The RockShox Super Deluxe Ultimate DH [paid link] rear shock is designed to provide exceptional performance for downhill riders. It integrates cutting-edge technology and precision engineering, offering a seamless balance between comfort, control, and durability. In this guide, we will explore the installation, adjustment, maintenance, troubleshooting, optimization, and compatibility of the Super Deluxe Ultimate DH [paid link] rear shock, ensuring riders can get the most out of this premium component.

Installation of the Super Deluxe Ultimate DH Rear Shock

The installation process of the Super Deluxe Ultimate DH rear shock requires precision and attention to detail. Below is a step-by-step guide for installing this shock onto your downhill bike.

Steps for Installation:

  1. Prepare the Bike Frame: Ensure that the bike is properly supported on a work stand, with the rear wheel removed to provide easy access to the shock mounting points.
  2. Remove the Existing Shock: If replacing an old shock, first remove the bolts securing the existing shock to the frame. Use a 5mm Allen wrench [paid link] to unscrew both the upper and lower shock bolts.
  3. Align the Shock with Mounting Points: Align the Super Deluxe Ultimate DH shock with the bike’s rear shock mounting points. The upper mount should be positioned in the frame’s designated shock slot, and the lower mount should rest in the seatstay or rocker link.
  4. Secure the Shock: Install the mounting bolts to secure the shock into position. Ensure that the bolts are torqued to the manufacturer’s recommended specifications (usually around 8-10 Nm for both the upper and lower shock bolts).
  5. Check Shock Travel: Confirm that the shock is correctly positioned and aligned, ensuring full travel without any interference from the frame or other components.

By following these steps, you will ensure a correct and secure installation of the Super Deluxe Ultimate DH rear shock.

Adjustment of the Super Deluxe Ultimate DH Rear Shock

Proper adjustment of the Super Deluxe Ultimate DH rear shock is crucial to achieving optimal performance, comfort, and control. This shock is equipped with multiple adjustable features, such as rebound and compression settings, to fine-tune its behavior for various terrain and riding conditions.

Rebound Adjustment:

Rebound control determines how quickly the shock returns to its original position after compression. To adjust the rebound:

  1. Turn the rebound knob clockwise to slow the rebound (i.e., slower return).
  2. Turn the rebound knob counterclockwise to speed up the rebound (i.e., faster return).
  3. Adjust the rebound to your preference by testing the bike’s suspension response on different trail features.

Compression Adjustment:

The Super Deluxe Ultimate DH shock offers high and low-speed compression adjustments to fine-tune the shock’s responsiveness to both small and large bumps.

  • High-Speed Compression: This adjustment controls how the shock reacts to big hits and aggressive impacts.
    • To increase high-speed compression, turn the knob clockwise.
    • To decrease high-speed compression, turn the knob counterclockwise.
  • Low-Speed Compression: This affects the shock’s response to more subtle, low-speed movements (e.g., pedaling force).
    • Increase low-speed compression by turning the knob clockwise.
    • Decrease low-speed compression by turning the knob counterclockwise.

Air Pressure Adjustment:

The Super Deluxe Ultimate DH uses a negative and positive air spring system. Adjusting the air pressure is essential for achieving the correct balance between comfort and control.

  1. Use a shock pump to adjust the positive air spring pressure based on rider weight and riding style.
  2. A good starting point is to set the sag to around 30% of the shock’s total travel, though this can vary based on the rider’s preferences and the terrain.

Maintenance of the Super Deluxe Ultimate DH Rear Shock

Regular maintenance is essential to keep your Super Deluxe Ultimate DH rear shock performing at its best. The shock is built to endure the demands of downhill riding, but it still requires periodic attention to maintain optimal performance.

Cleaning:

  1. After every ride, clean the shock with a damp cloth to remove dirt and debris. Be sure to avoid using harsh chemicals or solvents that could damage the shock.
  2. Check the shock for any signs of oil leakage or damage, especially around the seals.

Servicing:

  • Annual Service: It is recommended to service the Super Deluxe Ultimate DH rear shock at least once a year. This includes a full rebuild with new seals, oil, and necessary parts. If the shock is used in more extreme conditions, more frequent servicing may be required.
  • Seal Cleaning: During each service, clean the seals to ensure that they continue to protect the internal components from contaminants. Replacing seals every 6-12 months is a good practice for preventing leaks and maintaining smooth shock action.

Lubrication:

Ensure that the shock’s moving parts are adequately lubricated, as this will help minimize wear and maintain performance. Apply a light coat of lubricant to the shock shaft and other moving components as recommended by the manufacturer.

Troubleshooting Common Set-Up Issues

Even with the best components, riders may encounter setup issues with the Super Deluxe Ultimate DH rear shock. Here are some common problems and how to resolve them:

Shock Bottoming Out:

  • Problem: The shock bottoms out on large hits or rough terrain.
  • Solution: Increase the air pressure slightly to improve the shock’s resistance to compression. Alternatively, adjust the compression settings to better handle high-speed impacts.

Rebound Issues:

  • Problem: The shock rebounds too quickly or too slowly.
  • Solution: Adjust the rebound knob according to the trail conditions. If the shock rebounds too quickly, increase the rebound damping by turning the knob clockwise. If it’s too slow, turn the knob counterclockwise to reduce rebound damping.

Air Leaks:

  • Problem: The shock loses air pressure.
  • Solution: Check the shock’s air valves and seals for damage. If there is any sign of leakage, replace the seals or consult a technician for an in-depth service.

Customization and Optimization for Better Performance

Customizing the Super Deluxe Ultimate DH rear shock can significantly improve performance on your bike, allowing you to optimize your ride for specific terrain and riding styles.

Fine-Tuning for Terrain:

  • For rocky terrain, a higher compression setting with slightly increased air pressure will provide better control over impacts.
  • On fast, smooth tracks, lower compression and reduced air pressure can allow for more plush, responsive suspension behavior.

Rider Weight and Riding Style:

Adjusting the air pressure to match the rider’s weight is essential. Heavier riders will generally require higher air pressures, while lighter riders may benefit from lower pressures. Additionally, adjusting the rebound and compression based on riding style—whether aggressive or smooth—will optimize the shock’s performance.

Comparison with Similar Models

When comparing the Super Deluxe Ultimate DH rear shock to similar models, such as the Fox DHX2 or the Cane Creek Double Barrel, it stands out in several areas.

  • Shock Adjustability: The Super Deluxe Ultimate DH offers a wider range of compression and rebound adjustments, providing more precise tuning options for riders.
  • Weight: The RockShox model is typically lighter than some competitors, offering better weight distribution without sacrificing durability.
  • Performance: Riders who prioritize control and handling on rough, downhill trails may find the Super Deluxe Ultimate DH’s performance superior due to its refined damping system.

Compatibility with Other Drivetrain Components

The Super Deluxe Ultimate DH rear shock is designed to work seamlessly with other high-performance downhill components. However, it is essential to ensure that the shock’s mounting specifications align with your bike frame. Check the shock’s eye-to-eye length and stroke length to confirm compatibility with your bike’s rear triangle.

Additionally, the shock’s air spring system may interact with specific fork models. Pairing this shock with a matching RockShox fork will maximize performance, but it can also function with other brands as long as the suspension design is balanced. Riders should also consider their wheel size and frame geometry when integrating the shock into their setup.
