TECHNOLOGY

4C COMPOUND: XC tires need to deliver speed, control and durability. Vittoria 4C Graphene compounds are UCI XC World Championship proven, and 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.

XC Trail Casing (Tubeless TNT) XC-Trail is the most robust Cross Country casing option from Vittoria. Designed for the most demanding XC courses, the Xc-Trail casing use an additional 120 TPI Nylon layer on the tire sidewall to prevent cuts and punctures. The tubeless-ready construction allows for resistance and strength without impacting too much on weight.

TNT (Tubes No Tubes): Tubeless TLR tire with reinforced sidewalls. Tire can be safely used with both tubeless and traditional inner tube setups. It enhances durability and cut resistance, also offering Vittoria's legendary supple ride quality. TNT tire features two nylon layers placed on both sidewalls. These layers are crucial in protecting the tire casing from punctures and cuts caused by rocks and thorns.

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. Considering MTB tires, GRAPHENE 2.0 improves wet grip in all product lines.

Nylon Casing: Nylon is a robust and durable artificial fiber traditionally used for strong tire casings. Nylon threads are less thin than cotton ones, so casings have a lower number of threads per inch. The advantages of nylon casings is that they are strong and durable, extending the wear life of the casing. However, because it is an artificial fiber, it is not as supple (soft/flexible) as cotton.
