Posted on
in Uncategorized

The RockShox Super Deluxe Select [paid link]+ rear shock is a high-performance component that requires regular maintenance to ensure optimal function. One crucial aspect of maintaining the shock is performing an oil change. Over time, the oil inside the shock degrades and loses its effectiveness, which can lead to reduced performance, inconsistent damping, and an overall diminished ride experience. Performing an oil change on your Super Deluxe Select [paid link]+ will help maintain its longevity and performance.

This guide will take you through a step-by-step process to change the oil in your Super Deluxe Select+ rear shock, ensuring it remains in top condition for your rides.

Tools Required

  • 5mm Allen wrench [paid link]
  • 10mm Allen wrench [paid link]
  • T25 Torx wrench [paid link]
  • Shock pump
  • Oil syringe or syringe with hose (for precise oil measurement)
  • Small flathead screwdriver
  • RockShox suspension fluid (as specified in the owner’s manual)
  • Shock grease (for seals)
  • Clean rag or towel
  • Seal kit (if necessary)
  • Torque wrench [paid link]

Preparation for the Oil Change

Before you begin the oil change process, ensure that your Super Deluxe Select+ rear shock is completely clean and free from dirt. Any contamination during the disassembly process can affect the shock’s performance once reassembled. It’s also a good idea to work in a clean environment, such as a bike stand [paid link], to keep everything organized.

1. Remove the Rear Shock from the Bike

To begin, the rear shock needs to be removed from the bike frame. Follow these steps:

  • Use a 5mm Allen wrench to unscrew the bolts securing the shock to the bike frame.
  • Gently slide the shock off the mount, ensuring that you do not damage any of the bushings or mounts.

2. Place the Shock in a Secure Position

Place the shock on a clean towel or workbench to keep it stable during the oil change process. This step ensures that the shock remains stationary as you proceed with disassembly.

Disassembly of the Super Deluxe Select+

The next step involves disassembling the shock to access the internal oil chamber. This process requires careful attention to detail, as the internal components are sensitive and should be handled with care.

3. Remove the Air Sleeve

  • Use a 10mm Allen wrench to unscrew the air sleeve of the Super Deluxe Select+.
  • Gently slide the air sleeve off the shock body. Be cautious not to damage any seals in the process.

4. Drain the Old Oil

Once the air sleeve is removed, the old oil will need to be drained:

  • Hold the shock in an upright position, with the damper side facing downwards.
  • Use a small flathead screwdriver to remove the Schrader valve (if applicable) and let any remaining oil drain out.
  • Carefully discard the old oil in a designated container, ensuring proper disposal.

5. Remove the Damper Cartridge

  • Using a T25 Torx wrench [paid link], carefully remove the damper cartridge from the shock body.
  • Pay attention to any seals or o-rings that are removed during this step, as these will need to be replaced with fresh seals during reassembly.

Cleaning and Inspection

Before proceeding to the next step, it is important to clean and inspect the shock to ensure everything is in good working order.

6. Clean All Components

  • Wipe down all the internal and external parts of the shock using a clean rag or towel.
  • Inspect the shock shaft, damper cartridge, and air sleeve for any signs of damage, corrosion, or wear. If any damage is noted, it is essential to replace the affected part before reassembling the shock.

7. Check Seals and O-Rings

Inspect the seals and o-rings for signs of wear or damage. Replacing old or worn seals is critical to maintaining proper shock performance and preventing air and oil leaks. If necessary, replace all seals with a new seal kit.

Reassembly and Oil Filling

Now that the shock has been cleaned and inspected, you can begin reassembling it and filling it with fresh oil.

8. Install the Damper Cartridge

  • Place the damper cartridge back into the shock body, ensuring it is properly aligned.
  • Secure the cartridge with the T25 Torx wrench, ensuring it is torqued to the manufacturer’s specified torque setting.

9. Fill the Shock with Oil

  • Using a syringe or oil syringe, carefully fill the shock with the appropriate RockShox suspension fluid. Follow the fluid specifications in the owner’s manual to ensure you are using the correct oil.
  • Fill the shock body to the recommended fluid level, as indicated in the manual.
  • Once the correct amount of oil is added, gently cycle the shock to ensure the oil reaches all necessary areas.

10. Reinstall the Air Sleeve

  • Before reinstalling the air sleeve, apply a small amount of shock grease to the seals and o-rings to ensure a smooth reassembly.
  • Carefully slide the air sleeve back onto the shock body and screw it back into place using the 10mm Allen wrench.

Final Setup and Testing

11. Reinstall the Shock on the Bike

Once the shock is fully reassembled, it’s time to reinstall it back onto the bike frame:

  • Carefully align the shock’s mounting holes with the frame’s shock mount.
  • Secure the shock using the 5mm Allen wrench and tighten to the specified torque setting.

12. Set the Correct Air Pressure

  • Use a shock pump to set the air pressure to the desired level, based on the rider’s weight and preferred ride characteristics.
  • Double-check the air pressure after installation to ensure it remains stable.

13. Test the Shock

Finally, test the shock by compressing it by hand or taking a short ride. Check for any signs of leakage or unusual sounds. If everything functions as expected, the oil change is complete.

Troubleshooting Common Oil Change Issues

While performing an oil change on your RockShox Super Deluxe Select+, you may encounter a few issues. Here are some common problems and solutions:

1. Shock Is Still Leaking After Reassembly

If you notice oil leaking from the shock after reassembly, ensure that all seals are properly installed and that no debris was trapped in the seals during the cleaning process. If the issue persists, replace the seals and check for any damage to the shock body.

2. Shock Isn’t Holding Air Pressure

If the shock is not holding air pressure after the oil change, double-check that the Schrader valve is properly installed and not damaged. You may also need to replace the valve core if it’s worn.

3. Shock Feels Sticky or Doesn’t Compress Smoothly

If the shock feels sticky or doesn’t compress smoothly, it may be due to improper oil levels or contaminated oil. Ensure you’ve used the correct amount of fluid and that no contaminants were introduced during the oil change process.

Conclusion

Performing a rear shock oil change on your RockShox Super Deluxe Select+ is an essential part of maintaining its performance and longevity. By following the detailed steps outlined in this guide, you can ensure that your shock continues to perform at its best, providing a smooth and responsive ride. Regular oil changes, along with proper maintenance and inspection, will help you get the most out of your suspension system.
