The ElevenSix Trunnion [paid link] rear shock by Push Industries is engineered for riders seeking superior suspension performance, offering a balance of high-end responsiveness and reliability. This guide will delve into the specifics of installing, adjusting, maintaining, and optimizing the ElevenSix Trunnion [paid link] rear shock. Additionally, we will examine its compatibility with other components and troubleshoot common issues to ensure riders get the most out of their suspension system.

Installation of the ElevenSix Trunnion Rear Shock

Installing the ElevenSix Trunnion rear shock requires a precise, step-by-step approach to ensure optimal performance. Here’s how to correctly install the shock on your bike frame:

1. Prepare the Tools and Workspace:
   Before you begin, make sure you have the appropriate tools. A clean and well-lit workspace is essential to avoid damaging any components.
2. Remove the Old Shock (if applicable):
   • If replacing an existing shock, carefully remove it using the appropriate tools, such as a torque wrench [paid link] and allen keys [paid link]. Keep the hardware from the previous shock in case you need it for the new one.
3. Align the Shock Mount:
   • The ElevenSix Trunnion shock uses a trunnion mount system. Ensure the shock’s eyelet and trunnion are properly aligned with the frame’s shock mount.
   • Position the shock so that it is facing the correct orientation based on your bike’s geometry.
4. Secure the Shock:
   • Insert the mounting bolts through the shock eyelet and trunnion. Tighten them with a torque wrench [paid link] to the recommended specifications outlined in the shock’s manual (typically around 20-25Nm for trunnion bolts).
   • Double-check that the shock is seated properly and that there is no play in the mount.
5. Reinstall the Rear Wheel (if removed):
   • If you had to remove the rear wheel to facilitate shock installation, now is the time to reinstall it. Ensure that the wheel is properly aligned and secure before moving forward.
6. Check the Installation:
   • After securing the shock, gently compress the suspension and check for any signs of misalignment or unusual movement. The shock should move smoothly without any resistance or play.

Adjustment of the ElevenSix Trunnion Rear Shock

Properly adjusting the ElevenSix Trunnion rear shock is crucial to optimize performance for your riding style and terrain. Follow these steps to adjust the shock:

Adjusting Rebound

Rebound adjustment controls the speed at which the shock returns after compression. Too fast a rebound can lead to instability, while too slow a rebound can result in poor shock performance.

1. Locate the Rebound Dial:
   • The rebound adjuster on the ElevenSix Trunnion rear shock is usually located at the bottom of the shock body. It is typically a red dial.
2. Set the Rebound to Your Preference:
   • Turn the rebound dial clockwise to slow the rebound and counterclockwise to increase the speed. A good starting point is to set the rebound to a moderate speed and then fine-tune it based on your riding conditions.

Adjusting Compression

Compression adjustment controls how the shock responds to impacts. The ElevenSix Trunnion rear shock offers both high-speed and low-speed compression adjustments.

1. Locate the Compression Dials:
   • The compression adjusters are typically found at the top of the shock. There are separate dials for low-speed and high-speed compression.
2. Set Low-Speed Compression:
   • Low-speed compression adjustment impacts the shock’s behavior on smaller impacts. Start by setting it to mid-range, and then adjust based on your preference for sensitivity versus support.
3. Set High-Speed Compression:
   • High-speed compression helps control the shock’s behavior on large impacts, such as drops. Begin with a softer setting and gradually increase the stiffness if you experience bottoming out on aggressive terrain.

Air Pressure Adjustment

The ElevenSix Trunnion shock uses air pressure to adjust the spring rate, and this must be set according to the rider’s weight and preferred feel.

1. Locate the Air Valve:
   • The air valve is located at the top of the shock. Use a shock pump to adjust the pressure.
2. Set the Air Pressure:
   • A good rule of thumb is to start with an air pressure that corresponds to your body weight, then adjust based on your ride experience. Aim for about 25-30% of the shock’s travel to be used as sag.

Maintenance of the ElevenSix Trunnion Rear Shock

To ensure longevity and peak [paid link] performance, regular maintenance is essential for the ElevenSix Trunnion rear shock. Here are the key maintenance steps to follow:

Cleaning the Shock

1. Wipe Down the Shock After Every Ride:
   • After each ride, use a clean, damp cloth to remove dirt and debris from the shock body. This prevents buildup that can affect performance.
2. Check for Leaks:
   • Regularly inspect the shock for any signs of oil leakage. If you notice any leakage, the shock may need to be serviced by a professional.

Servicing the Shock

1. Annual Servicing:
   • Push Industries recommends servicing the shock at least once a year. This includes checking the internal seals, cleaning the internals, and replacing any worn components.
2. Rebuilding the Shock:
   • Depending on use, the shock may require a full rebuild every 1-2 years. This involves disassembling the shock, cleaning the parts, and replacing the oil and seals.

Checking for Wear

1. Inspect the Bearings:
   • Check the shock mount bearings periodically for any signs of wear or play. If the bearings are loose, they should be replaced immediately to maintain smooth suspension performance.

Troubleshooting Common Set-up Issues

While the ElevenSix Trunnion rear shock is designed for high performance, it’s important to troubleshoot and address common issues that may arise:

1. Excessive Rebound Speed:
   • If the shock is bouncing too quickly, it may be due to improper rebound adjustment or low air pressure. Check and adjust both accordingly.
2. Bottoming Out:
   • If the shock bottoms out frequently, check your compression settings and air pressure. Increasing compression damping or adding more air pressure can help alleviate this issue.
3. Squeaking or Noises:
   • Squeaks or unusual noises may indicate a lack of lubrication or worn-out seals. Clean the shock thoroughly, lubricate the necessary parts, and inspect the seals for damage.
4. Sag Issues:
   • If the shock isn’t sagging correctly (too much or too little), adjust the air pressure. If sag remains inconsistent, inspect the shock for damage or a need for a rebuild.

Customization and Optimization

For riders seeking to fine-tune the ElevenSix Trunnion rear shock for optimal performance, customization options include:

1. Tuning the Compression and Rebound for Terrain:
   • Adjust your shock settings to suit the specific terrain you’ll be riding on. For technical trails, you may want a softer rebound and lower compression, while smoother trails may benefit from firmer settings.
2. Spring Rate Adjustment:
   • Customizing the air pressure allows you to modify the spring rate to suit your weight and riding style. A stiffer spring is better for aggressive riders, while a softer spring offers more sensitivity for lighter riders.
3. Upgrading to a Custom Tune:
   • Push Industries offers the option of a custom tune for the ElevenSix Trunnion shock. This ensures that your suspension is perfectly matched to your riding preferences and bike setup.

Compatibility with Other Drivetrain Components

The ElevenSix Trunnion rear shock is designed to work seamlessly with a variety of mountain bike frames and drivetrain components. However, compatibility with your bike’s frame is crucial for performance:

1. Frame Compatibility:
   • Ensure that your frame is compatible with the trunnion mount system. Some frames may require adapters to properly mount the shock.
2. Drivetrain Compatibility:
   • While the shock itself does not directly interact with the drivetrain, it’s important to maintain overall system balance. Ensure that your bike’s geometry and suspension work in harmony with the drivetrain for optimal performance.

Conclusion

The ElevenSix Trunnion rear shock by Push Industries is a high-performance component designed for riders who demand exceptional suspension. With its precise adjustability and advanced design, it provides riders with the ability to customize their ride experience. Regular maintenance, proper installation, and fine-tuning are key to maximizing its performance. By following the outlined steps for installation, adjustment, troubleshooting, and optimization, riders can ensure they get the best out of their ElevenSix Trunnion rear shock.
