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 rigid carbon fork, a SRAM GX Eagle 1x12 drivetrain with an extra-wide gear range, and Tubeless Ready carbon Bontrager Wampa wheels paired with 27.5x4.5˝ Bontrager Barbegazi TLR tires.

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. "

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.
