FOX 40 Factory

Overview

Target locked on the top step of the podium and developed in the crucible of World Cup competition, the 40 is the definitive DH race fork. The GRIP X2 damper now offers more tunability and traction than ever before, ensuring the 40 stays planted in the hot seat. With 203mm of travel and the race-proven FLOAT EVOL air spring, this dual-crown fork delivers unmatched performance for World Cup-level downhill racing. The floating thru-axle design reduces friction for smoother suspension movement, while lower leg bleeders and bypass channels enhance small bump sensitivity and responsiveness.
