Product technical specifications

TECHNOLOGY

4C COMPOUND: Road tires need to deliver speed, control and durability. Vittoria 4C Graphene compounds are specifically formulated to give ultimate grip with the lowest possible rolling resistance, while still providing a long useful wear life. The center tread area uses two separate Graphene compounds; one at the base, and one at the surface. The base compound provides a stable foundation for climbing and braking loads, while providing protection from pinch flats and punctures. The surface compound is formulated to provide minimal rolling resistance, while delivering ultimate traction in both wet and dry conditions. The shoulder area of the tread also uses two separate Graphene compounds; one at the base, and one at the surface. The base compound provides a stable foundation for cornering loads, while providing protection from slices in the tread. The surface compound is formulated to provide ultimate cornering confidence, in both wet and dry conditions. All four Graphene 4C compounds work together to minimize tearing and extend useful wear life, in a range of terrain.

Tubeless TLR ROAD: TLR construction offers ultimate puncture protection and speed. It uses a robust new bead material called Zylon for optimal air retention. Tubeless-ready set up is the lightest and fastest casing option. That's one of the reasons pros choose CORSA.

Cotton Casing: Vittoria is the first and still number one producer of cotton tires. As of today, only Vittoria best road tires are made out of cotton, a light material which makes the casing very flexible. Cotton threads have the thinnest structure in the tire casing technology, with benefits related to lightweight and flexibility. This characteristic allows to develop casings with a higher number of threads per inch, up to 320 TPI for the top-quality cotton casings. This property allows the tire to conform closer to the road’s surface, providing a smoother ride, easier rolling, and better grip. In order to boost the overall strength of the casing, Vittoria uses Cotton yarn, which is a particular type of yarn made by cotton and aramid fibres combined. Vittoria’s Cotton casing is used for Pro Competition products, proven by multiple victories as in Tour de France, Giro d’Italia, Vuelta a Espa?a, Classics, World Championships, European Championships and Olympic Games.

About GRAPHENE technology in tires: Graphene is the innovative material used by Vittoria in compounds to improve performance of tires. Graphene is the world’s thinnest material but at the same time one of the strongest ever used for consumer applications. Made of a single hexagonal-shape layer of carbon atoms, Graphene interacts with rubber by filling the space in between the rubber molecules. It acts like a magnet, making rubber molecules closer to one another and improving the overall rubber structure. Graphene’s main properties are related to: Thinness / Strength / Flexibility / Lightness.
