  • 5mm, 8mm Allen wrenches [paid link]
  • 15mm wrench
  • Shock pump
  • Isopropyl alcohol or bike cleaner
  • Clean rags
  • 10mm socket
  • Needle grease
  • Suspension oil (RockShox recommended)
  • Bushing press tool (if needed for replacement)
  • Shock fluid syringe
  • Protective gloves

Installation of the Super Deluxe Ultimate RCT Rear Shock

The installation process for the Super Deluxe Ultimate RCT rear shock is straightforward, but it requires attention to detail to ensure the shock functions properly and safely. Follow these steps for correct installation:

  1. Remove the Old Shock
    Begin by removing the existing rear shock from your bike frame. Use the 5mm Allen wrench [paid link] to remove the mounting bolts at the top and bottom of the shock. Keep the hardware in a safe place for reinstallation if the shock is to be reused.
  2. Clean the Mounting Area
    Thoroughly clean the shock mounting points on the frame. Any debris or dirt can compromise the shock’s ability to function properly, and it may cause unnecessary wear on the shock’s bushings.
  3. Lubricate the Shock Bushings
    Before installation, apply a thin layer of grease to the shock bushings. This will help reduce friction and prolong the life of the shock.
  4. Mount the New Shock
    Position the new Super Deluxe Ultimate RCT rear shock into the frame, aligning the mounting hardware holes. Use the 5mm Allen wrench [paid link] to tighten the mounting bolts to the manufacturer-recommended torque specification (generally 250-300 in-lbs).
  5. Check the Shock Alignment
    Ensure the shock is properly aligned within the frame, and that it moves freely without obstruction. It’s crucial that the shock’s eyelet bearings or bushings are correctly positioned to avoid unnecessary wear.
  6. Set the Air Pressure
    Using the shock pump, set the air pressure to the recommended setting based on your weight and riding style. This is crucial for proper suspension setup. RockShox recommends a specific air pressure range for each rider’s weight, which can be found in the shock’s user manual.

Adjusting the Super Deluxe Ultimate RCT Rear Shock

Proper adjustments to your shock can make a significant difference in ride quality and control. The Super Deluxe Ultimate RCT offers advanced tunability to suit different riding styles and conditions. Here’s how to adjust it:

Compression Adjustment

The Super Deluxe Ultimate RCT features a three-position compression adjustment: open, medium, and firm. These settings allow you to fine-tune how the shock behaves under different conditions:

  • Open: Ideal for downhill and rough terrain, as it allows the shock to compress and rebound freely.
  • Medium: Suitable for all-mountain or trail riding, providing a balanced response between plushness and support.
  • Firm: Best for cross-country riding or when riding on smoother terrain, offering maximum support with minimal shock compression.

Adjust the compression dial on the shock to choose your desired setting. It is recommended to start with the “Open” setting and adjust based on the terrain you’re riding.

Rebound Adjustment

Rebound control regulates the speed at which the shock returns after compression. Too fast, and the shock can be bouncy; too slow, and it can feel sluggish. To adjust:

  • Turn the rebound dial clockwise to slow down the rebound.
  • Turn the rebound dial counterclockwise to speed it up.

Begin with the factory setting and make small adjustments to find the rebound speed that feels best for your riding style.

Preventative Maintenance and Cleaning

Regular cleaning and maintenance will ensure the Super Deluxe Ultimate RCT rear shock performs at its best. Follow these steps to keep it in top shape:

  1. Clean the Shock After Each Ride
    After each ride, especially in muddy or dusty conditions, clean the shock body and mounting points using a clean rag and isopropyl alcohol or a bike cleaner. Focus on the shock’s air sleeve, making sure no dirt or debris enters the shock.
  2. Inspect the Shock for Leaks
    Periodically inspect the shock for any oil or air leaks. If you notice any oil spots around the seals or a loss of air pressure, it may indicate a seal or internal component failure.
  3. Lubricate Seals and Bushings
    Every few rides, it’s good practice to lubricate the shock seals and bushings with suspension-specific grease. This helps prevent wear and tear and ensures smooth operation.
  4. Check Air Pressure
    Over time, air can escape from the shock, causing performance to degrade. Always check the air pressure before your rides, and adjust it to your recommended level using the shock pump.

Troubleshooting Common Set-Up Issues

If you experience issues with your Super Deluxe Ultimate RCT rear shock, here are some common problems and their solutions:

Loss of Air Pressure

  • Cause: Air can slowly leak out of the shock due to worn seals or improper valve closure.
  • Solution: Inspect the air valve for damage and ensure it’s properly sealed. If the shock is losing pressure quickly, you may need to replace the seals.

Excessive Rebound or Compression

  • Cause: If the shock rebounds too quickly or is too firm, there may be an issue with the internal damper.
  • Solution: Adjust the rebound or compression settings to suit your riding conditions. If adjustments don’t resolve the issue, the shock may need servicing.

Noise from the Shock

  • Cause: Noise can come from improperly lubricated bushings or worn-out seals.
  • Solution: Clean and lubricate the bushings, and check the shock for any signs of damage. If noise persists, consult a professional mechanic for further inspection.

Customization and Optimization for Better Performance

For riders looking to fine-tune their Super Deluxe Ultimate RCT rear shock, consider adjusting the air spring pressure, rebound, and compression settings based on your specific needs:

  • For Downhill Riders: Set the compression to the “Open” setting for maximum sensitivity and adjust the rebound to a slower setting to prevent bucking on big hits.
  • For Trail Riders: Use the “Medium” compression setting for a balanced feel, and adjust the rebound to match the trail conditions.
  • For Cross-Country Riders: Use the “Firm” compression setting to reduce unnecessary travel, and adjust rebound for faster recovery on smooth trails.

Compatibility with Other Drivetrain Components

The Super Deluxe Ultimate RCT rear shock is compatible with most modern mountain bike frames that accept a shock with a standard 200mm length. However, always double-check compatibility with your bike’s frame specifications. In particular, ensure that the shock’s eyelet size and the frame’s shock mount are aligned.

Additionally, while the Super Deluxe Ultimate RCT focuses primarily on rear suspension, it works best when paired with a well-balanced drivetrain. This includes a high-quality rear derailleur, cassette, and chain that ensure smooth shifting and complement the shock’s performance, especially when riding on rough terrain.

By keeping your rear shock in top condition, adjusting it to your riding style, and addressing any issues promptly, you’ll enjoy a smoother and more comfortable ride with optimal suspension performance.
