The Cane Creek DBair CS [paid link] rear shock is renowned for its performance, especially when it comes to its Climb Switch feature, which provides enhanced climbing efficiency by firming up the suspension. However, like all suspension components, it requires regular maintenance to ensure it continues to perform at its best. In this guide, we will walk you through how to service your DBair CS [paid link] rear shock on your own.
Tools Required
- 10mm and 8mm Allen wrenches [paid link]
- Shock pump (with a pressure gauge)
- Torque wrench [paid link]
- Cane Creek service kit for DBair CS
- Clean rags or towels
- Latex gloves (optional)
- Suspension fluid (appropriate for DBair CS)
- Sealant or grease (as recommended by Cane Creek)
- Small flathead screwdriver or pick tool
- Soft brush for cleaning
Preparation
Before beginning any work on your DBair CS rear shock, it’s important to properly prepare the shock and your workspace. Start by ensuring your bike is securely mounted, and the shock is detached from the frame. This ensures you can work with the shock in a stable and comfortable position.
- Remove the Shock from the Frame
Using your 8mm and 10mm Allen wrenches [paid link], loosen the mounting bolts on the shock and carefully remove it from the frame. Make sure to keep track of any washers or spacers that may be used with the bolts. - Clean the Shock
Use a clean rag or towel to wipe down the shock. It’s essential to remove dirt, grime, and any excess grease before beginning the service. A soft brush can be helpful in cleaning areas that are harder to reach.
Disassembly and Inspection
With the shock removed and cleaned, it’s time to begin disassembling it. Proper inspection during this step will help you determine if any parts need replacement or if everything is in working order.
- Remove the Air Sleeve
The first step in disassembly is to remove the air sleeve, which houses the air spring. Use the correct tools from your Cane Creek service kit to carefully detach the sleeve. Inspect both the sleeve and the air can for any signs of damage or excessive wear. - Inspect the Internal Components
With the air sleeve removed, check the internal components for any signs of wear or damage. Pay close attention to the o-rings and seals. If they appear worn or damaged, they will need to be replaced. - Check the Damper Cartridge
The damper is a key part of the DBair CS shock. You should inspect the damper for any signs of oil leakage or damage. If you notice any issues, the damper may need to be serviced or replaced. - Check the Climb Switch Mechanism
Since the DBair CS features a Climb Switch, it’s essential to ensure that this mechanism is functioning correctly. Gently engage and disengage the switch, making sure it operates smoothly without sticking or excessive force.
Replacing Seals and O-Rings
If your inspection reveals any damaged seals or o-rings, they must be replaced. Use the seals and o-rings included in the Cane Creek service kit.
- Remove Old Seals and O-Rings
Carefully remove any old seals or o-rings using a pick tool or small flathead screwdriver. Be cautious not to scratch the metal surfaces of the shock while removing these parts. - Install New Seals and O-Rings
Lubricate the new seals and o-rings with a small amount of suspension fluid or recommended grease. Install them one by one, ensuring each is seated properly in its groove. Take your time with this step, as the quality of the seal installation directly impacts the performance and longevity of your shock.
Reassembly
Once all the necessary parts have been inspected and any damaged components have been replaced, it’s time to reassemble the shock. This step requires attention to detail to ensure everything is properly torqued and sealed.
- Reinstall the Air Sleeve
Carefully slide the air sleeve back into place. Ensure that all o-rings are in position and that the sleeve is securely attached to the body of the shock. Tighten any screws or bolts, following the torque specifications outlined in the Cane Creek manual. - Reassemble the Damper and Internal Components
Reinstall the damper and any other internal components, making sure everything is properly aligned. This is crucial for ensuring that the shock operates smoothly when under pressure. - Refill Suspension Fluid
Once the shock is reassembled, it’s time to refill the shock with the appropriate suspension fluid. Follow the manufacturer’s recommendations for the type and amount of fluid to use. Make sure to use the correct fluid for the DBair CS to maintain optimal performance.
Reinstalling the Shock
Now that the shock is fully serviced, it’s time to reinstall it on your bike. Ensure that the mounting bolts are clean and free of debris.
- Reattach the Shock to the Frame
Position the shock in the frame mounts and carefully tighten the mounting bolts. Be sure to use a torque wrench [paid link] to tighten the bolts to the proper specification. This ensures that the shock is securely mounted and reduces the risk of damage. - Reinflate the Shock
Using a shock pump, carefully inflate the DBair CS rear shock to the recommended pressure. Check the manufacturer’s guidelines for the ideal pressure based on your rider weight and the desired ride characteristics. Over- or under-inflating can negatively affect the shock’s performance. - Check for Leaks
Before fully finishing up, check for any air leaks around the air valve and air can. If you notice any leaks, remove the air and reseat the valve core. Check the seals to ensure they are properly seated.
Troubleshooting Common Issues
Even after servicing the DBair CS, you might encounter some issues. Below are some common troubleshooting tips:
- Shock Not Holding Air
If the shock loses air pressure quickly, the cause may be a damaged seal or o-ring. Inspect the seals again and replace them if necessary. - Shock Feels Too Soft or Too Firm
If the shock feels too soft or firm, check the air pressure and adjust it according to your weight and riding style. If the Climb Switch isn’t engaging or disengaging properly, inspect the switch mechanism for any signs of wear. - Climbing Switch Not Engaging Smoothly
If the Climb Switch sticks or doesn’t engage properly, there may be dirt or debris in the mechanism. Clean the switch area thoroughly, and lubricate it lightly with suspension fluid.
Customization and Optimization for Better Performance
The Cane Creek DBair CS rear shock offers multiple ways to adjust and customize the ride feel, especially with the Climb Switch.
- Adjust the Air Pressure
Fine-tune the shock’s air pressure to match your riding style. Lower pressure offers a more plush feel for aggressive downhill riding, while higher pressure provides more support for climbing. - Tune the Rebound and Compression Damping
Use the rebound and compression adjusters on the shock to tailor the suspension to your needs. The rebound controls the rate at which the shock extends after compression, while the compression damping affects the shock’s resistance to compression. - Optimize Climb Switch Settings
Adjust the Climb Switch for the perfect balance between efficiency and comfort. You may find that a slightly firmer setting helps with climbing while still maintaining sufficient comfort on rough terrain.
Compatibility with Other Drivetrain Components
The DBair CS rear shock is designed to work with a wide range of mountain bike components, but it’s important to ensure compatibility with your other drivetrain components, such as the rear triangle and shock mounting hardware.
- Check Mounting Hardware Compatibility
Make sure that your shock’s mounting hardware is compatible with your frame. Cane Creek offers a range of mounting kits that allow you to fit the DBair CS shock on various frame types. - Consider Your Bike’s Suspension Design
Some bikes may have specific requirements for suspension, especially regarding rear shock length and stroke. Be sure to check that the DBair CS matches the design of your bike’s rear suspension system.
By following these steps, you can keep your Cane Creek DBair CS rear shock functioning optimally without the need for a mechanic. Regular maintenance and attention to detail will ensure your shock continues to provide top-notch performance on every ride.
