Installation of the Super Deluxe Ultimate RCT Rear Shock
Step-by-Step Installation
- Prepare the Shock
Begin by carefully removing the shock from its packaging and inspecting it for any visible defects or damage. Ensure the shock’s air can is properly secured and that no oil leakage is present. - Attach the Shock to the Frame
Using the appropriate 10mm or 12mm socket wrench, attach the shock to the bike frame. Be sure to align the shock’s eyelets with the mounting hardware. Ensure the bolts are torqued to the manufacturer’s recommended specifications to avoid any damage or improper installation. - Install the Air Valve
Use the shock pump to pressurize the shock to the recommended settings based on your rider weight and riding style. The Super Deluxe Ultimate RCT rear shock uses a high-volume air spring, so it is important to precisely adjust the pressure for optimal performance. - Check the Mounting Hardware
Ensure that the mounting hardware is tight and the shock is secured properly to the frame. Double-check the torque on all bolts to avoid any loose components during a ride.
Adjusting Your Super Deluxe Ultimate RCT Rear Shock
One of the key features of the Super Deluxe Ultimate RCT rear shock is its adjustability, which allows you to fine-tune the shock to your riding style. There are several key adjustments that you can make:
Rebound Adjustment
The rebound adjuster on the Super Deluxe Ultimate RCT allows you to control how quickly the shock returns to its original position after compression. If your bike feels too bouncy or doesn’t provide enough cushioning, adjust the rebound dial:
- Clockwise: Slows down the rebound, providing a more controlled feel.
- Counterclockwise: Increases the rebound, making the shock return faster.
Compression Adjustment
Compression adjustment helps to control how the shock behaves during compression, allowing you to tune it for different riding conditions.
- Low-Speed Compression: This adjustment helps when pedaling or during small impacts. Turning the dial clockwise increases compression, providing firmer support.
- High-Speed Compression: Affects how the shock reacts to large impacts, such as drops. Turn it clockwise for a firmer, more controlled response.
Air Pressure Settings
Proper air pressure is essential for optimal shock performance. Set the air pressure using a shock pump. The correct pressure will depend on your weight, riding style, and preference, but as a general rule:
- For lighter riders (under 150 lbs), use lower air pressure settings.
- For heavier riders (over 200 lbs), increase the pressure for better support.
Regular Maintenance and Servicing
Regular maintenance of the Super Deluxe Ultimate RCT rear shock is essential to keep it performing at its best. RockShox recommends servicing the shock at least once a year or after every 200 hours of riding, whichever comes first.
Cleaning the Shock
- Clean the Shock Body:
Wipe the shock down after each ride with a clean cloth to remove dirt and debris. This prevents the buildup of grit that can damage the shock’s internals. - Inspect for Leaks:
Check around the air can and damper for signs of leakage. If there is oil or air leakage, the seals may need replacing.
Air Can Service
Performing an air can service is an important part of maintaining your shock. Over time, dirt and oil can accumulate inside the air can, which may affect performance.
- Remove the Air Can:
Use pliers to carefully remove the air can from the shock body. Be cautious not to damage the seals or components during removal. - Clean and Lubricate:
Clean the air can with suspension oil and re-lubricate the seals before reassembling. Replacing the seals at regular intervals is also recommended to maintain optimal performance.
Damper Maintenance
The damper system controls the shock’s compression and rebound settings. Over time, the damper can become less effective as oil breaks down or leaks.
- Remove the Damper Assembly:
Using the appropriate tools, carefully remove the damper assembly from the shock body. This typically involves unscrewing the damper cap and carefully removing any internal components. - Replace the Oil and Seals:
Drain the old damper oil, clean the damper components thoroughly, and replace the seals. Use suspension oil that is specifically designed for the Super Deluxe Ultimate RCT to ensure compatibility and performance. - Reassemble the Damper:
After replacing the oil and seals, carefully reassemble the damper and ensure everything is torqued to the manufacturer’s specifications.
Troubleshooting Common Set-Up Issues
If your Super Deluxe Ultimate RCT rear shock isn’t performing as expected, there are several common issues that can usually be resolved with simple adjustments.
Issue 1: Poor Rebound Control
If the shock is either too bouncy or too sluggish, the rebound setting might need adjusting. Check the rebound knob and adjust it in small increments until you find the right balance for your ride.
Issue 2: Loss of Air Pressure
If you notice that the shock is losing air pressure, it could be due to a faulty seal. Inspect the seals around the air can and damper for any signs of wear or damage. If necessary, replace the seals to restore the shock’s performance.
Issue 3: Harsh Ride
If the ride feels too harsh, you may need to adjust the compression settings. Try reducing the high-speed compression if you are encountering harsh impacts. Alternatively, reducing the low-speed compression can improve comfort during pedaling.
Customization and Optimization for Better Performance
To further optimize the performance of your Super Deluxe Ultimate RCT rear shock, consider the following customizations:
- Upgrade the Seals: Replacing the stock seals with high-quality aftermarket options can improve the shock’s performance and longevity, especially if you ride in particularly harsh conditions.
- Experiment with Air Pressure: Adjusting the air pressure to match your weight and riding style can make a noticeable difference in overall ride comfort and performance.
- Fine-Tune Compression Settings: Experimenting with compression settings for different types of terrain can provide a more personalized ride feel. For example, reduce compression for smoother trails and increase it for rough, technical terrain.
Compatibility with Other Drivetrain Components
The Super Deluxe Ultimate RCT rear shock is compatible with a variety of frame types and drivetrain systems. However, it is important to ensure that the shock’s specifications align with your bike’s requirements. Pay attention to the shock’s mounting standards, eyelet size, and stroke length to ensure compatibility with your bike frame. If you’re using an electronic suspension system, ensure that your shock is compatible with the specific system to ensure proper integration.
