The 2014 Trek Men's Superfly FS 8 29er Mountain Bike is the ultimate 29er full suspension race bike. You get speed, speed, and more speed, plus incredible handling and control. This is a dedicated XC rocket ship for flat-out XC racing. Trek's patented ABP (Active Braking Pivot) keeps your suspension from stiffening up when you're on the brakes, giving you confident, steady control. Advanced frame geometry and a custom offset fork give you precise handling at low speed without compromising high-speed stability. The FS borrows features from the high-end SL for a fast, light, great-handling ride without blowing the budget.
