Green with envy.
Whether it be Roubaix or Flanders, you've surely seen the Open Pave CG's characteristic green stripe pass over the finish line in top position. And while we've yet to see clinchers break the tubular's stranglehold on the cobbled classics, we have seen race-day carbon clinchers make an unprecedented rise. Accordingly, with the Vittoria Open Pave EVO CG III tire, you're able to apply Vittoria's strongest available grip to any road that warrants a touch of added confidence.
If you're unfamiliar with how the Italians operate, we'll break down the title for you. 'Open' is the Italian terminology for clincher, as in the clincher-version of Vittoria's Pave CG tubular tire. Meanwhile, 'Pave' translates to 'cobblestone,' as in, this is a tire that's designated for rough roads. Put the two together, and add in the evolution designation of 'EVO,' and you have a next-generation tire that's designed for speed. And while we understand that a name is simply a name, the Open Corsa line's results speak for themselves. Simply put, this line boasts more race wins than any other tire in history.
And now that we have your attention, let's dig into the CG's construction. Vittoria gave this tire a 320TPI casing composition, meaning that the sidewalls consist of 320 threads per inch. And if you're wondering why there are 'threads,' this is because the EVO CG 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 CG. By this, we mean that the tire's weight hovers around 240 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. And for the Pave CG, Vittoria incorporated its grippiest tread pattern to date. So, whether you're actually racing cobbles, or simply wet chip-and-seal roads, the Pave CG will provide a reliable traction with the surface beneath you.
