About this bike
Trek's carbon Session 9.9 DH 27.5's sole focus is World Cup downhill domination. Period. This sleek gravity sled gets it done with 210mm of rear travel while weighing in around 35 pounds. Trek achieved a massive stiffness-to-weight ratio through the use of advanced carbon lay-ups and trussing. That formidable stiffness is enhanced by their 157x12mm rear through-axle, carbon EVO link, and of course, the Full Floater linkage and ABP rear end. For the fork, Fox delivers their dominating 40 FIT RC2 that's highly adjustable so you can tune it to your style or the course. Out back, Fox's DHX 2 SLS coil absorbs hits of all sizes. With race-dialed components like Saint gearing and brakes along with custom DT Swiss wheels wrapped in Bonty Team tires, its focus on the hot seat is crystal clear.
