I've been using these tyres for both racing and training on for a few years now, having raced TT's, short & Ironman distance tri's, as well as coast to coast, Lands End to Jon O Groats. These tyres have performed impeccably.
They provide incredible grip and reliability, especially on fast mountain descents in the Alps.
These are without doubt my choice of tyre.
The price offering from Merlin makes them an absolute bargain buy.
Very nice tires! Great grip, smooth rolling! And it looks really good on my bike!
Great tyres, and at this price I run them all year round. I know exactly where I am with the grip and how far I can push it. They do have a tendency to have small threads appear (probably a technical term for this) which can unravel like a wooly jumper if caught on something. I find I get more than an acceptable amount of wear from them and would purchase again and again specially as Merlin were yet again cheapest on the net.
Fantastic tyre. Normally run Gp4000s but these have proven to inspire more confidence at high speed cornering
Excellent price and fast delivery of these well approved tyres. I fitted them the same day and they went on easily. I have only ridden the bike twice due to the weather but they seemed quick, very smooth and although I was a little wary of the fact that there was no tread they gripped very well on the wet road surface.
Great tyre, good wear and puncture resistance
I have been using these tyres for a few years now and won't buy any others, they are fast and provide a predictable ride
Very light, fast rolling tyres. When I first used these I was concerned that they would puncture on a regular basis, however, I have pretty much worn my first set out with only one puncture. They don't last as long as other tyres available but for the level of grip and the speed they roll at it is still worth every penny. This is now my third set. Recommended
The monthly magazines I get rave about these tyres, and they are not wrong.
I've bought quite a few of these in the last few years and am very happy with them.
Light, fast and reasonably puncture resistant.
This is a super light-weight, and high-quality tire. I have been using these for a long time, I did with these thousands of kilometers without any problems... One of the best, I recommend this product!
IMO the best 3 season tyre...and at a great price. Superb grip, wears well. Never punctured one yet.
Great tyres and fantastic price.
This year I've used Open Corsa's and loved them, only trouble is I've gone through 6 tyres, very prone to punctures and tear up quickly.
Tried a pair Conti 4000s tyres, felt dull and lifeless.
Got a pair of Ultremos sometime in Sept, using them with Mich Latex inners and so far totally trouble free, fast smooth and grip well, looking at them now they will probably do winter, a firm reco....
GOOD FOR RACING - TERRIBLE TERRIBLE TERRIBLE FOR COMMUTING.
These tyres are light and fast. They grip well and look great.
HOWEVER and a big HOWEVER, do not buy these for commuting. They're definitely not your 'up and down the freeway tyres.'
Rode them 46 miles in the rain for the box hill sportive, no complaints, plenty of grip up hill, ridden some tyres up hill with plenty of slipping, these were great, fab colour (bought green and white version). I`m no pro, but should meet my needs as not out daily. Great value Great prompt service too.
Great tyre definately the fastest tyre I have used, durability is good and has good cut resistance the. Only thing I can pick on with this tyre is the sidewalls, which thread tends to come off on all the zx tyres I have had but I just cut it off and doesn't seem to affect them!
Brilliant tyres for those who want a fast, no fuss addition to upgrade their bike.
I've been riding these Ultremos for around 7000 miles, and although I've heard about some problems others have encountered, I have found them to be nothing short of outstanding.
Factor in that the great service from Merlin offers a par of these cheaper than anywhere else, and you have yourself a winning combination.
Rode these at the Box Hill sportive today, 46 miles in the rain, appeared to have plenty of grip and up hill too, better than some for purpose tyres. Rode at 80 psi.
Look great, ride great, that's one ride though, but, happy I am.
Have used these tyres before and really like them. They look good, last well and roll quickly. Even though they are totally slick, I used them all last winter with no mishaps.
Great deal from Merlin, and really fast delivery, but that's come to be expected from such a good retailer.
Fast rolling tyre. Good grip in all weathers.
Great all round road tyres. Being a mountain bike rider I was quite surprised how sure footed and well they grip in the wet. I got about 2,700 miles out my last set.
The tyres are extremely grippy though not pushed hard in wet as yet. The have a very good range of air pressure max 140 to suit a whole range of rider weights and wheels. I only use quality tyres so difficult to differentiate fully - all I can say is they performed perfectly and felt slightly more spritely than the GP4000S set I usually ride on.
Web site and pricing from Merlin very good -- the order processing and delivery (standard) is first class, beating the competition.
Excellent ride quality, grip up there with the best.
Great tyres, really smooth and quick for 100+ miles :)
Great tire, comfortable due to good width and volume compared to some other, similar dimension tires. Super light weight and good grip but can be prone to cuts.
Fast, light & grippy.
Not the most robust tyre, so beware of pot holes and glass. But if you're careful, you can ride these puppies for a good few thousand miles.
