The RockShox Super Deluxe Ultimate RC2T rear shock is an advanced suspension component designed for high-performance mountain bikes. With a combination of features like dual compression adjustments, adjustable rebound damping, and an air-sprung system, this shock is a favorite for riders seeking to fine-tune their bike for optimal performance. This guide will walk you through installation, adjustment, maintenance, and troubleshooting to help you get the most out of your Super Deluxe Ultimate RC2T.
Installation of the Super Deluxe Ultimate RC2T
The installation process for the Super Deluxe Ultimate RC2T is straightforward but requires precision to ensure maximum performance and safety.
- Prepare the bike: Begin by securing your bike in a stable work stand, making sure the rear wheel is removed for easier access to the shock.
- Remove the old shock: If replacing an existing rear shock, carefully remove the bolts securing it to the frame. You may need a torque wrench [paid link] to avoid over-tightening or under-tightening the bolts.
- Install the new shock: Align the Super Deluxe Ultimate RC2T with the shock mount on your frame. Ensure the eyelet and mounting hardware are properly aligned before tightening the bolts. Always use a torque wrench [paid link] to tighten the bolts to the manufacturer’s specified torque.
- Check clearance and alignment: Make sure the shock sits securely in its mounts and does not interfere with other components on the bike. There should be adequate clearance for the shock’s stroke and any moving parts.
Adjustment of the Super Deluxe Ultimate RC2T
One of the standout features of the Super Deluxe Ultimate RC2T is its adjustability. Tailoring the shock’s performance to your riding style and terrain is key to getting the most from your bike. The shock offers dual compression settings, rebound adjustment, and a ramp-up volume adjuster.
Compression Damping Adjustment
The RC2T has two compression damping circuits: High-Speed Compression (HSC) and Low-Speed Compression (LSC). Both of these are critical for controlling how the shock reacts to different trail conditions.
- High-Speed Compression (HSC): This adjustment controls how the shock reacts to quick, high-impact bumps like drops or rocks. To adjust, turn the HSC dial clockwise to increase resistance or counterclockwise to decrease it. If you’re riding aggressive terrain, consider increasing HSC for more control.
- Low-Speed Compression (LSC): This controls the shock’s response to slower impacts, such as pedaling or slight terrain undulations. Adjust the LSC by turning the dial clockwise to firm up the shock and counterclockwise to soften it. For smoother trails or climbing, reduce LSC to improve comfort.
Rebound Adjustment
Rebound damping controls the speed at which the shock returns to its neutral position after compressing. Set the rebound to your preference by adjusting the rebound knob. To increase rebound damping, turn the knob clockwise; to decrease it, turn it counterclockwise. Start with the recommended factory setting, then adjust based on your riding conditions. For technical descents, slower rebound can prevent “bucking,” while faster rebound is better for more efficient pedaling on smoother surfaces.
Ramp-Up Volume Adjuster
The ramp-up adjuster controls the shock’s progression at the end of its stroke. A higher volume setting (turning the adjuster clockwise) will make the shock ramp up more quickly, preventing bottoming out. A lower volume setting (turning counterclockwise) provides a more linear feel and is ideal for riders seeking a more forgiving ride.
Maintenance of the Super Deluxe Ultimate RC2T
Regular maintenance is crucial to ensure the longevity and performance of your Super Deluxe Ultimate RC2T rear shock. Follow these steps to keep your shock functioning at its best:
- Clean the shock regularly: After each ride, wipe down the shock with a clean cloth to remove dirt, grime, and debris. This will prevent wear on the seals and moving parts.
- Inspect the shock for damage: Check the shock for any signs of leakage, bent components, or cracks. If you notice any issues, it may be time for a rebuild.
- Lubricate the shock: Use appropriate suspension oils to lubricate the shock’s seals. Apply a thin layer to the shaft and other moving parts to reduce friction and wear.
- Check air pressure: Ensure the air pressure in the shock is correct for your weight and riding style. Over time, the air pressure may decrease, so check it before each ride.
Troubleshooting Common Setup Issues
Even with proper adjustment and maintenance, issues can arise with your Super Deluxe Ultimate RC2T. Below are some common problems and how to troubleshoot them:
1. Shock Bottoming Out
If the shock bottoms out frequently, it might be underdamped or under-pressurized. To fix this, adjust the high-speed compression to increase resistance during rapid impacts, or increase the air pressure to prevent excessive travel.
2. Poor Pedaling Efficiency
If you’re experiencing excessive bobbing while pedaling, this may indicate that the low-speed compression is too soft. Increase the LSC to firm up the shock’s response to pedaling forces, particularly when climbing or on smooth trails.
3. Inconsistent Rebound
If the shock returns too quickly or too slowly after compressing, check the rebound setting. Adjust the rebound knob to ensure the shock returns at an appropriate speed for your riding style. If the rebound adjustment does not seem effective, it could be a sign of low oil or air pressure.
4. Shock Leaking
A leaking shock typically indicates a problem with the seals. Inspect the seals for damage or wear, and if necessary, replace them with new ones. Leaks can also be caused by over-tightening the bolts during installation, which can compress the seals too much.
Customization and Optimization for Better Performance
To truly optimize the performance of your Super Deluxe Ultimate RC2T, consider customizing it to suit your riding conditions and style. Below are some strategies for improving the shock’s performance:
- Experiment with Compression Settings: If you find that the bike feels too harsh on high-impact hits, decrease the high-speed compression. Conversely, if the shock feels too soft and you’re losing control, increase the high-speed compression.
- Adjust the Air Pressure: Fine-tuning the air pressure in the shock is critical for achieving the right amount of sag. Adjusting it according to your weight and riding style will improve comfort and control.
- Consider Volume Spacers: If you’re bottoming out too frequently or want more progressiveness, consider adding volume spacers to the air spring. This modification can make the shock more resistant to bottoming out and provide better support for heavier impacts.
Compatibility with Other Drivetrain Components
The Super Deluxe Ultimate RC2T rear shock is designed to work seamlessly with modern mountain bike drivetrains. Its adjustability allows it to complement a wide range of frame geometries and suspension designs. However, compatibility with your specific bike model is essential for achieving the best performance.
- Frame Compatibility: Ensure that the shock’s dimensions and stroke length match your frame’s specifications. Check the shock’s eye-to-eye measurement and stroke length before installation to guarantee proper fitment.
- Suspension Linkage: The shock works well with various suspension linkages, particularly those that emphasize efficient pedaling and plush, controlled descents. Check your frame’s linkage design to ensure it pairs well with the shock’s performance characteristics.
