Vittoria Corsa EVO CX III - Tubular Tire $109.95
Your bike's shoes for race day.
Vittoria overhauled its best-selling Pro Series tire in the form of the new Corsa EVO CX III Tubular Tire. And while our personal experiences on the road -- combined with our customers' feedback -- proved that the original EVO CX was at the top of its class, Vittoria knew it could improve on this exceptional tire's design. The result is the latest chapter in Vittoria's Corsa EVO lineup -- that humble collection of racing tires holding more race wins than any other tire in history.
Vittoria gave this tire a 320TPI casing composition, meaning that the sidewalls are comprised of 320 threads per inch. And if you're wondering why there are 'threads,' this is because the EVO CX is a cotton tire. But, don't think that this decreases durability. In fact, Vittoria used a corespun, or 'polycore,' technique for the casing's construction. Essentially, this means that the casing fibers are made by twisting staple cotton fibers around a central filament core, creating one yarn from multiple fibers. As a result, the material is between 40 and 50% stronger than typically spun materials, while retaining a similar, if not lower, overall weight. Additionally, the 320TPI cotton casing provides the ideal stiffness-to-weight ratio for the CX. By this, we mean that the tire's weight hovers around 250 grams, depending on width, while still retaining a perfect level of flexibility for cornering.
Along these lines, you'll notice that the casing's high TPI equates to finer-grade fibers used in its composition. Accordingly, the fine fibers are more malleable than say, 220TPI casings, and this flexibility creates a more adaptable interface for the tire's rubber contact surface during cornering. So, this design provides a higher level of grip than rubber, which is why cotton casings are used on nearly every high-end tubular in the world. Additionally, the weave's density also absorbs a great deal of impact, while also contributing to a low-level of rolling resistance. This equates directly to both comfort and speed.
For this generation of the EVO, the tire receives Vittoria's newest rubber compound, ISOgrip. After two years in development, Vittoria is confident that it's set the benchmark for racing rubber. According to Vittoria, ISOgrip expresses equal grip in both dry and wet conditions and features its lowest rolling resistance to date. However, like any racing tire, these benefits arrive at the cost of a relatively low wear-resistance, but on race day, you're not going to be worried about wear.
The Vittoria Corsa EVO CX III Tubular Tire is available individually in either a 23 or 25mm width. Additionally, it is available in a tubular form and in the color Black.

Nice, smooth and fast!!

I am fairly new to tubulars but see no need to search for anything but the Vittoria Corsa Exo CX tires. This is my third set but the first set to have glued myself. I had a failed attempt with some Conti GP4000s (so tight that one was ruined in the mounting process). Do your homework if you are installing yourself! Mounting is a process and takes attention to detail and patience. BIG thanks to Comp Cyclist rep Adam DeWitt (ext 5630) for his advice and expertise on the mounting process!!
Tubulars, in general, deliver a much smoother, more compliant ride and also a light lighter...but if you are the fence between clinchers and tubulars, tubs will only win if you are willing to take the time to install OR are willing to pay (& trust) someone to install for you. I have run both the 23s and 25s and appreciate them both for what they are...23s are a little racier and 25s are a little more comfortable.
The GOOD: smooth, supple and fast! Can't beat 320TPI!!
Easy to install (Contis almost broke my thumb but Vittorias slide on like butter!)
Durable! I have been able to get minimum of 2000 miles on a set but probably could have squeezed a little more (I do run a small amount of sealant for insurance on flats).
The NOT SO GOOD: they are a little expensive but worth the price.
You could ask for them to be more durable but that may come at the cost of the comfort.
Bottom line: get these tires and you won't be disappointed!

As the title suggests, these are some fine riding tires. The wear life on them is not the best, but they lasted me a season of racing without issue. These were on race day only wheels, and I never raced in the rain (one of the perks of living in SoCal), so I can't comment on handling, but the Open Corsas did very well while I lived in Cleveland and DID race in the rain. I suspect these will perform very similarly. Glue 'em up and go win something!
