Specialized Fast Trak Sport

" The Fast Trak Sport has become synonymous with fast and lightweight tires that are able to handle the most technical courses and the most grueling conditions. This model redefines what was thought possible with a cross-country tread design. Our Block-In-Block design uses a taller adaptable inner block to pierce the ground and claw for traction. The larger outer structure supports the inner block for additional speed, traction, support and stable handling. Adding to this, the Fast Trak profile and knob spacing has been optimized for a wide variety of internal rim widths. Fast Trak Sport"
