Farley C is an OCLV Mountain Carbon fat bike frameset for four-season shredders who know fat bikes can be fast, high-performance machines — despite their oversized appearance. This insanely light fat bike frameset includes a Bontrager Haru carbon fork and is built to accommodate 26x5" or 27.5x4" wheels.
  • The faster you ride a fat bike, the more fun it gets — and this bike is a lot of fun.
  • Its a four-season freedom machine that lets you ride outside all year long.
  • You can run your choice of wheels with 26x5" or 27.5x4" tires
  • The lightweight carbon frame keeps the setup remarkably light and nimble for a fat bike

27.5˝ fat tires

More efficient 27.5" fat tires keep you rolling faster, especially on groomed or packed snow.