Bought to replace the same tyre where I've managed to damage the side wall. Been using these for the last 18 months with no issues. Light, fast and importantly, easy to get on and off the rim.
Excellent tyre, real quality great performance combined with light weight
Couldn't get these tyres anywhere else (only merlin had the 25mm size) - ordering was easy and tyres were delivered v quickly using standard post. Tyres are great, extremely grippy on some tricky downhills. Would recommend both the tyres and the store.
Love these tyres, excellent grip in both wet and dry, good puncture resistance and theylook great on my cube.
Terrific tyres and the extra size from 23mm to 25mm made no noticeable difference on the rolling speed but a lot more comfort on a long ride. Merlin delivery, as previously superb.
Excellent product. Exactly as described.
Colours are bold and bright.
Recommend this product to anyone.
300 miles per week.
Tend to be Quick on descents and Ultremo ZX are sure footed.,they tick all the boxes.
This tyre doesn't get good reviews for nothing. It rolls well, has good grip and is fairly robust for a race tyre. I have changed two recently due to cuts in the contact area, but no P's, so the HD protection seems to be working
Light and good looking tyres. Great price!
Been using ultremo zx tyres for the last few years for summer/race use. Very quick tyres and seem to last reasonably well for a race tyre.
These tyres are brilliant! I had these standard on my bike and they lasted for a good year. I recommend these as I only had one puncture and that was down to the the end of the life of the tyre. Well worth the money to keep your wheels rolling! :-)
The ultimate road tyre, super light and still very durable.
Great race tyre! lght, grippy, responsive and fast. Would not recommend for training though as they (in my experience) puncture quite easily!!!!!
Great Tyre, never had these before but I thought they were really good they held me upright cornering on loose grit and going at speed downhill. They seem to roll better than the last tyres I had as well which is always a good thing.
Definatley purchase these again
My third pair of Schwalbe ZX tyres. Great tyres in wet and dry conditions, and I have them on my winter hack, my tourer, and my carbon 'speed machine'. As usual, Merlin Cycles provided an excellent service, with good prices and ultra quick delivery.
Great tires. Roll fast and have good grip in turns. Merlin delivered to US really quickly and at a great price.
Great price... Perfect
Awesome light durable tire.
Good tyre never let me down. Excellent grip on the wet. I had before Contis which are equal quality but the ZX has a tougher sidewall lower rolling resistance. Speedy delivery to New Zealand, Merlin Cycles its magic.
Second set of these, that says it all. Grip well, as good as any puncture resistance and look great. Brilliant service from Merlin, with prices too match.
Great product, great value for money. Thanks Merlin
Excellent tyres. My previous set had just completed Lands End to John O'Groats without a puncture. Whilst they may be designed for racing they really did work well on my secteur. Gone for 23c and white lines to match the bike. Excellent service from Merlin - next day delivery. Cannot be faulted.
Read the reviews and i am not disappointed with these tyres. Early stages regarding puncture protection, but grip and ride comfort is outstanding. Top service from Merlin as always and prices that make them unbeatable. Been using Merlin for years and pointless looking elsewhere for cheaper prices or better service!
Great looking tyres at a great price
Excellent quality tyre, good grip and rolling resistance, certainly seems to make the bike more responsive. Will definitely buy these tyres again.
these are nice grippy lightweight tyres which I like a lot. The ones with a carbon stripe tend to always be a bit cheaper so I always get these. The service was outstanding from Merlin very quick delivery
Went for these after many good reviews and so far they seem to be good. Only used them for a few weeks so far but feel fast and grip is good.
These tyres are excellent ,lived up to all the star reviews.Very quick,rapid delivery from merlin .well satisfied.
I have used Merlin Cycles for 2 or 3 years now they are always competitive on price, the service is great and the website is straightforward. Hence why I use them when there are plenty of others to choose from.
My third pair. Love them. Light, good value for money. Especially the full blacks.
Great tyres at the best internet price.
Great set of tyres. Superb quality and look great on my bike.
The best tyre, durable and beautiful.
Bought these tyres at a very good price from Merlin, they are mush lighter than my previous tyres (Durano S) I have completed 200 miles on them so far. Great light weight, fast tyre.
Excellent product,fast shipping. A1 service
Excellent tyres and excellent value. Light, easy to fit anv very grippy in the corners. Upgrade bought to accompany my Aksiums and the package makes the daily commute much quicker.
great all round tyre, great mix of light weight, low rolling resistance and durability.
Can cut up a little but I wouldn't buy anything else for the summer bike
So far the tyre rolls nicely, no problems with cuts or punctures
Very happy with this, i wanted some faster rolling tyres which stood up to punctures. Had them for a few weeks now, ridden through all sorts of poor road conditions in Scotland and the Lakes, no flats, roll quickly and turn into corners noticeably quicker than my last lot - almost caught myself out a couple of times.
All in all, very happy with them.
best tyres i have ever bought, fast and quiet.
