34 Float SC 27.5 FIT4 Factory Boost Fork

FOX introduced its 32 Step-Cast Fork a few seasons ago as a cross-country weapon that shaved every last gram for efficiency. While it did lose a touch of stiffness and tire clearance, rail-thin XC pilots rarely run anything wider then 2.1-inch tires and simply clamored to the 100-millimeter travel fork and its svelte 32-millimeter stanchions. FOX realized that trail riders and marathon cross-country racers were after a bit more travel yet still wanted a lightweight fork, so it now offers the 34 Float Step-Cast Fork to drop grams from the traditional 34 Float while maintaining stiffness and rigidity.

  • Ultra-lightweight trail fork with cross-country efficiency
  • Designed for technical XC races and epic trail rides
  • 34 Step-Cast design with 120mm of travel and a Kabolt 110 bolt-on axle
  • Stepped, hollowed-out lowers significantly reduce its weight
  • Stiffness is similar to what you'd find in a 140mm Float 34
  • Float air spring with EVOL offers better small-bump compliance
  • Fit 4 damper with 3-position adjust: Open, Medium, Firm modes
  • Item #FRSC05H
