• Adjustable Damping: The shock allows for fine-tuning of both rebound and compression damping, offering a customizable ride experience suited to different types of terrain.
• Durability: The shock’s design and materials ensure long-lasting performance, even under the most demanding conditions.

Installation of the Fox Float SL Performance Rear Shock

Installing the Fox Float SL Performance rear shock on your bike is a straightforward process, but it does require careful attention to detail. Follow these steps for a proper installation.

Tools Required:

• Torque wrench [paid link]
• 5mm Allen wrench [paid link]
• 6mm Allen wrench [paid link]
• Shock mount hardware (specific to your bike frame)

Installation Steps:

1. Prepare the Shock Mount: Ensure that the shock mount on your bike frame is clean and free of any debris. If necessary, apply a small amount of grease to the shock mounting points to prevent creaking.
2. Attach the Shock to the Frame: Carefully align the mounting hardware on the Float SL Performance with the corresponding mounts on your bike frame. Insert the hardware into place.
3. Secure the Shock: Using the 5mm Allen wrench, tighten the bolts to the recommended torque setting (typically 30-35 Nm). Use the torque wrench [paid link] to ensure proper tightness without over-tightening.
4. Check for Proper Alignment: After installation, check that the shock is securely mounted and moves freely without any interference from the frame or linkage.

Adjustment and Tuning for Optimal Performance

The Fox Float SL Performance rear shock comes with a variety of adjustment options that allow you to fine-tune the shock’s performance. These adjustments help you optimize the shock for different terrain and riding styles, providing greater comfort and control.

Air Spring Pressure

The first adjustment to consider is the air spring pressure, which directly affects the shock’s sag and overall performance. The Float SL Performance uses an air spring, which can be adjusted based on your weight and riding preferences.

1. Determine Recommended Air Pressure: Refer to Fox’s suggested air pressure guidelines based on your weight. This is typically around 20-25% of the total shock travel.
2. Adjust Air Pressure: Using a shock pump, add or release air to achieve the correct pressure. Be mindful not to overinflate, as this could lead to a stiff ride and reduced comfort.

Rebound Damping

Rebound damping controls the rate at which the shock returns to its neutral position after being compressed. Adjusting the rebound damping allows you to fine-tune how quickly or slowly the shock rebounds, which can affect the bike’s handling.

1. Set the Rebound: Begin with the rebound dial set to the middle position, then adjust based on how the shock feels. If the shock rebounds too quickly, it can cause instability; if it rebounds too slowly, it can lead to a harsh ride.
2. Fine-Tune for Conditions: For aggressive riding or fast descents, set the rebound to a slower setting, and for cross-country or climbing, a faster rebound may be preferable.

Compression Damping

Compression damping determines how much resistance the shock provides when it is compressed. The Float SL Performance allows for both low-speed and high-speed compression adjustments.

1. Low-Speed Compression: Adjust the low-speed compression to control how the shock responds to pedal forces and small bumps. A firmer setting can reduce pedal bob and improve efficiency on climbs.
2. High-Speed Compression: This adjustment affects how the shock responds to larger hits or aggressive descents. If you’re riding on rough, technical terrain, increasing the high-speed compression can help reduce bottoming out.

Maintenance and Troubleshooting

Regular maintenance is essential for keeping your Fox Float SL Performance rear shock in top condition. Proper care will extend the life of your shock and maintain its performance.

Maintenance Steps:

• Clean the Shock Regularly: After each ride, wipe down the shock with a clean, damp cloth to remove dirt and debris. This prevents contaminants from entering the shock seals and affecting performance.
• Check for Leaks: Inspect the shock for any signs of air or oil leaks. If you notice any issues, take the shock to a qualified technician for a rebuild or seal replacement.
• Lubricate the Shock: Periodically apply lubricant to the shock’s bushings to ensure smooth operation. This will prevent squeaks and improve overall performance.

Troubleshooting Common Issues:

• Excessive Sag: If you notice that the shock sags too much, it may be a sign that the air pressure is too low. Recheck the pressure and adjust accordingly.
• Bottoming Out: If the shock is bottoming out frequently, consider increasing the compression damping or adding more air pressure to reduce travel.
• No Rebound: If the shock is not rebounding, it could be due to a faulty rebound valve or inadequate oil levels. Check for leaks and seek professional servicing if necessary.

Comparing the Fox Float SL Performance to the Competition

When comparing the Float SL Performance rear shock to other models on the market, several key factors come into play. The Float SL Performance stands out primarily for its lightweight construction and advanced EVOL air spring technology. However, there are other models that offer similar features with slight differences in design, performance, and price.

Float SL Performance vs. RockShox Super Deluxe

• Weight: The Float SL Performance is lighter than the RockShox Super Deluxe, making it a better choice for weight-conscious riders.
• Damping System: The Super Deluxe features a more advanced compression system, which may be preferable for riders who need more precise control on technical descents.
• Price: The Float SL Performance is typically priced higher than the Super Deluxe, but the weight savings and improved small bump sensitivity may justify the extra cost for some riders.

Float SL Performance vs. Cane Creek Double Barrel Inline

• Customization: The Cane Creek Double Barrel Inline offers more adjustability options, including separate high and low-speed compression and rebound controls. However, this adds complexity that may not be necessary for all riders.
• Performance: Both shocks deliver excellent performance, but the Float SL Performance is better suited for riders looking for a balance between weight and comfort on cross-country or trail rides, while the Double Barrel Inline is more suited for aggressive downhill riders.

Compatibility with Other Drivetrain Components

The Fox Float SL Performance rear shock is compatible with a wide range of mountain bike frames, particularly those designed for cross-country and trail riding. Its lightweight design makes it ideal for bikes that prioritize climbing efficiency, and it pairs well with other high-end drivetrain components, such as Shimano XTR or SRAM Eagle groupsets.
