Tools Required

  • 5mm and 6mm hex wrenches
  • Shock pump (compatible with RockShox valves)
  • Torque wrench [paid link] (for precise tightening)
  • Flathead screwdriver
  • Socket wrench set
  • Measuring tape or ruler (for sag measurement)
  • Fine brush or cloth for cleaning

Installation of the Super Deluxe Ultimate RCT

Installing the Super Deluxe Ultimate RCT [paid link] on your bike requires a few simple steps. This rear shock is compatible with a wide range of mountain bikes, but it’s important to check that your frame has the correct eye-to-eye length and stroke measurement. Follow these steps for installation:

  1. Remove the Old Shock:
    • Use a 5mm hex wrench to unscrew the bolts securing the current shock to the frame.
    • Carefully remove the shock from the frame, taking note of how it was installed to help with the new shock’s orientation.
  2. Install the New Super Deluxe Ultimate RCT [paid link]:
    • Position the new shock into place. Make sure the eyelets are correctly aligned with the mounting holes on the frame.
    • Tighten the bolts using a 6mm hex wrench. Use a torque wrench [paid link] to ensure they are tightened to the manufacturer’s recommended torque settings (usually 150-175 in-lb).
    • Be cautious not to overtighten, as this can damage the shock or the frame.
  3. Reinstall the Linkage (if applicable):
    • If your bike requires a linkage to be reattached, follow the same process for bolting it back into place.
    • Ensure everything is aligned and secure before proceeding.
  4. Check for Proper Fit:
    • After installation, check for any unusual noises or movement when compressing the shock. It should move smoothly with no binding or rattling.

Adjustment and Tuning of the Super Deluxe Ultimate RCT

The Super Deluxe Ultimate RCT offers numerous adjustments that can be fine-tuned to your riding style and terrain preferences. To get the most out of your shock, start with basic tuning and gradually fine-tune settings for optimal performance.

Air Pressure

Setting the correct air pressure is critical to achieving proper suspension sag. The right pressure will ensure that your shock performs well under load, providing support during aggressive riding and absorbing impacts efficiently.

  1. Set the Sag:
    • Use a shock pump to adjust the air pressure.
    • To achieve the recommended sag (usually around 25-30% of the shock’s total travel), sit on the bike in your riding position, and check the amount of travel the shock uses. Adjust air pressure accordingly.
    • Add air for less sag or release air for more sag.
  2. Check the Air Pressure Regularly:
    • Air pressure can fluctuate with temperature changes or over time. Make sure to check it before every ride to ensure optimal performance.

Rebound Adjustment

The rebound dial controls how quickly the shock returns to its original position after compression. This is important for maintaining control and stability on rough terrain.

  1. Set Rebound for Your Riding Style:
    • Start with a mid-range setting on the rebound dial (typically marked on the shock).
    • For smoother terrain or faster riding, increase rebound speed to allow the shock to return faster. For rougher terrain, decrease rebound speed to allow the shock to return slower.
    • Test the rebound by compressing the shock and letting it return. Fine-tune until the shock feels responsive but not too bouncy.

Compression Adjustment

The compression dial controls the shock’s resistance to compression when you hit bumps or drops. It helps manage the shock’s performance for different types of terrain.

  1. Adjust Low-Speed Compression:
    • Low-speed compression affects the shock’s performance during slow movements, such as pedaling or small bumps.
    • Set this dial in a position that gives you a firm, responsive ride without feeling too harsh.
  2. Adjust High-Speed Compression:
    • High-speed compression affects the shock’s response during large impacts.
    • Turn the dial to fine-tune the response. More compression will make the shock firmer, while less compression allows for a softer feel.
  3. Test and Fine-Tune:
    • Ride your bike on different terrain to assess the compression setting. Make adjustments based on your preference for support or comfort.

Troubleshooting Common Issues

Even the most well-maintained shock can develop issues. Below are some common problems with the Super Deluxe Ultimate RCT and how to resolve them.

Leaking Air

Problem: If the shock is losing air, it may not perform properly.

Solution:

  • Check the shock pump connection to ensure a tight seal when pumping.
  • Inspect the air valve for any visible damage.
  • If the leak persists, the seals may need replacement. Contact a certified technician for seal replacement.

Rebound Not Responding

Problem: If the rebound feels too slow or too fast despite adjustments, it could indicate an issue with the rebound damper.

Solution:

  • Check for any air in the rebound circuit by removing the air valve and cycling the shock several times.
  • If the issue persists, servicing the shock or replacing the rebound damper may be necessary.

Poor Performance After Adjustments

Problem: Sometimes, after making adjustments, the shock still doesn’t perform as expected.

Solution:

  • Double-check your settings. It’s easy to miss a small detail, such as the correct sag or improper compression setting.
  • Consider a full servicing, as worn-out seals or internal components may be hindering performance.

Customization and Optimization for Peak Performance

To optimize your Super Deluxe Ultimate RCT for specific riding conditions, further customization can be made to the shock’s settings. Adjustments can be tailored to enhance traction, improve pedaling efficiency, and maximize shock performance on various trail types.

  1. Adjust for Cross-Country or Downhill Riding:
    • For cross-country riders, set the air pressure higher and use a firmer compression setting to minimize movement while pedaling.
    • Downhill riders can lower the air pressure slightly for added comfort and adjust the rebound to be slightly slower to handle bigger drops and rougher terrain.
  2. Fine-Tune for Specific Trails:
    • For smooth trails, use a higher compression setting with moderate rebound. This will provide a faster response and reduce unnecessary suspension movement.
    • On technical or rocky terrain, a softer compression setting and slower rebound will help you maintain control over uneven surfaces.

Comparison with Similar Models

When comparing the Super Deluxe Ultimate RCT to similar rear shock models, a few key differences stand out. For example, the Fox Float X2 and the Cane Creek Double Barrel offer similar high-performance features but with slightly different adjustment ranges and feel.

  • Fox Float X2: Known for its plush feel, especially on larger drops. However, it tends to be less adjustable than the Super Deluxe Ultimate RCT in terms of low-speed compression.
  • Cane Creek Double Barrel: Offers dual-speed compression adjustment, which may be beneficial for riders looking for a more customized setup.

The Super Deluxe Ultimate RCT excels in fine-tuning capabilities, offering an ideal balance between comfort and control for both trail and aggressive riding. It’s particularly suited for riders who demand a high level of adjustability to match their dynamic riding styles.

Compatibility with Other Drivetrain Components

The Super Deluxe Ultimate RCT is designed to work seamlessly with most modern mountain bike drivetrains, particularly those using SRAM or Shimano groupsets. Ensure that your bike’s linkage and rear triangle are compatible with the shock’s eye-to-eye measurement and stroke length.

Before installation, check for any potential clearance issues with the frame, especially if your bike has a long travel fork or non-standard geometry. Proper setup ensures optimal suspension performance and drivetrain interaction.

With careful tuning and maintenance, your Super Deluxe Ultimate RCT will provide a smooth and controlled ride that meets the demands of any mountain biker.
