Overview
About this bike
Trek nailed the naming of this XC rocket, Superfly 8. Flying super fast is only half the story though; its handling and specs make it fully capable when the trail gets rowdy. Its aluminum chassis is equipped with G2 geometry and a 100mm Fox 32 Float up front to lead the way through sketchy sections as fast as possible. Sketchy or smooth, the specs are perfectly matched to this incredible frame and fork. You've got a 2x10 drivetrain with an XT Shadow Plus rear derailleur that makes chain slap and dropped chains a thing of the past. Tubeless-ready wheels, SLX discs and Bontrager Race Lite controls top everything off nicely. With speed, efficiency and fun, Superfly is the right name.
