- Suspension grease
- Shock pump
- Trunnion mount hardware (specific to your bike)
- 5mm hex wrench (if needed for linkage removal)
Installation of DBcoil IL Trunnion Rear Shocks
1. Preparing the Frame
Before installing the DBcoil IL Trunnion Rear Shock, ensure that your bike’s frame is compatible with a trunnion-mount shock. This shock uses a trunnion mount system, which requires specific mounting hardware and installation procedures compared to traditional eyelet-style shocks. The first step is to verify that your frame has a trunnion mount option. If it does, you’re good to go.
2. Removing the Old Shock
If you’re replacing an existing shock, use your 5mm hex wrench to remove any linkage components that may be obstructing access to the rear shock. Carefully detach the old shock from the frame, ensuring that you don’t damage any surrounding components or bushings during removal.
3. Installing the DBcoil IL Trunnion Shock
Place the Cane Creek DBcoil IL Trunnion shock into the trunnion mount on your bike frame. Make sure the shock is aligned correctly, with the mounting holes properly lined up with the trunnion hardware. Once aligned, insert the mounting bolts through the shock and the frame. Tighten the bolts using an 8mm hex wrench, making sure to torque them to the manufacturer’s recommended specifications.
4. Securing the Mounts
Use the 10mm hex wrench to fasten any additional mounts or hardware that might be necessary for securing the shock in place. It is crucial to check that the shock is secured firmly, but not overtightened, as this can affect the shock’s performance and longevity.
5. Checking for Proper Functionality
After installation, check the overall alignment of the shock and the frame. Ensure that the shock moves freely within its mount, and there is no binding or undue resistance. You should be able to compress and extend the shock without excessive friction.
Adjustment of DBcoil IL Trunnion Rear Shocks
Setting the Sag
Proper shock setup begins with adjusting the sag, which ensures that the shock performs optimally for your weight and riding style. To set the sag on the DBcoil IL Trunnion, use a shock pump to adjust the air pressure. Cane Creek recommends a sag of around 30% for most riders, but this may vary based on personal preferences or terrain.
- Inflate the shock to the recommended air pressure (refer to your rider weight and Cane Creek’s guidelines).
- Mount your bike and, without pedaling, slowly compress the suspension by sitting down in a natural riding position.
- Check the sag by measuring the distance the shock has compressed. Adjust the pressure until you reach the desired sag percentage.
Rebound and Compression Damping
The DBcoil IL Trunnion shock offers both rebound and compression damping adjustments. These allow you to fine-tune your suspension based on riding conditions and personal preferences.
- Rebound Damping: Adjust the rebound damping to control how quickly the shock returns after compression. A slower rebound can offer more stability and control, while a faster rebound can improve responsiveness.
- Compression Damping: This adjustment controls how the shock responds to impacts. Increasing compression damping can help absorb large hits, while decreasing it provides a more plush feel for smaller bumps.
Use the dials on the shock body to fine-tune these settings to match your riding style and the terrain you encounter.
Maintenance of DBcoil IL Trunnion Rear Shocks
Regular Inspection
Routine inspection of the DBcoil IL Trunnion rear shock is essential for maintaining peak [paid link] performance. Look for signs of wear or damage such as oil leakage, dents, or bent shafts. Check the mounting bolts regularly to ensure they are still torqued correctly and that the shock is securely mounted.
Cleaning
Regular cleaning of the shock helps prevent dirt and grime from accumulating, which can interfere with its performance. Use a soft cloth or brush to wipe down the shock body after each ride. Avoid using harsh chemicals or solvents that could damage the shock’s seals.
Lubrication
Periodically lubricate the shock’s air shaft with suspension grease to maintain smooth performance. Ensure that you follow the manufacturer’s recommendations for the correct lubrication procedure and frequency.
Replacing the Oil
Cane Creek recommends servicing the oil in the shock at regular intervals, usually after every 50-100 hours of riding, depending on the conditions and type of riding you do. Replacing the oil ensures that the shock continues to perform at its best, maintaining damping consistency and shock longevity.
Troubleshooting Common Set-up Issues
Shock Not Holding Pressure
If the DBcoil IL Trunnion rear shock is not holding pressure, it could be due to a damaged seal or faulty air valve. To troubleshoot:
- Check for visible oil leaks around the shock body.
- Inspect the air valve for any damage or leakage.
- If the issue persists, consider servicing the shock or replacing the air seal.
Poor Rebound Control
If the rebound feels too slow or too fast, ensure that the rebound adjuster is set correctly. Adjust the rebound damping dial and test the shock’s return speed. If the problem persists, it may be necessary to service the shock and check the internal components.
Insufficient Compression Damping
If the shock feels too soft or bottoming out too frequently, it may be due to insufficient compression damping. Increase the compression setting slightly and test it again. If the issue remains, check the shock for internal damage or oil leaks.
Customization and Optimization for Better Performance
Tuning for Terrain
The DBcoil IL Trunnion shock is highly customizable to suit various riding styles and terrains. For aggressive downhill riders, a firmer compression and slower rebound can provide more control. For cross-country or trail riding, a softer setup with more plush compression and quicker rebound may be ideal.
Coil Spring Choices
The DBcoil IL Trunnion shock is compatible with different coil springs, allowing you to further customize the shock’s feel. A stiffer coil spring may be preferable for heavier riders or those who often ride rough terrain, while a softer spring is better for lighter riders or smoother trails.
Comparison with Similar Models
DBcoil IL vs. DBair IL
While both the DBcoil IL and DBair IL are high-performance shocks from Cane Creek, the DBcoil IL features a coil spring, offering a more consistent feel throughout the travel. The DBair IL, on the other hand, uses an air spring, which allows for more adjustability in terms of sag and damping. Riders who prioritize smoothness and consistency might prefer the DBcoil IL, while those seeking lighter weight and higher tunability may lean toward the DBair IL.
DBcoil IL vs. RockShox Super Deluxe Coil
The RockShox Super Deluxe Coil is another popular choice for rear shocks, but it may not offer the same level of customization and fine-tuning as the DBcoil IL Trunnion. While both shocks perform well on technical trails, the DBcoil IL offers more precise damping adjustments and a more plush ride due to its unique coil spring design.
Compatibility with Other Drivetrain Components
The DBcoil IL Trunnion rear shock is compatible with a wide range of frames and drivetrain components, as long as the frame is designed for a trunnion mount shock. It works well with both 1x and 2x drivetrain systems, offering optimal performance for riders who prefer precision and consistency over long rides. Make sure to check your bike’s specifications to confirm compatibility before purchasing.
