the more extreme wet and cold conditions that the winter will bring.
Mr Young Just used these tyres to ride up the Stelvio and Gavia excellent ride and superb grip on the descents even in the wet. Highly recommended
Mr Taylor The gold standard for all-round tires. Fast rolling, puncture resistant, plenty of grip and light enough
Mr Parry A step up from the earlier GP4000S which I used for years. Great traction in all conditions and low rolling resistance.
Mr sells Had these before and are really great autumn/winter Tyre definitely have good grip in wet damp conditions and rolling resistance is hardly noticeable compared to slicks
Mr Adamson I had run a set of the GP4000s on my bike for 4000 miles without any problems so had no doubts about replacing them with the newer version. They roll fast, have good puncture protection, last well and most importantly give confidence in both wet and dry. Price was as good as I could find and got 2 conti tubes free and the service from Merlin was as good as you get. Happy all round
A J I have only owned these tyres for a short time, but I can agree with the other positive reviews. The tyres feel much lighter than the ones I had previously. They are also easier to fit over the rim. The 25mm width brings some welcome comfort and seem to roll just as fast as 23mm tyres. They use some quality rubber and have given me extra confidence when cornering. An added bonus is that they came with quality inner tubes. A great price and excellent service from Merlin Cycles too! Totally recommended.
Mr Allan The best tyres I have ever had - fast and very durable. Two years and still puncture free. Now I am going to try them in the 25mm version.
Mr Smith I ride in a city with some very beat up roads. Thought I would give the 25mm a try. Went out on some bumpy roads and found these held up very well, and the comfort level was nice too. Always impressed with Continental products and always satisfied with Merlin's service. Highly recommend.
Mr john One word FANTASTIC
Miss Elliott These tyres were recommended by so many people after a number of punctures so I took the plunge. Bit tricky to fit but so far so good. Free inner tubes were a bonus.
Mr Chan This is not the first time I used this tyre; I did try another brand before but my experience I got to replace it after only a few months or ride; I switch back to continental one. I believe that it should last for at least 1 year (~5000km for my case when I first used 4000s tyre) and in turns will save my pocket.
Mr Rowntree Brilliant tyres, this is my second pair for my summer bike would highly recomend.
Matheson Superb tyres, light, responsive and reasonably puncture resistant for the weight. I've used them for years. Recommended. Unfortunately the inner tubes are too heavy and not a good match for the tyres. So I'll save them for winter.
Hitz Not much to say about these. Thousands of miles on GP4000 tires and never an issue.
Houlton Arrived promptly and as ordered. Seem to have good grip in all conditions so far and seem to ride nicely - happy with my choice!
Mr S Received them within a reasonable amount of time, certainly worth the wait for this price. I've only had them for about 3 weeks, but after 300k of riding on both paved and accidentally gravel roads, the tires seem like a worthwhile upgrade from the stock Mavic tires that came with my wheels. Note: the 2 free tubes included are generic, not Continental brand, although I'm sure there's no real difference there. These tires are obviously the most popular road bike wheel out there, and Merlin has them for the best price anywhere. No complaints.
Mr harvey Moving from 23 to 25 makes such a big difference to comfort /grip and even speed. As always good price and speedy delivery from Merlin!
Moore Great tyres once they're on but very difficult to fit on Mavic Kysriums. Need to think seriously about if I'd be able to get one of theses back on after a puncture in the Mendips at 0 degrees on a January morning..
Lee Jones Fantastic, fast rolling tyres. I bought them in 25c but they inflate quite fat. More like 27c but man do they roll well.
Mr Chateauvert Great value ! These last easily 2000 km
Mr davies Excellent tyres for racing or training.
simon Super fast, very little rolling resistance. You could feel the difference immediately!
Mr Hampton Killa tyres! Conti's are great value. Roll smooth and last well considering the roads I ride
Potter The tire is new and seems much quicker than the old tire, but the old tire is worn down and has bigger contact patch. Still, the new Conti's are impressive and seem to roll much faster. I got 25 mm this time, a previous order I got the 28mm and those didn't fit most of my bikes. No problem so far with 25mm. As my other bikes tires wear out, I'll replace them with Conti GP4000 black chili as they are simply the best tire I've used so far.
