The Vittoria Corsa is one of the most popular and best performing tires of all time. Vittoria pioneered the "open tubular" concept which gave the incredible road feel of a tubular to the convenient clincher tire format. The super high threadcount (TPI) tires had a soft, supple ride and incredible cornering abilities that were virtually unmatched by any other clincher out there. One knock against them from some quarters though was longevity. So that's why Vittoria has completely redesigned the tire to be the most advanced, and hardest-wearing race day tire ever.
