Installation of the Super Deluxe Ultimate RCT Rear Shock

Step-by-Step Installation Guide

1. Remove the old rear shock: Begin by removing the existing rear shock from your bike’s rear triangle. Depending on your bike, this may involve detaching the shock from the frame’s mounting hardware using a 5mm Allen wrench [paid link].
2. Prepare the new shock: Inspect the new Super Deluxe Ultimate RCT for any damage. Make sure the shock is clean and free of debris before installation. You may also want to apply a light layer of grease to the mounting bolts to ensure smooth attachment.
3. Attach the shock to the frame: Align the shock’s mounting holes with the frame’s shock mounts. Use the appropriate hardware to secure the shock in place. Tighten the bolts to the manufacturer’s recommended torque specification to prevent damage or slippage.
4. Check shock travel: Ensure the shock’s travel matches the specifications for your bike. This step helps you verify that the shock is correctly sized and positioned.
5. Install the air valve: For proper suspension adjustment, make sure the air valve is easily accessible. Set the air pressure based on your rider weight and intended riding style.

Adjustment and Fine-Tuning for Optimal Performance

The Super Deluxe Ultimate RCT provides several key adjustments to help riders achieve their ideal suspension settings. Understanding these adjustments is crucial for maximizing performance and comfort.

Air Pressure Adjustment

The shock comes equipped with an air spring, which provides customizable support. Air pressure plays a crucial role in determining the shock’s responsiveness and overall feel.

• Set the air pressure: Begin by setting the air pressure based on your body weight. The recommended air pressure is typically indicated on the shock body or in the user manual.
• Adjust for sag: Check the sag (the amount the shock compresses under your weight). A proper sag ensures the shock responds correctly to the terrain. For most riders, a sag of about 25-30% of the shock’s total travel is ideal.

Rebound Damping

Rebound damping controls how quickly the shock returns to its original position after compression. Too much rebound damping can make the ride feel harsh, while too little can cause the shock to bounce back too quickly.

• Adjust rebound: Use the rebound dial to fine-tune the shock’s return speed. Start with the setting in the middle, then adjust based on your riding conditions. For aggressive trails, a slower rebound setting might be necessary, while smoother terrain requires faster rebound for better efficiency.

Compression Damping

Compression damping controls how the shock compresses under load, such as when you hit a bump or drop. The Super Deluxe Ultimate RCT offers a high and low-speed compression adjustment to refine performance.

• High-speed compression: This setting controls how the shock handles big hits and fast impacts. Set it to a firmer setting for aggressive riding.
• Low-speed compression: Adjust this for general ride comfort and support on less aggressive terrain. For more sensitive, plush performance, reduce the low-speed compression.

Lockout Feature

The lockout feature allows you to prevent the shock from compressing during certain riding conditions, such as climbing. This makes your bike more efficient on flat ground or uphill sections.

• Use the lockout: Engage the lockout feature when climbing or riding on smooth roads. This will prevent energy loss and allow you to focus on pedaling efficiency.

Maintenance of the Super Deluxe Ultimate RCT

To keep the Super Deluxe Ultimate RCT functioning optimally, regular maintenance is essential. Proper care ensures long-lasting performance and minimizes wear on critical components.

Cleaning and Lubing

• Regular cleaning: Clean the shock body and the surrounding area after every ride. Use a soft cloth to wipe off dirt and debris. Avoid using solvents or harsh chemicals, as they can damage the shock’s finish.
• Lubrication: Apply a small amount of lubricant to the shock’s mounting hardware. This ensures smooth movement and prevents corrosion.

Air Pressure and Seals Check

• Monitor air pressure: Regularly check and adjust the air pressure to maintain the correct sag. Loss of air pressure can affect performance and comfort.
• Inspect seals: Over time, seals can wear down or become damaged. Inspect them regularly for signs of oil leaks or dirt ingress. Replace seals if necessary to maintain optimal performance.

Annual Service

• Full service: At least once a year (or after every 50-100 hours of riding), perform a full service of the shock. This includes oil changes, seal replacement, and internal inspection. A professional bike shop can assist with this service.

Troubleshooting Common Set-Up Issues

While the Super Deluxe Ultimate RCT is a high-performance shock, certain issues may arise during setup or usage. Here are some common problems and their solutions.

Insufficient Rebound

If you find that the shock is not returning fast enough, it may indicate that the rebound setting is too slow or the air pressure is too low.

• Solution: Increase the rebound speed by turning the rebound knob clockwise. If the issue persists, check the air pressure and adjust it according to your weight.

Sag Issues

If the shock seems too soft or too firm, the sag may not be set correctly. Too much sag can cause bottoming out, while too little sag can make the ride too harsh.

• Solution: Recheck the air pressure and adjust it to achieve the recommended sag range of 25-30%. You can also adjust compression settings if sag adjustments don’t resolve the issue.

Lockout Failure

If the lockout feature is not engaging or disengaging properly, it could be a sign of an issue with the damper or the lever mechanism.

• Solution: Inspect the lockout lever for damage or wear. If it is functioning improperly, a service may be required to fix or replace internal components.

Customization and Performance Optimization

The Super Deluxe Ultimate RCT allows for a significant degree of customization, enabling riders to fine-tune their suspension settings to match their individual preferences and riding style.

Adjusting for Different Riding Styles

• Aggressive Riding: For downhill and enduro riding, increase the high-speed compression and decrease the rebound damping for a more controlled ride.
• Trail Riding: For trail riders seeking a balanced performance, set the shock with a moderate amount of low-speed compression and rebound to provide a good mix of comfort and control.

Weight-Based Customization

The shock can be customized for riders of various weights by adjusting the air pressure, compression, and rebound settings. Lighter riders may need less air pressure and a more sensitive shock setup, while heavier riders may require higher pressures for optimal support.

Comparison with Similar Models

When choosing a rear shock, it’s important to compare different models based on your needs. The Super Deluxe Ultimate RCT is a premium option, but how does it stack up against other popular shocks?

• Fox Float X2: The Fox Float X2 is known for its excellent damping performance and a wide range of adjustability. While the Super Deluxe Ultimate RCT has a slightly more refined lockout system, the Float X2 is often considered a more durable option for extreme conditions.
• RockShox Deluxe Select+: A more budget-friendly option within RockShox’s lineup, the Deluxe Select+ provides great performance but lacks the fine-tuned adjustments available in the Ultimate RCT model.

Overall, the Super Deluxe Ultimate RCT stands out for its precise adjustments, lockout feature, and smooth performance on a variety of terrain types.

Understanding Compatibility with Other Drivetrain Components

The Super Deluxe Ultimate RCT is designed to work seamlessly with modern mountain bike drivetrains, including those from SRAM and Shimano. Its mounting hardware and adjustable features make it compatible with most full-suspension bikes, but it is essential to ensure that your bike’s frame and the rear shock are compatible in terms of shock size, mounting hardware, and suspension kinematics.

When considering compatibility, always check the manufacturer’s specifications for your frame and the shock to ensure a perfect fit. Additionally, the shock’s performance can be influenced by your bike’s geometry and overall suspension system, so selecting components that complement each other will provide the best results.