Mr Miller These tires have become my go to tire. Previously used Gatorskins and these offer similar levels of flat protection while offering a more grip and comfort on the road.
Mr Nguyen My favorite tires. Smooth, comfortable, and grabs the road.
Mr Marchant Had several pairs of these so far. I buy them as I can't find anything wrong with them. I'm no pro rider, but I know when a bike feels stable and has plenty of grip. I use these all year round, and can't recommend them enough.
Mr Wilson Very good rolling resistance, great comfort, best tyres I've ever used for long distance
Nicco62 How good these tyres are hardly needs more comment. They do flat more often than the Grand Prix 4 Season and don't weigh any less, but they have a much more supple and grippy feel. Very hard to get onto my Pacenti SL23 tubeless-ready rims; fine on normal clinchers. The free tubes are 60mm and pretty heavy (ca 120 gm).
Lahiri Great pieces of kit! Swapped to these for the first time tonight in a 10 mile TT and instantly took over 3/4 of a minute of my PB to go sub 24 for the first time! Money well spent, highly recommend.
Sebastian With the opportunity to test a lot of different tires, I have yet to find a better work house tire like the Grand Prix 4000 S II. These are reliable, durable, and very rarely get any flats even on rough roads and under heavy fire from debris during the winter/spring in Utah. Though they're certainly not as supple like a vittoria or challenge, they're perfectly capable in tight cornering and "feel" plenty fast enough to handle any road race. If you don't want to run a training specific tire and race specific tire, this is the tire to go with. It can handle it all and last a very long time doing so.
Mr Davies Great deal on this pair of continental types, once you ride with these you won't settle for anything less.
Mr Mawby Great tyres. grippy, easy to fit, reasonably robust and puncture proof, pretty fast rolling. Tyres are by definition a compromise, but these are a pretty good combination of features for racing, training and everyday use.
Drew These really are the reference for best all round tyres. Good weight, good grip and great puncture resistance.
Ko I highly recommend these tires to anybody who is looking for an upgrade or replacement. These tires are super grippy and yet smooth. I feel less discomfortable and able to maintain my speed and go faster.
Mr Bailey Everyone loves these tyres - and with good reason. Stands up to punctures, rolls well and grips in the corners. !
Julesy-C Easily the best tyres that stick to the road whilst increasing performance. 25s are the new 23s.
Mr Connell Best tires I have ever used as well as a great deal. I will be ordering my tires as well as othe cycling parts needs from Merlin. Great prices and fast delivery to USA.
Mr Knight These are great tyres. Fitting was easy (but not TOO easy) and they roll beautifully.
Mr wu Fourth set I've purchased and used. The first lasted over 4,000 miles. Great bundle deal, especially when compared with single tire price at LBS.
Graham Easy on, only 200miles use so far but no issues at all and grip is great. Last set did over 2000m with no problems & only 1 puncture
Mr Kruger Quality tyres, good grip in all conditions. A must have in the wet
Mr MIYAZAWA There is only this for a tire. This is best!
Mr Murphy These are the best tires I have ridden on by far. They offer a soft comfy ride while providing great adhesion to the road through tight corners. I can rely on these tires on steep windy descents to hold a line without the worry of slip or roll over. They are also extremely durable. I managed 8000k on the first pair without a single flat and they're actually still in decent condition. I highly recommend these tires.
mamiloz Great tyre. Long lasting and excellent puncture resistance
Colin - Sydney Australia Continental GP4000 S II - Hard wearing, reliable and fast and with the bonus of a couple of spare tubes makes them great tyres for Junior racing on Aussie country roads.
Mr Karagoz These tyres roll really good and make you feel safe whilst taking corners. Not used enough to comment on their durability, yet.
Mr Swaine Bargain price for a well known performer. Great tyre with good rolling speed and grip. Haven't used in wet yet, kept on the tt bike as a race tyre for triathlon.
Mr Evers Great tires...good resistance to cuts and punctures. Really grip well in corners and I get a good amount of miles out of them.
