This shock model is built to withstand the extreme conditions of downhill riding, offering riders enhanced performance on rough and technical terrain. In this guide, we will cover the installation, adjustment, maintenance, troubleshooting, and customization of the Super Deluxe Ultimate DH [paid link] rear shock, along with how it compares to similar models.
Installation of the Super Deluxe Ultimate DH Rear Shock
Installing the Super Deluxe Ultimate DH rear shock requires careful attention to ensure proper setup and performance. The shock is designed to be compatible with most modern downhill bikes, but always check for specific frame compatibility before installation.
Step-by-Step Installation
- Remove the Old Shock (if applicable)
- If replacing an old shock, begin by removing the existing shock. Use the appropriate tools to remove the mounting bolts at both ends of the shock. Ensure the bike is stable and supported before detaching the shock.
- Prepare the New Super Deluxe Ultimate DH Shock
- Unbox the shock and inspect it for any damage. Confirm that it matches the specifications required for your bike, such as eye-to-eye length and stroke length.
- Install the Upper Mount
- Position the shock in the frame’s upper mount, ensuring the shock’s eyelet is properly aligned. Insert the bolt and torque it to the manufacturer’s recommended specification.
- Install the Lower Mount
- Align the lower eyelet with the frame’s lower mount. Insert the bolt and tighten it. Make sure both mounting bolts are securely fastened.
- Check for Proper Movement
- Compress the shock a few times by hand to ensure it moves freely and doesn’t encounter any resistance or binding.
- Check the Setup
- Once installed, check the shock for proper alignment, and verify that all bolts are properly torqued.
Tools Required for Installation
- Torque wrench [paid link]
- 8mm or 10mm allen wrench [paid link]
- Shock pump
- Grease (optional)
- Rags for cleaning
Adjusting the Super Deluxe Ultimate DH Rear Shock
Adjusting the Super Deluxe Ultimate DH rear shock is key to optimizing its performance for specific riding conditions. This shock offers a range of adjustments that allow riders to fine-tune the suspension to their weight, riding style, and terrain.
Key Adjustments to Consider
- Sag Setting
The sag refers to how much the shock compresses under the rider’s weight. Set the sag between 25-30% of the shock’s total travel for optimal performance. Use a shock pump to adjust the air pressure and check the sag by sitting on the bike and measuring the shock’s compression. - Rebound Adjustment
The rebound adjuster controls how quickly the shock returns after compression. For downhill riding, a slower rebound is typically preferred to keep the bike stable and prevent it from bouncing excessively after hitting obstacles. - Compression Adjustment
The compression setting controls how much the shock resists compression when hitting obstacles. For aggressive downhill riding, you’ll want a stiffer compression setting, which helps to prevent bottoming out on big impacts. - High-Speed and Low-Speed Compression
The Super Deluxe Ultimate DH allows for fine-tuning both high-speed and low-speed compression. High-speed compression affects the shock’s performance when hitting fast, harsh impacts, while low-speed compression affects smaller, more controlled impacts. - Volume Spacers
The shock includes adjustable volume spacers to modify the air spring curve. More spacers result in a more progressive feel, ideal for riders who want to avoid bottoming out during aggressive riding.
Maintaining the Super Deluxe Ultimate DH Rear Shock
Proper maintenance is essential for keeping the Super Deluxe Ultimate DH rear shock functioning at its best. Regular servicing ensures the shock continues to perform at a high level and prevents wear over time.
Cleaning and Inspection
- Clean the Shock Regularly
After each ride, wipe down the shock with a soft cloth to remove dirt and debris. Check for any damage or wear on the shock body, seals, and mounting hardware. - Inspect the Shock Seals
Inspect the seals periodically for any signs of wear or leakage. If the seals are damaged, they should be replaced to maintain proper function and prevent oil leaks.
Oil and Air Pressure Maintenance
- Change the Oil
The Super Deluxe Ultimate DH shock uses high-quality oil to ensure smooth performance. Every 50 hours of use or once a year, the oil should be changed to maintain optimal performance. - Check the Air Pressure
The air pressure in the shock should be checked regularly, especially before rides. Use a shock pump to adjust the pressure based on the rider’s weight and riding style.
Spring Maintenance
If the shock uses a coil spring, make sure to check the spring’s condition. Over time, coil springs can lose their tension, which will affect the shock’s performance. Replacing the spring when it shows signs of wear is necessary for maintaining the shock’s responsiveness.
Troubleshooting Common Issues
While the Super Deluxe Ultimate DH rear shock is a high-performance component, occasional issues may arise. Here are some common problems and their solutions:
Loss of Air Pressure
- Cause: Air pressure can leak over time, especially if the seals or the shock body is damaged.
- Solution: Check for leaks by visually inspecting the seals. If air is leaking, replace the seals or take the shock for servicing.
Poor Rebound Control
- Cause: If the shock is not returning to its original position smoothly, it may be due to incorrect rebound settings or oil degradation.
- Solution: Adjust the rebound settings to the preferred level. If the issue persists, service the shock and replace the oil.
Bottoming Out Too Easily
- Cause: Bottoming out occurs when the shock compresses too much during a hard hit. This can happen if the compression settings are too soft or if the air pressure is too low.
- Solution: Increase the compression settings and check the air pressure. Adding volume spacers can also help prevent bottoming out.
Customizing the Super Deluxe Ultimate DH Rear Shock
The Super Deluxe Ultimate DH rear shock offers a high level of customization to ensure it meets the specific needs of the rider. Riders can adjust the air spring, compression settings, and volume spacers to tailor the shock’s behavior on different types of terrain. Additionally, adding a custom coil spring may be beneficial for riders who prefer the predictable performance of a coil shock.
Comparison with Similar Models
The Super Deluxe Ultimate DH rear shock is often compared with other downhill-specific shocks, such as the Fox DHX2 and the Öhlins TTX22M. While all these shocks offer excellent performance, the Super Deluxe Ultimate DH stands out with its ability to fine-tune both high-speed and low-speed compression, along with its user-friendly air spring adjustments.
The Fox DHX2, for instance, uses a coil spring which can be more durable but requires more maintenance and offers less adjustability in terms of air spring progression. The Öhlins TTX22M is known for its smooth performance but lacks the volume spacers and air spring adjustments available on the RockShox model.
Overall, the Super Deluxe Ultimate DH is ideal for riders seeking the perfect balance of performance, adjustability, and durability for aggressive downhill riding.
Compatibility with Other Drivetrain Components
The Super Deluxe Ultimate DH rear shock is designed to work seamlessly with most modern downhill bike frames and drivetrain systems. However, it is crucial to ensure compatibility between the shock’s eye-to-eye length and stroke length and the frame’s suspension design. Always consult your bike’s specifications to ensure the shock will work with the frame without issues. Additionally, the shock’s performance can be further optimized by pairing it with other high-performance components from RockShox, such as the RockShox Boxxer fork.
In conclusion, the Super Deluxe Ultimate DH rear shock is a top-tier option for downhill riders, offering exceptional adjustability, performance, and durability. By following the installation, adjustment, and maintenance guidelines, riders can ensure their shock provides optimal performance on every ride.
