  • DebonAir Spring: This shock uses the DebonAir air spring system, providing a more consistent feel throughout the stroke and improving small-bump sensitivity.
  • Advanced Rebound Control: The rebound adjuster allows you to customize how quickly the shock returns to its original position, offering better control on varied terrain.
  • Customizable Fit: With a wide range of shock sizes and the ability to adjust air pressure, riders can customize the shock to their body weight and riding style.
  • Premium Materials: Built with high-end materials like a hard-anodized aluminum body and a smooth internal design, this shock promises durability and longevity.

Installation of the Super Deluxe Ultimate RCT Rear Shock

Installing the Super Deluxe Ultimate RCT rear shock requires a few essential tools and attention to detail. While installation is generally straightforward, following the correct procedure ensures that your shock is properly fitted and performs at its best.

Tools Required:

Installation Steps:

  1. Remove the Old Shock: If you’re replacing an existing rear shock, first, remove the old shock by loosening the mounting bolts at both ends. Keep track of any washers or spacers that may be reused.
  2. Clean the Mounting Areas: Before installing the new shock, ensure the mounting areas on both the frame and shock are clean and free from dirt and debris.
  3. Apply Grease to Mounting Bolts: Lightly grease the mounting bolts to ensure smooth insertion and to prevent seizing over time.
  4. Insert the New Shock: Position the Super Deluxe Ultimate RCT into the frame’s shock mounts. Align the shock with the pivot points, ensuring it sits correctly.
  5. Tighten the Mounting Bolts: Using the appropriate torque settings (consult your frame’s manual), tighten the bolts at both ends of the shock. Be careful not to over-tighten, as this can damage the frame or shock.
  6. Check for Proper Clearance: Ensure that the shock moves freely without obstruction. Check that the frame and shock do not interfere with the tire or other components during compression.
  7. Set the Air Pressure: Using a suspension pump, adjust the air pressure according to your body weight and riding style. A general guideline is to start with a pressure equal to 25-30% of your body weight, but fine-tune based on your comfort and performance needs.

Adjustment and Tuning of the Super Deluxe Ultimate RCT

One of the key reasons riders trust the Super Deluxe Ultimate RCT is the ability to fine-tune the shock for various riding conditions. Proper adjustments enhance comfort, control, and performance. Here’s a breakdown of the critical adjustments and how to make them:

Air Pressure

The air pressure is one of the most important factors in shock performance. The right air pressure ensures that the shock performs efficiently and comfortably across various terrains. Adjust the air pressure based on your body weight, riding style, and the type of trail.

  • Starting Point: Use the manufacturer’s recommended air pressure or a starting point of 25-30% of your body weight.
  • Fine-Tuning: Adjust in small increments and check the sag by sitting on your bike. You want around 25-30% of the shock’s total travel to be used up by your body weight.

Rebound Adjustment

The rebound adjuster controls how quickly the shock returns after compression. A fast rebound setting can lead to instability, while a slow setting may cause the shock to feel sluggish.

  • Too Fast: If the shock returns too quickly, the bike will feel bouncy or unstable, especially on rough terrain.
  • Too Slow: If the rebound is too slow, the bike will feel “stuck” and may not fully recover during successive impacts.

To adjust, turn the rebound knob clockwise to slow down the rebound or counterclockwise to speed it up. Make gradual adjustments until the shock feels responsive yet controlled.

Compression Adjustment

The Super Deluxe Ultimate RCT features a 3-position compression adjustment: Open, Pedal, and Lock.

  • Open: This setting offers maximum suspension movement and is ideal for aggressive trails and downhill sections.
  • Pedal: Use this setting for smoother trails or when you want less suspension movement for better pedaling efficiency.
  • Lock: This setting stiffens the shock for maximum pedaling efficiency on smooth roads or long climbs.

Experiment with different settings depending on the type of terrain you’re riding. Fine-tuning compression can make a significant difference in ride quality.

Maintenance and Care of the Super Deluxe Ultimate RCT

Regular maintenance ensures the longevity and optimal performance of the Super Deluxe Ultimate RCT rear shock. Proper care will help prevent issues and ensure consistent, smooth suspension performance.

Cleaning

  • Regularly clean the shock using a soft cloth to remove dirt, mud, and debris. Avoid using harsh chemicals or abrasive materials that could damage the shock’s finish.
  • Ensure the shock’s seals are free from contaminants, which can cause wear and damage over time.

Servicing

  • Periodically check the air pressure and adjust it as needed.
  • Inspect the shock for any signs of damage or leaks.
  • Perform an annual service, including a full rebuild, to replace internal seals and oil. This helps maintain optimal damping performance.

Troubleshooting Common Setup Issues

Despite the advanced technology, riders sometimes encounter common issues with rear shocks. Here’s how to troubleshoot some of the most frequent problems with the Super Deluxe Ultimate RCT.

Sag Too High or Too Low

  • Too High: If you’re experiencing too much sag (over 30%), increase the air pressure to achieve proper sag.
  • Too Low: If sag is too low (less than 20%), reduce the air pressure.

No Rebound Control

If you notice a lack of rebound control, check the rebound adjuster and ensure it’s functioning correctly. If the rebound still feels off, there could be an issue with the internal damper, and you may need to service the shock.

Bottoming Out

If the shock bottoms out (hits full travel), increase the air pressure or adjust the compression settings. Alternatively, you might need to adjust your riding technique to avoid excessive impacts.

Comparison with Similar Models

When compared to other rear shocks in the market, the Super Deluxe Ultimate RCT offers a more refined experience, particularly for aggressive trail riders and enduro enthusiasts. Its adjustable settings, premium materials, and durable design set it apart from other shocks like the Fox Float X2 or the DVO Jade X.

  • Fox Float X2: Offers similar performance but lacks the 3-position compression adjustment, making the Super Deluxe Ultimate RCT a more versatile choice for varying terrain.
  • DVO Jade X: Known for its plush feel, but the Super Deluxe Ultimate RCT offers more customization options, allowing for finer adjustments across the full range of settings.

Compatibility with Other Drivetrain Components

The Super Deluxe Ultimate RCT rear shock is compatible with a wide range of modern mountain bike drivetrains. The shock is particularly effective when paired with high-performance components, such as SRAM or Shimano drivetrains, providing a smooth and responsive ride. When choosing your drivetrain and shock setup, always verify the shock’s eye-to-eye length and stroke to ensure compatibility with your frame.