Mr McGrath So much grippier in both wet and dry than my old tyres, and really unbeatable value. Can't comment on durability yet, but with quality this good in other areas, they're worth it
Mr Park The best overall tires I've ever used on a road racing bike.
Anonymous Excellent. Fitting was easy. Rode 60 miles on first trip and found the wider tyre gives a smoother ride with better grip on corners and no noticeable reduction in speed. No punctures so far!
Miss Platt Fabulous tyres, look great and grip well on the road. After me and my cycling partner both (thats 4 hands) struggled to get the original tyres off my bike when I got a puncture, I took my best mates advice to get rid and get these. Fitted them the night before a 55 mile sportive and loved them all day, smooth on the flat and grippy raking over into corners. Even rode with less pressure (80 front,90-100 rear) and was as smooth as anything. Highly recommended.
Mr Hesbrook This my first pair of Continental tyres after using virtually every other brand including open corsa CX over the years. These are quality straight out of the box. The 28mm tyres really are significantly more comfortable than my previous 23mm tyres. Check your frame clearance though. They ride superbly at 90psi. I cant praise them enough and will probably stay with these tyres for years now.
Andy Lee Great tyres. Better handling, speed and comfort in the 28mm size than the same tyre in 25mm. Best price on the web as usual from Merlin.
Mr Allan Moved up to 28mm from 25mm. Low rolling resistance is noticeable, more comfortable and no real negatives for me as a 40+ year old.
Mr Sari I didn't ride long enough but on daily rides, these tyres are real deal. They have both comfort and handling also it has a good protection on bad surfaces. I expect them to be good but it is beyond my expectation. These tyres are good choice for both long and short rides.
Mr Mammone I first tried Continental GP 4000S 11 2 years ago, I ride approximately 300 plus kilometres per week having tried other brands these are the tyres I feel most confident in even descending at 70 plus km/h compared to other tyres I seem to get less punctures and these appear to roll better and appear to have better grip around corners. Very happy with the product unless something better value for money comes up I will stick with the GP 4000 S11
Perth Cyclist The standard in road tires. Bought to replace older 4000's - I wouldn't use anything else.
Mr Blair Sticky, realky grab the road. I can't speak to their durability yet.
Mr Dolman I have observed a noticeable improvement with these SII tyres compared to my weary GP4000S in that they seem to roll further and the walls seem stiffer. Very happy to do business with Merlin Cycles too.
Kyle H Have been running the GP4000 series tires for a while now and have nothing bad to say. They offer decent flat protection until they start to get really worn and they roll quite quickly. Great deal on a set of a rubber!
Mr Lewis Great tyres, roll very well, super strong and puncture resistant, this is my 3rd set now.. great bundle price too...
Ultimus Your go-to clincher tires for british bumpy roads. May not ne the very fastest, but they do survive munching glass day-in, day-out...
Mr Stallard GP4000 S II - Amazing tyres. Get them, you won't be disappointed with the performance and puncture resistance.
Mr Whittle As usual...... great prices and fast delivery. These Continental GP's are great tyres, I must have had 4/5 sets over the last few years - never have any trouble with them, ride well, comfortable, roll well, easy to fit, pretty puncture resistant (don't tempt fate!), really great tyres.
Mr popov Great road feel, but the apparent lack of any sidewall protection gives me some concern regarding durability down the road.
Mr Doswell I've been running schwalbe on my winter bike but after a series of punctures decided it was time for a change. The tyres feel fast on the straights, and almost sticky in corners. I also like their softer feel, seem to smooth out the vibration from the road. I can't comment on puncture resistance yet, they have only done 100 miles. The inner tubes I probably won't use, they have extremely long valves and feel heavy.
mr bob Benchmark road tyre. Rolling resistance doesn't seem quite as good as I remember, will try the crosa cx for main summer duties. Ive tried a few various top tyres and somehow always come back to these. Wish the tpi was higher and they made a more supple version of this.
TiCoyote These are the best tires on the market. They last forever. They resist flats. They're lightweight. I'm partial to the 25mm size for lower rolling resistance and a smoother ride.
Mr Thunell Best tyres around in my opinion. I have never flatted on these.
