Special offer for 2 Continental GP4000s II folding 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, BlackChili 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.

General information about our shipping
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.
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.
Best tires hands down. Excellent grip and traction for racing and great durability too.
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.
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.
Light, reliable, durable, good resistance to puncture and assure you a good adherence even in wet or rough conditions.
Good rolling tires. Happy with my upgrade.
Arrived 7 days to Canada. Easy to mount. Soft supple rubber compound. Smooth rolling fast tires for my road bike.
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?
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.
Absolutely fantastic! Good rolling resistance and good grip!
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.
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.
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.
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
The gold standard for all-round tires. Fast rolling, puncture resistant, plenty of grip and light enough
A step up from the earlier GP4000S which I used for years. Great traction in all conditions and low rolling resistance.
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
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
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.
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.
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.
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.
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.
Brilliant tyres, this is my second pair for my summer bike would highly recomend.
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.
Not much to say about these. Thousands of miles on GP4000 tires and never an issue.
Arrived promptly and as ordered. Seem to have good grip in all conditions so far and seem to ride nicely - happy with my choice!
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.
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!
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..
Fantastic, fast rolling tyres. I bought them in 25c but they inflate quite fat. More like 27c but man do they roll well.
Great value ! These last easily 2000 km
Excellent tyres for racing or training.
Super fast, very little rolling resistance. You could feel the difference immediately!
Killa tyres! Conti's are great value. Roll smooth and last well considering the roads I ride
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.
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.
My favorite tires. Smooth, comfortable, and grabs the road.
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.
Very good rolling resistance, great comfort, best tyres I've ever used for long distance
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).
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.
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.
Great deal on this pair of continental types, once you ride with these you won't settle for anything less.
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.
These really are the reference for best all round tyres. Good weight, good grip and great puncture resistance.
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.
Everyone loves these tyres - and with good reason. Stands up to punctures, rolls well and grips in the corners. !
Easily the best tyres that stick to the road whilst increasing performance. 25s are the new 23s.
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.
These are great tyres. Fitting was easy (but not TOO easy) and they roll beautifully.
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.
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
Quality tyres, good grip in all conditions. A must have in the wet
There is only this for a tire. This is best!
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.
Great tyre. Long lasting and excellent puncture resistance
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.
These tyres roll really good and make you feel safe whilst taking corners. Not used enough to comment on their durability, yet.
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.
Great tires...good resistance to cuts and punctures. Really grip well in corners and I get a good amount of miles out of them.
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
The best overall tires I've ever used on a road racing bike.
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!
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.
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.
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.
Moved up to 28mm from 25mm. Low rolling resistance is noticeable, more comfortable and no real negatives for me as a 40+ year old.
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.
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
The standard in road tires. Bought to replace older 4000's - I wouldn't use anything else.
Sticky, realky grab the road. I can't speak to their durability yet.
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.
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!
Great tyres, roll very well, super strong and puncture resistant, this is my 3rd set now.. great bundle price too...
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...
GP4000 S II - Amazing tyres. Get them, you won't be disappointed with the performance and puncture resistance.
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.
Great road feel, but the apparent lack of any sidewall protection gives me some concern regarding durability down the road.
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.
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.
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.
Best tyres around in my opinion. I have never flatted on these.
Fantastic tyre. Excellent absorption of bumps on the road and very nice rolling resistance.
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.
Best racing/training tyres out there. Great in all conditions especially wet.
Excellent tyres, easy to fit, low rolling resistance. One of the best upgrades you can make to your bike!!
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
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!
Great tyres, gripped well in wet race conditions
Best tyres ever purchased to date - superior grip, smoother ride, lower rolling resistance. Questionable quality of free tube provided.
Have replaced last three sets of tyres with these, and at this price they represent great value
Great tire! It has a secure and smooth ride. It also has great flat resistance.
These tires are amazing, in the 25mm width they are fast and comfortable with great life
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.
These are the best tires. I've tried many and always go back to this. Fast shipping to the States too.
So much grip ! Much more than the yksions they replaced. Quick delivery, best price from merlin.
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
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.
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.
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.
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!
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.
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.
These tyres are light, quite tacky, grip the road well, roll well, and my last pair lasted around 7000kms.
Best road tire you can buy. Grips good enough to race on, lasts long enough to train on.
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!
Tires seem stickier than last generation. Good price.
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
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
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.
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.
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.
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!
The quality of the Conti Grand Prix 4000 S II tyres is phenomenal. I won't ride anything else.
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 :-)
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.
Great tyres, now on my third pair.....would not buy any other tyre .
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.
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.
Brilliant product, never failed yet and this new issue promises the same
Great tyres bought two sets.
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.
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!
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.
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!!
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.
Great tyres - fairly easy to fit - excellent grip and great rollers - never going back to Schwalbe
A great tyre in its previous incarnation; now even greater.
Brilliant tyres with fantastic grip and durability. Life savers in the wet.
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.
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.
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.
These are my go to Tyres. On all of my 4 road bikes. Durable and trustworthy
All good so far, run smoothly, no punctures yet and quite grippy. Had a bit of a fight getting them on though!
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.
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.
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.
Awesome tyres, long lasting and grippy
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
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
Best tyre going, perfect split of race performance and toughness.
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?
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
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!
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.
Only done a few hundred miles, but seem to roll very well and no punctures as yet, despite hedge cutting. Very pleased
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!
