Martello Race uses Vittoria brand new Graphene & Silica soft compound specifically developed to satisfy the needs of performance oriented gravity riders seeking ultimate grip on any trail and condition. This softer compund provides optimal flexibility and deformation to the tread. Grip and damping absorption are maximized at every lean angle enhancing traction and control even on the toughest sections. 'Speed by more grip' will lead your riding performance with no compromises. Martello Race also features a new 60 TPI, reinforced nylon casing with extra puncture-resistance layer placed at the center, between the tread and the casing, that offers increased robustness to the tyre. Martello Race uses the same proven tread of the Martello you are familiar with. Its motocross-inspired squared knobs with directional sipes provides grip and rolling efficiency. The Martello tread design offers exceptional performance on a wide range of rocky and hardpack terrains. The progressive sipe width in center and side tread allows for tactile feeling at the knob surfaces.
