Installation of the Super Deluxe Ultimate RCT
Installing the Super Deluxe Ultimate RCT rear shock on your mountain bike requires attention to detail to ensure proper fitment and performance. Here’s a step-by-step guide to properly install this shock.
- Remove the Existing Shock
If replacing an old shock, begin by using a 5mm Allen wrench to remove the mounting bolts securing the existing shock to the frame. Keep track of any hardware, such as washers or spacers, as you will need them for the new shock. - Prepare the New Shock
Before installation, check the Super Deluxe Ultimate RCT shock for any visible damage and ensure it has been properly lubricated at the mounting points. Apply a small amount of grease to the mounting hardware to prevent corrosion and ease future removal. - Install the Shock
Position the Super Deluxe Ultimate RCT in the shock mounts of the frame. Ensure the shock is aligned properly with the mount holes on both ends of the shock. Insert the mounting bolts and tighten them with a 5mm Allen wrench. Make sure to torque them to the manufacturer’s recommended settings for a secure fit. - Set the Sag and Adjust the Air Pressure
Use a shock pump to adjust the air pressure according to your body weight and riding style. Typically, aim for 25-30% of the shock’s travel to be used for sag, which ensures proper suspension performance. Follow the shock’s manual for precise air pressure settings. - Fine-Tune the Rebound and Compression Damping
Once the shock is installed, adjust the rebound and compression settings to match your riding conditions. Start with the default settings provided in the manual and experiment with different levels of damping to achieve the best feel for your bike setup.
Adjusting the Super Deluxe Ultimate RCT
Adjusting the Super Deluxe Ultimate RCT is critical to optimizing its performance. Fine-tuning the compression and rebound damping settings will significantly impact the bike’s handling and ride comfort.
Rebound Damping
Rebound damping controls the speed at which the shock extends after compression. Proper rebound adjustment helps prevent the rear end from bouncing excessively after hitting a bump or obstacle.
- To Adjust Rebound Damping:
- Locate the rebound adjuster dial at the bottom of the shock body.
- Turn the dial clockwise to increase damping (slower rebound) and counterclockwise to decrease damping (faster rebound).
- Test the rebound after each adjustment to ensure the shock returns smoothly without causing an unstable ride.
Compression Damping
Compression damping controls how the shock reacts under compression. This setting is crucial for preventing bottoming out when riding on rough trails or during aggressive descents.
- To Adjust Compression Damping:
- Find the low-speed compression adjuster on the shock.
- Turn the dial clockwise to increase compression damping (firmer feel) or counterclockwise to decrease damping (softer feel).
- Start with moderate settings and adjust based on your trail conditions. For aggressive riding, a firmer compression may be preferred to prevent excessive bottoming out.
Maintenance of the Super Deluxe Ultimate RCT
Maintaining the Super Deluxe Ultimate RCT rear shock is essential to ensuring it continues to perform optimally for years. Regular cleaning, servicing, and adjustments will extend the life of the shock and keep it performing at its peak.
Cleaning the Shock
- Use a soft cloth to wipe down the shock after each ride, removing dirt and debris that may accumulate on the shock body and seals.
- Use a small brush to clean out any dirt from around the shock mount area.
- Regular cleaning helps maintain smooth operation and prevents premature wear on the shock’s seals and moving parts.
Rebuilding and Servicing the Shock
For long-term performance, consider a full shock service every 50-100 hours of riding, depending on trail conditions. A service typically includes oil changes, replacing seals, and inspecting internal components for wear.
- To Service the Shock:
- Remove the shock from the bike using the same steps as the installation.
- Disassemble the shock as per the manufacturer’s instructions.
- Clean the internal parts, replace worn seals, and refill the shock with the appropriate oil.
- Reassemble the shock and reinstall it on the bike.
Troubleshooting Common Set-Up Issues
While the Super Deluxe Ultimate RCT is a high-performance rear shock, issues may arise during setup or regular use. Here are some common issues and troubleshooting steps:
The Shock is Bottoming Out
- Possible Causes: Incorrect air pressure, too little compression damping, or incorrect sag settings.
- Solution: Adjust the air pressure to increase sag, or increase the low-speed compression to firm up the shock. If the issue persists, consider reducing your weight bias during aggressive riding.
The Shock is Too Firm
- Possible Causes: High compression damping or too much air pressure.
- Solution: Decrease the compression damping or reduce the air pressure slightly to soften the shock for a more comfortable ride.
Rebound is Too Fast or Too Slow
- Possible Causes: Incorrect rebound setting or worn-out rebound valving.
- Solution: Adjust the rebound setting by turning the rebound adjuster dial. If the shock feels excessively fast or slow, perform a service to check for internal wear.
Customization and Optimization for Better Performance
The Super Deluxe Ultimate RCT offers several customization options to match your specific riding style and conditions. Here are some tips for optimizing performance:
- Adjust Air Pressure Based on Terrain: For technical trails with lots of drops and rough terrain, slightly increasing air pressure can prevent bottoming out. For smoother trails, lower air pressure may enhance comfort.
- Tuning Rebound and Compression for Climbing and Descending: On long climbs, consider firming up the compression damping to prevent excessive bobbing. On descents, soften the settings for better traction and control.
- Use Volume Spacers: Volume spacers help adjust the shock’s progression. Adding spacers can make the shock firmer in the mid-to-end stroke, preventing bottoming out, while removing them can make the shock more active and responsive.
Comparison with Similar Models
While the Super Deluxe Ultimate RCT stands out with its precise damping adjustments and excellent performance, it’s important to consider how it compares with other rear shocks on the market.
- Fox Float X2: The Fox Float X2 offers similar damping adjustments and is highly regarded for its smooth performance and versatility. However, the Super Deluxe Ultimate RCT tends to offer slightly more refined tuning, especially in rebound control.
- DVO Jade X: Known for its high level of customization, the DVO Jade X is another strong contender. While it excels in providing a plush feel, the Super Deluxe Ultimate RCT is often considered superior for aggressive riders seeking a more responsive shock.
Compatibility with Other Drivetrain Components
The Super Deluxe Ultimate RCT rear shock is compatible with a wide range of mountain bike frames, including those designed for advanced trail riding and enduro bikes. However, it is essential to confirm the shock size and mounting hardware compatibility with your frame before installation. It is also crucial to ensure that your frame supports the desired amount of travel and that the shock’s damping settings complement the suspension geometry of your bike.
The Super Deluxe Ultimate RCT pairs well with modern drivetrains from brands like Shimano and SRAM, offering a balanced ride that enhances the performance of the entire system. However, ensure that your frame can accommodate the shock’s required stroke length and that the overall weight balance is optimized for your riding style.
