Step-by-Step Rear Shock Oil Change for DBinline

The Cane Creek DBinline rear shock is a high-performance shock that requires regular maintenance to ensure its optimal performance. One essential maintenance task for the DBinline is the oil change, which ensures the shock operates smoothly and extends its lifespan. This step-by-step guide will walk you through the process of changing the rear shock oil on a DBinline, from disassembly to reassembly.

Tools Required

3mm, 5mm, and 8mm Allen wrenches [paid link]
Cane Creek DBinline shock tool (specific tool for disassembling the shock)
Torque wrench [paid link]
Clean workspace
Isopropyl alcohol or shock cleaner
Shock oil (Cane Creek-approved oil for DBinline)
Small container for old oil
New seals and O-rings (if necessary)
Plastic spatula or small pry tool
Shock pump

Preparing for the Oil Change

Before you begin, make sure you have all the necessary tools and components ready. It’s also important to set up a clean and well-lit workspace to avoid contaminating the shock with dirt or debris. Additionally, ensure the bike is stable by securing it in a work stand, especially when removing the shock from the frame.

1. Remove the Rear Shock from the Bike

Start by releasing the rear shock from the bike frame. Use a 5mm Allen wrench [paid link] to unscrew the bolts holding the shock in place. Keep these bolts in a safe spot as you’ll need them for reinstallation.
Carefully remove the shock from the frame and place it on a clean surface. It is critical not to let dirt or dust contaminate the shock during this process.

2. Disassemble the Shock for Oil Access

Use the Cane Creek DBinline shock tool to begin the disassembly. The shock tool allows for safe disassembly by unscrewing the body from the reservoir.
Start by removing the top cap using the tool. The cap can be a bit tight, so be sure to turn it counterclockwise carefully.
Once the top cap is off, carefully detach the damper assembly from the body of the shock. The oil reservoir should now be exposed, and you’ll have access to change the oil.

3. Drain the Old Oil

With the damper assembly removed, place the shock upright over the container to collect the old oil. Allow it to drain completely for several minutes.
Gently tap the shock to ensure all oil drains out. The goal is to remove as much old oil as possible before adding fresh oil.

4. Clean All Components

Once the oil has been drained, clean all parts of the shock, including the damper, reservoir, and seals, using isopropyl alcohol or a shock-specific cleaner. This ensures that no residue or dirt remains that could affect performance.
Pay close attention to the seals, as any dirt or damage can cause oil leaks or poor performance.

5. Inspect and Replace Seals if Necessary

Inspect the seals and O-rings for signs of wear or damage. If they appear worn, replace them with new ones to prevent leaks and maintain performance.
Carefully remove the old seals and press the new ones into place using your fingers or a small plastic spatula. Be sure they are seated properly to avoid any future issues.

Adding New Oil to the DBinline Shock

6. Select the Correct Shock Oil

Cane Creek recommends using the specific oil for the DBinline rear shock to maintain its performance. Ensure that the oil is the correct weight and type as per the manufacturer’s specifications.

7. Fill the Reservoir with Fresh Oil

Slowly pour the recommended amount of oil into the reservoir. Be cautious not to overfill. The exact amount of oil can vary based on the model and tuning of your shock, so refer to the Cane Creek manual for the correct quantity.
Ensure that the oil completely covers the internal components but does not spill over the edge.

8. Reassemble the Shock

With the reservoir filled, carefully reassemble the damper and the shock body. First, align the damper into the shock body, ensuring it seats correctly without forcing it.
Once aligned, secure the top cap back in place using the Cane Creek DBinline shock tool. Tighten it to the manufacturer’s recommended torque specification. This ensures the oil is sealed inside and the shock operates efficiently.

Reinstalling the Shock

9. Reattach the Shock to the Bike Frame

Now that the shock is reassembled, it’s time to reinstall it on your bike. Align the shock with the mounting points on the frame and insert the bolts. Tighten them securely with your 5mm Allen wrench [paid link], ensuring the shock is stable and firmly in place.
Use a torque wrench [paid link] to tighten the bolts to the correct torque specification, which can usually be found in the Cane Creek manual or on the shock itself.

10. Check for Proper Functionality

After reinstalling the shock, use a shock pump to ensure the correct air pressure is set according to your riding weight and preferences.
Carefully cycle the shock by pushing down on the rear of the bike and releasing it. This allows you to check for smooth travel and confirms that no oil leaks have occurred.
If the shock feels sluggish or there’s any indication of air or oil leakage, disassemble and inspect the shock again for any errors in reassembly or seal issues.

Final Adjustments

11. Adjust the Compression and Rebound Settings

With the shock installed and functioning properly, adjust the compression and rebound settings based on your riding preferences and terrain.
Start with the manufacturer’s recommended settings and fine-tune them as necessary. Make small adjustments and test ride the bike to ensure the shock is responsive and comfortable.

12. Test Ride and Fine-Tuning

Once you’ve set the desired air pressure and damping adjustments, take the bike for a test ride. Pay close attention to how the shock behaves under different riding conditions.
If needed, make further adjustments to the compression or rebound settings until you achieve the ideal ride feel.

Troubleshooting Common Issues

13. Shock Feels Too Soft or Too Stiff

If the shock feels too soft, increase the air pressure slightly to firm up the ride. Conversely, if the shock feels too stiff, you may need to reduce the air pressure.
Also, check the rebound and compression settings, as incorrect adjustments can affect the shock’s responsiveness.

14. Oil Leaks

If you notice oil leaking from the shock, inspect the seals and O-rings. Any damage to these components will cause leaks, and they should be replaced immediately.
Ensure the shock was reassembled correctly, with no loose parts that might allow oil to escape.

15. Uneven Shock Travel

If the shock isn’t compressing or returning evenly, check for air in the shock. Air bubbles can form during the oil change process, and these can impede proper function.
Bleed the shock to remove any trapped air by cycling the shock or gently tapping it to allow air bubbles to escape.

By following these steps, you will have successfully changed the oil in your Cane Creek DBinline rear shock. Proper maintenance ensures that your shock performs at its best, helping you to ride smoother and with greater confidence. Regular oil changes are essential for keeping your shock in peak condition and maintaining a great ride experience.
