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.
