TREX Mountain bikes Fuel EX 8 29
Fuel EX 8 is the ideal 29er trail bike for mountain bikers who want a versatile full suspension ripper that can climb with the XC crowd and huck with the enduro crew. It hits the sweet spot of value and performance in our mountain bike lineup with an Alpha Aluminum frame, 130mm front and rear suspension, and SRAM GX Eagle 12-speed drivetrain.
Color / Cardinal
A lightweight Alpha Platinum Aluminum frame, SRAM GX Eagle 1×12 drivetrain with a wide-range 10-50 cassette, Tubeless Ready Bontrager Line Comp 30 wheels with a 54-tooth Rapid Drive hub for quick engagement, and a Bontrager Line dropper post for on-the-fly saddle height adjustments. The 130mm front and rear FOX suspension with Trek’s exclusive RE:aktiv damper is enough to go big while staying fast on the flats and climbs.
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 1×12 drivetrain that delivers a huge range of gearing with the simplicity of a single shifter.
