The tech you get
A lightweight OCLV Mountain Carbon frame with horizontal sliding dropouts, a Bontrager Haru rigid carbon fork, a wide-range SRAM GX Eagle drivetrain with an extra low climbing gear, a dropper post for getting down, and SUNringlé Mulefüt wheels paired with a 108T Rapid Drive hub for instant engagement, and wide, ultra-grippy Bontrager Barbegazi TLR tires.
The final word
Speed in every season. Farley 9.6 is light, fast, and built to rip. It's the ideal winter shred sled for fat bike adventurers, racers looking to train outside year-round, and anyone who values the performance advantage of carbon.
favorite_borderWhy you'll love it
- A lightweight carbon frame and fork mean this bike won't be bogged down by foul weather, deep snow, or gnarly terrain
- The stability and traction of super wide tires make you a more confident rider on any trail
- Horizontal sliding dropouts lets you fine-tune your geometry—run it long for stability, or shorter for more nimbler handling
- The dropper post lets you lower your saddle on the fly so it's out of the way on descents
- It's a four-season freedom machine that lets you ride outside all year long
"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. "

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.

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.

Sizing & Tech
The charts below show our recommended sizes based on height, but there are some other factors, like arm and leg length, that determine a great fit. That’s why you’ll see some overlap in our recommendations. Not every rider who’s 5´8˝, for example, will fit on the same size bike. The best way to find your perfect fit is to consult the experts at your local retailer.
