The best-of-the-best, no-holds-barred, built for victory Superfly is here. The FS 9.9 SL uses a race-light yet trail tough OCLV carbon frame with a 100mm of travel along with Trek's proven technology: G2 geometry, carbon armor, internal cable routing, E2 head tube, carbon link, and ABP suspension. That all translates to bike that weighs less than most hardtails, climbs like a banshee, and slices singletrack like an L.A. surgeon. Nothing was spared to make you faster; you've got Kashima coated, remote controlled, Factory Series Fox suspension, full XTR shifting and braking and tubeless-ready RXL wheels with DT Swiss internals and through axles on both ends. A carbon bar, post, stem, and even carbon rails on your saddle make up the controls. The Superfly is speed personified.
