The RockShox Deluxe Ultimate RCT rear shock is designed to provide riders with excellent control and performance on demanding trails. Whether you’re an experienced rider or a beginner, understanding how to properly install, adjust, maintain, and troubleshoot your Deluxe Ultimate RCT will ensure that you get the most out of your suspension system. This guide offers a detailed approach to these aspects, helping you enhance the performance and lifespan of your rear shock.
Installation of the Deluxe Ultimate RCT Rear Shock
Installing the RockShox Deluxe Ultimate RCT rear shock requires precision and attention to detail to ensure optimal performance. Follow these steps for a correct installation:
- Remove the Old Shock
Begin by safely removing the old shock from your bike frame. Depending on your bike, this could involve loosening bolts on both the shock mount and the frame. Keep track of the washers and bushings for reuse or replacement. - Prepare the New Shock
Before installing the Deluxe Ultimate RCT, inspect it for any shipping damage. Check that the air valve and compression settings are properly set to factory specifications. - Mount the Shock
Carefully align the mounting points of the shock with the bike’s rear triangle. Secure the top and bottom mounts using the provided hardware. Tighten the bolts to the specified torque settings as mentioned in the shock’s manual to avoid over-tightening, which could damage the frame or shock. - Set the Sag
After installation, set the sag according to your weight and riding style. This ensures that the shock functions optimally, absorbing bumps and impacts as intended. - Final Check
Ensure that all bolts are securely tightened and the shock is seated correctly within the mounts. Test the rear suspension by compressing the shock and checking for smooth movement without any interference.
Adjusting the Deluxe Ultimate RCT Rear Shock
The RockShox Deluxe Ultimate RCT rear shock offers several adjustable settings that cater to different riding conditions. Proper adjustment is essential for maximizing comfort and performance.
1. Rebound Adjustment
The rebound knob on the Deluxe Ultimate RCT allows you to control the speed at which the shock returns to its original position after compression. A faster rebound is useful for smoother terrain, while a slower rebound provides more control on rougher trails. Begin by setting the rebound to a mid-range setting and adjust from there based on your ride preferences.
2. Compression Adjustment
The compression adjuster allows you to control how the shock compresses under load. There are typically low and high-speed compression settings. Adjust the low-speed compression for rough terrain to prevent bottoming out, while the high-speed compression helps with handling big hits and maintaining stability at high speeds.
3. Air Pressure
Adjusting the air pressure in the Deluxe Ultimate RCT is crucial for achieving the proper sag. Use a shock pump to adjust the pressure based on your weight and riding style. Always check that the shock pump is compatible with the air valve on your shock, ensuring an accurate pressure reading.
Maintenance of the Deluxe Ultimate RCT Rear Shock
To keep the Deluxe Ultimate RCT rear shock performing at its best, regular maintenance is required. Here’s a maintenance routine to follow:
1. Clean the Shock
After every ride, especially in muddy or wet conditions, clean the shock with a damp cloth to remove dirt and debris. Avoid using high-pressure water, as it can force contaminants into the shock’s seals.
2. Inspect for Leaks
Periodically check the shock for any signs of oil leakage. Leaks may indicate a problem with the seals, which should be addressed promptly to prevent damage.
3. Lubricate the Seals
Apply a small amount of suspension oil to the shock’s seals regularly. This prevents them from drying out and helps maintain smooth movement.
4. Full Service
A full service should be performed every 50-100 hours of riding, or at least once a year. This involves removing the shock from the frame, disassembling it, and inspecting all internal components. If any parts show signs of wear, such as the seals or internal bushings, replace them to avoid performance degradation.
Troubleshooting Common Issues with the Deluxe Ultimate RCT Rear Shock
Despite its durability, the Deluxe Ultimate RCT rear shock can experience issues from time to time. Here’s how to address some common problems:
1. Shock Bottoming Out
If the shock bottoms out too easily, check the air pressure to ensure it’s set correctly for your weight. If the pressure is fine, try adjusting the compression settings to increase resistance.
2. Lack of Rebound Control
If you notice that the shock rebounds too quickly or too slowly, adjust the rebound knob. If the problem persists, the shock may need a full service to inspect internal components.
3. Noise During Compression
A knocking or creaking noise may occur if the shock’s mounting hardware is loose or if there’s debris in the shock’s bushings. Check and clean the mounts, then ensure everything is tightly secured.
4. Oil Leaks
If you notice oil leaking from the shock, the seals may need to be replaced. If the shock is under warranty, consult RockShox for potential replacement or repair services.
Customization and Optimization for Better Performance
To optimize the performance of the Deluxe Ultimate RCT rear shock, consider making adjustments based on your riding style and terrain:
1. Tuning for Trail Riding
For trail riding, you may want a more plush feel, which can be achieved by reducing air pressure and using a softer compression setting. This allows the shock to absorb smaller impacts, offering a smoother ride over uneven surfaces.
2. Racing Setup
If you’re racing, optimizing for responsiveness and control is key. Increase the air pressure for better pedaling efficiency and adjust the compression settings to handle the fast, aggressive hits often encountered in competitive settings.
3. Enduro or Downhill Setup
For aggressive downhill or enduro riding, set the shock to provide more support. Increase both air pressure and compression settings to ensure the shock doesn’t bottom out when absorbing large impacts.
Comparison with Similar Models
When choosing a rear shock, it’s essential to compare the Deluxe Ultimate RCT with similar models in the market. Here’s how it stacks up against other high-performance shocks:
1. Deluxe RCT vs. Deluxe Ultimate RCT
The Deluxe Ultimate RCT is the upgraded version of the Deluxe RCT, with additional adjustments and a more refined damper for better control. The Ultimate version includes more advanced features, such as a high-speed compression dial and a more precise rebound adjustment, making it ideal for riders who demand more from their suspension.
2. Deluxe Ultimate RCT vs. Fox DPX2
The Fox DPX2 is another popular rear shock that competes with the Deluxe Ultimate RCT. While both offer excellent performance, the Fox DPX2 tends to be a bit stiffer, making it more suitable for aggressive riders, whereas the Deluxe Ultimate RCT provides more tunability for smoother rides. The choice between the two comes down to personal preference and riding style.
Understanding Compatibility with Other Drivetrain Components
The Deluxe Ultimate RCT rear shock is designed to work seamlessly with a wide variety of bike frames and drivetrain systems. However, compatibility is an essential consideration for maintaining optimal performance:
- Frame Compatibility: The shock features a trunnion mount, which is common in modern bike frames. Ensure that your bike frame supports this type of mounting before purchase.
- Drivetrain and Suspension Linkage: If you’re upgrading or building a bike from scratch, ensure that the rear shock’s travel and mounting specifications align with your bike’s suspension linkage. This ensures that the shock works efficiently within your bike’s overall suspension system.
- Coil vs. Air Shocks: If you are switching from a coil shock, the Deluxe Ultimate RCT (being an air shock) may offer different handling characteristics. Adjusting your suspension setup to account for these differences will help ensure a smooth transition.
