Specialized Fast Trak Control Tyre

We've raised the bar on ourselves once again...redesigning the Fast Trak. Using not only rider feedback, experience, and knowledge, we've taken tread design a step further by manipulating each knob of the new Fast Trak with FE Analysis. The result is less rolling resistance, more traction when you need it, all in a lightweight package. Adaptive Tread technology for Competitive XC riders.
