- Cane Creek shock pump
- 5mm and 6mm Allen wrenches [paid link]
- Torque wrench [paid link]
- T25 Torx wrench [paid link]
- Flathead screwdriver

Installation of the DBcoil IL Trunnion Rear Shock
Installing the Cane Creek DBcoil IL Trunnion rear shock is a straightforward process, but it requires careful attention to detail. Follow these steps to ensure proper installation:
- Prepare the Frame and Shock
Before installation, clean the frame mounting points and the shock’s mounting hardware. Ensure the shock eyelets and trunnion mounts are free of debris. Use isopropyl alcohol to clean these surfaces thoroughly. - Attach the Trunnion Mount to the Frame
Slide the shock’s trunnion mount into the frame’s corresponding holes. This type of mounting system requires that the shock’s trunnion eyelet aligns perfectly with the frame’s mounting points. Carefully insert the bolts and tighten them using a torque wrench [paid link]. Be sure to follow the manufacturer’s torque specifications to prevent damage. - Secure the Shock to the Rear Triangle
Attach the other end of the shock to the rear triangle of your bike. Use the appropriate bolts and tighten them securely with a torque wrench. Be sure the shock sits squarely within the frame to avoid any misalignment or damage during riding. - Install the Shock Pump
Attach a shock pump to the air valve of the DBcoil IL Trunnion rear shock. Begin by inflating the shock to the recommended pressure, based on your rider weight and suspension settings. Follow the manufacturer’s guidelines for the correct sag. - Check for Leaks and Functionality
After installation, cycle the shock a few times by compressing and releasing it manually. This helps check for any signs of air leaks or poor movement. If the shock doesn’t compress or rebound smoothly, inspect the seals and check the shock’s air pressure.
Adjustment of the DBcoil IL Trunnion Rear Shock
Fine-tuning your Cane Creek DBcoil IL Trunnion rear shock allows you to dial in the performance based on your riding style and terrain. Here’s how to adjust it:
Rebound Adjustment
The rebound knob on the shock controls how quickly it returns to its extended position after compression. To adjust:
- Turn the rebound knob clockwise to slow down the rebound.
- Turn it counterclockwise to speed up the rebound.
- Start by setting it to the manufacturer’s recommended baseline, then adjust for personal preference, ensuring that the shock doesn’t bounce too quickly or feel too sluggish.
Compression Adjustment
Compression damping controls how much resistance the shock provides when compressed. The DBcoil IL features separate high-speed and low-speed compression adjustments:
- Low-Speed Compression
Adjust the low-speed compression dial to control the shock’s response during slow compressions (such as pedaling or small impacts). Turn the knob clockwise to increase resistance and counterclockwise to decrease it. - High-Speed Compression
The high-speed compression dial is meant for handling big impacts like drops or large rocks. Turning it clockwise increases compression, offering more resistance to these larger impacts.
Start with medium settings for both compression adjustments and experiment with small changes until you find the balance that suits your riding style.
Maintenance of the DBcoil IL Trunnion Rear Shock
Regular maintenance is key to keeping your DBcoil IL Trunnion rear shock functioning at its best. Follow these maintenance steps to ensure longevity:
- Clean the Shock Regularly
After every ride, clean the shock with a soft cloth to remove dirt and debris. This prevents buildup that can damage the seals and compromise performance. - Check for Leaks
Inspect the shock for any signs of oil or air leaks. If you notice a drop in air pressure or oil stains, it’s time to disassemble and replace the seals. - Lubricate the Mounting Points
Apply suspension grease to the mounting hardware to ensure smooth movement and prevent wear and tear. Clean off any excess grease to avoid attracting dirt. - Shock Oil Replacement
The shock oil needs to be replaced periodically to maintain smooth damping performance. To replace the oil, remove the shock from the bike, then carefully disassemble it using a T25 Torx wrench [paid link]. Drain the old oil and replace it with fresh suspension oil. Follow Cane Creek’s recommended oil specifications for the best results. - Inspect the Seals
Over time, the seals on the shock can wear out. Inspect them regularly for any signs of cracking or damage. If necessary, replace the seals to maintain proper function.
Troubleshooting Common Set-Up Issues
Even with the best care, your DBcoil IL Trunnion rear shock may experience some issues. Here are common problems and their solutions:
Loss of Air Pressure
If you notice a significant drop in air pressure, check for any visible damage to the shock’s seals or air valve. If the seals are compromised, the shock may need a rebuild or seal replacement.
Poor Rebound Performance
If the shock feels too slow or too fast in returning to its extended position, the rebound adjustment may need fine-tuning. If the adjustment doesn’t improve performance, inspect the internals for any signs of damage or contamination.
Clunky or Noisy Performance
If the shock produces unusual noises or feels rough during compression, it could be due to dirt or debris in the shock body. Perform a thorough cleaning and re-lubricate the mounting points. If the noise persists, the shock may need to be disassembled and serviced.
Customization and Optimization for Better Performance
To get the most out of your Cane Creek DBcoil IL Trunnion rear shock, consider the following customization tips:
- Set Proper Sag
The correct sag setting is crucial for the shock to perform optimally. Check the recommended sag for your weight and riding style, and adjust the air pressure accordingly. - Experiment with Compression Settings
Fine-tuning the compression settings can dramatically improve performance. For example, if you prefer a plush ride, set the low-speed compression to a softer setting. If you need more support on technical climbs, increase the low-speed compression to avoid excessive sag. - Adjust Rebound for Terrain
Adjust your rebound settings depending on the type of terrain you’re riding. A slower rebound is ideal for rough, rocky trails, while a faster rebound works better for smoother surfaces or aggressive riding.
Compatibility with Other Drivetrain Components
The DBcoil IL Trunnion rear shock is compatible with a wide range of modern mountain bikes. However, it is essential to check the compatibility with other drivetrain components to ensure seamless performance. Verify that your bike’s rear triangle and frame design support trunnion-mounted shocks, as this will impact how the shock is mounted and how it interacts with the rest of your drivetrain.
Frame Compatibility
Ensure that your bike frame is designed to handle the DBcoil IL Trunnion’s mounting system. The trunnion mounting system requires specific frame geometry and shock hardware, which may not be compatible with all frames.
Spring Rate and Weight Considerations
The DBcoil IL features a coil spring that comes in various spring rates. Make sure the spring rate you choose matches your weight and riding style. For heavier riders or those riding in more technical terrain, a stiffer spring might be necessary to provide better support.
Conclusion
Servicing your Cane Creek DBcoil IL Trunnion rear shock is a manageable task that can greatly extend the life and performance of your shock. By following the steps for installation, adjustment, maintenance, and troubleshooting, you can keep your shock in peak [paid link] condition without needing a mechanic. With the right care, the DBcoil IL will continue to provide outstanding performance for many miles.
