The RockShox Super Deluxe Ultimate RC2T Rear Shock is a high-performance shock designed to improve ride quality, providing exceptional control and comfort on aggressive trails and technical terrain. Whether you’re looking to install, maintain, or optimize your shock, this guide offers a comprehensive overview to ensure your bike is dialed in perfectly for superior performance.
Installation of the Super Deluxe Ultimate RC2T Rear Shock
Installing the Super Deluxe Ultimate RC2T rear shock requires careful attention to detail and the correct tools. Here’s a step-by-step guide to ensure a proper installation:
Tools Required
- 8mm and 10mm hex wrenches
- Torque wrench [paid link]
- Shock pump
- 5mm Allen wrench [paid link]
- Bushing press (if needed)
- Threadlocker (optional)
Installation Steps:
- Prepare the Bike: Ensure your bike is stable on a work stand, and remove any components that might interfere with the shock installation.
- Remove the Old Shock: Using the appropriate hex wrench, loosen the bolts holding the shock in place and carefully remove the old shock. Make sure to note the orientation of the shock mount.
- Install the New Shock: Slide the Super Deluxe Ultimate RC2T into the shock mount and align the eyelet or hardware. Use the correct torque values specified by RockShox to fasten the bolts. Always ensure the bolts are tightened to the proper torque settings to avoid damaging the shock or frame.
- Check for Clearances: Before fully tightening the shock, check that there’s adequate clearance around the shock’s body and mounts. If there are any obstructions, adjust the frame or components to ensure smooth travel.
- Reinstall Any Components: Once the shock is securely in place, reinstall any components that were removed during the installation process, like the rear wheel or brake calipers.
Adjusting the Super Deluxe Ultimate RC2T Rear Shock
The Super Deluxe Ultimate RC2T features dual compression and rebound adjustments, making it crucial to fine-tune settings based on rider preference and riding conditions. Here’s how to make the necessary adjustments:
Compression and Rebound Dials
- Rebound Adjustment: Located on the lower part of the shock, the rebound dial controls how quickly the shock returns after compression. Turn the dial clockwise to slow down the rebound, and counterclockwise to speed it up. Start by setting it to the midpoint and adjust based on feel during riding.
- Low-Speed Compression: The low-speed compression dial allows for fine-tuning the shock’s performance when riding over small bumps and undulating terrain. Set it to a softer setting (counterclockwise) for comfort or stiffer (clockwise) for better control on rougher, high-speed terrain.
- High-Speed Compression: This adjuster is located just above the low-speed compression dial. Use it to tune the shock’s response to large hits and hard landings. A firmer setting will provide better bottom-out resistance, while a softer setting can enhance comfort during descents.
Volume Spacers
The Super Deluxe Ultimate RC2T comes equipped with volume spacers that adjust the shock’s progression through its stroke. Adding more spacers increases the shock’s resistance at the end of the stroke, preventing bottoming out. Fewer spacers offer a more linear feel. Experiment with different setups to find the right balance for your riding style.
Maintaining the Super Deluxe Ultimate RC2T Rear Shock
Regular maintenance is key to preserving the performance of your rear shock and ensuring it lasts. Follow these steps to maintain your Super Deluxe Ultimate RC2T:
Regular Cleaning
- Clean the shock after every ride to remove dirt and debris, especially around the eyelet and damper body. Use a soft cloth or sponge with mild soap and water to avoid damaging the seals.
- Pay particular attention to the shock’s air valve, as dirt and grit can compromise the integrity of the valve over time.
Checking Air Pressure
- The Super Deluxe Ultimate RC2T uses air for compression and rebound damping. Ensure the correct air pressure is maintained for your rider weight and preferred ride feel. Use a shock pump to set the pressure according to the manufacturer’s recommendations.
Oil and Seal Maintenance
- After every 50-100 hours of riding, the shock should be serviced by a professional mechanic or at a service center. The oil should be replaced, and the seals should be checked for wear and tear. RockShox recommends an annual service, especially for aggressive riders.
Troubleshooting Common Issues with the Super Deluxe Ultimate RC2T Rear Shock
Even with the best maintenance practices, issues may arise. Here are some common troubleshooting tips:
Loss of Air Pressure
- If you notice a decrease in air pressure, inspect the air valve and seals for damage. It’s important to replace any damaged seals promptly to prevent air leakage.
- Use a shock pump to re-inflate the shock to the correct pressure. If pressure loss persists, a seal replacement may be necessary.
Excessive Rebound or Compression Speed
- If the rebound or compression settings are too fast or slow, adjust the dials in small increments. Always start with the manufacturer’s recommended baseline settings and fine-tune from there.
- If the shock feels too harsh or too soft despite adjustment, check the oil levels and seals. A servicing might be required to ensure internal components are functioning properly.
Customization and Optimization for Better Performance
The Super Deluxe Ultimate RC2T is designed to be highly tunable, allowing riders to adjust the shock to suit specific riding styles. Customizing the shock can optimize your riding experience by focusing on your needs:
Personalize Suspension Settings
- Weight and Riding Style: If you’re a heavier rider or prefer a firmer shock feel, adjust the low-speed compression and increase air pressure. Lighter riders might prefer a more plush setup with lower air pressure and softer compression settings.
- Terrain Considerations: For technical descents, a stiffer compression setting may help with bottom-out resistance, whereas for smoother, flowy trails, a softer compression setting will provide more comfort and traction.
Shock Tuning with Volume Spacers
- For more aggressive riders or those tackling downhill courses, adding volume spacers increases the progression and helps avoid bottoming out on large impacts.
- Riders seeking a smoother ride with a more linear feel can remove some volume spacers to reduce the ramp-up effect during compression.
Comparison with Similar Models
When choosing a rear shock, it’s essential to compare the Super Deluxe Ultimate RC2T with other models in its category. For instance:
RockShox Super Deluxe Coil
- The Super Deluxe Coil offers a more progressive and plush feel compared to the RC2T’s air-sprung design. While the Super Deluxe Ultimate RC2T provides adjustability, the coil shock offers better performance for riders who prioritize comfort and plushness in rocky or technical conditions.
Fox Float X2
- The Fox Float X2 is another top-tier rear shock, offering similar features to the RC2T. However, the Fox Float X2 is often praised for its more progressive feel and slightly firmer compression adjustments. Riders who prioritize climbing efficiency might prefer the Float X2, while the Super Deluxe Ultimate RC2T shines on longer, more aggressive descents.
Compatibility with Other Drivetrain Components
The Super Deluxe Ultimate RC2T rear shock is compatible with most modern mountain bike frames designed for air shocks. However, compatibility with other drivetrain components, such as suspension forks or rear triangles, should be checked before installation. Ensure that your bike frame is designed to accommodate the shock’s specific dimensions and mounting hardware.
When pairing the RC2T with other suspension components, such as forks or a front shock, ensure that the tuning settings are complementary to avoid inconsistent suspension performance. Ideal compatibility between the front and rear shocks provides smoother transitions between the suspension components during technical rides.
