Installation of the Super Deluxe Ultimate RC2T

Installing the Super Deluxe Ultimate RC2T requires precision to ensure proper functioning and to get the most out of your suspension. Follow these steps for a smooth installation process.

  1. Prepare the Bike
    • Ensure that your bike is clean and stable before beginning the installation.
    • Use a bike stand [paid link] to secure the bike in place.
  2. Remove the Old Shock
    • Use the correct-sized hex wrench to remove the bolts securing the old shock to the frame.
    • Carefully slide the shock out from its mounting points.
  3. Align the Super Deluxe Ultimate RC2T
    • Position the Super Deluxe Ultimate RC2T shock into the frame, aligning the shock’s eyelet with the mounting holes on the frame and the swingarm.
    • Ensure that the shock is oriented properly with respect to the frame, paying attention to the position of the damper and air canister.
  4. Secure the Shock
    • Tighten the mounting bolts with a torque wrench [paid link] to the manufacturer’s recommended specifications. This step is crucial to avoid any damage to the frame or shock.
  5. Install the Shock Hardware
    • Install any required hardware, including washers and spacers, as needed for your specific frame.
    • Ensure that the shock eyelet is properly seated to avoid any misalignment or binding during suspension travel.
  6. Check for Movement
    • After installation, check for proper movement by compressing and extending the shock. Ensure the shock moves smoothly and without resistance.

Adjustment of the Super Deluxe Ultimate RC2T

The Super Deluxe Ultimate RC2T offers extensive adjustability to fine-tune the suspension to your riding style and terrain. Key adjustments include rebound, compression, and air pressure.

Rebound Adjustment

  • The rebound knob on the RC2T controls how fast the shock returns after compression. Turning the knob clockwise will slow the rebound, while turning it counterclockwise will increase the rebound speed.
  • Adjust the rebound to match your riding conditions. A slower rebound is useful for rough, technical terrain, while faster rebound works better on smoother trails.

Compression Adjustment

  • The RC2T features a two-position compression switch: open and firm. The open position provides a more plush, active feel, ideal for rough trails. The firm position reduces travel and improves efficiency on smoother terrain.
  • Fine-tune the compression settings by adjusting the high and low-speed compression dials. These adjust the shock’s behavior during different speeds of impact. High-speed compression should be set to prevent bottoming out on large hits, while low-speed compression helps control the shock’s performance on slower, technical sections.

Air Pressure

  • Air pressure is crucial for setting the correct sag in the rear shock. Use a shock pump to add air to the shock, adjusting the pressure to match your rider weight and the amount of sag desired. The recommended sag is typically around 30% of the shock’s total travel.
  • Adjust air pressure based on your riding style. Lighter riders may need lower pressure, while heavier riders require more.

Maintenance of the Super Deluxe Ultimate RC2T

Proper maintenance is essential to keep your Super Deluxe Ultimate RC2T running smoothly for years. Regular checks and service ensure the longevity and performance of the shock.

  1. Clean the Shock
    • After every ride, clean the shock with a damp cloth to remove dirt and debris that can cause wear on the seals.
    • Use a degreaser on the shock shaft and air canister to remove any accumulated grease or grime.
  2. Check for Leaks
    • Inspect the shock for any signs of oil leaks, especially around the seals. If you notice any leaks, the seals may need replacement.
  3. Re-lubricate the Seals
    • Apply lubricant to the shock’s seals to ensure smooth performance. This prevents the seals from drying out and reduces friction.
  4. Air Pressure Checks
    • Check the air pressure regularly, as fluctuations in temperature can cause pressure changes, affecting performance. Re-adjust the pressure as necessary.
  5. Annual Service
    • Plan for a full service by a qualified technician at least once a year. During this service, the shock’s internals will be cleaned, lubricated, and the seals will be replaced if necessary.

Troubleshooting Common Set-Up Issues

Even with careful installation and adjustment, issues can arise. Here are some common problems and how to fix them.

1. Shock Bottoming Out

  • Cause: Incorrect air pressure or too low compression damping.
  • Solution: Increase air pressure to achieve the correct sag or adjust the compression settings to prevent excessive travel.

2. Harsh Ride or Lack of Plushness

  • Cause: Too much compression damping or too little air pressure.
  • Solution: Reduce the compression damping and adjust the air pressure to ensure the shock is active and responsive.

3. Poor Rebound Performance

  • Cause: Rebound setting too fast or too slow.
  • Solution: Adjust the rebound knob for a slower or faster rebound depending on the terrain and riding style.

4. Suspension Not Moving Smoothly

  • Cause: Dirt or debris in the shock or worn seals.
  • Solution: Clean the shock thoroughly and lubricate the seals. If the problem persists, consider replacing the seals.

Customization and Optimization for Better Performance

The Super Deluxe Ultimate RC2T allows for extensive customization to maximize performance. Here are a few tips to get the most out of your shock:

  • Adjust Air Pressure for Terrain: Use a lower air pressure for more grip and comfort on rough, rocky trails, and a higher air pressure for smoother rides to improve pedaling efficiency.
  • Compression Settings: Experiment with both high and low-speed compression settings to find the optimal balance between control and comfort. Fine-tuning these settings is essential when riding a variety of terrains.
  • Fine-Tune Rebound: Adjust the rebound based on the terrain you’ll be riding. For aggressive, high-speed descents, slower rebound will prevent bucking, while faster rebound can help on smoother trails.

Comparison with Similar Models

While the Super Deluxe Ultimate RC2T is a high-end shock, it is not the only option on the market. Here’s how it compares to similar models in terms of performance and features.

  • RockShox Monarch Plus RC3: The Monarch Plus is a bit more budget-friendly but offers less adjustability than the Super Deluxe RC2T. It’s a great option for riders looking for a reliable shock without the extensive fine-tuning capabilities.
  • Fox Float X2: The Fox Float X2 is another top competitor in the high-performance shock category. It features similar adjustability but tends to be a bit more expensive. The Float X2 has a more refined damping system, offering a slightly more active feel compared to the Super Deluxe RC2T.
  • Öhlins TTX Air: The Öhlins TTX Air offers premium performance with an advanced damping system. However, it may not be as user-friendly in terms of adjustability for beginners. It is a great option for expert riders who need ultimate performance in harsh conditions.

Compatibility with Other Drivetrain Components

The Super Deluxe Ultimate RC2T is designed to integrate seamlessly with most modern mountain bike frames and drivetrain systems. However, there are a few things to keep in mind when ensuring compatibility:

  • Shock Mounting: Ensure that the shock is compatible with the frame’s mounting system. The eyelet size and stroke length must match the frame’s specifications.
  • Linkage Compatibility: Some bikes may require custom linkages or adapters to ensure the shock performs optimally.
  • Drivetrain Considerations: While the shock itself doesn’t directly interact with the drivetrain, it’s important to ensure that the shock’s performance complements your riding style and the bike’s overall suspension setup.
