This guide will help you understand the features, benefits, and potential drawbacks of the ElevenSix Trunnion while comparing it to similar rear shock models from other top brands. We will also explore how this shock stacks up in terms of installation, customization, and performance optimization.

Overview of the ElevenSix Trunnion Rear Shock

The ElevenSix Trunnion Rear Shock is designed for riders seeking high performance in aggressive trail, enduro, and downhill riding. It’s renowned for its precise damping capabilities, progressive spring rate, and exceptional adjustability. The shock is also equipped with Push Industries’ proprietary Twin Tube Technology, providing a plush feel while ensuring control over rough terrain.

Key Features of the ElevenSix Trunnion Rear Shock:

• Trunnion Mounting System: This mount is becoming increasingly popular in the industry, providing a more rigid and compact design than traditional eyelet mounts. It enhances suspension performance by offering better stroke-to-stroke consistency and smoother motion.
• Customizable Damping Settings: With a range of adjustments including high and low-speed compression and rebound settings, the ElevenSix Trunnion allows riders to fine-tune the shock to their unique riding style and terrain.
• Hydraulic Lockout: This feature offers the ability to lock out the shock for climbing or time trial segments, which reduces energy loss and maximizes pedaling efficiency.
• Piggyback Reservoir: The piggyback design helps with heat dissipation during aggressive descents, ensuring consistent damping performance even on the roughest trails.

Installation and Setup of the ElevenSix Trunnion Rear Shock

Tools Required

• Torque wrench [paid link]
• 8mm and 10mm Allen keys [paid link]
• Grease or anti-seize compound
• Suspension fluid (if necessary)

Step-by-Step Installation Process

1. Preparation: Before installation, ensure your bike frame is compatible with a trunnion mount shock. Clean the mounting points to avoid any dirt or debris that could affect performance.
2. Remove the Old Shock: Using your 8mm Allen key, carefully unscrew and remove the existing shock from your frame. Be sure to support the rear triangle while you do this to avoid damaging any components.
3. Apply Grease: Lightly grease the shock’s mounting hardware and bushings to ensure smooth movement during the life of the shock.
4. Install the New Shock: Align the ElevenSix Trunnion Rear Shock with the trunnion mounts on your bike. Insert the mounting bolts and tighten them using the appropriate torque settings as specified by Push Industries.
5. Set the Sag: Adjust the air pressure and rebound settings to match your rider weight and riding style. Set the sag by measuring the shock’s travel when the rider is on the bike in their riding position.
6. Test the Shock: Once the shock is securely mounted and set up, perform a short test ride to check for proper function. Pay attention to damping response, ride comfort, and any unusual noises or movements.

Common Setup Issues and Troubleshooting

While the ElevenSix Trunnion Rear Shock is known for its superior performance, there are a few common issues that can arise during setup or use:

• Air Spring Leaks: If you experience a drop in air pressure, inspect the shock for leaks. Ensure that the air valve is securely tightened and check for any visible damage.
• Poor Rebound Performance: If the shock rebounds too quickly or too slowly, adjust the rebound dial to fine-tune the response. It may take a few rides to get the perfect setting.
• Overheating: On long descents or aggressive riding, the shock can overheat and result in loss of performance. Ensure that the piggyback reservoir is functioning properly, and allow the shock to cool down if needed.

Performance Optimization and Customization

One of the key advantages of the ElevenSix Trunnion Rear Shock is its customization options. Riders can adjust the damping settings and air pressure to match their riding style and terrain preferences. Some tips for optimizing performance include:

• Compression Settings: Adjust the high and low-speed compression settings depending on the terrain. For technical, rocky trails, a higher compression setting may be preferred for better control. On smoother trails, reduce the compression to get a plusher ride.
• Rebound Adjustment: Set the rebound to ensure that the shock does not “pack down” under repeated hits. A quicker rebound works best for rougher, faster descents, while a slower rebound may be preferred for more controlled, smoother riding.
• Volume Spacers: The ElevenSix Trunnion features adjustable volume spacers, which allow you to change the progression of the shock’s stroke. Adding volume spacers increases ramp-up at the end of the stroke, making the shock more progressive and better suited for heavier riders or aggressive riding.

Comparing the ElevenSix Trunnion to Competitor Models

When considering the ElevenSix Trunnion, it’s crucial to compare it with other high-end rear shocks available on the market. Popular competitors include models from brands like Fox Racing Shox, RockShox, and DVO. Below is a comparison of the ElevenSix Trunnion with a few of the key models from these brands:

Fox Float X2

• Mounting System: Similar to the ElevenSix Trunnion, the Fox Float X2 uses a trunnion mount. Both shocks provide improved performance and durability compared to traditional eyelet mounts.
• Damping Adjustments: The Float X2 also offers high and low-speed compression, along with rebound adjustment. However, the ElevenSix’s damping settings are often considered more tunable, allowing for finer adjustments.
• Customization: While both shocks are highly customizable, the ElevenSix provides additional options for volume spacers, which can make a significant difference in ride feel.

RockShox Super Deluxe Coil Ultimate

• Mounting System: The Super Deluxe Coil also offers a trunnion mount option. However, unlike the air-sprung ElevenSix, the Super Deluxe uses a coil spring, making it better suited for riders who prefer the feel of a coil shock.
• Performance: The ElevenSix Trunnion tends to provide a more consistent performance across a broader range of conditions due to its air spring and adjustable settings.
• Adjustability: The Super Deluxe Coil offers fewer adjustable settings compared to the ElevenSix, which might be a limiting factor for riders looking for highly specific setup requirements.

DVO Jade X

• Mounting System: Like the ElevenSix Trunnion, the Jade X features a trunnion mount for increased performance. However, the Jade X’s performance is often considered slightly more progressive than the ElevenSix due to its different internal valving.
• Damping System: The DVO Jade X comes with high and low-speed compression and rebound adjustments, but the ElevenSix is often viewed as more user-friendly due to its smoother and easier-to-tune damping system.
• Price: The Jade X is typically more affordable than the ElevenSix, but it comes at the cost of fewer fine-tuning options.

Compatibility with Other Drivetrain Components

The ElevenSix Trunnion Rear Shock is designed to integrate seamlessly with a wide variety of drivetrain components, including popular models from SRAM, Shimano, and other leading brands. When selecting compatible components, ensure that your bike’s rear triangle is designed for a trunnion mount, as some older frames may not be compatible with this type of shock.

Additionally, if you are running a suspension fork from a different brand, such as a Fox or RockShox fork, consider the overall suspension feel when choosing a rear shock. For instance, matching a Fox Float X2 fork with an ElevenSix Trunnion rear shock can provide a balanced and cohesive ride feel, as both are designed with similar damping characteristics.

In conclusion, the ElevenSix Trunnion Rear Shock is a high-performance shock that delivers exceptional customization, durability, and overall ride quality. While it competes strongly with other premium shocks in the market, its tunability and versatility set it apart as an excellent choice for riders seeking ultimate control and performance on challenging terrain.
