About as perfect as clinchers get.

When it comes to helping customers pick out their ideal gear, there are few definitive answers. On the subject of tires, however, when customers are looking for a tire that can and will absolutely, positively improve their riding experience, there is a consistently correct answer in the vast majority of circumstances: The Vittoria Open Corsa EVO CX III.

The "III", of course, indicates that this is the third generation of the Open Corsa EVO CX that was a favorite already when it debuted. It's only gotten better now, and we can heartily recommend it for a number of reasons.

Of foremost importance is the fact that "Open" means - in Vittoria's parlance - that this is an open tubular tire. While a standard clincher is engineered from scratch, an open tubular is a clincher made by splitting open a tubular tire. You'd think this would mean some degree of compromise somewhere in the design, but not in this case, because while most open-tubulars are a notably heavier that standard clinchers, the CX IIIs weigh in at only 219 grams (23mm version), putting it only hairs above the lightest of the market's non-open-tubular clinchers.

So what advantages does being an open tubular bring to the table? First is amazingly smooth ride quality. The sky-high 320 threads-per-inch count of the CX IIIs translates into an incredibly supple tire, acting as a more pliable casing with higher shock absorbency then the usual 100-200TPI you'll find on the vast majority of clinchers out there. The high TPI rating increases cornering traction and speed, as well, by allowing the tire's shoulders to conform to the tarmac with greater fidelity, as opposed to a stiffer, less-compliant profile of a tire with a relatively more brittle casing.

Indeed, the Open Corsa is a "cotton" tire in the classic tradition, but it's also received some notable upgrades to make it more durable than the racing tires of yesteryear. Each of the tire's 320 threads-per-inch are actually individually spun around a filament fiber, creating a yarn strand and what's called Vittoria's Polycore layer. The result is a far more puncture-resistant casing than a traditional cotton tire normally does, so you can have the smooth speed and cornering of a classic tubular with the durability - and convenience - of a modern clincher. One last bonus of that high thread count: excellent air retention, so you won't need to add nearly as much air into the tires every day - although checking your pressure before every ride is something we still strongly recommend, regardless of which tire you choose.

The Vittoria Open Corsa EVO CX III Tire is sold individually in either 21, 23, or 25mm sizes, and in the colors Black, Blue, Red, White, and Yellow.

They are OK

  • Familiarity:I've used it several times

Look, they are supple, they feel great, they corner as if on rails. But after just a few hundred miles they look trashed - the whitewalls are more like taupe-walls and there are splits and cuts everywhere. I bought them as race day only tires but even for that purpose, they are an expensive proposition for how quickly they degrade. As soon as they are unrideable (likely soon), I'll go back to the trusty GP4K S2 - the ride isn't quite as nice but it is still very good and the combination of performance, durability and puncture resistance really can't be beat.


Grip, predictability, confidence

  • Familiarity:I've put it through the wringer

I run these in 25s. They wear a bit quickly, and what you trade in wear you get back i grip. These are my go-to tire, and I've no intention to change.


Vittoria Open Corsa is top shelf

  • Familiarity:I've put it through the wringer

I bought these as racing tires. The Open Corsa is arguably the best tire you can buy for rolling resistance, which is what happens when your energy gets soaked into deforming the tire as it contacts the road rather than pushing you forward. For example, to go the same speed with Gatorskins vs the Open Corsas you have to constantly work about 20 watts harder. That's a lot of power wasted. Buying a racing tire is the cheapest way to get faster with no additional effort. Because the tire is soft, the cornering has (so far) been superb. In fact, I've never ridden a tire that could inspire as much confidence as these in a turn. But the very virtues that make them great for racing means that they're going to wear out fast and probably flat more often than a training tire. To minimize the chances of a flat, I run latex tubes. This not only helps even more with rolling resistance and comfort, but latex is better able to tolerate little pokes from whatever slivers I pick up.

When training, I leave a Vittoria on the front--front tires hardly wear at all--and a Continental 4000S II on the back. This lets me have fun cornering while still providing decent rolling resistance and puncture protection where it's usually needed most (in the rear). Even so, the Open Corsa picked up little slivers of rocks while the Conti so far has no marks or cuts. So, again, this is a soft and delicate tire that will reward those seeking speed and handling, like racers--this is NOT for people who value durability.

Is this tire the same as the Vittoria Open Corsa CX III Clincher Tire? If not, how are they different? Thanks.

please it would be nice if you could answer the question? still waiting a year later.........



