The RockShox Super Deluxe Ultimate RCT rear shock is engineered for riders who demand the best in terms of performance, precision, and adjustability. With its high-end specifications, it’s designed to handle rough terrain while providing a smooth and controlled ride. In this guide, we will take a deep dive into its installation, maintenance, troubleshooting, optimization, and compatibility with other drivetrain components.

Installation of the Super Deluxe Ultimate RCT Rear Shock

The installation of the Super Deluxe Ultimate RCT rear shock is straightforward but requires attention to detail to ensure optimal performance.

Steps for Installation:

  1. Remove the old rear shock: If replacing an existing shock, begin by removing the old one. This typically involves unbolting the shock from both the frame and the linkage. Use a torque wrench [paid link] to ensure bolts are tightened to manufacturer specifications.
  2. Prepare the frame and shock mount: Clean the shock mounting points on the frame. Dirt or debris can cause unnecessary wear on the shock or frame.
  3. Install the Super Deluxe Ultimate RCT: Align the shock’s eyelets with the frame mounts. Insert the bolts and torque them to the recommended setting in the user manual. It’s essential to torque these bolts correctly to prevent damage and ensure the shock is securely mounted.
  4. Install the air can: If the shock has a separate air can, install it as per the instructions. Ensure that the seals are properly seated to avoid air leakage.
  5. Check the suspension linkage: After mounting the shock, check that the suspension linkage is moving freely without any binding. Proper movement ensures smooth performance of the rear shock.
  6. Set up initial air pressure: Before riding, set the air pressure according to your weight and riding style, as specified in the user manual. Use a shock pump for accuracy.

Adjustment and Tuning of the Super Deluxe Ultimate RCT Rear Shock

The Super Deluxe Ultimate RCT offers advanced tunability to cater to different riding conditions. Proper adjustment ensures maximum comfort and control.

Key Adjustments:

  1. Rebound Damping: The rebound damping controls the rate at which the shock returns to its original position after compression. Adjust it based on the terrain you’ll be riding on. For smoother trails, a faster rebound works, while rougher conditions benefit from slower rebound.
  2. Compression Damping: The compression damping is crucial for how the shock reacts to impacts. The Super Deluxe Ultimate RCT features external adjustments for both low-speed and high-speed compression, allowing fine-tuned control for different terrains.
  3. Air Spring Pressure: The air spring pressure directly affects how the shock absorbs impacts. Adjust the air pressure based on rider weight, riding style, and the type of terrain. Too much pressure results in a harsh ride, while too little will cause the shock to bottom out.
  4. Volume Spacers: The shock uses internal volume spacers to modify the air spring curve. Adding spacers can increase bottom-out resistance for bigger hits, while removing them will make the shock more progressive and allow for a smoother ride on smaller bumps.

Maintenance of the Super Deluxe Ultimate RCT Rear Shock

Regular maintenance of the Super Deluxe Ultimate RCT rear shock is critical to ensure its longevity and peak performance.

Maintenance Checklist:

  1. Clean After Rides: After every ride, especially in muddy or wet conditions, clean the shock using water and a gentle cloth. Avoid using high-pressure washers, as they can damage seals.
  2. Lubricate the Seals: Apply a light layer of suspension-specific lubricant to the seals regularly. This helps maintain smooth performance and prevents damage from dirt or debris.
  3. Check for Leaks: Routinely inspect the shock for any signs of air or oil leakage. If you notice any leaks, address them immediately to prevent further damage.
  4. Service Intervals: RockShox recommends servicing the Super Deluxe Ultimate RCT rear shock every 50-100 hours of riding, or once a year, depending on the frequency of use. The service should include a complete oil change and inspection of seals and internal parts.
  5. Seal Replacement: The seals can wear over time, reducing performance. Replace the seals according to the manufacturer’s recommended intervals to keep the shock operating at its best.

Troubleshooting Common Set-up Issues

The Super Deluxe Ultimate RCT rear shock is designed to be user-friendly, but like any high-performance component, it can encounter some issues. Here are some common problems and how to resolve them.

1. Shock Not Holding Air Pressure:

  • Possible Cause: A faulty or damaged air valve or seal.
  • Solution: Inspect the air valve for damage. If the valve appears fine, the seals may need to be replaced. Air leaks should be fixed immediately to maintain proper shock function.

2. Shock Bottoms Out Too Easily:

  • Possible Cause: Insufficient air pressure or too few volume spacers.
  • Solution: Check the air pressure and adjust it according to your weight and riding style. If the issue persists, add volume spacers to increase bottom-out resistance.

3. Rebound or Compression Damping Not Responsive:

  • Possible Cause: Damping circuit is clogged or the shock needs a service.
  • Solution: Clean the shock and ensure the damping adjustments are set correctly. If the problem persists, it may be time for a full rebuild or service to flush out any internal contaminants.

Customization and Optimization for Better Performance

Customizing the Super Deluxe Ultimate RCT to suit your riding style can significantly improve your riding experience.

Optimizing for Trail Riding:

  • Air Pressure: Lower air pressure will provide a more plush ride. For aggressive trail riding, keep the air pressure at the lower end of the recommended range for a more forgiving feel.
  • Compression Settings: Set the low-speed compression damping to allow the shock to absorb smaller hits while preventing bottoming out on larger ones.

Optimizing for Downhill Riding:

  • Air Pressure: Increase the air pressure to reduce the risk of bottoming out during high-impact descents.
  • Compression Settings: Increase the high-speed compression damping to firm up the shock for handling large hits and fast descents.

Optimizing for Cross-Country:

  • Air Pressure: Keep the air pressure higher to improve efficiency and prevent excessive sag.
  • Rebound Settings: Use a faster rebound setting to maintain stability on rough terrain while keeping the rear wheel in contact with the ground.

Comparison with Similar Models

The Super Deluxe Ultimate RCT is one of the top-tier models in the RockShox lineup, but how does it stack up against other similar shocks?

RockShox Monarch Plus:

  • Performance: The Monarch Plus is a more budget-friendly option that is great for riders looking for a more forgiving shock. However, it lacks the fine-tuning capabilities and adjustable air spring of the Super Deluxe Ultimate RCT.
  • Suitability: The Monarch Plus is ideal for trail and cross-country riding, whereas the Super Deluxe Ultimate RCT excels in downhill and aggressive trail riding with more precise adjustments.

Fox Float X2:

  • Performance: The Fox Float X2 offers a comparable performance level, featuring advanced damping adjustments and an air spring system. However, it tends to be pricier than the Super Deluxe Ultimate RCT.
  • Suitability: While both shocks are highly adjustable, the Super Deluxe Ultimate RCT might be the better option for riders seeking a more cost-effective solution without compromising on performance.

Compatibility with Other Drivetrain Components

The Super Deluxe Ultimate RCT rear shock is compatible with a wide range of modern mountain bike frames and drivetrains. It is important to ensure that the shock’s mounting system aligns with your frame and suspension configuration.

Key Compatibility Considerations:

  1. Mounting Standard: Ensure the shock is compatible with your bike’s shock mounting system, such as metric or imperial sizes.
  2. Suspension Travel: Verify the shock’s travel is suitable for your frame. Most mountain bikes with a rear shock in this class will accommodate the Super Deluxe Ultimate RCT.
  3. Linkage and Geometry: Check that the shock works within the bike’s intended suspension linkage and geometry. Incorrect alignment can lead to suboptimal performance.

By considering these factors, you can ensure the Super Deluxe Ultimate RCT integrates seamlessly with your bike’s existing drivetrain and suspension components, providing a smooth and controlled ride.
