This model redefines what was thought possible with a cross-country tread design. Specialized's 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. The Control casing is Specialized's light and durable do it all XC construction. To top off this build they use their fastest rolling, race ready T5 compound with excellent wear and tear protection.
