Tools Required
To install and adjust the Fox Float 40 29 Factory suspension fork, you will need the following tools:
- 5mm, 6mm, and 8mm Allen wrenches [paid link]
- Torque wrench [paid link] (for precise tightening)
- Suspension fluid (recommended by Fox)
- Fox shock pump (for air pressure adjustments)

Installation of the Float 40 29 Factory Fork
Installing the Fox Float 40 29 Factory fork requires attention to detail to ensure everything is properly aligned and torqued. Follow these steps for a smooth installation:
1. Preparing the Fork
Start by removing your existing fork. This can involve loosening the stem bolts and removing the handlebars. Be sure to retain the headset parts for reinstallation.
2. Installing the Fork
Slide the Fox Float 40 29 fork into the head tube, making sure it sits securely in the headset. Ensure the lower bearing is properly seated in the head tube. Tighten the crown race if needed, then slide the fork into place.
3. Attaching the Stem and Handlebars
Position the stem over the fork’s steerer tube, aligning it with the headset. Insert the stem bolts and tighten them evenly. Once the stem is attached, reattach the handlebars and adjust them to the desired position.
4. Securing the Wheel and Axle
Insert the front wheel into the fork dropouts. Secure the axle using the 15mm axle tool. Make sure the wheel is aligned properly before tightening the axle bolts. Check for any play or wobble after tightening.
5. Adjusting Air Pressure
Using a Fox shock pump, adjust the air pressure in the fork to suit your weight and riding style. The air pressure affects the sag and overall feel of the suspension.
6. Torqueing the Components
Using a torque wrench [paid link], make sure all bolts are tightened to the manufacturer’s recommended torque specifications. This is crucial for safety and fork performance.
Adjusting the Float 40 29 Factory Fork
Proper suspension fork adjustment is key to optimizing performance for different trail conditions. The Float 40 29 Factory fork offers multiple adjustment options for fine-tuning:
Air Spring Pressure
Adjust the air spring pressure based on your body weight and riding style. This affects the sag of the fork, which determines how much the fork compresses under load. Generally, a sag of around 25-30% is ideal for aggressive riding, ensuring the fork is neither too soft nor too firm.
Compression Damping
The Float 40 29 features the FIT 4 damper with three compression settings: Open, Medium, and Firm. These settings control how the fork responds to bumps and impacts:
- Open: Offers the most plush, sensitive ride. Ideal for technical, rocky terrain.
- Medium: Provides a balanced feel for mixed riding conditions.
- Firm: Reduces fork movement for smoother trails and flatter terrain.
Adjust the compression damping to match the trail conditions. Riders who frequently ride downhill may prefer a firmer setting, while those on rough, technical terrain may benefit from a more open setting.
Rebound Damping
Rebound damping controls the rate at which the fork returns to its extended position after compression. Adjust the rebound to prevent the fork from bouncing excessively or feeling too slow. A good starting point is to set the rebound to a mid-range setting, and then fine-tune based on trail feedback.
Maintenance of the Float 40 29 Factory Fork
Regular maintenance of your Fox Float 40 29 Factory fork ensures it performs at its best for a long time. Proper care can prevent wear and tear and maintain smooth operation.
Cleaning and Lubrication
After each ride, wipe down the stanchions with a clean rag to remove dirt and debris. If the stanchions become excessively dirty, use a specialized suspension cleaner. Regularly lubricate the seals and bushings with appropriate suspension oil to reduce friction.
Air Spring Maintenance
Check the air spring pressure at regular intervals, especially if you notice changes in performance or handling. Over time, the air seals may wear, leading to air loss. If this occurs, a complete air spring service may be needed.
Damper Service
The FIT 4 damper should be serviced every 100 hours of riding or annually, whichever comes first. This service involves draining and replacing the oil and checking for wear on the damper seals. Fox recommends professional servicing for damper-related issues.
Seals and Wipers
Inspect the fork’s seals and wipers regularly for signs of damage or excessive wear. Replacing the seals as needed will help maintain performance and prevent oil leakage.
Troubleshooting Common Issues
Even the best suspension forks can encounter issues. Below are some common problems with the Float 40 29 Factory fork and how to troubleshoot them:
1. Fork Sticking or Unresponsive Travel
- Possible Causes: Lack of lubrication, dirty seals, or improper air spring pressure.
- Solution: Clean the fork thoroughly, reapply lubrication to the seals, and check air spring pressure. If sticking persists, a full service may be required.
2. Bottoming Out or Not Enough Travel
- Possible Causes: Incorrect air pressure, compression settings too firm.
- Solution: Check and adjust the air pressure. If bottoming out occurs frequently, adjust the compression to a softer setting.
3. Fork Noises (Popping or Clicking)
- Possible Causes: Loose bolts, dirty or dry seals, or insufficient lubrication.
- Solution: Tighten all bolts to the recommended torque. Clean and lubricate the seals and check for any damage to the fork components.
Customization and Optimization
To get the most out of the Fox Float 40 29 Factory fork, you may want to further customize it for specific riding conditions. Here are some ways to optimize the performance:
Volume Spacers
Install volume spacers in the air spring to reduce the amount of air volume, giving the fork a firmer feel as it reaches the end of its travel. This is useful for riders who frequently bottom out on aggressive terrain.
Custom Tuning
Fox provides riders with the option to tune their suspension further using specific shim stacks or adjusting the damper internals. Custom tuning can improve responsiveness and control for specialized riding needs, such as downhill racing.
Compatibility with Other Drivetrain Components
The Float 40 29 Factory fork is compatible with a wide range of mountain bike drivetrains, including SRAM and Shimano systems. When pairing the fork with other components, ensure the following compatibility:
Headset Compatibility
The fork uses a 1.5” tapered steerer tube, which is compatible with most modern headsets. Verify that your headset matches the diameter and length requirements of the steerer tube.
Brake Compatibility
The Float 40 29 Factory fork supports post-mount disc brakes, so ensure your braking system is compatible with this mounting standard. The fork is designed for large rotors, typically in the range of 200mm to 220mm, which is standard for downhill and enduro applications.
By understanding the compatibility of the Float 40 29 Factory fork with other components, riders can optimize their bike’s overall performance.
