Vittoria is the world's leading manufacturer of cotton tire casings, which are produced in their own factories. Put simply, the finer the cotton fabric, the more supple the tire casing. The casing conforms closer to road's surface, giving a smoother ride, easierrolling, and better grip. The grade of fabric used in a tire's casing is expressed in threads-per-inch (TPI): the higher the TPI number, the finer the threads, the denser the weave, and the suppler the tire. Uniquely, Vittoria makes casings with 320 TPI cotton yarn--the finest available. This is thefabric that goes in to the legendary Pro Series, proven by millions of kilometers of racing.
