Martello hammers home the performance you expect, on the most demanding Enduro and DH courses. Looking for the one tire to tackle a wide range of courses? This is the ticket. How does the Martello deliver this level of performance? Start with a World Championship proven TNT bead, add the proprietary 4C Graphene compound, and top it off with a moto-inspired tread design with progressive width siping. This last part is key, and provides for a progressive feel on the effective edge, allowing for that fine-touch tactile feel that top racers expect. Additionally, 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. Whether shredding rocks, roots, or mixed terrain, Martello delivers!
