About this bike
Roll right through gnar, or air over it. Either way, Trek's Session 88 DH 27.5 gets you to the bottom in the fastest time possible. This world-class downhill rig takes Trek's great aluminum frame and adds a Boxxer up front with 200mm of some of the smoothest travel out there. In back, Fox is in control with a sweet DHX coil delivering 210mm of madness with Trek's Full Floater and ABP suspension designs which isolate suspension action from braking input. Add DT Swiss tubeless-ready wheels with a massive 12x157mm rear axle, SRAM gearing and the 88's DH race geometry and you realize that if you roll right through gnar, or air over it, the Session gets you to the bottom fast.
