The Lightest 36 Ever
The Fox Suspension 36 Float SL Factory is a sub-1800g fork that injects plushness and steering responsiveness into a true Trail fork. An evolution of the 36 chassis optimised for 120 to 140mm of travel, this fork gives modern Trail riders the confidence to go big without the weight. It supplants the 34 with 20% additional torsional stiffness while the updated chassis minimises the weight increase to just 100 grams. At 1755g (29” 140mm GRIP X), the 36 SL easily beats out its predecessor and the competition.
Arch and Chassis Design
Generatively designed and optimised by Fox engineers, the new 36 SL arch and crown increase torsional stiffness of the fork by a full 20% over the previous Trail fork, the 34. Cutouts and lightening bores at strategic locations help minimise weight.
Air Spring Compliance
The redesigned and compliant FLOAT air spring decouples the stanchion from the air shaft, allowing the piston to move with the fork while under bending loads, rather than resisting them. The result is smoother suspension action overall, especially when the fork is experiencing high loads from speed or rider weight. Additionally, the 36 SL has 20mm additional bushing overlap over the 34, which reduces friction between the stanchions and lower legs throughout the stroke.
GRIP X Performance
The GRIP X damper provides uncompromised all-mountain performance, offering the exemplary descent performance of GRIP X2, refined for less weight, easier set up, and an easy-access firm mode for pedalling efficiency. Inboard bypass channels help curb pressure ramping for increased small bump sensitivity and recirculate oil to lubricate bushings and seals. By relocating these channels to the inboard side, they are out of the fore-aft load path to further reduce friction.
Added Utility
- Low profile bleeders: A grooved design allows pressure to escape around your finger as you press the bleeder.
- Air spring top cap: Now uses the common Shimano cassette tool for easy volume adjustments.
- Mudguard: Mounts to seal flanges and arch instead of bleeder ports for a refined aesthetic, durability, and seal protection. Available in long and short styles.
