This guide delves into its installation, maintenance, troubleshooting, and optimization to ensure you get the most out of your ElevenSix Trunnion [paid link] Rear Shock.
Installation of the ElevenSix Trunnion Rear Shock
Installing the ElevenSix Trunnion Rear Shock requires attention to detail and proper setup to ensure optimal performance. Here’s a step-by-step process to guide you through the installation.
- Remove the Old Shock:
- Begin by removing the existing rear shock from your bike frame. Depending on the shock’s design, use the appropriate tools to detach it from both the upper and lower mounting points.
- Prepare the New Shock:
- Unbox your ElevenSix Trunnion Rear Shock and check that all components are included. Ensure the shock is tuned to your weight and riding style if you purchased it pre-tuned. If not, you will need to tune it yourself or consult with a technician for custom tuning.
- Install the Trunnion Mount:
- Attach the upper mount of the shock to the trunnion mount on the bike frame. Use the supplied hardware to secure it tightly, ensuring there is no movement.
- Lower Mount Installation:
- Attach the lower mount to the frame’s rear triangle. This is typically done using a bolt, ensuring that the shock is securely fastened to prevent any movement during rides.
- Check for Proper Alignment:
- After installing the shock, check for alignment. Make sure the shock is positioned correctly without any excessive angles, as this can lead to premature wear or performance issues.
- Check Compression and Rebound Settings:
- Before riding, adjust the compression and rebound settings according to your preferences or rider specifications. Fine-tuning these settings will allow you to optimize the shock’s performance for various trail conditions.
- Test the Setup:
- Conduct a quick test by compressing the shock manually and ensuring it operates smoothly. If you encounter resistance or stiffness, double-check your installation and settings.
Adjustment and Maintenance of the ElevenSix Trunnion Rear Shock
Regular maintenance and adjustments are essential to keep the ElevenSix Trunnion Rear Shock in peak [paid link] condition. Here’s a guide for both routine maintenance and tuning for performance optimization.
Routine Maintenance
- Cleaning:
- Regularly clean the shock to remove dirt, mud, and debris. Use a damp cloth and mild soap to clean the shock body, paying particular attention to the shaft and seals. Avoid using harsh chemicals, which may damage the shock’s components.
- Lubrication:
- The shock’s seals and internal components need occasional lubrication to function smoothly. Use the recommended suspension oil and apply it to the moving parts, including the shaft and seals.
- Inspect Seals:
- Inspect the seals regularly for wear and tear. Replace any worn seals to prevent contamination from dirt and moisture. Proper seal maintenance is essential for prolonging the lifespan of your shock.
- Air Pressure Checks:
- Check and adjust the air pressure in the shock regularly. Ensure the air canister is properly pressurized to suit your weight and riding conditions.
Performance Adjustments
- Rebound Damping Adjustment:
- Adjust the rebound damping to control the speed at which the shock returns to its extended position after compression. For smoother terrain, reduce the rebound damping; for rougher trails, increase it for better control.
- Compression Damping:
- Tune the compression damping to control how the shock responds to hits and bumps. Adjust the low-speed and high-speed compression settings depending on the type of terrain you ride on.
- Sag Adjustment:
- Set the sag according to your weight. Sag is the amount of suspension travel used when you are sitting on the bike. The ideal sag ensures that the shock performs optimally by offering a balanced ride without bottoming out or feeling too stiff.
Troubleshooting Common Setup Issues
The ElevenSix Trunnion Rear Shock is highly tunable, but incorrect setup or maintenance can lead to a few issues. Below are some common problems and solutions to address them:
Shock Not Performing Smoothly
- Possible Cause: Incorrect air pressure or dirty shock seals.
- Solution: Check and adjust the air pressure. Clean the shock and lubricate the seals.
Bottoming Out or Over-Compressing
- Possible Cause: Incorrect sag setting or too little compression damping.
- Solution: Adjust the sag to suit your weight and riding style. Increase the compression damping if necessary.
Excessive Rebound or Slow Return
- Possible Cause: Rebound damping set too low or too high.
- Solution: Adjust the rebound damping for a smoother return. Test different settings to find the right balance.
Noise During Compression
- Possible Cause: Contaminants or improper lubrication.
- Solution: Clean and lubricate the shock components. Inspect for damage or wear on seals.
Customization and Optimization for Better Performance
The ElevenSix Trunnion Rear Shock offers several customization options to fine-tune its performance. These include:
- Custom Tuning: The shock is highly customizable for different riding styles. Push Industries offers custom tuning services to adjust the shock’s compression and rebound characteristics, allowing you to dial in the perfect setup for your trails.
- Volume Spacers: The shock uses volume spacers to adjust the air spring curve. Adding or removing spacers can change how the shock responds to different impacts. Fitting the right number of spacers based on your weight and riding style will help achieve the best balance between comfort and control.
- Coil Spring Option: For riders looking for a more plush ride, Push Industries also offers a coil spring conversion for the ElevenSix Trunnion, which can provide better small bump sensitivity and more consistent performance under heavy loads.
Comparison with Similar Models
When comparing the ElevenSix Trunnion Rear Shock with other similar high-performance shocks on the market, a few key differences stand out:
- Versatility and Customization:
- The ElevenSix Trunnion offers more adjustability and tunability than many other rear shocks in its category. Its custom tuning and volume spacer options make it ideal for riders looking for precise performance.
- Durability:
- While other shocks may focus more on lightweight design, the ElevenSix is built with durability in mind. Its robust construction ensures longevity even under the most demanding riding conditions.
- Price Point:
- The ElevenSix Trunnion is positioned as a high-end rear shock, and it often comes at a premium price compared to other models. However, its performance and tuning flexibility justify the cost for serious riders who demand the best.
Compatibility with Other Drivetrain Components
The ElevenSix Trunnion Rear Shock is compatible with a wide range of mountain bike frames, especially those designed to accommodate trunnion-style mounts. However, there are a few things to consider when ensuring compatibility with your drivetrain:
- Frame Compatibility: Check that your frame has a trunnion mount system before purchasing. Many modern mountain bike frames now support this mounting type, but it’s important to verify compatibility.
- Suspension Linkage: The linkage design of your bike frame can affect the rear shock’s performance. Ensure that your frame’s linkage is designed to work with a shock like the ElevenSix for optimal performance.
- Drivetrain Setup: While the rear shock does not directly interact with your bike’s drivetrain components, ensuring that your drivetrain is properly tuned and in good condition will prevent any excessive strain on the rear suspension during shifts and pedaling.
By paying attention to these compatibility aspects, you can ensure that your ElevenSix Trunnion Rear Shock works seamlessly with the rest of your bike’s components, resulting in a smooth, responsive ride.
