- 8mm, 10mm, and 12mm hex wrenches
- Torque wrench [paid link] (with appropriate range for shock components)
- 2mm, 3mm, and 4mm hex keys [paid link]
- Suspension fluid
- Shock pump (compatible with Cane Creek shock pressures)
- Grease
- Soft cloth or towel
- Thread locker (optional)
Installation of DBcoil IL Trunnion
Installing the Cane Creek DBcoil IL Trunnion rear shock requires precision and care to ensure it performs optimally. The process involves proper alignment, securing the shock to the frame, and checking the fitment.
Step 1: Prepare the Bike
Start by removing the existing shock (if replacing a previous model). Secure the bike in a stand to ensure it’s stable. Make sure the frame is clean and free of debris in the shock mounting areas.
Step 2: Install the DBcoil IL Trunnion Shock
- Align the DBcoil IL Trunnion shock with the shock mount on the bike frame.
- Use the correct size mounting hardware (often 8mm or 10mm bolts, depending on your frame). If you’re using a new frame or shock, ensure the bolts fit snugly into the shock’s mounting holes.
- Insert the bolts through the shock’s mounting eyelets, making sure the shock sits flush against the frame.
- Tighten the bolts to the manufacturer’s recommended torque settings using a torque wrench [paid link] to avoid over-tightening and damaging the shock or frame.
Step 3: Adjust Air Pressure and Setup
Once the shock is installed, use a shock pump to set the appropriate air pressure according to your body weight and riding style. The DBcoil IL features a coil spring, so this step may be less critical than with air shocks, but ensuring proper setup is essential for optimal performance.
Step 4: Test for Clearance and Smooth Movement
Before finalizing the installation, check for proper clearance between the shock and frame. The shock should move smoothly through its travel without any binding or excessive friction. Adjust the mounting hardware if needed.
Adjusting the DBcoil IL Trunnion
The DBcoil IL Trunnion rear shock offers extensive adjustability, allowing riders to fine-tune suspension performance based on riding conditions and preferences. Key adjustments include the compression and rebound settings, along with the spring rate.
Compression Adjustment
The DBcoil IL features separate high and low-speed compression adjustments. These settings affect how the shock responds to impacts, rough terrain, and general ride comfort.
- High-Speed Compression: Adjust this setting for fast hits, such as landing from jumps or riding over sharp bumps. A higher setting increases resistance, preventing bottoming out, while a lower setting provides more sensitivity for rough terrain.
- Low-Speed Compression: This adjustment controls how the shock behaves under lighter, slower forces like pedaling and braking. Adjust it based on your riding style; too high a setting can make the bike feel sluggish, while too low may cause unwanted sag or bobbing.
Rebound Adjustment
Rebound damping controls how quickly the shock returns after compression. A slower rebound rate helps maintain stability on rough terrain by preventing the shock from “bouncing” back too quickly. A faster rebound rate allows for more responsive handling, ideal for smoother trails.
Spring Rate Selection
The DBcoil IL Trunnion uses a coil spring system, which must be selected based on the rider’s weight and riding conditions. The correct spring rate ensures that the shock compresses and rebounds correctly under load, improving comfort and control. Cane Creek offers a range of coil springs, allowing you to choose one that best matches your needs.
Maintenance of DBcoil IL Trunnion
Regular maintenance is critical to ensure the DBcoil IL Trunnion continues to perform at its best over time. Cane Creek’s rear shock is designed for durability, but like any high-performance suspension component, it requires periodic attention.
Cleaning and Inspection
After every ride, wipe down the shock with a soft cloth to remove dirt and debris. This prevents contaminants from wearing down the seals. Inspect the shock for any visible damage, leaks, or signs of wear on the bushings and mount points.
Servicing the Shock
To ensure long-term reliability, the shock should be serviced at least once a year, or more frequently if you’re riding in harsh conditions. The service includes replacing the seals, checking the oil levels, and inspecting the internal components for any signs of wear or damage. If you’re not experienced with servicing shocks, it’s best to have a professional mechanic handle this.
Spring and Oil Replacement
Over time, the coil spring may lose some of its tension, affecting ride quality. If this happens, it may be time to replace the spring. Similarly, the internal oil can break down, so periodic oil changes are essential for maintaining smooth shock action.
Troubleshooting Common Set-Up Issues
Sometimes, despite careful installation and adjustment, issues can arise with the DBcoil IL Trunnion rear shock. Here are some common problems and how to address them.
Shock Bottoming Out
If you experience bottoming out (the shock hitting its travel limit), consider adjusting the high-speed compression or switching to a stiffer coil spring. This will prevent the shock from compressing too much under hard hits.
Excessive Sag
If the shock feels too soft or you notice excessive sag, check the spring rate. It’s possible that the spring is too soft for your weight and riding style. In this case, a stiffer spring is recommended.
Rebound Problems
If the shock feels like it’s bouncing too much after a compression, try adjusting the rebound to a slower setting. If this doesn’t resolve the issue, the oil or seals may need servicing.
Customization and Performance Optimization
To optimize the performance of the DBcoil IL Trunnion rear shock, you can experiment with different spring rates, compression settings, and rebound adjustments. Fine-tuning the shock to match your riding style is essential for achieving maximum comfort, control, and efficiency.
Custom Spring Rate
Choosing the right spring rate is one of the most important steps in tuning your rear shock. A softer spring rate provides more comfort and is ideal for lighter riders or those tackling rough, technical terrain. A stiffer spring offers more support for heavier riders or aggressive downhill riding.
Adjust Compression for Terrain
Riders who primarily ride on smooth trails can benefit from softer compression settings, offering better comfort and sensitivity. For more aggressive riders or those tackling rocky, technical descents, stiffer compression settings prevent bottoming out and offer more control.
Comparing the DBcoil IL Trunnion with Similar Models
When compared to other rear shock options, such as the Fox DHX2 or RockShox Super Deluxe Coil, the DBcoil IL Trunnion stands out for its combination of adjustability, smoothness, and reliability. It is often considered an excellent choice for riders who prioritize a high level of fine-tuning. However, the Fox DHX2 tends to offer slightly more sophisticated damping adjustments, making it a popular choice for professional riders who require extreme customization.
The Cane Creek DBcoil IL Trunnion is an ideal choice for riders who value robust coil suspension with ample adjustability for a smooth and controlled ride. It’s especially effective for those riding in technical or varied terrain, where different settings can provide an optimal balance of comfort and control.
Compatibility with Other Drivetrain Components
The DBcoil IL Trunnion rear shock is compatible with most modern mountain bike frames that utilize a trunnion mount. Ensure that the frame’s suspension design is compatible with the shock’s mounting requirements. While the shock itself doesn’t directly impact drivetrain components, its performance can influence ride dynamics, particularly in terms of overall bike handling and suspension travel. Therefore, pairing it with high-quality drivetrain components that offer efficient power transfer will help maximize the performance of the entire bike.
