Technologies

3 mm rubber protection: Reinforced Vittoria city tires use a durable nylon construction and a 3 mm-thick rubber insert between the tread and casing to help protect against punctures. 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 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 service 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 and one of the strongest materials ever used in consumer products. It consists of a single layer of hexagonally arranged carbon atoms. Graphene interacts with rubber, filling the space between rubber molecules. It acts like a magnet, drawing the molecules closer together and improving the overall structure of the rubber. Graphene’s main properties are thinness, strength, flexibility and lightness. In MTB tires, GRAPHENE 2.0 improves wet-surface grip across all product lines.
