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 line-up by combining high-end parts with a stout but light alloy frame, and 130 mm rear/140 mm front suspension for plenty of trail capability.
It's right for you if...
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.
The tech you get
An alloy frame, 140 mm FOX Rhythm 34 fork and 130 mm 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.
Why you'll love it
The final word
Fuel EX 8 gives you added efficiency with Shimano's latest, widest-range drive train and Trek's unique RE:aktiv damper that provides firm pedalling support without giving up any plush compliance.
