Front knobs: arrow-like layout and side knobs for directional accuracy and straightaway visibility; V-shaped knobs improve braking stability and cornering side hold Grip and traction on a wide range of terrain (from mid soft to mid hard) Perfect application for training; optimal compromise between performance and durability Tread pattern taken from previous design with the rears layout rigidity improved through bridges Multi-ply carcass with high resistance to punctures but maximum flexibility to absorb forces during jumps or obstacles Training performance in all terrain conditions with uniform knob wear, resistance to deformation while damping and thus an extended durability Tube type Bias-Ply