Mr Osborne Fantastic tyre. Excellent absorption of bumps on the road and very nice rolling resistance.
Mr Eaton I bought these as I had used the older version 4000s and thought they were excellent. Well in true Continental style the latest version 4000s II are equally good. These tyres are best used IMO on a summer bike. Plenty of grip and fairly lightweight makes a great combination for a road tyre.
Mr nixon Best racing/training tyres out there. Great in all conditions especially wet.
David Excellent tyres, easy to fit, low rolling resistance. One of the best upgrades you can make to your bike!!
Mr Barton Excellent tyres and grip. I have a set on all my Raod Bikes and so do many of my friends. Good Price at Merlin Cycles as well
Allan R. Love Conti tires! It really does feel like these roll smoother and with less resistance. They last a long time too, great tire, highly recommended!
EK Great tyres, gripped well in wet race conditions
Mr Persaud Best tyres ever purchased to date - superior grip, smoother ride, lower rolling resistance. Questionable quality of free tube provided.
Mr Willetts Have replaced last three sets of tyres with these, and at this price they represent great value
Mr Coombs Great tire! It has a secure and smooth ride. It also has great flat resistance.
Mr Tracy These tires are amazing, in the 25mm width they are fast and comfortable with great life
Mr SISON I just converted from 23mm to 25mm and I am not sure there is a difference. The performance is definitely not lower at least in ideal conditions. I think the advantage of the 25mm will show in rougher roads and wet conditions.
dtube These are the best tires. I've tried many and always go back to this. Fast shipping to the States too.
Mr K So much grip ! Much more than the yksions they replaced. Quick delivery, best price from merlin.
Mr Dawes Awesome tyres, real grippy in the dry but haven't had a chance to test them in the wet just yet but if they're just as good or better than the 4000S Mark1 then they'll be awesome
Jon Clements Brilliant tyres. Second pair of these I have bought: first pair lasted over 1000km and over many back roads and country lanes; second pair have only been used for winter crit racing so far and never threatened a skid or slip even in wet and near-icy conditions.
Terry R Second set of these tyres. I find them to be excellent, both in dry and wet. Ridden over 1500 miles on first set with no problems. Would recommend these tyres and Merlin for their great prices and service.
Rob Ordered the new GP4000S II tyres late in the day and Merlin delivered the following morning, excellent service. The tyres are just as good as the original 4000S tyre with what seems to be better rolling resistance and I find their puncture resistance so good I use them all year round. Also got these at the best price I could find anywhere in the UK, thanks Merlin.
Mr Brown After 6 rides and as many punctures on the stock tyres that came with my new Giant TCR Advanced Pro 2 I've now done over 200kms on these without any! My old bike had a pair of the older models and they were brilliant so its safe to say these will be too!
Mr Musial These tyres are the best that I have used for years. Their low rolling resistance is very noticeable and the quality is great. They are now my first choice for bicycle tyres.
Mr Lee Mounted these on my Mavic Kysrium SL wheelsets more easily than my go-to Michelin Pro4 Endurance tires. They measure at 29.5mm, a pleasant surprise because I had read online that Continental tires tend to be narrower than advertised. Perhaps Gatorskins and 4seasons run small, but these GP4000s are as wide or slightly wider than the packaging indicates. Took it for a short ride to test 'em out, and the extra width really DOES make a big difference in ride quality. The roads I ride on tend to be pretty rough, and compared to 23mm it felt like I was riding on air! The Yaw tubes I have no comment on, a tube's a tube. At first I was worried that they wouldn't fit, being rated for 18/25c, but they seem to fit 28mm tires and hold air just fine after three days. They weigh 98g each, for anyone interested. This combo is highly recommended for anyone looking for 28mm tires that still have a whole lot of racing spirit in 'em.
Mr Parker These tyres are light, quite tacky, grip the road well, roll well, and my last pair lasted around 7000kms.
Andrew H. Best road tire you can buy. Grips good enough to race on, lasts long enough to train on.
Mr Meyerowitz Love these tires, the GP 4000s II are even better than the originals. They roll incredibly well. Great flat protection and the Chili compound makes then stick to the road!
