  • Suspension grease
  • 10mm socket wrench
  • Suspension-specific shock pump

Step-by-Step Installation:

  1. Remove the Existing Shock: If you are replacing an old shock, begin by removing it from your frame using the appropriate tools. Be sure to carefully loosen and remove the mounting bolts and remove the shock from its mounts.
  2. Prepare the Float X E-MTB Shock: Before installing the new shock, apply a light layer of suspension grease to the mounting hardware to ensure smooth installation and prevent creaks.
  3. Align the Shock Mounts: Place the Float X E-MTB shock onto the bike frame, aligning the mounting hardware with the shock’s eyelets. Ensure the shock is properly positioned to prevent any damage to the frame or the shock during installation.
  4. Tighten the Mounting Bolts: Using the appropriate torque wrench [paid link], tighten the mounting bolts to the manufacturer’s recommended torque setting to ensure the shock is securely fastened. Over-tightening can cause damage to the shock, while under-tightening can lead to instability.
  5. Check the Shock Position: After securing the shock, double-check its position to ensure it is seated correctly in the frame. There should be no side-to-side movement or excessive play.
  6. Set Initial Air Pressure: Use a suspension-specific shock pump to set the correct air pressure based on your weight and riding style. Refer to the manufacturer’s recommendations for air pressure guidelines.
  7. Test the Shock: After installation, compress the shock several times to ensure it is functioning correctly. Make any necessary adjustments to the rebound or compression settings.

Adjustment and Tuning of the Float X E-MTB Rear Shock

The Fox Float X E-MTB rear shock is equipped with several adjustments that can be fine-tuned for optimal performance. These adjustments are crucial for tailoring the shock to your specific riding style and terrain.

Compression Adjustment

  • The compression adjustment controls how the shock reacts to impacts and large hits. For smoother trails and climbs, consider reducing compression for better traction. On rougher terrain, increasing compression will provide more support and reduce bottoming out.

Rebound Adjustment

  • Rebound adjustment determines how quickly the shock returns after compressing. For a smoother ride, slower rebound settings are ideal, particularly for rough and rocky terrain. On faster trails, faster rebound may be more appropriate.

Air Spring Pressure

  • The Float X features an air spring that can be adjusted to suit your weight and riding conditions. Adjust the air pressure based on your personal preferences, but ensure you are within the recommended range to avoid damaging the shock.

EVOL Adjustment

  • The EVOL system offers additional tunability. You can adjust the size of the negative air chamber to change the shock’s sensitivity. Increasing the size can improve small-bump sensitivity, while decreasing it will give more support for larger hits.

Maintenance of the Float X E-MTB Rear Shock

Maintaining the Fox Float X E-MTB rear shock is essential to ensure long-lasting performance. Regular maintenance helps keep the shock running smoothly and prevents issues that can arise from dirt and wear.
