The ElevenSix Trunnion [paid link] rear shock from Push Industries is renowned for its performance, customization options, and durability. Whether you’re a competitive rider or an enthusiast looking to upgrade your bike’s suspension, the ElevenSix Trunnion [paid link] provides outstanding features that cater to both seasoned riders and those new to high-performance cycling. This guide will delve into the installation, adjustment, maintenance, troubleshooting, and compatibility of this shock, along with a comparison to similar models in the market.

Installation of the ElevenSix Trunnion Rear Shock

The ElevenSix Trunnion rear shock is designed for ease of installation, but it requires careful attention to ensure optimal performance and safety.

1. Prepare Your Bike
   • Ensure your bike is on a stable workstand to allow easy access to the rear triangle and shock mount points.
   • Remove the existing shock (if replacing) by carefully detaching it from the frame.
2. Install the Trunnion Mount Shock
   • Align the shock’s trunnion mounting eyes with the frame’s corresponding mounting points.
   • Insert the bolts through the shock eyelets and tighten them to the recommended torque specifications.
   • Be sure to use a torque wrench [paid link] to prevent over-tightening, which can damage the shock or frame.
3. Recheck Alignment
   • Verify that the shock is seated properly and there is no misalignment between the shock and the frame.
4. Set the Sag
   • Adjust the shock’s air pressure according to your weight and riding style to set the correct sag. This ensures optimal suspension performance during rides.

Adjusting the ElevenSix Trunnion Rear Shock

Fine-tuning your ElevenSix Trunnion shock is crucial for maximizing its performance on the trail. The shock offers a variety of adjustments that allow riders to customize their ride.

1. Rebound Damping
   • The rebound knob allows you to control the speed at which the shock returns after compression. For aggressive riding, you may want a faster rebound to maintain better control. For smoother, less technical trails, a slower rebound may offer a more comfortable ride.
2. Compression Damping
   • The compression settings enable you to control how the shock compresses under load. The ElevenSix offers both high-speed and low-speed compression adjustments, which helps you dial in the shock for different terrains. Lower compression settings are ideal for smoother trails, while stiffer settings provide better support on rougher, more technical terrain.
3. Spring Rate
   • Choose the appropriate spring rate for your weight and riding style. The ElevenSix Trunnion is equipped with a coil spring, and Push Industries offers various spring options. A stiffer spring is typically used for heavier riders or more aggressive riding styles, while a softer spring can offer more comfort for lighter riders.
4. Volume Spacers
   • Adjust the internal shock volume with spacers to control bottom-out resistance. Adding spacers increases bottom-out resistance, while removing them softens the feel and can offer a more plush ride.

Maintaining the ElevenSix Trunnion Rear Shock

Regular maintenance is key to ensuring the longevity and performance of your ElevenSix Trunnion rear shock. Push Industries recommends performing the following steps at regular intervals:

1. Clean the Shock
   • After every ride, wipe the shock body with a clean cloth to remove dirt, debris, and moisture. Pay close attention to the mounting areas, as these can accumulate grime and affect performance.
2. Inspect for Leaks or Damage
   • Regularly check for oil leaks from the shock’s seals. Leaking oil could indicate damaged seals, which should be replaced immediately to avoid further damage to the shock.
3. Air Pressure Check
   • Ensure that the air pressure is maintained within the recommended range. Low air pressure can negatively affect shock performance, while excessive pressure can lead to harshness and potential damage.
4. Full Service
   • Push Industries recommends a full shock service every 50-100 hours of riding, depending on riding conditions. This includes disassembling the shock, cleaning the internals, and replacing worn seals and oils. Full servicing ensures the shock operates smoothly and maintains its performance over time.

Troubleshooting Common Issues with the ElevenSix Trunnion Rear Shock

While the ElevenSix Trunnion rear shock is designed for durability, like any bike component, issues can occasionally arise. Here are some common problems and how to troubleshoot them:

1. Shock Is Too Soft or Too Firm
   • Solution: Check the air pressure settings and spring rate. If the shock feels too soft, consider adding air pressure or switching to a stiffer spring. Conversely, if the shock is too firm, reduce the air pressure or choose a softer spring.
2. Rebound Is Too Fast or Too Slow
   • Solution: Adjust the rebound damping knob. Turn it clockwise to slow down the rebound or counterclockwise to speed it up. Make small adjustments and test ride after each change.
3. Leaking Oil
   • Solution: Leaking oil typically means a seal has failed. Contact Push Industries for a seal kit or send the shock in for a professional service. Do not ride the bike with a leaking shock as it can cause damage.
4. Noise or Creaking
   • Solution: Clean the shock thoroughly and check for any loose bolts or mounting hardware. If the noise persists, inspect the shock for internal damage or wear.

Customization and Optimization of the ElevenSix Trunnion Rear Shock

Customizing the ElevenSix Trunnion rear shock to match your riding style can drastically improve your performance. Here’s how to fine-tune the shock for specific conditions:

1. Adjusting for Technical Trails
   • Increase low-speed compression damping to better handle rough terrain and aggressive hits. This helps maintain control and stability on technical sections.
2. Optimizing for Cross-Country Riding
   • Use a softer spring and reduce the compression damping to allow the shock to absorb small bumps more effectively. This provides a smoother ride on less aggressive trails.
3. Maximizing Downhill Performance
   • A firmer spring combined with a higher compression setting can help support the rider during high-speed descents and harsh landings. Additionally, adjust the rebound to ensure the shock returns quickly enough to prevent bottoming out.

Comparing the ElevenSix Trunnion Rear Shock to Similar Models

When considering the ElevenSix Trunnion, it’s essential to compare it with other rear shock models available on the market. Let’s take a look at how it stacks up:

1. Fox Float X2
   • The Fox Float X2 is known for its consistent performance and multiple adjustments, similar to the ElevenSix. However, the ElevenSix offers more in-depth customization options, especially with spring choices and internal volume spacers. It is a great option for riders looking for a coil shock with advanced tuning capabilities.
2. RockShox Super Deluxe Coil
   • RockShox offers the Super Deluxe Coil shock, which is similar to the ElevenSix in terms of coil spring options. The ElevenSix Trunnion stands out with its higher-end damping and tuning options, making it more suitable for riders who demand more precise adjustments.
3. DVO Jade X
   • The DVO Jade X is a high-performance coil shock with some similar features, such as low-speed compression and rebound damping. However, the ElevenSix provides superior customization with additional spring rate options and internal spacers for better fine-tuning of the ride.

Understanding Compatibility with Other Drivetrain Components

The ElevenSix Trunnion rear shock is compatible with a variety of bike frames, particularly those designed for coil shock systems. It works well with modern full-suspension bikes that feature a trunnion mount, ensuring a seamless fit and reliable performance. Riders should ensure their frame is compatible with a trunnion mount shock before installation. Furthermore, while the ElevenSix rear shock is designed for use with high-end drivetrains, pairing it with a suspension fork of similar quality will yield the best results. This ensures that both front and rear suspension systems are balanced for optimal performance.

By carefully considering your riding style, suspension needs, and frame compatibility, the ElevenSix Trunnion can offer an unparalleled experience on the trail. With its extensive adjustment options, durability, and high-end performance, the ElevenSix Trunnion is a top choice for riders who demand precision and customization from their suspension system.
