Installation of the Super Deluxe Ultimate RC2T Rear Shock

Installing the Super Deluxe Ultimate RC2T rear shock requires precision to ensure that it operates efficiently and safely. Here’s a step-by-step guide to installing this shock on your bike.

Tools Required:

  • 5mm Allen wrench [paid link]
  • 8mm Allen wrench [paid link]
  • Torque wrench [paid link]
  • Shock pump
  • Clean rag or towel
  • Suspension grease (optional)
  • 15mm shock eyelet wrench (if necessary)

Installation Steps:

  1. Prepare the Frame: Clean the shock mounting area on your bike frame to ensure there is no dirt or debris. Apply a small amount of suspension grease to the mounting hardware if required.
  2. Remove the Old Shock (if applicable): If you are replacing an existing shock, use the 5mm and 8mm Allen wrenches [paid link] to remove the bolts securing the old shock.
  3. Position the New Shock: Align the Super Deluxe Ultimate RC2T rear shock’s eyelets with the mounting points on your frame.
  4. Attach the Shock: Insert the bolts through the shock’s eyelets and the frame’s mounting points. Tighten the bolts by hand first.
  5. Torque the Bolts: Using a torque wrench [paid link], tighten the mounting bolts to the manufacturer’s recommended specifications (usually 200-250 in-lbs).
  6. Set the Sag: Attach a shock pump to the valve and adjust the air pressure to achieve the correct sag for your rider weight and preferred suspension setup.
  7. Test the Shock: Once installed, check the shock’s movement and ensure that the linkage operates smoothly. Recheck the torque settings if necessary.

Adjustment of the Super Deluxe Ultimate RC2T Rear Shock

The Super Deluxe Ultimate RC2T rear shock is equipped with numerous features for fine-tuning your suspension performance. Here’s how to make the most of them.

Rebound and Compression Adjustments:

  1. Rebound Adjustment: Use the rebound knob located at the base of the shock to adjust the rebound damping. Turn the knob clockwise for slower rebound and counterclockwise for faster rebound. This controls how quickly the shock extends after compression, and it’s crucial for maintaining control over rough terrain.
  2. High-Speed Compression: The high-speed compression knob, also located at the base, adjusts the shock’s resistance to fast impacts. Turn it clockwise to increase compression for more stability on large drops and high-speed bumps, or counterclockwise for a softer ride over smaller obstacles.
  3. Low-Speed Compression: The low-speed compression knob controls the shock’s resistance during slower impacts, like pedaling or less aggressive bumps. Adjusting this helps with overall pedal efficiency and ride comfort.

Setting Sag:

To set the sag correctly, use a shock pump to adjust the air pressure. The sag should be approximately 25-30% of the total shock stroke length for optimal performance. This ensures that the shock operates within its designed range and provides a balance between comfort and control.

Fine-Tuning for Terrain:

  • For aggressive downhill riding, increase high-speed compression and rebound damping to prevent bottoming out and maintain control.
  • For technical trail riding, adjust the low-speed compression to help with pedal efficiency while maintaining comfort over smaller obstacles.

Maintenance of the Super Deluxe Ultimate RC2T Rear Shock

Proper maintenance is essential to keep your Super Deluxe Ultimate RC2T rear shock performing at its peak. Regular maintenance will also extend the lifespan of the shock.

Cleaning:

  • After each ride, clean the shock with a damp rag to remove dirt and grime. Pay close attention to the shock body and mounting areas to prevent dirt buildup, which could affect performance.
  • Avoid using harsh chemicals or solvents, as they can damage the shock’s seals and finish.

Lubing:

  • Periodically apply a light coat of suspension grease to the mounting hardware and eyelets. This helps prevent corrosion and ensures smooth operation.
  • Inspect the shock for any visible signs of wear, such as leaking oil or worn seals. If you notice any damage, it’s important to address it immediately to avoid further complications.

