Installation of the Float SL Factory Rear Shock
Installing the Float SL Factory rear shock correctly is crucial to ensure optimal performance and longevity. Follow these steps:
- Prepare the Bike: Start by removing the rear wheel and the old shock if one is already installed. Use a 5mm Allen wrench to remove the bolts securing the shock to the frame.
- Check Compatibility: Verify that the new Float SL Factory shock is compatible with your frame. Ensure that the mounting hardware fits properly and the shock’s length and stroke are correct for your bike’s geometry.
- Install the Shock: Position the Float SL Factory rear shock on the frame and align it with the shock mounts. Tighten the mounting bolts with a 5mm Allen wrench, being careful not to overtighten. Use a torque wrench [paid link] to tighten to the manufacturer’s recommended torque specification.
- Set Sag and Air Pressure: Using a shock pump, set the recommended air pressure for your weight and riding style. Check the sag by sitting on the bike and ensuring the shock compresses to the correct amount (usually around 25-30% of total travel).
- Final Check: Double-check that all bolts are properly tightened and that there are no clearance issues with the frame.
Regular Maintenance of the Float SL Factory Rear Shock
Maintaining the Float SL Factory rear shock involves routine cleaning, lubricating seals, and ensuring the shock is functioning correctly.
Cleaning the Shock
- Wipe Down the Shock After Every Ride: After each ride, clean the rear shock with a clean rag to remove dirt, mud, and debris. This prevents grit from damaging the seals and causing wear.
- Use Isopropyl Alcohol: For a more thorough clean, dampen a rag with isopropyl alcohol and wipe down the shock. This will help remove any grease or oil buildup without damaging the shock’s surfaces.
- Inspect for Leaks: After cleaning, inspect the shock for any signs of oil leaks around the seals. If you notice any leaking, it’s time to replace the seals.
Lubricating the Seals
The seals of the Float SL Factory shock are critical for preventing dirt and moisture from entering the shock. Regular lubrication extends their lifespan and maintains smooth performance.
- Apply Light Grease: Use a small amount of grease on the shock’s seals to maintain their lubricity. Avoid over-greasing as this can attract dirt.
- Check for Dry Seals: If the seals look dry or cracked, apply more grease and work it in by compressing the shock slightly.
Suspension Fluid Maintenance
To keep the Float SL Factory rear shock performing at its best, it’s important to service the internal suspension fluid. This step should be done every 50-100 hours of riding, depending on the conditions.
- Remove the Shock from the Frame: Use the 5mm Allen wrench to remove the shock from the frame. Be sure to place it in a clean area to prevent contamination during servicing.
- Drain the Old Fluid: Using a plastic syringe or similar tool, remove the old suspension fluid from the shock. Dispose of it properly.
- Refill with Fresh Suspension Fluid: Using the syringe, refill the shock with the recommended fluid. Make sure you are using the exact type of fluid specified by Fox for the Float SL Factory rear shock.
- Reinstall the Shock: Once the new fluid is in place, reattach the shock to the frame, ensuring all bolts are tightened to the correct torque.
Troubleshooting Common Set-Up Issues
Even with regular maintenance, you may encounter some issues with your Float SL Factory rear shock. Here’s how to troubleshoot the most common problems:
Loss of Air Pressure
If the rear shock loses air pressure, it may feel soft or bottom out during rides.
- Check for Leaks: Inspect the air valve and the shock body for any visible leaks. If there is a slow leak, it could be due to a damaged valve core or worn seals. If you cannot find any obvious signs of damage, try re-inflating the shock to the recommended pressure and check again after a short ride.
- Replace the Valve Core: If a leak persists, it’s time to replace the valve core. This is a relatively simple fix, and you can order replacement parts from Fox or an authorized dealer.
Inconsistent Suspension Performance
If the shock feels inconsistent, with noticeable bobbing or bouncing, it may require a more thorough service.
- Inspect the Air Spring: The air spring could be out of tune. Recheck the air pressure and ensure the sag is correctly set.
- Suspension Fluid Issues: If the shock is still underperforming, it may be due to old or low suspension fluid. Follow the fluid replacement procedure outlined above to restore smooth operation.
Customization and Optimization for Better Performance
While the Float SL Factory rear shock is already an excellent performer out of the box, customization can help fine-tune it to your specific needs.
Adjusting Rebound and Compression Damping
The Float SL Factory shock comes with adjustable rebound and compression damping to help you fine-tune the ride.
- Rebound Damping: Adjust the rebound damping to control how quickly the shock returns after compression. A slower rebound is ideal for technical trails, while faster rebound is better for smoother trails.
- Compression Damping: Adjust the compression damping to control how the shock responds to impacts. A firmer setting helps with aggressive riding or carrying heavy loads, while a softer setting is preferable for smooth, fast riding.
Optimizing Air Pressure
Experiment with slightly different air pressures based on your weight, riding style, and terrain. If you find that the shock feels too soft or too harsh, fine-tune the pressure to achieve the desired sag and comfort.
Comparison with Other Rear Shocks
When comparing the Float SL Factory rear shock with other models in the same class, it stands out for its lightweight construction, high-quality performance, and precise tuning options. Other models, such as the RockShox Super Deluxe and the DT Swiss EXA, may offer similar features, but they differ in terms of weight, adjustment range, and performance characteristics.
- Fox Float SL Factory: Best for riders looking for a lightweight shock with high performance and customizable settings.
- RockShox Super Deluxe: Offers more adjustment options but is heavier and may not be as efficient for cross-country riders.
- DT Swiss EXA: A durable shock, but with fewer tuning options compared to the Float SL Factory, making it better suited for riders who prioritize simplicity over customization.
Understanding Compatibility with Other Drivetrain Components
The Float SL Factory rear shock is compatible with most modern mountain bike frames designed for air shocks. However, before installing it, ensure that the shock’s mounting system matches your frame’s specifications. This includes checking the shock’s eye-to-eye length and stroke, as well as ensuring the correct type of mount (e.g., Trunnion or standard mounting hardware).
When pairing the Float SL Factory rear shock with other drivetrain components, consider the overall geometry of your bike. The shock’s performance will be affected by factors such as the rear triangle design, the suspension linkages, and how the shock interacts with the rest of your bike’s suspension system.
By carefully matching the Float SL Factory rear shock with compatible components, you’ll maximize its performance and ensure a smooth, efficient ride.
