Fuel EX 9.9 makes no compromises. A carbon frame, carbon wheels, SRAM's X01 Eagle 1x12 drive train and FOX Factory Float suspension make this the one carbon full suspension mountain bike that rules every trail. It's fast on singletrack, light on climbs and stable through the rowdiest terrain you can find.

You know you'll be riding this bike on every trail, so you're not going to compromise on frame material, suspension or components.
The tech you get
A light and stiff full OCLV Mountain Carbon frame, 140 mm FOX Factory 36 Float fork with GRIP2 damper, 130 mm of rear travel with a FOX Factory Float shock featuring Trek's exclusive RE:aktiv with Thru Shaft and a 1x12 SRAM X01 Eagle drive train. Plus, powerful Shimano XT 4-piston hydraulic disc brakes, Tubeless Ready Bontrager Line Carbon 30 wheels with a 54-tooth Rapid Drive rear hub for quick engagement, a Bontrager Line Elite dropper post and a Bontrager Line Pro OCLV Carbon handlebar. An internal storage compartment and Control Freak cable routing add to the bike's capability and sleek look.
