  • Torque wrench [paid link]
  • Float Fluid (or equivalent)
  • Fox suspension oil
  • Fox air spring tool
  • Clean rags

Installation of Float 38 Factory Orange

Installing the Fox Float 38 Factory Orange requires careful attention to detail to ensure it functions correctly. Follow these steps to properly install the fork:

  1. Remove the Old Fork: If you are replacing an existing fork, start by removing the wheel, brake caliper, and headset spacers. Use the appropriate wrenches to loosen the stem bolts and detach the fork from the frame.
  2. Prepare the New Fork: Before installation, inspect the fork for any visible damage. Apply a thin layer of suspension grease to the steerer tube to prevent creaking.
  3. Install the Fork: Slide the Float 38 Factory Orange fork into the head tube of your bike frame. Align the fork with the steering column, ensuring it sits firmly in place.
  4. Attach the Stem: Tighten the stem bolts evenly using a torque wrench [paid link] to the manufacturer-recommended specification (typically between 5-6 Nm for most models). Double-check for alignment.
  5. Install the Wheel: After securing the fork, reinstall the wheel. Ensure that the axle is properly torqued to the recommended specification.
  6. Check Brake Compatibility: Install the brake caliper and make sure the rotor is properly centered and aligned. Torque the brake mounting bolts correctly.
  7. Final Inspection: Conduct a thorough inspection to ensure everything is properly tightened and the fork moves smoothly. Check the brake functionality and headset adjustments.

Adjusting the Float 38 Factory Orange Fork

Fine-tuning the Float 38 Factory Orange will optimize its performance. The following adjustments are critical to tailor the fork to your riding style and terrain:

Air Spring Pressure Adjustment

The Float 38 features an air spring system that allows you to adjust the fork’s ride height and spring rate. Use the Fox air spring tool to adjust the pressure.

  1. Check Your Rider Weight: Before adjusting, ensure you know your rider weight, as this will determine the ideal air pressure. Refer to Fox’s recommended air pressure chart for guidance.
  2. Inflate or Deflate: Use a shock pump to adjust the air pressure to match your weight and riding style. Generally, start with a mid-range pressure and adjust based on feel.

Compression Damping Adjustment

The compression settings control how the fork responds to impacts and terrain. The Float 38 Factory Orange has adjustable low-speed and high-speed compression settings.

  1. Set Low-Speed Compression: For general trail riding, set the low-speed compression to a medium setting. This helps control how the fork handles small bumps and impacts.
  2. Adjust High-Speed Compression: For more aggressive riding or enduro trails, fine-tune the high-speed compression to manage larger hits. Increase the compression to prevent bottoming out on big landings.

Rebound Damping Adjustment

Rebound damping controls how quickly the fork returns after compressing. For smoother riding, adjust it to ensure the fork doesn’t return too quickly or too slowly.

  1. Turn the Rebound Dial: Start by setting the rebound dial to the middle setting. Ride the bike and adjust the rebound faster (clockwise) or slower (counterclockwise) depending on terrain conditions.

Routine Maintenance of Float 38 Factory Orange

Regular maintenance is crucial to ensure the Float 38 Factory Orange remains in peak [paid link] condition. Follow these essential steps for servicing:

Cleaning

  1. Wipe Down the Fork: After each ride, clean the fork with a soft cloth to remove dirt and debris. Ensure the stanchions remain free of grime, as this can wear out seals.
  2. Check the Dust Wipers: Inspect the dust wipers for any buildup of dirt or mud. Clean them regularly with water and a non-abrasive cleaner.

Suspension Fluid

Changing the suspension fluid is essential for maintaining damping performance. Fox recommends changing the fluid in your Float 38 Factory Orange every 50-100 hours of riding.

  1. Disassemble the Fork: Remove the fork from the bike and disassemble the lower legs. Use a T20 Torx driver to remove the bolts securing the lower legs.
  2. Drain the Old Fluid: Once the lower legs are removed, drain the old fluid completely.
  3. Reassemble and Refill: Replace the seals if necessary, then refill the fork with new Fox suspension oil. Ensure the correct oil level is maintained, as specified in the user manual.

Air Spring Maintenance

  1. Check for Leaks: Inspect the air spring for any signs of leakage or damage. Over time, seals can wear out, leading to pressure loss.
  2. Re-grease the Air Spring: Apply a light coating of suspension grease to the air spring components during maintenance to keep them working smoothly.

Troubleshooting Common Set-up Issues

Fork Not Holding Air Pressure

If your Float 38 Factory Orange is losing air pressure, it could indicate a leak. Check the air valve for any visible damage. If the valve is intact, inspect the seals for wear, and replace them if needed.

Fork Bottoming Out Too Easily

If the fork is bottoming out frequently, increase the air pressure or adjust the compression damping to handle more aggressive impacts.

Fork Not Returning Properly

If the fork is not rebounding correctly, check the rebound settings and adjust accordingly. If the problem persists, it could indicate a need for a suspension oil change or internal servicing.

Customization and Optimization for Better Performance

To further enhance the performance of your Float 38 Factory Orange, consider the following options:

  1. Upgrade to the Latest Air Spring Technology: Fox occasionally releases updated air springs with improved responsiveness. Consider upgrading if you’re looking for additional tuning options.
  2. Tune the Damping Circuit: Fine-tuning the damping circuit can provide more control over the fork’s performance. Experiment with different settings for the compression and rebound damping to match your riding style and terrain.
  3. Use a Custom-Tuned Damper: If you’re serious about performance, consider using a custom-tuned damper for your Float 38. These are available through Fox or third-party suppliers and can offer more precision in handling.

Comparing the Float 38 Factory Orange with Other Models

When comparing the Float 38 Factory Orange to similar forks, it’s important to consider its travel range, weight, and intended use. The Float 38 is specifically designed for aggressive trail riding and enduro, which makes it heavier and more robust than cross-country or all-mountain models.

  • Fox 36: While the Fox 36 is similar in performance, the Float 38 is designed with slightly more travel and a stiffer chassis, making it better suited for enduro and downhill applications.
  • RockShox ZEB: The ZEB is another aggressive trail fork with a similar travel range. However, the Float 38 tends to offer a more refined damping system, giving it an edge in handling complex terrain.

Understanding Compatibility with Other Drivetrain Components

The Float 38 Factory Orange is compatible with a wide range of modern mountain bike drivetrains, but there are a few considerations to keep in mind:

  • Headset Compatibility: Ensure that your bike frame is compatible with the steerer tube size of the Float 38. This model typically comes with a 1.5-inch tapered steerer tube.
  • Axle Compatibility: The Float 38 uses a 15mm or 20mm through-axle, so verify that your bike’s frame supports this axle size.
  • Brakes: The fork is designed to be compatible with both 180mm and 203mm disc brake rotors, so check that your brake system can accommodate these sizes.

Properly servicing and maintaining your Float 38 Factory Orange will help extend its lifespan and keep it performing at its best, ensuring you enjoy a smooth, controlled ride in even the most challenging conditions.
