Tools Required
- 8mm and 10mm Allen wrenches [paid link]
- Torque wrench [paid link]
- Shock pump (compatible with RockShox products)
- 3mm Allen wrench [paid link]
- T15 Torx driver
- Soft cloth
- Suspension oil (RockShox recommended)
- Grease (bike-specific)
- Clean rag or paper towels
- Isopropyl alcohol (for cleaning)
- Spanner wrench for preload adjustment (if applicable)
Installation of the Deluxe Coil Ultimate Rear Shock
Installing the Deluxe Coil Ultimate Rear Shock is straightforward, but requires precision to ensure optimal function and safety.
Step 1: Remove the Old Shock
- Position your bike in a stable manner using a work stand or another solid surface.
- Use an 8mm or 10mm Allen wrench [paid link] to remove the bolts securing the existing shock to the frame.
- Carefully remove the shock from the bike frame, making sure to not damage any other components.
Step 2: Install the New Deluxe Coil Ultimate Shock
- Align the mounting hardware of the new shock with the corresponding mounts on your bike frame.
- Insert the mounting bolts through the shock eyelets and secure them loosely.
- Using a torque wrench [paid link], tighten the bolts to the manufacturer’s specified torque settings, typically 250-300 inch-pounds.
- Check for any movement or misalignment of the shock once installed. If everything is correctly aligned, tighten the bolts fully.
Step 3: Check for Clearances and Lubrication
- Ensure there is enough clearance between the shock body and the frame or linkage to avoid any rubbing.
- Apply a small amount of grease to the mounting bolts to avoid seizing over time.
Adjusting the Deluxe Coil Ultimate Rear Shock
One of the standout features of the Deluxe Coil Ultimate is its customizable settings, allowing you to adjust the shock to your riding style.
Step 1: Set Preload
Adjusting the preload is the first step in tuning your shock. The Deluxe Coil Ultimate features a coil spring, which can be adjusted to your weight and riding preferences.
- Use the spanner wrench to adjust the preload collar on the coil.
- Turn the collar clockwise to add preload, or counterclockwise to reduce it.
- Set the preload so that the shock has enough sag when you’re in your riding position—generally 25-30% sag for aggressive downhill riders.
Step 2: Adjust Compression and Rebound
The Deluxe Coil Ultimate offers both low-speed and high-speed compression adjustments, as well as rebound damping. These adjustments help you fine-tune the shock for different terrain and riding conditions.
- Compression Adjustment: Start by adjusting the low-speed compression dial, typically located on the shock body. Turn it clockwise for more compression (firmer ride) or counterclockwise for less compression (softer ride). Adjust the high-speed compression by turning the high-speed compression knob if available.
- Rebound Adjustment: Rebound damping controls the speed at which the shock returns after compression. Use the rebound adjuster to fine-tune this. Turn the knob clockwise for slower rebound (firmer return) or counterclockwise for faster rebound (softer return).
Step 3: Perform a Test Ride
After making your adjustments, take your bike for a short test ride. Make sure to monitor the shock’s behavior under different conditions. Adjust the settings further if needed based on your riding experience.
Regular Maintenance of the Deluxe Coil Ultimate Rear Shock
Routine maintenance ensures that the Deluxe Coil Ultimate performs well over the long term. Regularly servicing your shock can also help prevent any major issues from developing.
Step 1: Cleaning the Shock
After each ride, clean the shock with a soft cloth and isopropyl alcohol to remove dirt, dust, and debris. Pay special attention to the seals to ensure they are not damaged or compromised. Avoid using high-pressure water, as this can push dirt into the seals.
Step 2: Check the Oil
The Deluxe Coil Ultimate is equipped with an oil reservoir, which helps manage heat and performance. Over time, the oil can degrade or become contaminated, affecting the shock’s performance.
- Check the oil level periodically, especially if you notice a decrease in performance or a noticeable change in damping.
- Replace the oil as per the manufacturer’s guidelines—typically every 50-100 hours of riding, or more frequently for aggressive riders.
Step 3: Lubricating the Seals
Apply a light coat of suspension grease to the seals and bushings when needed. Lubrication helps reduce friction and wear. Be sure to use a grease that is specifically designed for suspension components.
Step 4: Inspecting the Coil Spring
The coil spring is a vital component of the Deluxe Coil Ultimate. Regularly check the spring for any signs of damage or wear, such as cracks, scratches, or corrosion. If the spring shows any signs of damage, replace it immediately to ensure safety and performance.
Troubleshooting Common Set-Up Issues
While the Deluxe Coil Ultimate is a high-quality shock, it is not immune to common issues that can arise during setup or use. Here are a few common problems and how to resolve them:
Problem 1: Lack of Rebound Control
If the rebound is too fast or too slow, the adjustment knob might not be set correctly.
- Solution: Adjust the rebound damping by turning the knob counterclockwise to increase the rebound speed or clockwise to slow it down. Make small adjustments and test ride in between to achieve the desired response.
Problem 2: Coil Sag Issues
If you notice that the shock sags too much or not enough, it might be due to improper preload or an incorrect coil spring rate.
- Solution: Adjust the preload collar to achieve the correct sag for your weight. If sag issues persist, consider switching to a different coil spring rate.
Problem 3: Shock Lockout Issues
If your shock isn’t locking out or staying locked out when adjusted, there may be air or oil leakage, or dirt might have contaminated the lockout mechanism.
- Solution: Disassemble the shock and inspect the lockout valve. If necessary, clean and lubricate the mechanism, or replace any damaged seals.
Customizing the Deluxe Coil Ultimate for Better Performance
The Deluxe Coil Ultimate can be finely tuned to meet your specific riding preferences, and customizing it can significantly enhance your overall performance.
Spring Rate Customization
The Deluxe Coil Ultimate allows you to select a variety of coil spring rates. Choosing the correct spring rate based on your weight, riding style, and terrain will drastically improve your comfort and bike handling. For aggressive riding, consider using a stiffer spring for better support and responsiveness.
Fine-Tuning Compression and Rebound
In addition to basic preload adjustments, you can fine-tune your compression and rebound settings for specific trails or events. For example, adjust the compression settings for more aggressive terrain, or reduce the rebound speed if you’re riding on rougher surfaces to avoid bucking.
Compatibility with Other Drivetrain Components
When selecting and maintaining your rear shock, it’s important to consider its compatibility with other drivetrain components. The Deluxe Coil Ultimate is designed to work seamlessly with a variety of high-end drivetrains, but compatibility with your bike’s frame and suspension design should always be verified before installation. Make sure the shock mount spacing is appropriate for your frame and that the shock’s travel and stroke length align with the specifications of your bike’s design.
Conclusion
Regular maintenance of your Deluxe Coil Ultimate Rear Shock ensures a smooth, responsive ride every time you hit the trails. Whether you are adjusting the shock’s settings for specific terrain, troubleshooting common issues, or customizing it for peak [paid link] performance, following these steps will help you get the most out of your shock. Keep your bike’s suspension components in top condition, and your ride will always be enjoyable and efficient.
