New GRIPX2 Damper
To create the ultimate descent-focused damper, we sought the level of tunability seen in motocross and supercross racing suspension. Our award-winning Grip 2 damper had a 20 mm base valve diameter and seven valves. Grip X2 scaled up the tunability by increasing the base valve diameter to 24 mm with 23 valves. The result is the most tunable, supportive, and smoothest descent-focused fork damper ever created by FOX. Riders reap the benefits of sitting higher in the travel while tires stay glued to the ground. They can corner with increased traction, giving them the confidence to push the limits of downhill and enduro racing, all while reducing overall rider fatigue.

  • 23 Count Valve Stack for unprecedented tunability and quicker response to bumps.
  • Award-winning Grip 2 damper had a 20mm base valve diameter and seven valves. Grip X2 scaled up the tunability by increasing the base valve diameter to 24mm with 23 valves.
  • 24mm Base Valve lowers pressure to increase sensitivity and allows space for more damping circuitry.
  • Pressure Balancing maintains low positive pressure, allowing 5-10ms damper response time to rider inputs.
  • 4-Way Adjustability with high/low-speed compression and high/low-speed  rebound, now with less cross talk.

The Genuine Kashima Coat upper tube finish is slippery smooth and ultra-durable.

Floating Axle
Floating axles might look similar to other axles, but in fact they offer a distinct performance advantage due to their unique ability to match the exact width of the fork’s wheel mounting surface precisely to the front hub flange spacing, thus creating perfect chassis alignment and eliminating unwanted friction between the upper and lower fork legs. Floating axles provide much smoother suspension movement throughout the entire range of the fork’s travel, notably improving sensitivity and overall ride quality.

Lower Leg Channels
As a fork compresses, the air volume within the lower legs decreases, increasing air pressure. The more the fork compresses, the more pressure increases. This effect can have the unintended consequence of preventing full travel from being achieved. Fox's lower leg channels help alleviate this issue by dramatically increasing air volume within the lower legs and thereby reducing the amount of additional unintended pressure ramping.

Bleeders
The lower leg bleeders allow for atmospheric pressure equalization at the simple press of a button. Pressure build-up in the lower legs dramatically decreases fork performance, preventing full travel from being achieved, and diminishing small bump sensitivity and responsiveness.

Lower Leg Arch
Stiffness-to-weight is the ultimate metric for bicycle design. Engineers invest countless hours poring over every ounce of material in an effort to optimize this critical ratio. Fox's all-new lower leg design pulls out all the stops, shaving every possible gram while making sure not to compromise stiffness or strength requirements of modern enduro and gravity style riding.
