  • Shock pump
  • 2.5mm Allen wrench
  • 2mm Allen wrench
  • Dust wipers (specific to Super Deluxe Ultimate RCT)
  • Silicone grease
  • RockShox service kit (specific to the model)
  • Rags
  • Bucket of water
  • Towel
  • Stanchion cleaner or isopropyl alcohol
  • Seal driver
  • O-ring grease

Preparation

Before starting the servicing process, ensure that you have a clean, well-lit workspace. It is also essential to have a clean cloth or towel to wipe down the shock components during the procedure. Having a shock pump ready is important for recharging the shock to the appropriate pressure once the service is complete.

Removal of the Shock

The first step is to remove the Super Deluxe Ultimate RCT rear shock from your bike:

  1. Detach the Shock from the Frame: Use a 5mm Allen wrench to remove the bolts that attach the shock to the bike frame. Take note of the orientation of the shock and any washers or spacers in place.
  2. Support the Shock: Gently remove the shock, supporting it as you take it off the bike. Be careful not to damage the shock or surrounding components during this process.

Cleaning the Shock

With the shock removed, it’s time to clean it thoroughly:

  1. Wipe Down the Shock Body: Using a clean rag, carefully wipe down the shock body and stanchion. Be sure to remove any dirt or debris from the surface to prevent contamination when opening the shock.
  2. Clean the Shock’s Stanchion: Spray the stanchion with stanchion cleaner or isopropyl alcohol to remove grease and grime. This step is crucial for maintaining smooth suspension performance and preventing wear on the seals.

Disassembling the Super Deluxe Ultimate RCT

Now that the shock is clean, you can begin disassembling it for a more in-depth service:

  1. Remove the Eyelet Bolts: Use an 8mm Allen wrench to unscrew the eyelet bolts. These bolts hold the shock’s body together and must be carefully removed.
  2. Take Off the Shock’s Canister: Once the eyelet bolts are removed, gently slide the shock canister off the main body of the shock. This will expose the inner components, such as the damper and air spring system.

Inspecting and Replacing Components

With the shock disassembled, take the time to inspect all components for wear or damage:

  1. Check the Shock Seals: Inspect the seals and wipers for wear or tears. If the seals are damaged, it’s essential to replace them to ensure proper damping performance.
  2. Inspect the Damper: Examine the damper for signs of leakage or damage. If you notice any oil stains or irregularities, it’s likely time to replace the damper assembly.
  3. Check the Air Spring: If your Super Deluxe Ultimate RCT features an air spring, check the air can for any damage. If you find any punctures or deformities, replace the air spring assembly.
  4. Examine the Internal Components: Look over the other internal components, such as the piston and rebound adjuster, to make sure they are intact and functioning properly.

Rebuilding the Shock

Now it’s time to rebuild your rear shock with new seals and any replacement parts:

  1. Install New Seals: Apply silicone grease to the new seals and install them carefully into the shock body and canister. This step is important to prevent air or fluid leaks and ensure smooth operation.
  2. Replace the O-rings: O-rings are critical for maintaining air pressure and fluid sealing. Lubricate and replace all O-rings inside the shock and on the damper assembly.
  3. Reassemble the Shock: Carefully slide the shock canister back onto the shock body, ensuring all parts are aligned correctly. Tighten the eyelet bolts using a torque wrench [paid link] to ensure they are properly secured. Follow the manufacturer’s recommended torque settings to avoid damaging any parts.

Recharging and Reinstalling the Shock

Once your shock has been reassembled and any worn parts replaced, it’s time to recharge the air spring and reinstall the shock onto your bike:

  1. Pump the Shock to the Correct Pressure: Using a shock pump, recharge the shock to the correct pressure as per your weight and riding style. The recommended pressure is usually printed on the shock or in the owner’s manual.
  2. Reinstall the Shock: Position the shock back onto the frame of your bike, making sure the orientation is correct. Reinstall the eyelet bolts and torque them to the proper settings.
  3. Check for Leaks: Before taking your bike for a test ride, ensure that there are no air leaks by checking the shock’s seals and pressure gauge.

Fine-Tuning and Performance Optimization

After servicing your Super Deluxe Ultimate RCT rear shock, it’s important to fine-tune it for your specific riding style:

  1. Adjust the Rebound: Use the rebound adjustment knob to fine-tune the shock’s response. Depending on your riding style, you may want to increase or decrease the rebound damping for smoother or quicker returns.
  2. Check Compression Settings: If your shock has adjustable compression settings, tweak them to suit your needs. A higher compression setting provides a firmer ride, while a softer setting allows more flexibility for rough terrain.

Troubleshooting Common Issues

While servicing your Super Deluxe Ultimate RCT rear shock, you may encounter certain issues that require troubleshooting:

  1. Leaking Shock: If you notice fluid leaking from the shock, it may be due to worn seals or a damaged damper. Inspect and replace any faulty components.
  2. Sag Issues: If the shock feels overly saggy or stiff, check the air pressure and adjust it according to your weight and riding preferences.
  3. Rebound or Compression Issues: If the rebound or compression damping feels inconsistent, it may indicate an internal issue with the damper or air spring. Disassemble the shock, inspect for damage, and replace any necessary parts.

Conclusion

Regular maintenance and servicing of your Super Deluxe Ultimate RCT rear shock are essential to ensure optimal performance and longevity. By following this guide, you can easily service your shock yourself, saving both time and money. Regular inspection, cleaning, and replacement of worn components will help keep your rear shock functioning at its best, providing a smoother and more responsive ride.
