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 single-track 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 exceptional value. 

The tech you get

A lightweight Alpha Platinum Aluminium frame, SRAM GX Eagle 1x12 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 dropper post for on-the-fly saddle height adjustments. The 130 mm 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 at 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 drivetrain that delivers a huge range of gearing with the simplicity of a single gear lever.
