"Why pick anything else?"
"It's fast, handles trails like a boss, and the power transfer when pushing the cranks is nothing but impressive. It's a wonderful combination of smooth and snappy that thrives on the roughest-looking rubble. "

OCLV Mountain Carbon
Trek's mountain-specific carbon fibre is tougher carbon, with unique materials and lay-up procedures, Trek's advanced engineering, and a higher standard of testing.
27.5˝ fat tyres
More efficient 27.5" fat tyres keep you rolling faster, especially on groomed or packed snow.
Rapid Drive 108 rear hub
With 108 points of engagement, Rapid Drive gives you nearly instant acceleration instead of a clunky lag when you step on the pedals. You get smooth, immediate power to blast out of corners and hammer through the rough stuff. And that extra pedal ratchet adds control that can make all the difference when tackling a tricky climb.
Dropper post
Use the remote lever to lower your saddle so it's out of your way when you're descending and cornering.
Tubeless Ready wheels and tyres
Tubeless Ready rims and tyres make it easy to ditch the tubes so you get better traction, fewer flats and less weight. Just add TLR rim strips, valves and sealant.
Learn moreHorizontal Sliding Dropout
The horizontal sliding dropout with redundant securing mechanisms allows for no-slip single-speed or geared options and provides the ability to dial in the geometry to match each rider’s style.
Learn moreInternal cable routing
We route shift and brake cables through the frame to keep things clean and simple. And it looks great, too.
