FAQs

What is the travel of this fork?

The FOX 40 Factory GRIP X2 Fork offers 203mm of travel.

What is the maximum rotor size supported?

This fork supports a maximum brake rotor size of 230mm.

How do I adjust the air pressure?

Air pressure can be adjusted using a standard shock pump on the air valve located under the top cap. The top cap itself uses a splined interface for easier removal/installation with a cassette tool.

What is the axle standard?

It uses a DH Boost 20mm floating axle system.

What is the benefit of the GlideCore air spring?

The GlideCore air spring adds vertical and horizontal compliance, which helps the fork stay aligned with uneven terrain, improves tracking, and reduces binding for better grip and a smoother ride.

Is this fork suitable for trail riding?

This fork is specifically designed for elite gravity and downhill riding. Its long travel and robust construction make it less suitable for general trail riding.

How often should I perform lower leg maintenance?

It is recommended to perform lower leg maintenance, including cleaning and re-lubricating seals, after significant use or exposure to wet and muddy conditions. Refer to the FOX service manual for detailed instructions and recommended intervals.

Troubleshooting

Fork feels harsh or bottoms out unexpectedly.

Check air pressure; it may be too low. Adjust rebound damping. Ensure the MCU bottom-out bumper is correctly seated. Consult the tuning guide for appropriate settings for your weight and riding style.

Fork feels

Check that the through-axle is properly tightened and the wheel is seated correctly. Ensure brake calipers are not rubbing. If the issue persists, check for any binding in the fork lowers.

Stanchions are dirty or have debris on them.

Clean stanchions immediately with a soft, damp cloth. Avoid abrasive materials. For deeper cleaning, refer to the FOX service manual for lower leg maintenance.

Damping feels inconsistent.

Use the updated bleeders to release any built-up air pressure in the lower legs. Ensure the fork has undergone regular lower leg service as per the manufacturer's recommendations.

Pros and Cons

Pros

  • Exceptional downhill performance for aggressive riding.
  • Advanced damping and air spring offer superior control and traction.
  • Improved chassis stiffness for precise line holding.
  • Reduced rider fatigue due to enhanced compliance and smoother travel.
  • Easier setup and maintenance with updated bleeders and tool-compatible top cap.

Cons

  • Advanced features may require a learning curve for optimal tuning.
  • Higher price point typical of flagship suspension components.
  • Primarily designed for downhill and gravity riding, may be overkill for other disciplines.

Setup, Compatibility & Care

Setup: The air-side top cap features a splined interface compatible with standard cassette tools, simplifying air pressure adjustments. Consult the FOX suspension tuning guide for detailed recommendations on air pressure, rebound, and compression settings based on rider weight and terrain.

Compatibility: This fork is designed for DH Boost (20mm Thru-Axle) front hubs with a 110mm spacing. It accommodates a 1.125" steerer tube and is compatible with brake rotors up to 230mm. The maximum tire size it can fit is 2.5 inches.

Care: Regularly clean the fork stanchions and seals with a soft, damp cloth to remove dirt and debris. After significant use or exposure to wet conditions, consider performing lower leg service as outlined in the FOX service manual, which includes cleaning and re-lubricating seals. Ensure pressure bleeders are used periodically, especially after long descents, to release any built-up pressure in the lower legs.
