TECHNOLOGY:

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.

4 Graphene-enhanced Compounds in One Tread - Because of their power, e-bikes need treads that do not wear out fast. Graphene improves the tread durability and rolling. This trait is very important as it positively affects the battery consumption, extending the battery life. The 4C technology, the layering process allowing to place 4 different layer of rubber compound in the same tread, improves the knobs strength and flexibility. Therefore, they can better resist to the strong accelerations of electric bike (they do not tear off because of the higher torque) without compromising the grip.

Robust Casing - Vittoria tyres for electric mtb use a 2-ply casing with sidewall protections for the best puncture protection and to protect the tyre from the weight and power of electric mountain bikes.

E-Bike Weight - The heavier weight of electric bikes is an issue for tyres indeed. Normally, tyres 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 tyres.Now try to imagine using a 22kg bicycle! Weight adds up stress to the tyre. Every obstacle becomes a weapon that can provoke a tyre failure. Therefore it is important to buy specific e-bike tyres that can handle all that weight without compromising riding safety and comfort.

E-Bike Speed - Speed is an important factor affecting the tyre consumption. The tyre knobs are stressed in acceleration, and every impact is much stronger when riding fast. E-bikes generate strong accelerations that may even tear off the tyre knobs. The higher torque of electric bikes requires compounds that can resist and fight back all that power.

Battery Saving Tyres - Vittoria e-bike tyres use durable graphene-enhanced compounds that reduce the rolling resistance and consequently extend the battery life.

Extreme Grip - Vittoria e-bike tyres guarantee non-stop traction when climbing and cornering, and they also allow shorter braking distances.

Puncture resistance - Vittoria fat tyres for e-bike use the most robust tyre construction ever developed from Vittoria. Each part of the tyre – casing, bead, tread, sidewalls – has been fine-tuned to improve puncture protection.