Bought this to replace one that had the sidewall slashed on a cyclepath that was being repaired. Great tyre hence buying again has made a great difference on my rides out much smoother and rolls alot better. and the price at Merlin is by far the cheapest around.
Superb...light, very fast rolling and give real confidence in the corners. They look great as well!
super grip from these tyres, you can trow the bike into a corner knowing the tyres will hang on. They really inspire confidence and allow you to push hard on fast decents. The compound is verynhard wearing with no cracks or slits after a few hundred miles. They are a little pricey, but you cant have a 4k bike and put 10quid tyres on it.
Tyre was amazing but the service was even better.Thanks Merlin cycles.
Great service from merlin as always
Thanks very much +++
Tyres are very good quality and good value for the money
The drink is also good I will definitely be using this webste in the future and recommend it to my friends
great tyre, if a bit soft
As always excellent service from Merlin - delivery following day after placing order.
Ultremo ZX's have really good reviews in various articles/forums and so far have lived up to expectations with quality of ride/grip. Haven't use them for long enough to test durability.
These tyres are a very tacky compound and particularly good in the wet. I'm not sure of their durability as they're new. Also the red and white writing on the sidewalls look great.
This is a great tyre, I have used this in the summer, mostly wet in our area and never had a problem. Would recommend to all roadies on a budget.
Haven't used the tyres yet but a great price and fast delivery.
took a bit longer than expected but no worries quite satisfied good price and products will order again in future
excellent with immediate delivery
I bought the Schwalbe ZX tyre in plain black as was recommended for best grip and roll. They won best tyre in Cycling Plus magazine. They are a very fast rolling tyre (I believe to be one of the fastest on the market) and have transformed the ride on my Bianchi which now flies.
Merlin's service was top notch with delivery within 48 hours. I have since referred a friend who took delivery of his tyres next working day. Thanks Merlin!
i just bought these as i wanted a new set of tyres to do the 100km dartmoor classic. less chance of getting a puncture.
and as for rolling resistance claims from schwalbe i have only just joined the yogis cycling club in plymouth so i'm riding pretty much at my limit with them.but i did get comment from one of the other riders that he was having to pedal to keep on my wheel whilst i was freewheeling on a few occasions.
Having read a few reviews and discussing faster rolling summer tyres with friends and fellow roadies, I took teh plunge and ordered a set.
I have been so pleased with them that I ordered a second set for when my first set wear out.
Positives: Fast Rolling / Look Great / Easy to Fit / Great Price from Merlin.
I cant comment yest on how long they will last, but I have nothing but praise for them so far.
Prompt delivery as usual,regular user!
If these are better than the R.1 then match them with latex tubes for the most cost effective upgrade to your bike.
Fantastic service. Tyres arrived the following day. Will continue to use Merlin. Prices are very competitive. Keep up the fantastic service.
They do exactly what you want: grip well in the wet and the dry; inspiring confidence in the corners. Good value tyre. I cycle a lot over badly surfaced town roads to get to my training area and they have a number of cuts on the surface as a result of the glass etc...but not a single puncture since getting them. The only tyre I now use.
Merlin delivered them super fast with my new wheels too. Excellent all-round service.
These tyres are the best I have used. As much grip as the Michelin Pro 3's but don't cut up anything like as bad-in fact no cuts at all so far. Roll really well and my tyres of choice from now on. Went for the all black ones which look great with the carbon deeps
Really nice feeling tyre, looks good rides well and so far no punctures after about 800 miles. I'd certainly go for these again.
Very supple excellent grip
My friend and I were riding Land's End to John o'Groats (982 miles) and both put on a new set of Schwalbe Ultremo's for the trip ... 4 wheels, 2000 miles, 1 puncture = enough said. These roll well and seem durable.
Great tyre, top road handling and look fab on my zipp 404's. i only use schwalbe ultremo zx tyres because of the good quality and puncture resistance on long rides.
These are fantastis tires, I had a set before and never experienced a puncture in all the time I used them , which is brilliant as they are a racing tyre.
So far I have done around 400 miles on them, great rolling efficiency, no puncture so far, I would buy them again, best price on Merlin cycles.
Nice and grippy in both wet and dry... light weight and look good too. No punctures as yet (5 weeks), and for only
Great tyres, very grippy with minimal rolling resistance and weight. Not yet tested for puncture resistance, which in itself is a good thing. Highly recommended. Usual high standard of service from Merlin.
Tried many tyres over the years including the recent Michelin Pro Race 4, these tyres win hands down, they're not a training tyre though, as whilst they have great puncture protection the rubber can get cut up if you ride through a lot of debris. But you don't buy a top end tyre for training so it's a moot point...look after them and save them for race day and you will fly...
Bought these tyres in the sale,delivery from Merlin was prompt as usual, fitting them was very easy no tyre levers were needed, and they look superb on the bike, very light tyres.
