Details

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 lineup with an Alpha Aluminum frame, 140mm front and 130mm rear suspension, and SRAM GX Eagle 12-speed drivetrain.

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 value.

The tech you get
A lightweight Alpha Platinum Aluminum frame, a 140mm FOX Rhythm 34 fork and 130mm 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 drivetrain 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 of 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 drivetrain that delivers a huge range of gearing with the simplicity of a single shifter.

Why you'll love it
- This bike is perfect for shredding singletrack, hitting drops, and pushing your limits in multi-stage and marathon events
- If you measure quality in performance per dollar, you won't do better than Fuel EX 8
- You sense its capability immediately, like when you're charging through sections of trail you never thought you'd clean
- The shifter-style, underbar remote dropper post lever is super intuitive and easy to use
- We expanded our size range to ensure a better fit for all riders. And, you get the fastest wheel that fits your frame: XS frames get 27.5-inch wheels, S frames get to choose between 27.5-inch or 29-inch, and sizes M to XL get 29-inch wheels

Smaller frames (XS and S) have a top tube that dips down as it approaches the seat tube. This design makes for a lower standover height, which is good for shorter riders because it allows them to straddle their bike more easily. Larger frames (M and up) have a straight top tube because taller riders with longer legs typically don’t have the same issues with standover height.

A dropper seatpost allows you to quickly lower and raise your seat to give you an ideal riding position. Dropping your seat creates a lower center of gravity for better control and maneuverability on steep descents, while raising it puts you at normal riding height for efficient pedaling.

Construction can include either hydraulic- or cable-actuated systems and the post’s travel can either be infinitely adjustable or stopped at set intervals, depending on the model.

Dropper seatposts come in standard lengths and diameters and vary by the amount of travel.
