The Fast Trak tire is synonymous with speed and lightness, capable of tackling the most technical trails and the most challenging conditions. The new Block-In-Block tread features a taller, more adaptable internal block that penetrates the terrain for perfect traction. The structure of the external block is larger and supports the internal block for greater speed, traction, stability, and handling. This tire's profile has been optimized for a wide range of rims with varying internal widths.