Air Pressure Checks:

  • Regularly check the air pressure in the shock to ensure that it’s within the recommended range. Over time, the air pressure may fluctuate due to temperature changes or normal use. Use a shock pump to adjust the pressure as necessary.

Internal Service:

  • Every 50-100 hours of use, consider having the shock serviced by a professional. This service typically involves oil changes, seal replacements, and general inspection to keep the shock in optimal working condition.
  • RockShox recommends having a certified technician perform a full rebuild every 200 hours of riding to ensure peak performance.

Troubleshooting Common Set-Up Issues

Even the best components can encounter issues from time to time. Here are some common problems with the Super Deluxe Ultimate RC2T rear shock and how to troubleshoot them.

Problem 1: Shock Bottoming Out

  • Cause: Incorrect air pressure or low rebound damping.
  • Solution: Check the air pressure and adjust it according to the recommended sag. Increase rebound damping if necessary to prevent the shock from extending too quickly after compression.

Problem 2: Noisy Shock

  • Cause: Dirt or debris in the shock.
  • Solution: Clean the shock thoroughly, paying special attention to the mounting area and seals. Check if the mounting bolts are torqued correctly.

Problem 3: Loss of Rebound Damping

  • Cause: Low oil levels or internal shock damage.
  • Solution: Perform an internal service on the shock. If the problem persists, consult a professional technician for a rebuild or seal replacement.

Problem 4: Reduced Suspension Performance

  • Cause: Incorrect air pressure or excessive low-speed compression.
  • Solution: Recheck the air pressure and adjust it to the proper range. Try reducing the low-speed compression for a more plush feel on rough terrain.

Customization and Optimization

The Super Deluxe Ultimate RC2T rear shock can be customized to suit various riding styles and preferences. Here are some key areas to focus on when optimizing the shock for performance.

Adjusting the Damping for Different Riding Styles:

  • Enduro Riders: Set higher compression and slower rebound to handle high-speed descents and rough terrain.
  • XC Riders: Use lower compression and quicker rebound to optimize efficiency on smoother, faster trails.

Customizing for Terrain:

  • Rocky Terrain: Increase high-speed compression for better control over rough, technical sections.
  • Flowy Trails: Opt for a softer setting with more rebound to absorb small bumps and improve comfort.

Partnering with Other Drivetrain Components:

  • The Super Deluxe Ultimate RC2T rear shock is compatible with most modern mountain bike drivetrains. Ensure the shock is paired with the correct drivetrain to maintain optimal performance. A well-matched drivetrain ensures smooth transitions and consistent power delivery on various terrains.

Comparison with Similar Models

The RockShox Super Deluxe Ultimate RC2T is a high-performance rear shock, but it’s useful to know how it compares to other shocks in the same category.

Super Deluxe Ultimate RC2T vs. Fox Float X2:

  • The Fox Float X2 also offers advanced adjustment features similar to the Super Deluxe RC2T. However, the Super Deluxe is known for its higher sensitivity and plushness, making it ideal for riders seeking more comfort and control over rough trails.
  • The Fox Float X2 tends to be stiffer and may be preferred by riders who focus on aggressive downhill racing.

Super Deluxe Ultimate RC2T vs. RockShox Monarch Plus:

  • The Monarch Plus is a more budget-friendly option from RockShox, but it lacks some of the fine-tuning features of the Super Deluxe Ultimate RC2T. Riders who prioritize precision adjustments, like high-speed and low-speed compression, will find the Super Deluxe to be a better choice.

Conclusion

The RockShox Super Deluxe Ultimate RC2T rear shock is a top-tier component for riders who demand superior performance, comfort, and adjustability. By understanding the installation, adjustment, maintenance, and troubleshooting processes, you can keep your shock performing at its peak. Additionally, optimizing the shock for your riding style and terrain will further enhance your experience, ensuring that the Super Deluxe Ultimate RC2T provides a smooth, controlled ride across the toughest trails.
