Vittoria is always moving forward. Breaking boundaries and setting ever higher standards is how Vittoria develops new production processes. Constant research and development allow Vittoria to deliver the performance that riders expect from Vittoria.
This approach is most evident in the new range of Vittoria 4C mountain bike tires. No other tire maker has the know-how and resources to produce a single tire combining up to 4 compound layers. Vittoria is the #1 company in the world using 4 compounds in a single tire tread. The company invested millions of dollars in the only extruder in the world able to mix 4 compounds in a single tread: an impressive high-tech machine which is a true miracle of engineering.
This is Vittoria 4C technology.
The reason for 4C came from the compromise of traditional single-compound bicycle tires. Tires with harder compound last longer, but at the expense of having less grip. Likewise, softer tires grip well but roll slower, and often show pre-mature wear. The traditional 1-compound approach has obvious limitations.
The solution to this problem came in the form of 4C, when Vittoria became the #1 brand to engineer a single tire using 4 separate compounds.
Vittoria 4C compound layering technology features separate base and surface compounds, in both the center and the side areas of the tread. This approach allows to fine-tune the flex of the tread-base and tread-surface separately, placing the correct hardness of the Graphene 2.0 compound exactly where it is needed for maximum cornering, climbing, rolling, and braking performance. In addition, durability and puncture protection are also improved, as the robust base compound resists punctures, and provides a stable base for deeper mountain bike treads.
Each of the 4 layers is comprised of different natural and synthetic rubber types, blended into the compound that works best for the intended use. This allows for endless customizations of each layer according to the tire needs.
