Fox 40 Factory 29" Suspension Fork

The DH Racer's Advantage.
The winningest fork on the World Cup Downhill circuit, there is no substitute for the 40 when everything is on the line. Now with Glidecore air spring and revised GRIP X2 damper, it offers more tunability and traction than ever before.

“It gives you more grip and takes the edge of the bumps. Every square edge is rounded.” – Neko Mullaly, Frameworks Team Manager & Former World Cup Racer

Support Without Harshness
GRIP X2 is the most tunable, supportive and smoothest descent-focused damper designed to win World Cups. Sit higher in the travel, keep tires glued to the ground and corner with increased traction, all while reducing overall rider fatigue.

Built to Hold the Line
The generative designed arch maintains the 40’s steering responsiveness, while relocated bypass channels on the lowers contribute to even more smoothness and sensitivity at high speed. The 40 forgets the feature buzzwords and focuses on pure performance. 

Smooth Under Pressure.
The seamlessly compliant FLOAT Glidecore air spring reduces friction and bind by moving with the fork under dynamic load. Smoother suspension and reduced breakaway friction mean less fatigue in your hands and arms, so you can stay target locked on the podium.
