The Float SL Factory rear shock from Fox is a premium shock designed to provide high-performance suspension for cross-country and trail riders. Known for its lightweight design and exceptional responsiveness, this shock offers an optimal balance of comfort and control. Whether you’re installing, adjusting, maintaining, or troubleshooting your Float SL Factory rear shock, this comprehensive guide will cover all aspects of this component to ensure optimal performance and longevity.

Installation of the Float SL Factory Rear Shock

Installing the Float SL Factory rear shock correctly is crucial for ensuring proper function and comfort. Follow these steps for a successful installation:

  1. Remove the Old Shock (if applicable):
    • Use a 5mm Allen wrench [paid link] to remove the bolts that secure the old shock to the frame.
    • Carefully slide the shock out of its mount, ensuring no damage to the frame or the shock itself.
  2. Prepare the New Shock:
    • Check the new Float SL Factory rear shock for any signs of damage or defects.
    • Make sure the shock is properly inflated according to the manufacturer’s specifications, using a shock pump.
  3. Install the Shock:
    • Slide the new Float SL Factory shock into the mounting location on the frame.
    • Secure the shock in place by tightening the mounting bolts using the appropriate torque (usually around 10-12 Nm depending on the frame manufacturer).
    • Ensure the shock is aligned correctly, with no misalignment that could affect performance.
  4. Check the Suspension Linkage:
    • After securing the shock, check the linkage and movement to ensure the suspension operates smoothly without any binding.
  5. Test the Installation:
    • Perform a visual check to ensure all bolts are tightened and there is no excessive play in the shock mount.
    • Compress the shock manually to check for smoothness and free movement.
    • Take the bike for a test ride to confirm proper installation and functioning.

Adjusting the Float SL Factory Rear Shock

The Float SL Factory rear shock comes with multiple adjustment options to fine-tune your ride. These include air spring pressure, rebound damping, and compression settings. Here’s how to adjust each setting:

Air Spring Pressure

  • Adjust for Rider Weight: Use a shock pump to adjust the air pressure in the Float SL Factory shock. Check the manufacturer’s recommended range for your weight and riding style.
  • Start with the Basics: Inflate the shock to the baseline pressure, then check sag by sitting on the bike and measuring the amount of suspension travel used. Adjust as needed to achieve around 25-30% sag for most riders.

Rebound Damping

  • Fine-Tuning Rebound Speed: The rebound adjustment controls how quickly the shock returns after compression. Turn the rebound knob clockwise to slow down the rebound or counterclockwise to speed it up.
  • Optimal Setting: Set the rebound so that the shock feels responsive but doesn’t return too quickly, causing instability, or too slowly, causing a “spongy” feel.

Compression Damping

  • Adjust for Terrain: Compression damping controls how the shock reacts to impacts and small bumps. Use the low-speed compression dial to fine-tune for comfort on rough trails.
  • Softer Settings: For smoother rides, set the compression to a softer setting, which allows more travel and better absorption of small bumps.
  • Stiffer Settings: For aggressive riding or racing, use a stiffer compression setting to prevent excessive travel during high-impact landings.

Maintaining the Float SL Factory Rear Shock

Routine maintenance is essential to keep your Float SL Factory rear shock performing optimally. Follow these steps to extend the life of your shock:

  1. Clean the Shock Regularly:
    • Use a clean, damp cloth to wipe down the shock after every ride. Make sure to remove any dirt or debris that may have accumulated on the shock body.
    • Avoid using harsh chemicals or solvents, as these can damage the seals.
  2. Check for Leaks:
    • Inspect the shock for any signs of oil leakage around the seals. If oil is leaking, the seals may need replacement.
  3. Service the Shock:
    • Fox recommends servicing the shock annually or after every 200 hours of riding. This includes changing the shock’s oil and replacing seals.
    • A professional service center can provide a complete overhaul, ensuring all components are cleaned and lubricated.
  4. Lubricate the Shock:
    • Regularly lubricate the shock’s mounting bolts to prevent corrosion and maintain smooth operation.
  5. Check for Shock Wear:
    • Inspect the shock for any signs of wear or damage, including worn-out seals, dents, or cracks in the body. If any issues are found, replace the shock or specific components as needed.

Troubleshooting Common Set-Up Issues

If your Float SL Factory rear shock isn’t performing as expected, here are some common issues and how to troubleshoot them:

Issue 1: Excessive Sag

  • Cause: Too little air pressure in the shock.
  • Solution: Check and adjust the air pressure according to your weight and riding style. Ensure the sag is within the recommended range of 25-30%.

Issue 2: Harsh Ride or Too Stiff

  • Cause: Compression damping set too high or incorrect air pressure.
  • Solution: Adjust the compression damping to a softer setting. Also, check the air pressure to ensure it’s appropriate for your weight and preferred ride quality.

Issue 3: Bouncy or Slow Rebound

  • Cause: Rebound damping set too slow or too fast.
  • Solution: Adjust the rebound damping for a smoother, more controlled return. A proper setting should prevent the shock from bouncing or being too slow to respond.

Issue 4: Leaking Oil

  • Cause: Worn seals or damage to the shock body.
  • Solution: Inspect the shock for leaks. If oil is leaking, take the shock to a professional service center for seal replacement and further inspection.

Customization and Optimization for Better Performance

To get the best performance from your Float SL Factory rear shock, consider these customization and optimization tips:

  • Set Sag Based on Riding Style: For cross-country riders, aim for a higher sag percentage to ensure smooth pedaling and better traction. For trail riders, slightly less sag may be optimal for better control on rough terrain.
  • Fine-Tune Compression Settings: Customize the compression damping based on the terrain you ride most often. Softer settings are ideal for smoother trails, while stiffer settings can help on more aggressive terrain.
  • Upgrade the Air Spring: Consider upgrading to a custom air spring to fine-tune your shock’s responsiveness and overall performance.
  • Use the Proper Mounting Hardware: Ensure that the shock’s mounting hardware is compatible with your frame and is correctly torqued to avoid potential issues like play or movement in the shock.

Comparison with Similar Models

The Float SL Factory rear shock competes with several other high-performance shocks, such as the Fox DPX2 and RockShox Monarch. However, the Float SL Factory stands out due to its ultralight design, making it a popular choice for cross-country and endurance riders. Here’s how it compares:

  • Float SL Factory vs DPX2: The Float SL Factory is lighter than the DPX2, which makes it better suited for cross-country riders who prioritize weight savings. The DPX2, however, offers more adjustability, including a separate low-speed compression circuit, making it better suited for aggressive trail riders.
  • Float SL Factory vs RockShox Monarch: The Monarch offers solid performance at a lower price point, but it’s not as lightweight as the Float SL Factory. The Monarch may be more suitable for budget-conscious riders who don’t need the precise adjustments offered by the Float SL Factory.

Compatibility with Other Drivetrain Components

The Float SL Factory rear shock is compatible with a wide range of mountain bike frames, but it’s essential to ensure proper fitment and alignment with your specific bike’s geometry. The shock is designed to work seamlessly with modern drivetrains, including SRAM and Shimano systems, as long as the frame is compatible with a rear shock of the correct dimensions. Always verify the shock’s eye-to-eye measurement and stroke length to ensure compatibility with your bike.

In conclusion, the Float SL Factory rear shock is an excellent choice for riders who want top-tier suspension performance without compromising weight. By following the installation and adjustment procedures, maintaining the shock regularly, and troubleshooting any issues, you can ensure a smooth and enjoyable ride every time.
