Installation of Fenix AIR Rear Shocks
The installation of the Fenix AIR Rear Shock requires careful attention to detail to ensure proper fitment and optimal performance. Follow these steps to install the shock properly:
1. Prepare the Bike
Place the bike on a stable bike stand [paid link]. Ensure the bike is secure and that it remains in an upright position throughout the installation process.
2. Remove the Existing Shock
If replacing an old shock, start by removing the existing rear shock from the frame. Use the appropriate Allen wrenches [paid link] to loosen the bolts holding the shock in place. Keep these bolts for reinstallation or as backup.
3. Install the Fenix AIR Rear Shock
- Position the Fenix AIR Rear Shock in the shock mount points on the frame.
- Ensure the shock’s eyelets align with the mounting points on both the frame and the rear triangle.
- Attach and tighten the mounting bolts using a 5mm or 6mm Allen wrench [paid link]. Apply a torque wrench [paid link] to ensure the bolts are tightened to the manufacturer’s recommended torque specifications.
4. Set Air Pressure
Before the first ride, it is essential to set the correct air pressure in the shock. Use a suspension pump to adjust the air pressure based on your weight and riding style. Refer to the manufacturer’s guidelines for the appropriate pressure range.
5. Check for Proper Function
Test the rear shock by gently compressing it with your hand. Ensure smooth movement without any stiffness or excessive play. If any issues arise, check the mounting bolts and air pressure once again.
Adjustment and Tuning
The Fenix AIR Rear Shock offers several adjustment features that can be fine-tuned for different riding styles and terrain. The key adjustments include rebound, compression, and air spring settings.
Rebound Adjustment
Rebound controls how quickly the shock returns after being compressed. If the rebound is too fast, the bike will feel bouncy, while too slow will make the bike sluggish. Adjust the rebound dial to find a setting that suits your riding style. Generally, a setting that returns smoothly without excessive bouncing is optimal.
Compression Adjustment
Compression settings allow you to control the firmness of the shock during impacts and pedaling. For rough terrain, a firmer setting will prevent bottoming out, while a softer setting will provide more comfort on smoother surfaces. Experiment with the settings to find the right balance for your riding conditions.
Air Spring Pressure
Adjust the air spring pressure based on your weight. Lighter riders will require less air pressure, while heavier riders will need more to avoid bottoming out. Always refer to the manufacturer’s recommended pressure chart and adjust accordingly.
Maintenance and Care
Proper maintenance of the Fenix AIR Rear Shock ensures its longevity and optimal performance. Follow these steps for ongoing care:
Regular Cleaning
After every ride, wipe down the shock with a clean cloth to remove dirt, debris, and moisture. Make sure the shock’s seals are free of grime, as dirt buildup can cause the shock to lose efficiency.
Inspect for Leaks
Periodically check the shock for any signs of oil leaks around the seals. Leaks may indicate that the seals are worn and need replacing. If you notice oil stains, consult with a professional mechanic for seal replacement.
Check Air Pressure
Air pressure can decrease over time, especially after long rides or heavy impacts. It’s important to check and adjust the air pressure regularly, ensuring it remains at the correct level based on your weight.
Annual Servicing
Even with regular cleaning, the Fenix AIR Rear Shock requires periodic servicing. An annual service from a qualified technician ensures that internal components, such as the damper and air chamber, remain in optimal condition.
Troubleshooting Common Issues
1. Shock Not Returning Properly
If the shock does not return smoothly, it could be due to incorrect rebound settings or an issue with the air spring. Check the rebound adjustment and increase or decrease the setting as needed. If the problem persists, inspect the shock for any air leaks or internal issues.
2. Bouncy or Harsh Ride
A bouncy or harsh ride typically indicates that the rebound or compression settings need adjustment. Ensure that the settings are not too stiff, as this can result in poor performance and uncomfortable rides. Adjust the compression settings or air pressure as needed.
3. Noisy Shock
If the shock begins to make excessive noise during compression or rebound, inspect it for dirt buildup or lack of lubrication. Clean the shock and ensure that the bushings and seals are properly lubricated.
Customization and Optimization
One of the key advantages of the Fenix AIR Rear Shock is its ability to be fine-tuned to meet specific rider preferences. Here are some ways to customize and optimize the shock:
Air Pressure
Adjust the air pressure based on the type of terrain and riding style. For more aggressive mountain riding, higher air pressure will offer better bottom-out resistance, while lighter pressures will provide a smoother ride for endurance cycling.
Fine-Tuning Rebound and Compression
While factory settings may work well for most riders, fine-tuning rebound and compression settings can provide a more personalized riding experience. Experiment with small adjustments to find the perfect balance between comfort and performance.
Spring Rate Options
Consider using different spring rates if your riding style or weight demands it. The Fenix AIR Rear Shock is compatible with various spring rates, which can be swapped out to achieve better performance in specific conditions.
