Seriously improving small bump sensitivity in the Fox’s 40 Float FIT HSC/LSC FIT 27.5″ fork is the Float EVOL air spring, seen across Fox’s 2018 fork line-up. The 40 Float EVOL’s negative air spring chamber is larger for better small bump sensitivity, and increases the 40’s planted, plush, and seamless feel throughout it’s travel.
The FIT HSC/LSC damper is a completely sealed system, making the consistency and dependability that this system offers unbeatable. This year, they’ve continued using their famous bladder system as well for consistency. A dual circuit rebound path improves rebound characteristics, speed sensitivity, and helps the fork recover faster on deep stroke hits.
Friction will hinder even the best spring’s smoothness, and the 40 Float EVOL goes the distance to eliminate as much friction as possible, especially with the premium Kashima coating. One source of friction is pressure changing within the lowers?be it from ambient temperature or elevation change?causing the dust seals to bite into the stanchions. Pressure relief valves integrated into the lowers behind the arch reduce seal friction with the push of a button by bleeding air.
Fox’s 40 Float EVOL comes in a 27.5″/650b wheel size option, which has optimized lowers to maintain proper bike geometry and handling. Get shreddy and rad with the 2018 Fox 40.
