Installation of the Float X2 Performance Elite Rear Shock

Installing the Float X2 Performance Elite rear shock is a straightforward process, but it requires attention to detail to ensure optimal performance and safety.

Tools Required

  • 5mm Allen wrench [paid link]
  • Torque wrench [paid link]
  • Shock pump
  • Grease
  • Spacers (if required)
  • 10mm wrench
  • Needle nose pliers

Step-by-Step Installation

  1. Prepare the Mounting Points: Ensure that the frame and shock mount points are clean and free of debris. Apply a thin layer of grease to the mounting hardware to prevent corrosion and ease the installation process.
  2. Install the Shock: Attach the shock to the frame by aligning the shock’s eyelets with the mounting points. Secure the shock with the provided hardware, ensuring the bolts are threaded properly.
  3. Tighten the Mounting Bolts: Using a 5mm Allen wrench [paid link] and a torque wrench [paid link], tighten the mounting bolts to the recommended torque specification (usually 40-50 Nm, but refer to your bike’s manual).
  4. Set Air Pressure: Using a shock pump, set the air pressure according to the rider’s weight and riding style. The recommended air pressure can be found in the shock’s manual or determined through suspension setup guides.
  5. Fine-Tuning: Adjust the rebound and compression settings as needed. The Float X2 Performance Elite offers separate low-speed and high-speed compression adjustments, allowing you to fine-tune the shock to your specific needs.

Once installed, test the shock by pushing down on the rear end of the bike and checking the shock’s movement. Make sure the shock is working smoothly without any binding or unusual noises.

Adjusting the Float X2 Performance Elite Rear Shock

The Float X2 Performance Elite offers advanced adjustment features that allow for a highly customizable setup. Understanding these adjustments will enable you to dial in the shock for different terrains and riding styles.

Compression Adjustments

  1. High-Speed Compression: This controls how the shock responds to fast impacts, such as hitting rocks or roots. Higher settings result in a firmer feel, reducing bottoming out, while lower settings allow the shock to compress more easily for better traction.
  2. Low-Speed Compression: This adjustment affects how the shock behaves under slow, steady forces like pedaling. Increasing the low-speed compression setting can reduce unwanted suspension movement during climbs or while sprinting, improving pedaling efficiency.

Rebound Adjustment

The rebound adjustment controls how quickly the shock returns to its original position after compression. If the rebound is too fast, the bike may feel twitchy, while too slow can cause a sluggish feel. Finding the right balance is key to maintaining control and comfort.

Air Spring Pressure

The air spring pressure can be adjusted to match the rider’s weight and riding style. The right air pressure ensures the shock provides the appropriate amount of travel and support. Start with the recommended pressure, then fine-tune based on feel and performance.

Maintenance of the Float X2 Performance Elite Rear Shock

Regular maintenance of the Float X2 Performance Elite is essential to ensure longevity and optimal performance. Keeping the shock clean, maintaining proper air pressure, and inspecting key components will prevent issues and prolong its lifespan.

Cleaning the Shock

  1. Wipe the Shock: After each ride, use a clean cloth to wipe down the shock. Pay special attention to the stanchion (the upper part of the shock that moves inside the body) to remove dirt and debris.
  2. Inspect for Leaks: Check for any oil or air leaks. Leaks can lead to a loss of performance, so if any are found, the shock may need to be serviced.
  3. Grease the Mounting Points: Periodically remove the shock and clean the mounting hardware. Apply fresh grease to prevent corrosion.

Air Pressure and Rebound Check

  1. Air Pressure: Check the shock’s air pressure regularly, as it may fluctuate over time. Use a shock pump to adjust the pressure as necessary, based on the rider’s weight and the type of riding.
  2. Rebound and Compression Settings: Verify that the rebound and compression adjustments are still set to the preferred settings. Over time, changes in riding conditions may require further adjustments.

Full Service

Fox recommends a full service of the Float X2 Performance Elite rear shock every 100 hours of riding. This includes a complete oil change, inspection of internal components, and re-lubing of the seals. This is critical for maintaining the shock’s performance and ensuring it continues to perform optimally under demanding conditions.

Troubleshooting Common Issues

Issue 1: Saggy or Soft Suspension

If the rear shock feels soft or is sagging excessively, it may be due to incorrect air pressure or worn-out seals.

  • Solution: First, check the air pressure and adjust it according to the rider’s weight. If the pressure is correct but the problem persists, inspect the shock for any oil leaks or worn seals, which may require a service.

Issue 2: Lack of Rebound Control

If the shock is not returning to its original position quickly enough, it may feel sluggish and unresponsive.

  • Solution: Adjust the rebound damping to a faster setting. If this does not resolve the issue, the shock may require a service to replace internal components.

Issue 3: No Compression Resistance

If the shock feels overly plush and doesn’t offer adequate resistance to compression, it may indicate an issue with the compression adjustments or internal wear.

  • Solution: Check the high-speed and low-speed compression settings. If they are set correctly and the issue persists, an internal service may be necessary.

Optimizing Performance of the Float X2 Performance Elite Rear Shock

To get the most out of the Float X2 Performance Elite, riders can make several adjustments based on their riding style, terrain, and personal preferences.

Tuning for Different Terrain

  1. For Technical Downhills: Increase high-speed compression and lower the rebound to prevent the shock from bouncing back too quickly. This will improve control and stability.
  2. For Enduro and Trail Riding: A balanced setup with medium settings on both low and high-speed compression works well. Adjust the air pressure to ensure enough travel for rough descents without sacrificing pedaling efficiency.
  3. For Climbing: Increase low-speed compression to reduce unwanted suspension movement. Lowering the rebound slightly can also improve control during climbs.

Shock Customization

The Float X2 Performance Elite offers a range of adjustments, including external volume spacers, which allow the rider to adjust the shock’s progressiveness. Adding spacers will make the shock more progressive, preventing bottoming out on big hits, while removing spacers provides a more linear feel, better for smoother, less technical terrain.

Comparing the Float X2 Performance Elite with Similar Models

The Float X2 Performance Elite is one of the top choices for aggressive riders looking for customizable performance. When compared to other rear shocks in the market, such as the RockShox Super Deluxe Coil and the Marzocchi Bomber CR, the Float X2 Performance Elite stands out in the following ways:

  • Customization: The Float X2 offers a wide range of compression and rebound adjustments, allowing for fine-tuning to the rider’s specific needs.
  • Weight: It is lighter than coil shock options like the RockShox Super Deluxe Coil, making it more ideal for riders focused on weight savings for enduro or cross-country use.
  • Performance: Riders report that the Float X2 provides a smoother and more responsive feel, particularly on technical descents, due to its superior damping and suspension control.

Compatibility with Other Drivetrain Components

The Float X2 Performance Elite is compatible with most modern mountain bike frames and drivetrains. However, compatibility can vary based on the specific frame and suspension design. Riders should always verify that the shock’s eyelet size, stroke length, and mounting hardware match the frame specifications. Additionally, the shock’s air spring system should be tuned to complement the bike’s overall geometry and suspension design.

Conclusion

The Float X2 Performance Elite rear shock is a premium option designed for riders who seek exceptional performance across a variety of riding conditions. By understanding its installation, adjustment, maintenance, and troubleshooting procedures, riders can optimize its performance and ensure longevity. Whether you’re a competitive racer or an avid trail rider, the Float X2 Performance Elite provides the control, responsiveness, and durability needed for any challenging ride.
