Technologies

4C compound

Road tires need to provide speed, handling and durability. “Vittoria 4C Graphene” compounds are designed to deliver grip on the road, low rolling resistance and a long service life. Two separate graphene compounds are used in the centre of the tread: one in the base and one on the surface. The base compound provides stability under acceleration and braking loads and helps protect against punctures and flats. The surface compound is designed to reduce rolling resistance while providing grip in both dry and wet conditions. Two separate graphene compounds are also used in the tread shoulders, one in the base and one on the surface. The base compound provides stability under cornering loads and helps protect against cuts in the tread. The surface compound is designed to provide grip when cornering in both dry and wet conditions. All four “Graphene 4C” compounds work together to reduce tearing and extend service life across varied terrain.

Tubeless TLR Road

The TLR construction provides puncture protection and speed. It uses a strong new “Zylon” material in the beads to retain air effectively. The tubeless setup is the lightest and fastest casing option. This is one of the reasons professionals choose CORSA.

Cotton casing

“Vittoria” was the first manufacturer of cotton tires. The brand’s top road tires are made from cotton, a lightweight material that makes the casing very flexible. Cotton threads have the finest structure used in tire casing technology; their advantages include low weight and flexibility. This allows more threads per inch in the casing: the highest-quality cotton casings reach 320 TPI. The tire can conform more closely to the road surface, resulting in a smoother ride, easier rolling and better grip. To increase the overall strength of the casing, “Vittoria” uses cotton threads of a type made from a blend of cotton and aramid fibres. “Vittoria” cotton casings are used in professional racing products, with victories in the “Tour de France”, “Giro d'Italia”, “Vuelta a España” and classic races, as well as world and European championships and the Olympic Games.

Graphene technology in tires

Graphene is a material that “Vittoria” uses in tire compounds to improve tire performance. It is the thinnest material in the world and one of the strongest materials used in consumer products. Graphene consists of a single layer of carbon atoms arranged in a hexagonal pattern. It interacts with rubber by filling the space between rubber molecules and acts like a magnet, drawing the molecules closer together and improving the overall rubber structure. Graphene’s main properties are thinness, strength, flexibility and lightness. In MTB tires, GRAPHENE 2.0 improves wet-surface grip across all product lines.
