Technologies

Graphene technology in tires

Vittoria uses graphene in tire compounds to improve their 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 the rubber, filling the spaces between rubber molecules. Acting like a magnet, it brings the molecules closer together and improves the overall structure of the rubber. Graphene's key properties are thinness, strength, flexibility and lightness. In mountain bike tires, Graphene 2.0 improves grip on wet surfaces across all product lines.

Four graphene-enhanced compounds in one tread

The power of electric bikes calls for tread that does not wear out quickly. Graphene improves tread durability and rolling performance. This is important because reduced rolling resistance helps save battery energy and extends battery life. 4C technology is a layering process that places 4 different rubber compound layers in the same tread. It improves the strength and flexibility of the rubber tread knobs. As a result, they better withstand strong e-bike acceleration and do not tear under higher torque, while maintaining grip on the road surface.

Durable casing

Vittoria tires designed for electric mountain bikes use a dual-layer casing with sidewall protection. It is designed to provide puncture protection and help the tire withstand the weight and power of electric mountain bikes.

E-bike weight

The greater weight of electric bikes presents additional challenges for tires. Tires are often one of the more vulnerable parts of a bike because they are its only point of contact with the ground. Rocks, roots and debris on the trail can damage tires. Now imagine riding a 22 kg bike: the extra weight increases the load on the tire, and every obstacle can cause tire failure. That is why it is important to choose tires designed for e-bikes that can withstand this weight without compromising riding safety and comfort.

E-bike speed

Speed affects tire wear. During acceleration, the tread knobs are put under stress, and at high speed every impact is stronger. E-bikes accelerate powerfully, which can even tear off the tread knobs. The higher torque of e-bikes calls for compounds that can withstand this power.

Battery-saving tires

Vittoria e-bike tires use durable graphene compounds that reduce rolling resistance and thereby help extend battery life.

High grip

Vittoria e-bike tires provide continuous grip on climbs and through turns, and also help shorten braking distances.

Puncture resistance

The construction of Vittoria's thick tires for e-bikes uses the strongest tire construction the brand has developed to date. Every part of the tire—the casing, tread and sidewalls—has been improved to enhance puncture protection.
