The RockShox Super Deluxe Ultimate RC2T rear shock is one of the most highly regarded suspension components in the mountain biking world. Known for its advanced features, excellent performance, and versatility, this rear shock is a top choice for riders seeking an edge on rough terrain. This article will explore the installation, adjustment, maintenance, troubleshooting, customization, and compatibility of the Super Deluxe Ultimate RC2T. Additionally, we will compare it to similar models to help riders make an informed decision.
Installation of the Super Deluxe Ultimate RC2T
Installing the Super Deluxe Ultimate RC2T is a relatively straightforward process, but it requires attention to detail to ensure optimal performance. Here’s a step-by-step guide to properly install the rear shock:
- Remove the Old Shock: Begin by removing your existing rear shock. Use appropriate tools to unscrew the shock bolts, keeping the hardware safe for reuse.
- Prepare the New Shock: Before installation, verify that the Super Deluxe Ultimate RC2T is compatible with your bike’s frame and suspension design. Ensure that the shock’s eyelet sizes match those on your bike.
- Position the Shock: Align the shock with the frame mounts. The Super Deluxe Ultimate RC2T uses a traditional eyelet mounting system, so the shock should fit directly into the mounts without any force.
- Install the Bolts: Insert the bolts through the shock’s eyelets and the frame’s mounting points. Tighten the bolts according to the manufacturer’s torque specifications. Over-tightening may lead to damage, while under-tightening can cause instability.
- Check the Setup: Once the shock is installed, check for any free play or misalignment. Make sure the shock moves smoothly through its travel range.
- Test the Installation: After installation, perform a visual inspection to ensure everything is secure. Test the suspension by compressing it and checking for smooth operation.
Adjustment of the Super Deluxe Ultimate RC2T
One of the key features of the RockShox Super Deluxe Ultimate RC2T is its adjustability. The shock provides multiple adjustments to fine-tune the ride to the rider’s preferences. These include:
Compression Damping Adjustments
The Super Deluxe Ultimate RC2T offers external compression adjustments that allow you to modify how the shock responds to small bumps and large hits. The high-speed and low-speed compression adjustments give you control over the suspension’s responsiveness in different trail conditions.
- Low-Speed Compression: Adjust this to control how the shock handles smaller impacts and general trail chatter. Tightening the low-speed compression results in a firmer ride, while loosening it provides a more plush feel.
- High-Speed Compression: This controls how the shock responds to larger impacts, such as drops or big hits. For aggressive riders or those tackling technical descents, setting this to a firmer setting can prevent bottoming out.
Rebound Damping
Rebound damping controls how quickly the shock returns to its original position after compression. For rough, rocky trails, slower rebound settings are recommended to prevent the rear wheel from bouncing off the ground too quickly. For smoother trails, faster rebound settings can offer a livelier feel.
Spring Rate and Volume Spacers
Adjusting the spring rate or volume spacers allows the rider to modify the shock’s travel characteristics. Riders can add or remove spacers to control bottom-out resistance and the overall feel of the shock throughout its stroke.
Maintenance of the Super Deluxe Ultimate RC2T
Maintaining your Super Deluxe Ultimate RC2T rear shock is essential for ensuring optimal performance and longevity. Regular maintenance helps prevent wear and tear, keeping your bike’s suspension in top shape. Follow these key maintenance tasks:
- Clean the Shock Regularly: Dirt and debris can accumulate around the shock, especially after muddy or wet rides. Wipe down the shock with a clean rag after each ride, paying special attention to the seals.
- Check for Leaks: Periodically inspect the shock for any signs of oil leakage. If there is any visible oil on the shock body, it may indicate a need for a seal replacement.
- Service Interval: RockShox recommends servicing the Super Deluxe Ultimate RC2T shock at least once a year or every 50 hours of ride time, whichever comes first. This involves disassembling the shock, cleaning internal components, and replacing seals or bushings as needed.
- Air Pressure Maintenance: The air chamber should be checked and adjusted according to the rider’s weight and preferred sag settings. Over time, air pressure can decrease, affecting the shock’s performance. Regularly check and adjust the pressure before each ride.
Troubleshooting Common Set-Up Issues
Despite its exceptional design, the Super Deluxe Ultimate RC2T may encounter issues during installation or use. Here are some common troubleshooting tips:
Shock Bottoming Out
- Cause: The shock may bottom out if the spring rate is too soft or if the volume spacers are not set correctly.
- Solution: Increase air pressure or add volume spacers to prevent bottoming out during big hits.
Excessive Rebound
- Cause: If the shock feels too bouncy, the rebound damping may be too fast.
- Solution: Slow down the rebound setting to allow the shock to return more slowly, providing better traction.
Suspension Feels Too Firm
- Cause: The low-speed compression may be set too high, or the spring rate might be too stiff.
- Solution: Reduce the low-speed compression setting or adjust the spring rate to make the suspension more plush.
Customization and Optimization for Better Performance
The Super Deluxe Ultimate RC2T is designed with performance optimization in mind. Riders can further customize their suspension by:
- Fine-tuning Compression Settings: Adjusting the compression settings based on the type of terrain you ride most often can greatly improve ride quality. Softer settings are ideal for cross-country rides, while stiffer settings are necessary for aggressive enduro or downhill trails.
- Changing Volume Spacers: By adding or removing spacers, riders can adjust the shock’s progression. More spacers can provide a firmer feel and reduce bottoming out, while fewer spacers can provide a more linear stroke.
- Spring Rate Selection: The Super Deluxe Ultimate RC2T comes with various spring rates. Choosing the right spring rate for your weight and riding style ensures that the shock performs optimally without sacrificing comfort or control.
Comparison with Similar Models
While the Super Deluxe Ultimate RC2T excels in many areas, it’s worth comparing it with similar models on the market to determine if it’s the best rear shock for your needs.
Fox Float X2
- Performance: The Fox Float X2 is another high-performance rear shock designed for aggressive riders. While both shocks offer similar compression and rebound adjustments, the Float X2 tends to be more progressive, making it ideal for riders who require more mid-stroke support.
- Customization: Both shocks offer ample customization, but the RockShox Super Deluxe Ultimate RC2T provides a smoother feel in the small-bump zone, making it better suited for riders who prefer a plush ride.
DVO Jade X
- Performance: The DVO Jade X rear shock provides excellent adjustability, similar to the Super Deluxe Ultimate RC2T. However, it is often seen as slightly stiffer, which could be preferable for heavier riders or those who ride technical downhill trails.
- Customization: The Jade X offers a variety of tuning options, but it lacks the easy-to-use adjustments found in the RockShox model.
Understanding Compatibility with Other Drivetrain Components
When considering the Super Deluxe Ultimate RC2T, it’s important to ensure compatibility with other components, such as the bike’s drivetrain. The rear shock must work in harmony with the frame’s geometry and suspension design, ensuring smooth suspension travel and reliable performance. The Super Deluxe Ultimate RC2T is compatible with most modern mountain bike frames, including those from brands like Trek, Yeti, and Specialized, making it a versatile choice for a wide range of bikes.
