OCLV Mountain Carbon
Treks mountain-specific carbon fiber is tougher carbon, with unique materials and layup procedures, Treks 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
Farleys 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 Farleys 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.
