Trek's Superfly 100 Pro is the epitome of speed, period. This full-carbon wonder sets the standard for race bikes everywhere with 100mm of travel and a hardtail's gossamer weight. Its Trek OCLV monocoque-carbon frame is super light and stiff and boasts all of Gary Fisher's proven geometry tweaks along with Trek's E2 head tube and ABP suspension technology for a ride that just shreds. Plus, a RockShox SID XX takes care of the front end with authority, and a custom, Kashima-coated Fox shock handles the rear end. Then add a full SRAM XX 2x10 parts group supplying power to tubeless-ready Bonty Race X Lite wheels and XX brakes, and the view from the front of the pack gets even better. The rest of the gear is just as good with Bontrager components including a carbon bar and post. The Superfly: proven on trails, feared at the races.
