MY27 Fox 40 Factory 29" Fork - Grip X2

Fox MY27 Fox 40 Factory 29" with Grip X2 is a race-level suspension fork built for riders who demand maximum speed and control from a 29" downhill platform. With updated lower legs, a refined air spring, and a retuned damper, it targets better small-bump traction, more usable travel on long, rough descents, and more precise setup range for different tracks, tires, and rider styles.

Performance upgrades that matter on real trails

• Retuned Grip X2 damper - Independent high-speed and low-speed compression plus high-speed and low-speed rebound controls for accurate support under braking and G-outs, with the ability to free up traction without losing stability.
• GlideCore air spring - Vertically and horizontally compliant spring behavior helps the front wheel track through chatter; an MCU bottom-out bumper and increased negative volume improve comfort and control deeper in the stroke.
• Updated bleeders - Allows atmospheric pressure equalization for more consistent feel, more usable travel, and improved small-bump sensitivity as conditions and elevation change.
• Generative-designed lower legs - Refined arch shape and relocated internal bypass channels support smoother action under load and improved performance on sustained, high-speed rough sections.
• Factory Series Kashima stanchions - Kashima coating reduces friction for a smoother stroke and long-term durability where it counts: seals, bushings, and high-mileage park laps.
• Floating axle alignment - Precisely aligns the dropout surface to the front hub end caps to reduce unwanted friction between upper and lower legs, helping the fork move more freely through its travel.

Additional technical details for build compatibility

• Brake mount - Post mount, compatible with 180mm to 230mm rotors.