I think the CXIII doesn't have the ISOGRIP rubber for cornering. I haven't tried the older version so I can't speak to whether the new tires are better, but the latest iteration feels superb and confidence-inspiring while slicing through turns.

Just ordered the Open Corsa EVO CX and the box states Open Corsa CX-III. Compound is ISOGRIP. 320 TPI is indicated as the Open Corsa EVO family.


Best crit/road racing tire

  • Familiarity:I've put it through the wringer

I have been on a quest to find the ideal tire for crit's and road races. My goal has been to balance rolling resistance, aero, cornering, handling in wet conditions, puncture protection, and a variety of sizes. This is that tire in my opinion. These are the best i have found in really sharp corners and in wet conditions. The rolling resistance is right at the top of the best tires out there and windtunnel data suggests its not hurting you either. The puncture resistance is decent when they are new but understand that they have around 800-1000 miles of life before they are compromised. Also do not ride these on the trainer for warmups before races, you will drop the tire life by a few hundred miles quickly.


Racing Tire

  • Familiarity:I've used it several times

I've been a continental guy for a long time, loyal to the gatorskin for commuting and the grand prix 4000 for general training and racing. As a bold risk taker apt for for venturing into the unknown, I took at shot at these so I'd have a better base for comparison between different brands.

Thus far, I'm impressed.

"Tubular like feel" its pretty cliche, but it totally fits here. Very, very firm grip in the corners, ridiculous low rolling resistance and surprisingly puncture resistance are the big advantages here. It's been a tire I've been using at weekly crit races, and team rides, and I'd consider it a racing upgrade over the Grand Prix 4000.

Now durability is where I'm still a bit skeptical. They're holding up well so far (about 500 miles), but we'll see how they compare to other brands after more heavy use. Will be back with an update on that later, but for now I'm loving them!

Any update on how these wear? I ran the open corsa evo cx iii clinchers, and they wore quicker than i would've liked. I've ridden about 1,100 miles on these (able to calc bc of strava), and they're worn.

Update on wear: not as durable as some other brands. After about 900 miles I had a few flats and they just weren't going to last for me. Awesome ride for those 900 miles though. Would run these again.


My Favorite Race Tire, Plus Training!

  • Familiarity:I've put it through the wringer

I have ridden all the top tires and due to it's traction, superb supple casing, and fast ultra low rolling resistance, this has become my favorite tire. The only down sides are they are pricey and wear much faster than most, yet I do not get flats/punctures on them! They are surprisingly tough for a top end race tire. Bear in mind that I change out my rear the moment the center tread goes smooth, as I will not try to save a buck in favor of flats. I HATE FLATS!


Amazing ride quality!

  • Familiarity:I've used it several times

I'll make it short, because it has pretty much all been said.

If you want tubular-like ride quality without the hassle of tubulars (gluing, flats), pair them with Vittoria Latex tubes and "voil�". You will not believe that you are riding clinchers.

I run them on my ENVE 6.7 clinchers, which makes for a sublime ride. Now go and get some!


You have to try these

    I couldn't review these tires any better than Michael Nies and Noah Singer below... so I will just add a note about the history of our sport. Vittoria is a part of it.

    Vittoria is based in Northern Italy like many of the Big names of Italian cycling: Bianchi, Colnago, Pinarello, Campagnolo, Columbus tubing, Cinelli, 3T, Deda Elementi, etc. Vittoria has been manufacturing pro-level bicycle tires for 60 years. It shows. Their range and R&D is pretty amazing. For example, check out Vittoria's green "Pave EVO CG III" in both tubular or clincher for Winter use. They were designed specifically for puncture resistance and performance on the wet cobblestones of Paris-Roubaix (to dream) -or the wet chip & seal on your local roads in the Winter.

    Yes, Vittoria tires are made in Thailand (as are the also excellent Michelin Pro4 Service Course tires), but the company and design is based in Italy.

    These amazing 320 tpi "Open Corsa EVO CX" race tires feature fantastic traction, grip, and especially dynamic feel. The latter is what really sets these Vittorias apart for me. Great tires.

    Great tire though not made in Italy. Vittoria sold their original Italian shop to Veloflex who uses these old digs to still produce hand-made tires FROM Italy. Vittoria moved their production to Thailand as noted elsewhere. As an aside, I just weighed the hand-made Veloflex Corsa 23, it coming in at 199g. I weighed the Vittoria Open Corsa EVO CX II, it coming in at 225g. That being said, BOTH are excellent tires and the only two tires I ride now (Veloflex Master 22/23 on vintage, which is same tire as Corsa without the black dye on sidewalls). The only negative to the Veloflex is they are perhaps the hardest tire to install I've ever encountered. You must treat pre-stretch these tires if you have difficult wheels. I'm always amazed at how many people opt to ride tires that are so inferior in ride, handling, and rolling resistance, just to gain some extra wear. The difference is not subtle.

