Fuel EX 8 is the ideal trail bike for riders who want a versatile full suspension ripper that makes soul-crushing climbs less painful, but can also huck rowdy trails.
Fuel EX 8 is the ideal trail bike for riders who want a versatile full suspension ripper that makes soul-crushing climbs less painful, but can also huck rowdy trails. It hits the sweet spot of value and performance in our mountain bike lineup by combining high-end parts with a stout but light alloy frame.
You're cool with your wheels leaving the ground, but you also like to go the distance on marathon singletrack sessions. You want a bike that lets you crush any trail, and your priority is on the parts.
An alloy frame, 140mm FOX Rhythm 34 fork, and 130mm of rear travel with an extra-efficient RE:aktiv damper. A Shimano XT 1x12 drivetrain with an extra-low 51-tooth climbing gear, powerful 4-piston brakes, Bontrager wheels with a 54-tooth Rapid Drive hub for fast engagement plus a Bontrager Line dropper post.
Fuel EX 8 gives you added efficiency with Shimano's latest, widest-range drivetrain and Trek's unique RE:aktiv damper that provides firm pedaling support without giving up any plush compliance.
