Fuel EX 8 is the ideal trail bike for mountain bikers who want a versatile full suspension ripper that can crush marathon and multi-stage races and still huck with the enduro crew. It hits the sweet spot of value and performance in our mountain bike line-up with an Alpha Aluminium frame, 140 mm front and 130 mm rear suspension, and a SRAM GX Eagle 12-speed drive train.
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 and aim to clear every rock garden on the first try. You want exceptional trail bike performance with the same MTB frame and suspension tech found on higher-end trail bikes, at an exceptional price.
The tech you get
A lightweight Alpha Platinum Aluminium frame, a 140 mm FOX Rhythm 34 fork and 130 mm of rear travel with a FOX Performance Float shock with Trek's exclusive RE:aktiv damper – it's enough suspension to go big while staying fast on the flats and climbs. A SRAM GX Eagle 1x12 drive train with a wide-range 10-50 cassette, Tubeless Ready Bontrager Line Comp 30 wheels, Shimano Deore hydraulic disc brakes, and a Bontrager Line dropper post for on-the-fly saddle height adjustments.
The final word
It's a trail bike that is fully capable keeping up with whatever you throw at it. It has the same frame and suspension tech found on our top-of-the-line trail bikes, with a SRAM GX Eagle 1x12 drive train that delivers a huge range of gearing with the simplicity of a single shifter.
