Whether you’re an experienced rider looking for high performance or a beginner wanting an upgrade, the Super Deluxe Ultimate RC2T offers exceptional control, comfort, and durability. In this guide, we will dive into its installation, adjustment, maintenance, troubleshooting, customization, and performance optimization to help you get the most out of this high-end rear shock.
Installation of the Super Deluxe Ultimate RC2T Rear Shock
Installing the RockShox Super Deluxe Ultimate RC2T rear shock requires precise steps to ensure optimal performance. The shock is designed for easy installation, but following the right steps is crucial to avoid any issues.
- Preparation
Before installing, ensure your bike frame and the shock are clean and free from dirt and debris. Check the shock’s eyelet and mounting hardware for any signs of wear. - Mounting the Shock
The Super Deluxe Ultimate RC2T uses a traditional mounting system with an upper and lower eyelet.- Position the upper eyelet into the frame mount and secure it with the appropriate bolt. Tighten the bolt to the specified torque setting (usually 8-10 Nm).
- Do the same for the lower eyelet. Check that the shock is aligned properly within the frame and the linkage.
- Setting the Sag
Set the sag according to your weight and riding style. Typically, this is between 25-30% of the shock’s total travel. Adjust the air pressure via the valve on the top of the shock. - Final Checks
Once the shock is securely installed, check the function by compressing the shock manually to ensure smooth movement. Double-check the tightness of all bolts.
Adjustment and Customization of the Super Deluxe Ultimate RC2T
The Super Deluxe Ultimate RC2T rear shock is highly customizable, allowing riders to fine-tune the shock to match their specific needs.
Rebound and Compression Damping Adjustments
- Rebound Damping
The rebound damping controls how quickly the shock returns to its original position after compression. Adjusting it to your preference can make a significant difference in ride quality. Turn the rebound knob located at the bottom of the shock to increase or decrease rebound speed. If you want the shock to return more slowly, tighten the knob. If it’s too slow, loosen it for a faster return. - Compression Damping
The RC2T shock allows for high- and low-speed compression damping adjustments, which are crucial for controlling how the shock responds to different types of terrain.- The high-speed compression knob controls the shock’s resistance to fast impacts, such as hitting drops or landing jumps.
- The low-speed compression knob adjusts the resistance to slow, steady impacts, such as when you ride over rough terrain or loose trails.
Air Pressure
The air pressure in the Super Deluxe Ultimate RC2T is key to achieving the right balance between support and comfort. Refer to RockShox’s recommended air pressure settings based on rider weight. You can fine-tune the pressure based on your preferences for climbing or descending.
Hydraulic Lockout
The RC2T features a hydraulic lockout option, which is useful for reducing bobbing during climbs. Adjust the lockout feature by turning the dial at the top of the shock. Be sure to unlock it when descending or when you need full shock movement for rough terrain.
Maintenance of the Super Deluxe Ultimate RC2T
Maintaining the Super Deluxe Ultimate RC2T rear shock ensures its longevity and smooth performance. Regular servicing will keep it in top shape, reducing the risk of issues on the trail.
Cleaning the Shock
After every ride, it’s important to clean the shock and remove any dirt or debris. Use a soft cloth and warm soapy water to wipe down the shock body. Avoid using harsh chemicals that could damage the seals or paint.
Air Spring Maintenance
- Regularly check the air pressure, especially if you notice a change in performance. Air springs may lose pressure over time due to small leaks or temperature fluctuations.
- You can add air using a shock pump designed for the Super Deluxe Ultimate RC2T. Always check the pressure before each ride.
Damper Service
To ensure that the damping system remains functional, it’s essential to service the shock regularly. RockShox recommends a full damper service every 50-100 hours of riding or annually, depending on the intensity of your rides. This involves draining the damper fluid, cleaning the internal components, and replacing any worn seals or O-rings.
Seal Maintenance
Over time, the seals on the shock may wear out or dry out, affecting performance. Inspect the seals every few months, and if necessary, apply suspension grease to keep them lubricated. For the best results, replace seals when they start to show signs of wear.
Troubleshooting Common Setup Issues
While the Super Deluxe Ultimate RC2T is a high-quality rear shock, there are some common setup issues you might encounter. Here are a few things to check:
Unresponsive Rebound or Compression
If you notice that the rebound or compression isn’t responding to adjustments:
- Ensure the knobs are not stuck and that you can feel resistance when turning.
- Check for any dirt or debris blocking the damping system. A thorough cleaning can often resolve this issue.
- If the problem persists, the damper may need a full service.
Sag Issues
If the sag is not setting correctly, it could be due to incorrect air pressure or improper rider weight settings. Recheck your weight and adjust the air pressure accordingly. Also, ensure the shock is not over- or under-inflated.
Noisy Shock
If you hear knocking or strange noises coming from the shock, inspect the mounting hardware to ensure everything is tight and secure. Noise can also come from worn-out seals or a lack of lubrication, so check the seals for any signs of wear.
Optimizing Performance of the Super Deluxe Ultimate RC2T
The Super Deluxe Ultimate RC2T can be optimized for performance based on your riding style and terrain.
Adjusting for Downhill Riding
For aggressive downhill riding, you’ll want to ensure that the shock has enough support to handle high-speed hits and large drops.
- Set the rebound to a medium-to-fast setting to ensure quick recovery after each compression.
- Increase the low-speed compression to prevent excessive shock movement during high impacts.
Adjusting for Cross-Country Riding
For cross-country riding, where efficiency and pedaling performance are key, adjust the shock to minimize bobbing.
- Set the hydraulic lockout feature to reduce movement during climbs.
- Tune the compression to be firmer to provide optimal support when riding on smoother terrain.
Comparison with Similar Models
When comparing the RockShox Super Deluxe Ultimate RC2T to other rear shocks, it becomes clear that this model excels in high customization and tuning options. Here’s how it stacks up:
- Fox Float X2: While both shocks offer excellent performance, the Super Deluxe Ultimate RC2T offers more fine-tuned damping control with its dual-speed compression and rebound settings, making it ideal for riders who want to dial in their shock precisely for different trail conditions.
- Ohlins TTX Air: The Ohlins shock is also a high-performance model, but it is generally more expensive. The Super Deluxe Ultimate RC2T offers a more affordable alternative with similar performance features, including high and low-speed compression adjustments.
Understanding Compatibility
The Super Deluxe Ultimate RC2T is designed to work seamlessly with most modern mountain bike frames. However, it’s essential to check the compatibility with your bike’s geometry and other drivetrain components.
- Axle Type: Make sure the shock matches your frame’s axle standards (e.g., 12mm or 15mm).
- Mounting Standards: The eyelet dimensions should align with your bike’s shock mount.
- Travel Length: Verify that the shock’s travel length fits your frame’s suspension design.
