Trek Superfly FS 7 (2015)

Big wheels and a whole lot of speed -- that's the high-performance Superfly FS 7 from Trek. This sleek XC machine features a rugged, light alloy frame and a plush RockShox suspension system for control over the tough stuff. SRAM and Shimano components handle shifting, while Shimano hydraulic discs take care of braking. Parts from FSA and KMC round out the spec, and a Bontrager wheelset and tires complete the picture.
