TECHNOLOGY

E-BIKE Specific Tire:The heavier weight of electric bikes is an issue for tires indeed. Normally, tires are the part of the bike that is more prone to damage, as it is the only point of contact with the ground. Rocks, roots, debris… all obstacles you can find on the trail can be harmful to your tires. Now try to imagine using a 22kg bicycle! Weight adds up stress to the tyre. Every obstacle becomes a weapon that can provoke a tire failure. Therefore it is important to buy specific e-bike tires that can handle all that weight without compromising riding safety and comfort. Vittoria e-bike tires use durable graphene-enhanced compounds that reduce the rolling resistance and consequently extend the battery life.

3 mm Rubber protection:Vittoria reinforced city tires use a robust and dependable nylon construction and a 3 millimetres-thick rubber braker placed between the tread and the casing for increased puncture protection. They feature Graphene compounds, offering increased useful life and wet weather performance. Rigid beads are used, as they are long proven, and provide ease of use with inner-tubes.

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.

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.
