Technologies

3 mm rubber protection

Reinforced Vittoria city tires use a reliable nylon construction and a 3 mm-thick rubber layer between the tread and casing to increase puncture protection. Graphene compounds help extend tire life and improve performance in wet conditions. The tires use rigid beads, which are well-tested and easy to use with inner tubes.

Nylon casing

Nylon is a strong, durable synthetic fibre 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 fibre, nylon is not as elastic (soft or 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 and 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, drawing the rubber molecules closer together and improving the overall structure of the rubber. Graphene’s key properties are thinness, strength, flexibility and lightness. In MTB tires, GRAPHENE 2.0 improves wet grip across all product lines.
