When it's race day, it's time to get on the starting line, the race is on and all that matters is speed and performance, then S-Works is the way to go. The Fast Trak has over time become the benchmark for fast and light tires, capable of handling the most technical courses in the most demanding conditions. The tread pattern and knob shape have been carefully designed to allow it to roll fast with excellent traction, while the side knobs have been optimized to adapt to slippery surfaces with enough bite on loose ground. Lightweight and supple, our 120 TPI XC Race casing features minimalist flat protection (ply overlap), BUT you only need one acceleration to understand the S-Works magic and enjoy its incredible acceleration response and legendary low rolling resistance. Finally, it features our GRIPTON® compound, which maximizes grip, dampens vibrations, and offers incomparable traction in dry or wet conditions.