Mr Nguyen Tires seem stickier than last generation. Good price.
Mr Noyes Outstanding price for these tyres even before the bonus tubes. I've tried other brands a spate of punctures has me back with the ever reliable and grippy Continentals
Mr Curley These are great tyres. Excellent grip, long lasting , good puncture resistance and light . This is my fourth set - I would not buy any other tyre . All year round tyre . The tubes have a long valve stem and seem overly heavy buy the set is great value
KK I was looking to change tires after always getting flats on my Vittoria Diamante Pro Lights. These 4000Sii's are great! You immediately can tell that they are more puncture resistent by the tire material. There is a little more rolling resistence but they are grippier and more comfortable. I would highly recommend these tires.
Tincaalot I don't use these tyres myself as they are a bit too upmarket for my useage. However, my son swears by them for his road racing, hence I bought them for his birthday..sssshhhh.
Mr HAWES Pleasantly surprised as to the difference in comfort upon riding with these tyres. Initially I thought I had a puncture because of the more cushioned effect than my older tyres. Excellent product.
Mat Boulton The Continental GP0400S II tyres are probably one of the best tyres around at the moment for everyday and/or race use - a great combination of light weight, low rolling resistance and puncture resistance. I previously ran the GP4000S tyres but upgraded to the new version when my last pair wore out. It's too early to tell if the II's are a major step forward but they are certainly as good as the older version. Time will tell on longevity but hopefully they will wear at least as well if not better. An all round tyre - one of the best on the market. Unfortunately the free inner tubes are absolutely rubbish - heavy and unsupple. Don't ruin the ride of your bike by fitting these - give them away to your local charity or throw them in the bin and buy some decent tubes to compliment the tyres!
Mr Palmer The quality of the Conti Grand Prix 4000 S II tyres is phenomenal. I won't ride anything else.
JC Good Value - Great tyres :-) Not used the tubes yet, they are the longer valve type. Have these on two wheelsets now - 25mm and 23mm. FAST tyres and confidence inspiring when cornering - roll well - grip well and seem pretty durable too :-)
Mr Huang Nice upgrade from my stock 23's. The 25's and the soft rubber allow for much more vibration dampening. I recommend upgrading to these or any 25's as it improved my ride quality ten fold.
Mr Watson Great tyres, now on my third pair.....would not buy any other tyre .
Wayne After many years of cycling I've come to the conclusion that tyres are the quickest, cheapest and most noticeable upgrade you can make to a bike. Assuming the wheels are in good condition and half-decent but not necessarily expensive (think Aksium etc..), tyres play a massive part in keeping the wheels rolling with less effort. These tyres are by far my favourite. They're light, comfortable, roll beautifully, and have some degree of puncture protection. Coming from the S version I think the S II is superior. I wish they were cheaper but you get what you pay for.
Mr Garside I usually use Mavic tyres until now! The Conti 4000s II are grippy, fast rolling and very comfortable! I went with the 25mm tyre size to give myself a little bit more confidence and these give you just that in abundance!! In the dry I can't fault the them in anyway, as for the wet, I've not yet tried but have heard great things. I also received two inner tubes too, bargain! Great price, best around infact, so look no further if you've already made your mind up on your tyre choice. Add to basket, purchase and wait for them to arrive (which was so quick that it felt like I received then before I ordered them!). Outstanding service from the Wizards at Merlin.
Mr Keane Brilliant product, never failed yet and this new issue promises the same
Mr Stainsby Great tyres bought two sets.
Steve C Melbourne AUS Bought these in 25mm to replace 23mm GP4000S tyres that have been GREAT. The new ones will allow lower pressure for a softer ride (95psi instead of 110psi front) with negligible extra weight (225g instead of 205g. I weighed them at 219g) and no loss of speed. Looking forward to fitting and riding them.
Sean Lam Fast shipping. The tires came folded and held together well by a band, which was also easy to take off. The tubes are also great quality. I had no trouble installing the tires onto my wheel, and they roll great!
