Installation of Super Deluxe Ultimate RC2T Rear Shock

Proper installation of the Super Deluxe Ultimate RC2T rear shock is crucial for ensuring optimal performance and safety. Follow these steps to install your rear shock correctly.

Step-by-Step Installation Process

  1. Remove the Old Rear Shock:
    • Use the appropriate tools to remove the existing rear shock from your bike. Be sure to detach the bolts at both the top and bottom mounting points. Keep track of any washers or spacers.
  2. Inspect the Mounting Points:
    • Check the mounting points on both the frame and the shock to ensure there is no damage or excessive wear. Clean these areas thoroughly before installing the new shock.
  3. Install the New Rear Shock:
    • Insert the Super Deluxe Ultimate RC2T into the frame’s shock mount. Ensure that the mounting holes align properly and that the shock is seated securely.
  4. Attach the Mounting Bolts:
    • Insert the bolts through the shock’s mounting holes and the frame. Tighten the bolts to the manufacturer’s recommended torque specification. Be cautious not to overtighten, as this could damage the components.
  5. Adjust the Sag:
    • Adjust the sag based on your rider weight and riding style. This involves setting the proper air pressure in the shock, which is crucial for achieving optimal suspension performance.
  6. Check for Proper Function:
    • After installation, compress the shock a few times to ensure it moves smoothly. Inspect the installation to confirm the shock is aligned and all bolts are properly tightened.

Adjustment and Tuning of the Super Deluxe Ultimate RC2T Rear Shock

The Super Deluxe Ultimate RC2T features multiple adjustment options that allow riders to fine-tune the suspension to their preference. These include rebound, compression, and air pressure adjustments. Here’s how to adjust each setting:

Air Pressure Adjustment

  • Goal: To set the correct sag, which determines how much the shock compresses under rider weight.
  • Procedure:
    • Use a shock pump to adjust the air pressure. RockShox provides recommended pressure ranges based on rider weight.
    • To check the sag, compress the shock while seated on the bike. A correct sag is typically around 30% of the total stroke.

Rebound Adjustment

  • Goal: To control how quickly the shock returns after compression, affecting the bike’s handling and comfort.
  • Procedure:
    • Adjust the rebound knob (typically located at the bottom of the shock) to either speed up or slow down the rebound. Start with a mid-range setting and adjust based on your preference. Slower rebound settings provide more stability, while faster settings can improve comfort.

Compression Adjustment

  • Goal: To control the shock’s response to bumps and impacts, ensuring that the shock doesn’t bottom out too easily.
  • Procedure:
    • The RC2T model features a two-position compression lever: open and firm. The open setting allows for more plush suspension, ideal for rough trails, while the firm setting helps prevent bottoming out on smooth, faster terrain.
    • Fine-tune the high-speed and low-speed compression dials to adjust the responsiveness to large hits and smaller bumps, respectively. These settings can significantly affect how the bike handles various terrain features.

Maintenance of the Super Deluxe Ultimate RC2T Rear Shock

Maintaining your Super Deluxe Ultimate RC2T rear shock is essential for long-lasting performance. Regular maintenance helps prevent damage, maintain smooth action, and ensure optimal performance over time.

Regular Inspection

  • Frequency: Every 25 to 50 hours of riding, or after each major ride.
  • Procedure: Inspect the shock for any signs of wear, oil leaks, or damage to the air canister. Clean the shock using a soft cloth and mild detergent to remove dirt and debris.

Air Spring Maintenance

  • Frequency: Annually or after every 100 hours of riding.
  • Procedure: Disassemble the shock and inspect the air spring components for damage. Lubricate the seals with shock-specific grease to prevent wear and reduce friction.

Damper Service

  • Frequency: Every 100 hours or annually.
  • Procedure: For complete damper maintenance, it’s recommended to send the shock to a professional for servicing. The damper oil can degrade over time, reducing the shock’s responsiveness. Regular servicing ensures the shock is operating at its peak potential.

Seals and Bushings

  • Frequency: Every 6 months or after every 200 hours of riding.
  • Procedure: Check the seals and bushings for wear or damage. If the shock feels unresponsive or begins to leak oil, replacing the seals and bushings may be necessary to restore proper function.

Troubleshooting Common Issues with the Super Deluxe Ultimate RC2T Rear Shock

While the Super Deluxe Ultimate RC2T is designed for reliability, there are a few common issues that riders may encounter. Below are solutions to the most frequent problems:

1. Shock Bottoming Out

  • Cause: Insufficient air pressure or incorrect compression settings.
  • Solution: Increase the air pressure to match your rider weight, or adjust the low-speed compression for a firmer setting.

2. Too Much Rebound

  • Cause: Rebound setting too fast.
  • Solution: Slow down the rebound by adjusting the rebound knob clockwise.

3. Noisy Shock

  • Cause: Dirt or debris in the shock.
  • Solution: Clean the shock thoroughly with a soft cloth. If the noise persists, check for any loose parts or worn bushings.

4. Leaking Oil

  • Cause: Worn seals or excessive pressure.
  • Solution: Replace the seals or bring the shock to a professional for servicing.

Customization and Optimization for Better Performance

The Super Deluxe Ultimate RC2T is a high-performance shock, but riders can further optimize its performance with some thoughtful adjustments.

Adjusting for Rider Preferences

  • Fine-Tune Compression: Adjusting the high-speed and low-speed compression allows you to customize the shock’s response to different types of terrain. If you frequently ride on technical trails, you may want to dial in more low-speed compression to prevent the shock from feeling too soft.
  • Rebound for Handling: Experiment with different rebound settings to find the right balance between comfort and control. If the rebound is too fast, the bike will feel twitchy; too slow, and it may feel sluggish.

Optimizing for Terrain

  • Firm Compression for Smooth Trails: If you’re riding on smoother surfaces, you can adjust the shock to a firmer setting for greater pedaling efficiency.
  • Open Compression for Technical Trails: For rugged trails, leaving the shock in the open setting will allow it to absorb impacts and provide a more comfortable ride.

Comparison with Similar Models

When choosing between the Super Deluxe Ultimate RC2T and other high-end rear shocks, it’s important to consider the specific features that may suit your riding style and needs.

  • Super Deluxe Ultimate RC2T vs. Fox DHX2: Both offer adjustable high-speed and low-speed compression, but the Super Deluxe Ultimate RC2T has a more refined air spring and a two-position compression lever, which can be adjusted on the fly. The DHX2, on the other hand, tends to be more favored by riders looking for coil shock performance, offering more consistent damping.
  • Super Deluxe Ultimate RC2T vs. RockShox Deluxe Select+: The Deluxe Select+ is a more budget-friendly option, offering fewer adjustments than the Super Deluxe Ultimate RC2T. While it’s still an excellent shock, the RC2T provides superior customization, especially for riders who need fine-tuned adjustments for extreme riding conditions.

Compatibility with Other Drivetrain Components

The Super Deluxe Ultimate RC2T rear shock is compatible with a wide range of modern mountain bike frames, but it’s essential to ensure compatibility with other drivetrain components for the best performance.

  • Frame Compatibility: The shock is compatible with frames that support metric sizing, providing a seamless fit with many current bike models. Ensure that your frame’s shock mount dimensions match those of the RC2T.
  • Suspension Travel and Geometry: Adjusting the shock’s travel and rebound settings can help fine-tune the geometry of your bike. Be sure to choose a shock with the correct stroke length and eye-to-eye length for your frame’s specifications.

By carefully considering these factors and adjusting the shock to your riding style, you can maximize the performance of the Super Deluxe Ultimate RC2T rear shock for your specific needs.
