"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 fiber is tougher carbon, with unique materials and layup procedures, Trek's advanced engineering, and a higher standard of testing.
Fat and fast
27.5″ fat tires give you the best combo of all-terrain grip, stability, flotation, and fast-rolling speed
Adventure-ready fork
Farley's new, short-offset OCLV carbon fork puts you in an optimal position over the front wheel, upping traction over sketchy terrain while allowing for a shorter stem. A custom rack mount on the crown and thoughtfully positioned triple bottle bosses (64mm spacing) on the lower legs let you gear up without sacrificing handling. Protective rubber bumpers on the bottom of the fork legs keep Farley upright and manageable when the front wheel needs to come off.
Haul of the wild
Mounts all over the frame let you carry a wide variety of gear with endless customization options. Gummy bears? Extra layers? Camping gear? Haul it all.
Keep it clean
Internal routing helps to protect Farley's components from the elements and makes it easy to mount gear
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.
Upgrade your pedals and love your bike more
Pedals are two of the five touchpoints that connect you with your bike, and even though this bike comes with a pair, upgrading to pedals that boost control and grip will greatly improve your ride. See the pedal guide and find the best pedals for your riding style. We recommend flat pedals for simple versatility.

Use the remote lever to lower your saddle so it's out of your way when you're descending and cornering.
Tubeless Ready wheels & tires
Tubeless Ready rims and tires 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.

Horizontal sliding dropout with redundant securing mechanisms allows for no-slip singlespeed or geared options and provides the ability to dial in the geometry to match each rider’s style.

We route shift and brake cables through the frame to keep things clean and simple. And it looks great, too.
