It's right for you if...

You don't like fat biking—you love it. You make the biggest investment in your fat bike because you have the best time riding it, and you're willing to shell out for the lightest, fastest, fat bike we make because you know there's a return in fun, speed, and adventure.

The tech you get

A lightweight OCLV Mountain Carbon frame with Stranglehold dropouts, a Bontrager Haru Pro rigid carbon fork with a carbon steerer, a SRAM GX Eagle 1x12 drivetrain with an extra-wide gear range, SRAM Guide RS hydraulic disc brakes, and Tubeless Ready Bontrager Wampa carbon wheels with a 108-tooth Rapid Drive rear hub for instant engagement paired with 27.5x4.5˝ Bontrager Barbegazi TLR tires. Plus, a Bontrager Line dropper post and a carbon handlebar.

The final word

It's the lightest fat bike we make. A carbon frame, carbon wheels, carbon fork, and top-shelf SRAM drivetrain come together in Farley 9.8 to make a high-performance ride that won't be slowed by foul weather, deep snow, or gnarly terrain.

favorite_borderWhy you'll love it

  1. This is a fat bike made without compromise: it's the lightest, fastest model we make
  2.  It's a four-season freedom machine that lets you ride outside all year long
  3. The 27.5x4.5˝ tires deliver more speed and traction than their 26˝ counterparts
  4. It's easy to set up tubeless—and when you do, you'll save weight and your ride will get even faster

"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.

Tubeless Ready wheels & tires

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.

Stranglehold dropout

Stranglehold dropout

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.

Sizing & fit

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 Trek retailer.
