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.