    Are these tires true-to-size? I'd like...

    Are these tires true-to-size? I'd like to go as wide as possible without frame rub.

    I've got Michelin Pro4 and the 23s measure 24.25 while the 25s measure 27.1 (which begin to rub the frame when out of the saddle).

    Best Answer

    In my experience the Vittorias run true to the claimed size, at least on my rims. They definitely run skinnier than Michelins for me.

    Can someone look on the box and tell me...

    Can someone look on the box and tell me if Vittoria Open Corsa EVO CX III are manufactured in Italy or China or Tawain. Thanks, Gianni


    Race Day Tire

      I strap these to my Zipp 202's on race day since it is a racing tire. In conjunction, I use the Vittoria latex tubes which will take the tire to the next level for super fast rolling and a comfy ride. I have not experienced any flats on race day so far. I have used the Conti 4000S, but in my opinion the open corsa are faster and corner very well. They fit my Zipp 202's really well and I am able to get them on in about 30 seconds using only my fingers. That is important because if I do flatten, it can get it changed super fast. Like I said, this is my race day tire, it may not be as durable mileage wise or offer bomb proof flat protection as say a training tire, it does serve it's purpose on race day and that's what I want. I run mine at 110/115.

      Hey Backcountry, aren't these actually...

      Hey Backcountry, aren't these actually clinchers? If so, why are they listed under tubulars?

      Hi Michael, these are indeed clincher tires. It sounds like there may be an issue with our search filters, perhaps due to the fact that these are also considered "open tubulars" using Vittoria's own vernacular for a clincher. If you have any other questions, feel free to shoot me a note directly at For more immediate assistance with product questions, you can also chat or call in to talk to one of our bike experts.


      Smooth Like a Fine, Italian Wine

      • Familiarity:I've put it through the wringer

      I rode on these until I manned up and got tubulars. These are the smoothest riding, best cornering, fastest wearing clincher tires I've used. They are ex pensive, but the performance is worth it. These suckers wear out fast, though. The typically lasted me about three months of riding in Southern California before needing replaced. If you want a better value, look at Rubinos or Diamantes. If you want to extract every bit of performance your bike has to offer, look no further.


      Smooth riding clinchers

      • Familiarity:I've put it through the wringer

      I liked the 25's on my Roubaix pro so much I bought the 23's for my Cervelo R3. Definite improvement in road feel on both. The smoothest riding clinchers money can buy, and on Chicago's crummy roads, you need all the cushion you can get!


      Only road tire I use

      • Familiarity:I've put it through the wringer

      I have a bike that can fit the 25c in front but only the 23c in back. Bummer since the 25c are the only way to go. I'm late to the party of 25c but they really are the best size tires. Roll just as good or better than 23c but with less pressure and therefore much more comfortable ride. They do wear quckly but with my 140lb's they last most of the summer. As with all rear tires it wears more quickly so get an extra for the rear as the front will last thru 2 rear tire changes. Although not advertised as wet condition tires I have ridden with then in downpours and they did just fine.


      Superb tires while they last

      • Familiarity:I've put it through the wringer

      I got a pair of these in 25c about three months ago, and found them to be great tires. I had read that some people have found them to have poor performance in wet conditions, but my experience is just the opposite: I've ridden them in the wet and dry and they have great grip either way. But as they say, the candle that burns twice as bright burns half as long. After about two months and 1000 miles, I'd worn out the rear tire completely, and I got a blowout as punishment for not checking more closely. The front is still in good condition. I'll order another Vittoria Open Corsa CX for the rear and put them back on next spring, but for the fall and winter I've switched to Continental Four Seasons. My initial impression of the Contis is that I like the Vittorias much better, but I want some extra puncture protection: I don't mind fixing flats so much when the weather is nice, but when it's cold and raining, that's a different story.


      There's a reason all the pros ride these

      • Familiarity:I've put it through the wringer

      The 320 TPI casing makes this supple and grip like a cat on carpet. These tires or PRO because they are ridden by all the PROs. If your bike accepts, go with the 25c width, if not, 23 will fit nearly everything.
