  • Allen wrenches [paid link] (5mm, 6mm)
  • Shock pump
  • Clean rags
  • Small brush
  • Cleaning solution (mild soap and water)
  • Anti-seize lubricant
  • 15mm socket wrench
  • Compression tool for shock disassembly

Installation of the Float X E-MTB Rear Shock

Installing the Float X E-MTB rear shock is a straightforward process, but it requires precision to ensure that the shock functions correctly and lasts longer.

  1. Prepare the Bike: Start by removing the rear wheel of your e-MTB to gain full access to the rear shock.
  2. Align the Shock: Position the Float X E-MTB rear shock in the correct orientation, ensuring the mounting holes align with the bike frame’s shock mounts.
  3. Install the Shock: Using an Allen wrench [paid link], insert the mounting bolts through the shock’s eyelets and secure them onto the frame. Be sure not to overtighten; use a torque wrench [paid link] for accuracy (consult the Fox manual for the correct torque specification).
  4. Connect the Air Valve: Once the shock is in place, connect the air valve to a shock pump. Inflate the shock to the recommended pressure, adjusting according to your body weight and riding style. Be sure to check the manual for Fox’s recommended pressures for different riding conditions.
  5. Check the Setup: Compress the shock to ensure smooth movement. Verify that all bolts are securely fastened, and there are no rattles or unusual sounds indicating loose parts.

Adjustments for Optimal Performance

The Float X E-MTB rear shock offers several adjustments to fine-tune its performance to your liking. These adjustments allow you to cater the shock to your riding style, whether you’re climbing, descending, or handling rough terrain.

  1. Rebound Adjustment: The rebound control knob on the shock lets you control how quickly the shock returns to its original position after compression. For fast descents, a slower rebound may help with control, while quicker rebound settings are better for climbing or when navigating technical terrain.
  2. Compression Settings: The Float X features both low-speed and high-speed compression adjusters. Adjusting the low-speed compression will affect how the shock handles slower, less aggressive movements, such as pedaling or riding on smooth surfaces. The high-speed compression controls the shock’s performance when encountering large impacts or rough terrain.
  3. Volume Spacers: To adjust the air spring curve, you can add or remove volume spacers in the shock. Adding spacers can stiffen the suspension and prevent bottoming out during aggressive riding. Experiment with different spacers to find the ideal setup for your riding conditions.

Maintenance Tips to Keep Your Float X E-MTB Rear Shock Running Smoothly

Regular maintenance is crucial for keeping your Float X E-MTB rear shock in optimal condition. Here are some simple steps to maintain the shock and prolong its lifespan:

  1. Clean the Shock Regularly: After every ride, use a clean rag to wipe off any dirt, mud, or debris from the shock. Avoid using harsh chemicals; instead, use mild soap and water. Pay special attention to the shock’s seals, as dirt can cause wear and tear.
  2. Check for Leaks: Inspect the shock’s seals regularly for any signs of oil or air leaks. Leaky seals can drastically reduce the shock’s performance and lead to costly repairs. If you notice leaks, it’s time to replace the seals or consult a professional for service.
  3. Lubricate Moving Parts: Apply a small amount of anti-seize lubricant to the mounting bolts and any moving parts of the shock. This prevents corrosion and ensures smooth operation during compression and rebound.
  4. Service the Shock Annually: Even with regular cleaning, your shock will need a full service at least once a year, especially if you ride in harsh conditions. This involves draining and replacing the fluid, replacing seals, and checking for any internal wear.

Troubleshooting Common Set-Up Issues

Sometimes, your Float X E-MTB rear shock may not be performing as expected. Here are some common issues and how to troubleshoot them:

  1. Lack of Rebound Control: If the rebound is either too fast or too slow, check the rebound adjustment dial and tweak it accordingly. If this doesn’t fix the issue, it could be a sign that the oil inside the shock is too low or contaminated, requiring a full rebuild.
  2. Shock Bottoming Out: If the shock bottoms out too easily, it could be due to incorrect air pressure or insufficient compression damping. Check the shock pressure and adjust it according to your weight and riding style. If the problem persists, consider adding volume spacers to the air spring.
  3. Unusual Noises: If you hear squeaking, knocking, or rattling noises coming from the shock, inspect the mounting bolts for tightness. Also, check for any worn seals or debris buildup around the shock’s moving parts. If no external issue is found, the internal parts of the shock may require servicing.

Customizing Your Float X E-MTB Rear Shock for Better Performance

Customization can help you fine-tune the Float X E-MTB rear shock to your specific riding style and terrain. Here are some options for optimizing its performance:

  1. Air Pressure Adjustments: As mentioned earlier, adjusting the air pressure is key to tailoring the shock’s performance. Lower air pressure gives a plusher feel for downhill riding, while higher pressure provides more support for technical climbs.
  2. Volume Spacer Modification: Adding or removing volume spacers can change the air spring curve, allowing you to adjust how the shock behaves when it’s compressed. Riders looking for a progressive feel will benefit from more volume spacers, while those who prefer a more linear feel can remove some.
  3. Fine-Tuning Compression: You can further customize the performance of your rear shock by experimenting with compression settings. For example, a firm compression setting may be beneficial for aggressive riders, while a softer setting is better for smoother riding.

Compatibility with Other Drivetrain Components

The Float X E-MTB rear shock is designed to be compatible with most e-MTB frames. However, it’s important to verify the shock’s dimensions and mounting standards before installation. Ensure that your frame supports the shock’s eyelet size, stroke length, and mounting type. Additionally, pairing the shock with other high-quality drivetrain components, such as the Fox 36 fork or a compatible dropper seat post, can help maintain optimal performance across the entire bike.

Comparison with Similar Models

When comparing the Float X E-MTB rear shock with other models, it stands out for its advanced air spring technology and precise compression and rebound adjustments. While other shocks in the same category may offer similar features, the Float X’s durability and performance in extreme conditions make it a top choice for serious e-MTB riders. Its ability to handle the increased forces from an e-MTB setup—especially on technical descents and climbs—gives it an edge over other shocks that may not be optimized for e-bike use.

In conclusion, with regular maintenance, careful adjustments, and attention to detail, you can significantly extend the life of your Float X E-MTB rear shock. By following these DIY hacks, you’ll ensure your shock continues to perform at its best for years to come, providing you with smooth and controlled rides on even the toughest terrain.