Mr Murphy I've been a big fan of Conti tires for quite some time and these new 4000 S II will continue to keep me coming back. They offer a smooth soft ride with a grip youu can trust in any tight corner at speed. With my last pair of Continental Grand Prix's I managed 4500 Klms without a puncture or flat. Great tires. The tubes offered with the bundle however are sad. They're very heavy and poor quality. I ordered three pairs of tires and tubes and had to use these tubes on a friends bike. 2 out three tubes were leaking. One through a hole at the valve the other a hole in the rubber. I gave up and gave her a spare I had from another manufacturer. I wouldn't feel comfortable giving these tubes away.
Mr whymark Well it is not often that I am that surprised by a product. To be honest it felt like I was riding on butter the first time I took the bike out with these on, lovely, soft, fast reduced vibration, I had some decent Vittoria 25mm on before but these are worlds apart, with some inner tubes thrown in, added to super fast delivery and of course the best price on the net, what is there to think about?? Go get some. Thanks Merlin!!
Mr Carson Fantastic tyres and tubes. Went for the new updated version of this tyre after the last pair had seen me through nearly 4000 plus miles! Super grip and great confidence building going into corners!! Best price on the internet I could find plus the two free inner tubes made it a great deal.
Mr Jackson Great tyres - fairly easy to fit - excellent grip and great rollers - never going back to Schwalbe
Johnny Y. A great tyre in its previous incarnation; now even greater.
Mr Mc Donald Brilliant tyres with fantastic grip and durability. Life savers in the wet.
Dr Lee Superb tyres. I'd been using Schalwbe Marathon Racers for 5 years (1 puncture). These aren't that much lighter, but about 3 mph faster, and more comfortable. Waiting to see about the punctures.
Mr Ford Awesome tyres, loads of grip they seem really sticky, I bought them as they are renowned for their puncture protection but only time will tell. The free tubed even looked like continental as they had orange caps which was cool.
Mr Philbrick These tyres are superb, they roll well and you don`t get punctures. I recently bought a new bike and the fist thing I did was take off the tyres and put these on. I won`t use anything else. I use them for training, sportives, and triathlon.
JimmyD These are my go to Tyres. On all of my 4 road bikes. Durable and trustworthy
Mr Murphy All good so far, run smoothly, no punctures yet and quite grippy. Had a bit of a fight getting them on though!
Simon I have been using Continental's GP4000 tires since several years, and I keep using it because it is durable, provides a good grip to the road and is fast.
Mr Joyce These are true sizes and roll extremely well. The chilli compound and high tpi casing is a definite plus as to feel of the tyre on the road. Good quality tyres at a very good discount places Merlin at the top of my radar.
Mr Mallon The continental GO 400 S II tyres are great tyres! They look good, were easily put on and roll well when on the bike. I'very only just put them on so hard to give much of a performance review but put them on and did a 98 mile cycle with no problems at all. I like these tyres.
Leo Awesome tyres, long lasting and grippy
Mr bishop Very pleased with tyres, was rolling on 23mm gators before, these seem lots faster and really smooth out the roads. Went for standard delivery and received tyres next day, excellent service
Mr Nugent Upgraded to these as older models (gp 4000s)were starting to wear out. Not one puncture was had on those tyres so don't expect any on these! Fantastic all round tyre
Mr Broadbent Best tyre going, perfect split of race performance and toughness.
Gerry B Got these to replace my old GP 3000's and immediately felt the difference! Roll better, corner better and give a bit of zing I really need. Best price here at Merlin too and free tubes, what's not to like?
Mr Bingham Not been fitted long, gone on couple of rides one in wet, got good grip, seem to roll better than tyres that came with mavic wheels. These are a bit tighter fit than mavic tyres, need levers, these have a bit more comfort for me maybe because running lower pressure
Mr Cleary These are great lasting tyres and the puncture resistance is excellent, only need these through normal wear and will continue to use Continental, great tyre!
Mr Scott Continental GP4000S in any version are my go to tires for Sportives. I've got a set on each pair of good wheels I own.
Crankmasher Only done a few hundred miles, but seem to roll very well and no punctures as yet, despite hedge cutting. Very pleased
Mr Wells The new GP4000S II are another great Conti tyre. First time I've used 25 mm tyres...I won't be going back to narrow tyres anytime soon!
