Preparing for Service

Before beginning any service on your Super Deluxe Ultimate DH rear shock, it’s essential to ensure that you have a clean, well-lit workspace. A clutter-free area will allow you to focus on the task at hand, minimizing the risk of mistakes or loss of small parts.

Step 1: Remove the Shock from the Frame

  • To begin, place your bike on a stand to stabilize it.
  • Use the 8mm Allen wrench to remove the rear shock from the frame. Depending on your bike, you may also need to use a 10mm socket wrench to remove any additional bolts securing the shock.
  • Once the shock is free, ensure that you place it on a clean surface to prevent contamination from dirt or debris.

Step 2: Prepare the Shock for Disassembly

  • Make sure that the shock is not under pressure. Use the shock pump to release any remaining air pressure in the shock.
  • Position the shock so that the damper side is facing upward. This ensures that the oil does not spill when the shock is disassembled.

Disassembling the Super Deluxe Ultimate DH Shock

Step 3: Remove the Eyelets and Lower Mount

  • Start by loosening the screws that secure the eyelet and lower mount using a 10mm wrench.
  • Carefully remove the eyelet and the lower mount. Be cautious during this process as the parts can sometimes become stuck due to dirt or debris.
  • Inspect the eyelet and mount for wear or damage. Replace these parts if needed.

Step 4: Remove the Air Can

  • With the eyelet and lower mount removed, you can now focus on the air canister. Use a 2.5mm Allen wrench to remove the air can screws.
  • Once the screws are removed, gently slide the air can off the main body of the shock. If resistance is met, tap it lightly with a rubber mallet to loosen it.
  • Carefully inspect the internal components for wear or dirt buildup. Clean all parts thoroughly before moving to the next step.

Servicing the Internal Components

Step 5: Clean the Components

  • Use a clean rag to wipe down the air can, damper shaft, and other internal parts. Remove any dirt or grime that may have built up over time.
  • Take extra care to clean the seals and bearing surfaces. Contaminants here can cause friction, leading to poor performance or damage.
  • Inspect the damper shaft for any signs of scoring or excessive wear. Replace any components that show damage.

Step 6: Replace the Seals

  • If the shock has been ridden extensively or if you’ve noticed any leakage, it’s a good idea to replace the seals.
  • Using the RockShox seal kit, replace the main seals, wiper seals, and the oil seal head. These parts ensure that the shock operates smoothly and prevents air or oil leaks.
  • Apply a small amount of grease to the seal surfaces to ensure a proper fit and reduce friction when reassembling the shock.

Step 7: Reassemble the Shock

  • Once the seals are replaced and all components have been thoroughly cleaned, it’s time to reassemble the shock.
  • Carefully slide the air can back onto the damper body, ensuring that the seals align properly.
  • Tighten the air can screws to the recommended torque specifications, typically 8-10 Nm. Ensure the screws are evenly torqued to avoid creating uneven pressure on the shock.

Reinstalling the Shock

Step 8: Attach the Shock to the Frame

  • Place the shock back onto your bike frame, securing it with the appropriate bolts.
  • Use the 8mm Allen wrench to tighten the bolts. Be sure not to overtighten, as this can damage the frame or the shock.
  • Double-check that the shock is seated correctly and securely fastened to the frame.

Step 9: Set the Air Pressure

  • Using a shock pump, set the air pressure according to your weight, riding style, and the specifications of your shock. The Super Deluxe Ultimate DH is highly adjustable, so you can fine-tune it to your exact preferences.
  • It’s essential to check the air pressure periodically during the riding season, especially if you notice any changes in performance.

Troubleshooting Common Set-Up Issues

While the Super Deluxe Ultimate DH rear shock is designed to be robust and reliable, users may encounter some common issues. Here are a few troubleshooting tips:

Issue 1: No Rebound or Insufficient Rebound

  • If the rebound damping is not working properly, it could be due to a low oil level or air contamination. Make sure to replace any seals that may be allowing air to enter the system.
  • Check that the rebound knob is functioning properly, and that it is correctly calibrated according to the user manual.

Issue 2: No Compression or Insufficient Compression

  • If the compression is not working, inspect the internal compression damper for contamination or damage.
  • Low oil levels or faulty seals can also cause insufficient compression. Replacing seals and ensuring that all internal components are clean and functioning correctly should resolve the issue.

Issue 3: Leaking Oil

  • Oil leaks are a sign of worn or damaged seals. If you notice any oil on the shock body, it’s important to replace the seals as soon as possible to prevent further damage.
  • Reassemble the shock carefully, ensuring that all seals are properly installed and aligned.

Customization and Optimization

The Super Deluxe Ultimate DH rear shock is highly customizable to suit a wide range of riders and conditions. Here are a few tips for optimizing the shock’s performance:

  • Air Pressure: Adjust the air pressure based on your riding style. For downhill racing, you may want a slightly higher pressure for better responsiveness, while a lower pressure may provide more comfort on technical descents.
  • Rebound Settings: Set the rebound damping according to your preference. Faster rebound settings can make the shock feel more agile, while slower settings provide more control over rough terrain.
  • Compression Settings: Experiment with different compression settings to find the ideal balance between comfort and control. Higher compression settings provide more support, while softer settings allow for more movement and comfort.

Compatibility with Other Drivetrain Components

The Super Deluxe Ultimate DH rear shock is compatible with a variety of downhill-specific frames. However, it’s essential to verify that your bike’s frame and the shock are fully compatible. Check the following:

  • Mounting Type: Ensure that the shock’s eyelets match your bike’s frame design.
  • Shock Length and Stroke: Verify that the shock’s length and stroke match your bike’s geometry requirements. This will ensure proper handling and performance.
  • Spring Rate: The spring rate of the shock should be compatible with your weight and riding style. If you’re unsure, consulting the shock’s manual can help guide you to the correct spring rate.

By following these maintenance steps and optimizing your setup, you can ensure that your Super Deluxe Ultimate DH rear shock continues to perform at its peak [paid link], providing a smooth, controlled ride through the toughest terrain. Regular service and attention to detail will allow you to maximize the longevity and performance of your shock, ensuring that your bike is always ready for the next adventure.
