Designed to make you win The training tyre benchmark includes a strong nylon casing, secure grip, and long tread life. Using a mixed tread design, optimized for all-around use, the Zaffiro works well in a range of training conditions. Add the durable folding nylon casing, and you get a performance oriented training tyre at a great price! Technologies Graphene 2.0 With the aim to always push the boundaries of what is possible, Vittoria succeeded in the development of a new generation of Graphene: Graphene 2.0. Unlike the first-generation graphene, the new 2.0 graphene is functionalized to enhance specific tyre performances. In other words, where the first generation of graphene compounds raised the bar evenly, Graphene 2.0 pin-points each performance metric, and increases it disproportionally to the rest. Vittoria is now able to apply Graphene in such a way that it can achieve a performance boost specifically for speed, wet grip, durability and puncture resistance. Vittoria Clinchers Clincher is the most common type of tyre and it requires the use of tubes. It comes with a woven fabric casing, with either metal or folding fabric beads, and it is vulcanized during the production process. This irreversible process causes the rubber molecules to link together with a curing agent, notably carbon, to enhance the durability and strength of rubber itself.
