Trek's Superfly: proven on trails, feared at the races. The 100 Pro SL's OCLV carbon frame is incredibly light and stiff, resulting in a complete bike that weighs less than most hardtails. All of Trek's stellar mountain bike technology is here: G2 geometry, carbon armor, internal cable routing, plus Trek's E2 tapered head tube, Flow Mold carbon link and ABP rear suspension. All this means Trek thought of everything to create a bike that just shreds. They also spec'd it accordingly. A RockShox SID World Cup takes care of the front end, 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 SRAM XX brakes putting the clamps on, 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 top tier stem, seatpost, and carbon bar.
