The winningest fork on the World Cup Downhill circuit. When everything is on the line, there is no substitute for the 40. Now with benefits of the Glidecore air spring and revised GRIP X2 damper, it offers more tunability and traction than ever before.
Grip X2
The most tunable, supportive and smoothest descent-focused damper ever created by FOX. Sit higher in the travel, keep tires glued to the ground and corner with increased traction, all while reducing overall rider fatigue. Learn more about the new GRIP family »
Bypass Channels & Bleeders
Bleeders allow tool-free pressure equalization and with the increased leg volume of bypass channels, help curb pressure ramping for increased small bump sensitivity. Channels also continuously recirculate oil, lubricating bushings and seals for a smoother ride feel.
FLOATING AXLE
The 20mm diameter floating thru axle allows perfect chassis alignment and reduces unwanted friction between the upper and lower fork legs, providing much smoother suspension movement throughout the entire 203mm of travel.
