The Fox 36 Factory 29" Fork is the undisputed champion of all-mountain riding. Engineered with cutting-edge features to dominate descents, the 36 is the go-to choice for aggressive all-mountain enthusiasts. Available with either the trail-focused GRIP X or gravity-focused GRIP X2 damper options.
SMOOTHER, STIFFER, MORE GRIP
The 36 sets a new standard for all-mountain performance, delivering smoother suspension movement, increased stiffness, and enhanced grip on the trail. With unparalleled responsiveness and control, riders can push the limits with confidence.
GRIP X DAMPER
With the GRIP X damper, trail and all-mountain riders no longer have to compromise between descent-focused performance and lightweight endurance. The GRIP X damper offers exceptional descent performance with refined weight savings and easy setup, including an accessible firm mode for efficient pedaling.
GRIP X2 DAMPER
The GRIP X2 damper is the pinnacle of descent-focused damping technology. Offering exceptional tunability, support, and smoothness, it ensures riders remain higher in the travel while maintaining optimal traction for cornering. This damper instills confidence to push the limits of downhill and enduro racing while minimizing rider fatigue.
KABOLT X AXLE
Featuring a lightweight bolt-on floating axle design, the Kabolt X reduces weight while increasing torsional stiffness for improved handling. The innovative single-sided pinch bolt design enhances chassis alignment, minimizing friction between upper and lower fork legs for smoother suspension movement.
LOWER LEG BLEEDERS AND BYPASS CHANNELS
Equipped with bleeders for atmospheric pressure equalization and lower leg bypass channels to increase volume, the 36 delivers superior fork performance. These features enhance small bump sensitivity and responsiveness, ensuring optimal performance on every ride.
LOWER LEG ARCH
The lower leg architecture of the 36 prioritizes weight reduction without compromising stiffness or strength, meeting the demands of enduro and aggressive all-mountain riding. Built to withstand the rigors of challenging terrain, the 36 is ready to tackle any trail with confidence.
