Tools Required

• Fox Float 38 Factory Orange suspension fork
• 5mm and 6mm hex wrenches
• Torque wrench [paid link]
• Suspension fluid (recommended by Fox)
• Fox air pump (specific to the fork)
• Grease (appropriate for bike parts)
• Clean rags
• Isopropyl alcohol (for cleaning)

Installation of the Fox Float 38 Factory Orange Fork

Installing the Fox Float 38 Factory Orange fork is a straightforward process, but it requires attention to detail. Follow these steps for proper installation:

1. Remove the old fork: Begin by removing the front wheel and the existing fork. Use a 5mm hex wrench to remove the stem bolts and a 6mm hex wrench to remove the fork from the head tube.
2. Prepare the new fork: Before installing, ensure that the fork is properly lubricated at the steerer tube interface. Grease should be applied lightly to prevent seizing but not interfere with the steering mechanism.
3. Install the fork: Slide the Fox Float 38 fork into the head tube of your frame. Align the fork so that it sits straight and is properly secured in the headset.
4. Attach the stem: Once the fork is in place, reattach the stem. Tighten the stem bolts in a cross pattern using a torque wrench [paid link] to the recommended torque setting, typically around 5-6 Nm.
5. Install the front wheel: Insert the front wheel back into the fork and tighten the thru-axle or quick release, ensuring it’s properly secured and aligned.
6. Check the headset: With the fork in place, check for any play in the headset. If there’s any movement, you may need to adjust the headset tension.

Adjusting the Float 38 Factory Orange Fork

The Float 38 Factory Orange suspension fork provides a variety of adjustments that can fine-tune the fork for different riding conditions. These adjustments primarily affect the fork’s air spring and damping system. Follow these steps for basic adjustments:

Air Spring Pressure

1. Determine your air pressure: Use the recommended pressure chart from Fox based on your weight and riding style. The air spring provides the support for your ride, so the correct air pressure is critical.
2. Adjust air pressure: Attach the Fox air pump to the fork’s air valve. Adjust the pressure in small increments until you achieve the desired ride feel. For a beginner, aim for a slight sag, around 15-20% of the total fork travel.

Compression Damping

1. Adjust low-speed compression: The low-speed compression knob located on the top of the fork controls how the fork reacts to small impacts. Start by turning the knob to the “Open” position for maximum comfort and gradually adjust it to the “Firm” position for improved pedaling efficiency and support.
2. Adjust high-speed compression: This dial, typically located on the left side of the fork, helps manage larger impacts like rock gardens or high-speed chatter. It should be adjusted based on your riding style, but generally, a more open setting is ideal for beginners to absorb more bumps.

Rebound Damping

1. Adjust rebound speed: The rebound adjustment dial at the bottom of the right leg controls how quickly the fork returns to its original position after compression. For smoother, more controlled rides, set the rebound to a slower speed. Fast rebound can cause the fork to feel too “bouncy,” while slow rebound can make the fork feel sluggish.

Maintenance of the Fox Float 38 Factory Orange Fork

Regular maintenance ensures the longevity and performance of your Float 38 Factory Orange fork. The key areas to maintain include the air spring, damper system, and seals.

Cleaning the Fork

1. Wipe the fork legs: Use a clean rag to wipe the fork legs after each ride. This prevents dirt and debris from entering the seals and causing wear.
2. Clean the stanchions: Apply a small amount of isopropyl alcohol to a rag and clean the stanchions to remove oils and grime.
3. Inspect seals: Check the dust wipers and seals for wear or damage. If you notice any cracks or tears, replace them immediately to avoid contamination of the fork’s internals.

Fork Servicing

1. Air spring maintenance: Every 20-30 hours of riding, it’s a good idea to inspect the air spring and top up the air pressure if needed.
2. Damper servicing: Depending on how often you ride, Fox recommends servicing the damper every 50-100 hours of use. This involves changing the oil and replacing seals in the damper system for smooth operation.
3. Rebuild the fork: If you experience a loss of performance or feel any unusual play in the fork, it may be time for a full rebuild. This process typically involves disassembling the fork, inspecting each component, and replacing any worn parts.

Troubleshooting Common Set-Up Issues

Fork Not Rebounding Properly

If the fork feels slow to return or too “bouncy,” the issue might be related to the rebound damping. Check the rebound adjustment settings and make sure it’s set correctly. If the issue persists, the oil in the damper might need changing, or the internal seals could be worn.

Excessive Stiffness or Lack of Sensitivity

If the fork feels too stiff, especially on small bumps, your air pressure may be too high. Use the Fox air pump to adjust the air pressure and reduce the pressure by 5-10 PSI to improve sensitivity. Conversely, if the fork bottoms out too easily, increase the air pressure slightly.

Noisy Fork

If you hear any unusual noises, such as creaking or knocking sounds, check that all the components are properly tightened, including the axle and headset. It’s also important to ensure that the fork is properly lubricated, especially where the fork legs meet the stanchions.

Customization and Optimization

To further optimize your ride with the Fox Float 38 Factory Orange fork, consider the following customization tips:

1. Adjust air pressure for terrain: For smoother, flowy trails, lower the air pressure slightly for better small-bump compliance. For rougher, more technical terrain, increase the air pressure to provide more support and prevent bottoming out.
2. Fine-tune compression settings: Experiment with different low and high-speed compression settings based on the terrain. For rocky, technical sections, increase the compression to reduce fork movement and improve stability.
3. Upgrade the fork’s internals: If you are an advanced rider or are looking for even more precise control, Fox offers aftermarket kits that upgrade the damper system for a more responsive and tunable feel.

Comparison with Similar Models

The Fox Float 38 Factory Orange fork competes with other high-performance forks like the RockShox Zeb and the Öhlins RXF36. Compared to the Zeb, the Float 38 offers a slightly stiffer chassis and a more refined damper system, ideal for aggressive riders. While the Öhlins RXF36 provides excellent sensitivity and plushness, the Fox Float 38 is better suited for those who prioritize precise adjustability and consistent performance in rough conditions.

Compatibility with Other Drivetrain Components

The Fox Float 38 Factory Orange fork is compatible with a wide range of drivetrains, as long as your bike is equipped with a 15mm or 20mm through-axle. Ensure that your bike’s head tube and fork steer tube match the diameter of the fork’s steerer (typically 1.5″ or tapered). Always check compatibility with your specific frame and wheelset before installation to avoid any issues with fitment.
