The Vittoria Corsa G+ Tubular Road Bicycle Tire is the way to go when it comes to speed. By allowing for separate base and surface compounds in both the center and side areas of the tread, Vittoria's 4C compound offers unmatched versatility for all-road usability, maximum traction, and long-term treadwear. Graphene is a super-strong, super-resilient carbon structure created in sheets one atom thick. In this case, Graphene is made into a powder and dispersed into the rubber compound, adding wear resistance, puncture defense, and even structural strength, all without sacrificing tackiness for grip where needed. Even at a meager 270 grams, this tire flaunts a Kevlar reinforced Corespun K layer to aid in avoiding flats. This extra layer dramatically increases sidewall protection from punctures and ruptures. | Vittoria Corsa G Plus Tubular Road Bike Tire
