Vittoria Corsa G Road Tire. The Vittoria Corsa is already a legendary road tire, but with the advent of groundbreaking technology involving the revolutionary material Graphene the latest generation has upped the ante yet again. Behold the Vittoria Corsa G Road Tire. The Graphene in Vittoria's G Isotech tread compound is a nearly transparent sheet of pure carbon mere atoms thick. Prior to the development of Graphene, there was always the limitation of choosing between optimizing for speed, grip, durability and puncture protection. Effectively, the introduction of Graphene allows for natural material barriers of rubber to be removed, which means that there is no longer the need for such compromises between speed, grip, durability and puncture resistance. All these features now co exist in a single, Corsa G tire. Additionally, the Corsa G features Vittoria's 4 Compounds 4C technology which is a layering process that uses four separate compounds in the same tread. The 4C process offers unmatched versatility, by allowing for separate base and surface compounds in both the center and side areas of the tread. Benefiting from the different properties of each compound, including the G Isotech, their distribution has been extensively tested to deliver the best tire imaginable. There is also Vittoria's Corespun K casing that uses alternating Polycotton and Kevlar threads at an unbelievable 320 TPI, delivering incredible suppleness. The casing conforms closer to the road's surface, providing a smoother ride and better grip. All things considered, the Vittoria Corsa G is the top of the heap in the world of road tires.
