Technologies

3 mm rubber protection: Reinforced city tires use a durable nylon construction and a 3 mm-thick rubber layer between the tread and casing to help protect against punctures. Graphene compounds help extend the tire's service life and improve its performance on wet surfaces. The tire uses rigid beads, which are well tested and easy to use with inner tubes.

Nylon casing: Nylon is a strong, durable synthetic fiber traditionally used to make robust tire casings. Nylon threads are thicker than cotton threads, so there are fewer threads per inch. Nylon casings are strong and durable, which extends their wear life. However, as a synthetic fiber, nylon is not as elastic (soft and flexible) as cotton.

Graphene technology in tires: Vittoria uses graphene in tire compounds to improve tire performance. Graphene is the thinnest material in the world, while also being one of the strongest materials ever used in consumer products. It consists of a single layer of carbon atoms arranged in a hexagonal pattern. Graphene interacts with rubber by filling the spaces between rubber molecules. It acts like a magnet, bringing the molecules closer together and improving the overall structure of the rubber. The main properties of graphene are thinness, strength, flexibility, and light weight. In MTB tires, GRAPHENE 2.0 improves wet-surface grip across all product lines.
