Tools Required

  • Fox 3mm, 4mm, 5mm, and 6mm Allen wrenches [paid link]
  • Torque wrench [paid link]
  • Suspension fluid (Fox Float fluid)
  • Clean, lint-free rags
  • Shock pump (compatible with Fox shocks)
  • Fox Float X seal kit (for complete service)
  • 10mm socket wrench
  • Plastic scraper or soft brush for cleaning
  • Isopropyl alcohol (for cleaning)
  • Silicone grease
  • Small container for oil or fluid collection
  • Oil syringe for accurate fluid filling

Disassembly and Cleaning

Before servicing your Float X Performance [paid link] Elite shock, it’s essential to disassemble and clean the components properly.

Step 1: Removing the Shock from the Bike

  • Loosen the mounting bolts: Use the appropriate size Allen wrench [paid link] to remove the shock from the frame.
  • Support the bike: Secure your bike to prevent it from moving as you remove the shock.
  • Inspect the mounting hardware: Check for any wear or damage on the mounting bolts or bushings and replace them if necessary.

Step 2: Cleaning the Shock

  • Clean the shock body: Use a clean, lint-free rag to wipe down the shock body, removing any dirt and debris. Be gentle to avoid scratching the surface.
  • Use isopropyl alcohol: For deeper cleaning, apply a small amount of isopropyl alcohol to the rag and clean the shock’s stanchion. Avoid contact with the shock’s internal parts.

Step 3: Inspecting for Damage

  • Check for air leaks: Inspect the air sleeve for any signs of leaks. This can be done by checking the shock’s air pressure and ensuring it holds steady after being inflated.
  • Examine the shock eyelets: Look for any excessive wear or damage, particularly around the mounting points. If the eyelets are damaged, it may be necessary to replace them.

Rebuilding and Servicing the Float X Performance Elite

The Float X Performance [paid link] Elite rear shock uses a highly specialized system of air chambers and damping mechanisms. Regular servicing is crucial for maintaining performance, particularly if you ride in challenging conditions.

Step 1: Removing the Air Sleeve and Damping Assembly

  • Remove the air valve: Unscrew the air valve using your 4mm Allen wrench [paid link].
  • Detach the air sleeve: Carefully pull the air sleeve off the shock body. This step may require slight manipulation to loosen the sleeve if it is stuck.
  • Disassemble the damping unit: The damping assembly can be removed by loosening the retaining screws. Take care not to damage the internal components, especially the rebound and compression adjustments.

Step 2: Replacing the Seals

  • Remove the old seals: Use a plastic scraper or soft brush to remove the old seals from the shock body. Be gentle to avoid damaging the shock.
  • Install new seals: Place the new seals from your Float X seal kit into their respective positions. Ensure each seal is properly seated.

Step 3: Lubricating the Components

  • Apply silicone grease: Lightly grease the air sleeve and any moving parts with silicone grease to ensure smooth operation and prevent future seal wear.
  • Lubricate the shock shaft: A small amount of suspension fluid should be added to the shaft before reassembly. This ensures that the shock operates smoothly and prevents friction during compression.

Step 4: Reassembling the Shock

  • Reinstall the damping assembly: Carefully insert the damping unit back into the shock body and secure it with the retaining screws.
  • Reattach the air sleeve: Slide the air sleeve back over the shock body, ensuring it fits snugly without pinching any seals.
  • Secure the air valve: Screw the air valve back into its position, ensuring it is tightened securely.

Filling and Adjusting the Shock

Once the shock is reassembled, the next step is to fill it with the appropriate air pressure and make fine adjustments for optimal performance.

Step 1: Setting Air Pressure

  • Use the shock pump: Attach the shock pump to the valve and begin inflating the shock to the desired pressure. Fox recommends setting the pressure based on your weight and riding style. For the Float X Performance Elite, air pressure can range from 150-250 psi, depending on rider preferences and suspension settings.
  • Check the air pressure: After inflating, check the air pressure with the pump gauge and ensure that it holds steady. If you notice a drop in pressure, inspect the shock for leaks.

Step 2: Adjusting the Rebound and Compression

  • Adjust rebound: The rebound adjuster controls how quickly the shock returns to its original position after compression. Use the dial on the shock to adjust the rebound based on your riding conditions.
  • Adjust compression: The compression adjuster determines how much resistance the shock provides during compression. Adjust this dial according to your riding style and terrain. A firmer setting is typically preferred for aggressive riders, while a softer setting works well for smoother, more technical trails.

Troubleshooting Common Set-Up Issues

While the Float X Performance Elite is a high-performance shock, it’s not immune to issues that may arise over time. Here are some common problems and how to troubleshoot them:

Air Leaks

  • Cause: An air leak can occur if the seals or valves are not properly installed.
  • Solution: Inspect all seals, valves, and the air sleeve for damage or improper installation. If necessary, replace the seals and ensure all parts are correctly tightened.

Lack of Rebound or Compression Control

  • Cause: This could be due to inadequate fluid levels or contamination in the damping assembly.
  • Solution: Rebuild the damping assembly, ensuring all components are cleaned thoroughly and that the correct amount of suspension fluid is used. Check for any visible damage or wear on the damping components.

Unusual Noises During Operation

  • Cause: Unusual noises, such as clicking or popping, often indicate air or debris trapped within the shock.
  • Solution: Remove the air sleeve and check for any foreign material inside the shock body. Refill the shock with suspension fluid and ensure that the seals are in good condition.

Customization and Optimization for Better Performance

To get the most out of your Float X Performance Elite, it’s essential to fine-tune its settings to match your riding style and terrain. Here’s how to customize the shock for optimal performance:

Fine-Tuning the Air Pressure

  • Tailor to rider weight: Air pressure should be adjusted based on your weight and the type of terrain you’ll be riding. Lighter riders typically need less air pressure, while heavier riders require more. A good starting point is to set the air pressure at around 30-35% of the shock’s total travel.

Setting Rebound and Compression for Terrain

  • Technical trails: If you are riding on technical terrain with lots of drops and obstacles, increase the compression to absorb impacts better, and dial in a slower rebound for smoother transitions.
  • Fast, flowy trails: For faster trails with fewer impacts, reduce the compression and rebound damping for a quicker, more responsive feel.

Comparison with Similar Models

While the Float X Performance Elite is an outstanding choice for aggressive trail riders, it’s useful to consider how it compares to other models in Fox’s line-up.

  • Fox Float DPX2: Offers similar performance but with a slightly more aggressive compression platform for riders who prioritize downhill performance. The Float X, however, offers better sensitivity and is ideal for all-around trail riding.
  • Fox Float X2: The Float X2 is the premium model in the Fox lineup, offering more adjustment options and a superior damping system for riders seeking high-end performance in technical riding.

Compatibility with Other Drivetrain Components

The Float X Performance Elite rear shock is designed to integrate seamlessly with other high-performance Fox suspension systems, but compatibility with other drivetrain components should be verified.

  • Shock mount size: Ensure that the shock’s eyelet size matches the frame’s mounting points.
  • Linkage compatibility: Some frames with a particular linkage design may require a specific shock stroke length or mounting configuration. Always double-check compatibility before installation.
  • Spring rate: If you’re upgrading or swapping out shocks, ensure the spring rate (air pressure in this case) matches the intended riding style and frame setup.

By following these maintenance tips, troubleshooting common issues, and adjusting your settings based on terrain, your Fox Float X Performance Elite shock will provide superior performance for years to come.
