Key Features of the DBcoil IL Trunnion Rear Shock

The DBcoil IL Trunnion Rear Shock offers several advanced features that make it a top choice for serious cyclists:

  • Dual-Compartment Damper Design: This innovative feature allows for a more stable and consistent performance across various trail conditions.
  • Independent Rebound and Compression Adjustments: The shock provides separate controls for both rebound and compression, allowing for precise adjustments based on rider weight, terrain, and personal preference.
  • High- and Low-Speed Compression: With separate high- and low-speed compression damping, riders can fine-tune the shock’s response to different trail impacts.
  • Trunnion Mounting: The Trunnion design provides a lower mount interface, offering increased stiffness, which enhances performance and durability.
  • Air Spring and Coil Combination: The combination of an air spring with a coil shock provides a plush feel while retaining support for better traction and control.
  • Lightweight Build: While offering superior damping performance, the DBcoil IL Trunnion is designed to minimize weight, making it suitable for competitive riders looking for an edge on the trail.

Tools Required

Before starting the installation or maintenance of the DBcoil IL Trunnion Rear Shock, ensure you have the following tools on hand:

  • Shock pump (for air pressure adjustments)
  • 5mm Allen wrench [paid link] (for mounting bolts)
  • Torque wrench [paid link] (to ensure proper tightness of bolts)
  • Coil spring tool (if changing or adjusting the coil spring)
  • Suspension fluid (for maintenance)
  • Shock grease (for mounting hardware)
  • A soft cloth (for cleaning)

Installing the DBcoil IL Trunnion Rear Shock

Proper installation is crucial to ensure that the DBcoil IL Trunnion Rear Shock functions optimally. Follow these steps for correct installation:

  1. Prepare the Frame: Before installing the rear shock, clean the mounting points on the frame thoroughly to ensure no dirt or debris will interfere with the shock’s mounting.
  2. Install the Trunnion Mounting Hardware: Attach the mounting hardware to the trunnion mounts. The DBcoil IL Trunnion features a specific mounting design that requires correct alignment. Be sure to check for any orientation instructions that come with the shock.
  3. Position the Shock: Carefully position the shock into place on the frame. Ensure that the shock’s mounting points align perfectly with the frame’s mounting holes.
  4. Secure the Shock: Use a 5mm Allen wrench [paid link] to tighten the bolts that secure the shock. A torque wrench [paid link] should be used to tighten the bolts to the manufacturer’s recommended torque settings (usually around 10–12 Nm).
  5. Set Air Pressure: Using a shock pump, set the air pressure according to the rider’s weight and preferred suspension setup. This will help with the initial setup of the shock’s air spring.
  6. Check for Clearance: Once the shock is installed, check that there is sufficient clearance between the frame, shock, and any other components. Ensure that the shock is not bound or obstructed in any way.

Adjusting the DBcoil IL Trunnion Rear Shock

To get the best performance out of your DBcoil IL Trunnion Rear Shock, proper adjustment is key. Adjustments can be made for both compression and rebound settings:

Compression Adjustment

  • Low-Speed Compression: This adjustment affects the shock’s response to small bumps and trail chatter. For a smoother ride, reduce the low-speed compression. For more support and stiffness, increase the compression.
  • High-Speed Compression: This controls the shock’s response to bigger hits or impacts. A higher setting will help control bottom-out on big drops, while a lower setting may be preferable for smoother trails where large hits are less frequent.

Rebound Adjustment

  • Rebound Damping: Adjust the rebound to control the speed at which the shock returns to its neutral position after compressing. If the shock rebounds too quickly, it may lead to a bouncy or unstable ride. If it rebounds too slowly, it may not recover in time for the next impact.

Troubleshooting Common Set-Up Issues

While the Cane Creek DBcoil IL Trunnion Rear Shock is a highly durable and reliable piece of equipment, riders may encounter a few common issues during setup or while riding:

  • Noisy Shock: If you hear a knocking or creaking sound coming from the shock, it may be a sign that the mounting hardware is loose or not installed correctly. Double-check the torque settings of the bolts and ensure the shock is properly secured.
  • Sag Issues: If you’re experiencing too much sag or not enough sag, you may need to adjust the air pressure or the spring rate. Ensure that the air pressure matches your weight and riding style. For coil versions, swapping out the spring for a stiffer or softer one may be necessary.
  • Inconsistent Damping: If the shock feels inconsistent in its damping, it could indicate that the internal fluid has degraded or that the shock needs to be serviced. Regular maintenance and fluid changes are key to keeping the shock in top condition.

Customization and Optimization for Better Performance

To further optimize the performance of the DBcoil IL Trunnion Rear Shock, consider the following tips:

  • Fine-Tune Compression and Rebound Settings: Spend time dialing in the settings based on your riding style and terrain. Small adjustments can make a significant difference in comfort and control.
  • Upgrade to a High-Quality Coil Spring: While the standard coil spring is high-quality, upgrading to a more premium coil spring can improve the shock’s overall performance, providing better support and a smoother ride.
  • Consider a Custom Tuning Service: If you’re an experienced rider or racer, you may want to invest in a custom shock tuning service. This involves adjusting the shock to your specific weight, riding style, and preferences, optimizing its performance for your needs.

Comparison with Similar Models

The DBcoil IL Trunnion Rear Shock stands out in comparison to other rear shocks in the same category, such as the Fox DHX2 and the RockShox Super Deluxe Coil. Here are some differences to help you make an informed decision:

  • Weight: The DBcoil IL is lighter than both the DHX2 and the Super Deluxe Coil, making it a better option for riders looking to reduce bike weight without sacrificing performance.
  • Adjustability: The DBcoil IL offers more independent adjustments, including high- and low-speed compression damping, giving riders more fine-tuning capabilities.
  • Trunnion Mounting: The trunnion design of the DBcoil IL provides more stiffness and a better fit for certain frame designs, which can lead to improved handling and responsiveness.

Compatibility with Other Drivetrain Components

The DBcoil IL Trunnion Rear Shock is compatible with a wide range of mountain bike frames, but it’s crucial to ensure that the shock’s specifications match the requirements of your bike’s rear suspension system. Check the shock’s length, stroke, and mounting hardware to confirm compatibility with your frame. Additionally, ensure the shock aligns with your bike’s overall geometry and travel needs for optimal performance.
