Understanding the Super Deluxe Coil Ultimate Rear Shock
The Super Deluxe Coil Ultimate rear shock is a high-performance shock designed for aggressive trail and enduro riding. It uses a coil spring instead of air, providing a more consistent and predictable feel. The Ultimate version comes equipped with the Charger 2.1 damper for precise adjustments to compression and rebound. Rebuilding this shock at home is a great way to extend its lifespan and maintain its performance.
Step-by-Step Guide to Rebuilding Your Super Deluxe Coil Ultimate
1. Remove the Shock from the Bike
Start by carefully removing the shock from your bike. Use a 10mm socket wrench and a torque wrench [paid link] to safely remove the bolts securing the shock to the frame. Make sure to note the orientation of the shock on the bike for easy reinstallation later.
2. Clean the Shock
Before starting the rebuild process, clean the shock thoroughly. Use a clean cloth and isopropyl alcohol or shock oil cleaner to wipe off any dirt, grime, or oil. This ensures that no contaminants will enter the shock during the rebuild process.
3. Remove the Coil Spring
To access the internals of the shock, you need to remove the coil spring. Use the 8mm hex wrench to remove the spring preload collar, then slide the coil spring off the shock body. Be sure to handle the spring carefully to avoid any damage.
4. Disassemble the Damper Cartridge
To rebuild the damper, you need to disassemble the damper cartridge. Use a T10 Torx driver to remove the damper rebound adjuster and the compression knob. You may need to use the C-clip pliers to remove any retaining clips that hold components in place. Take note of the order and orientation of each part to aid reassembly.
5. Drain and Clean the Oil
Once the damper cartridge is disassembled, drain the oil from the shock body and damper. Inspect the oil for any contaminants or signs of wear. Clean the damper and shock body thoroughly using isopropyl alcohol, and ensure that no residual oil remains.
6. Replace Seals and O-rings
Inspect the seals and O-rings for wear or damage. If necessary, replace them with new seals designed specifically for the Super Deluxe Coil Ultimate. Apply a light coat of seal grease to the new seals to ensure smooth operation and to prevent leaks.
7. Rebuild the Damper Cartridge
Once the seals are replaced and the shock is cleaned, it’s time to rebuild the damper cartridge. Carefully install the components back into the shock body in the reverse order of disassembly. Ensure that everything is tightened to the correct torque specifications (typically provided by RockShox in the user manual). Pay special attention to the rebound and compression adjusters as you reinstall them.
8. Refill the Shock with Oil
Once the damper is rebuilt, refill the shock with fresh suspension fluid. For the Super Deluxe Coil Ultimate, RockShox recommends using their suspension fluid, such as SUS 0.5 or another compatible fluid. Make sure to fill the shock body to the correct oil level specified in the manual.
9. Reinstall the Coil Spring
Now that the damper and shock body are rebuilt and filled with fluid, it’s time to reinstall the coil spring. Slide the coil back onto the shock body and secure it with the preload collar. Tighten it carefully with the 8mm hex wrench, making sure to set the preload to your desired setting.
10. Reassemble the Shock
With the damper and coil spring fully reassembled, it’s time to put the shock back together. Reinstall any components you removed, such as the rebound adjuster, compression knob, and any clips or fasteners. Ensure that each component is securely tightened.
11. Perform a Test Run
Before reinstalling the shock on your bike, it’s important to perform a quick test run. Use a shock pump to pressurize the shock to the recommended PSI (usually indicated on the shock body or the manual). Check for smooth operation of the rebound and compression settings. If everything feels smooth and functions properly, the rebuild is complete.
12. Reinstall the Shock on Your Bike
Once the shock is tested and functioning properly, carefully reinstall it onto your bike. Tighten the mounting bolts to the manufacturer’s recommended torque specifications to ensure the shock is securely attached.
Troubleshooting Common Issues
1. Leaking Oil
If you notice that oil is leaking from the shock, this could be due to damaged seals or improperly tightened components. Double-check the seals and O-rings during the rebuild process and replace them if necessary.
2. Insufficient Rebound or Compression Adjustment
If you find that the rebound or compression adjustments are not working correctly, it could be due to incorrect oil levels or issues with the damper cartridge. Ensure the oil was replaced to the correct level and that all components are properly installed.
3. Coil Spring Preload Issues
If the coil spring preload is not functioning properly, check the preload collar for any damage. If the collar is not securely tightened or is worn, replace it to ensure proper tension on the coil spring.
Customization and Optimization for Better Performance
Customizing your Super Deluxe Coil Ultimate rear shock can enhance your riding experience. Consider experimenting with different spring rates based on your weight and riding style. You can also adjust the compression and rebound settings to fine-tune your shock’s performance for various terrain types.
Another way to optimize performance is by adjusting the shock’s oil levels and viscosity. Lighter oil will give a more responsive feel, while heavier oil will provide better damping for aggressive riding.
Comparing the Super Deluxe Coil Ultimate with Other Rear Shocks
When comparing the Super Deluxe Coil Ultimate to other rear shocks, consider factors like adjustability, weight, and intended use. Other high-end shocks in the market may offer similar features, but the Super Deluxe Coil Ultimate stands out with its precise adjustability, smooth performance, and coil spring design. For riders who prefer a coil shock for its consistency over air shocks, the Super Deluxe Coil Ultimate is a top-tier choice.
Compatibility with Other Drivetrain Components
The Super Deluxe Coil Ultimate rear shock is designed to work seamlessly with modern mountain bike drivetrains. It can be paired with a wide range of suspension forks and frames, but it is essential to ensure that your frame has the proper shock mount dimensions and travel compatibility. Additionally, make sure that the coil spring is suitable for your rider weight and intended usage.
Rebuilding and maintaining your Super Deluxe Coil Ultimate rear shock will ensure it remains in top condition, providing you with optimal performance on your rides. Whether you’re a seasoned mechanic or a DIY enthusiast, following these steps will help you keep your shock performing like new.
