Installation of the DBair CS Rear Shock
Installing the DBair CS rear shock is a straightforward process that requires careful attention to detail to ensure proper functionality and safety.
- Remove the Old Shock
Before installing the DBair CS, remove the old shock from your bike. Use the appropriate Allen wrenches [paid link] to loosen the bolts securing the shock to the frame. Make sure to keep the bolts in a safe place for reinstallation. - Inspect the Frame Mounts
Check the frame shock mounts for any damage or wear. Clean the mount surfaces thoroughly with a rag to remove any dirt or debris that could interfere with the new shock installation. - Install the DBair CS Shock
Position the DBair CS rear shock into the frame’s mounting points. Insert the upper and lower mounting bolts into their respective holes. Tighten the bolts by hand before using a torque wrench [paid link] to secure them to the manufacturer’s specified torque setting (usually 20Nm). - Pump the Shock to Desired Pressure
Use a shock pump to inflate the DBair CS to the correct air pressure, based on your weight and riding style. Refer to the Cane Creek recommendation guide for the proper air pressure range for your setup. - Check for Play and Proper Fitment
Once the shock is installed, check for any unwanted movement or play at the shock’s mounting points. If everything is secure, proceed to the next step. - Final Inspection
Conduct a final inspection of all bolts to ensure they are torqued correctly and that no parts are loose. Test the suspension by pushing down on the rear end of the bike to check for proper compression and rebound movement.
Adjustment and Tuning for Optimal Performance
The DBair CS rear shock provides several key adjustments that allow riders to fine-tune the shock for various riding conditions. Understanding how to adjust these settings is essential for optimizing performance.
1. Rebound Adjustment
- The rebound setting controls how quickly the shock returns to its original position after compression. To adjust rebound, locate the rebound knob on the shock and turn it to either increase or decrease the rebound speed.
- Faster Rebound: Turn the knob counterclockwise to allow the shock to return more quickly.
- Slower Rebound: Turn the knob clockwise to slow down the return of the shock.
The optimal rebound setting is usually where the shock returns just fast enough to keep the tire in contact with the ground without bouncing.
2. Compression Adjustment
The compression adjustment affects how the shock responds to initial hits and rough terrain.
- Low-Speed Compression: This controls the shock’s response to small, low-speed impacts such as pedal strikes or small bumps. Adjust this knob to make the shock stiffer for a more efficient ride or softer for more comfort.
- High-Speed Compression: This controls the shock’s response to larger, faster impacts. Dial this knob in for better control on high-speed sections of your trail, particularly when hitting big drops or g-outs.
3. Air Pressure
Setting the correct air pressure is crucial for maintaining proper suspension performance. As mentioned earlier, adjust the air pressure based on your weight and riding style. Cane Creek provides guidelines to help you determine the ideal pressure, but it’s important to experiment and find what works best for you.
4. Climb Switch (CS)
The DBair CS features a Climb Switch that provides a firm platform for climbing, reducing unwanted suspension movement while pedaling. When activated, the Climb Switch reduces rear shock movement, improving pedaling efficiency on steep climbs. To adjust the firmness of the Climb Switch, rotate the knob on the shock until you reach the desired level of firmness.
Maintenance and Care for DBair CS Rear Shock
Regular maintenance is essential for ensuring the longevity and performance of the DBair CS rear shock. Follow these steps to keep your shock in optimal condition.
1. Cleaning
Clean the shock after every ride, especially if you have been riding in muddy or wet conditions. Use a damp cloth to wipe down the shock body and remove dirt, grime, or moisture from the shock’s exterior. Be careful not to get any cleaning solution in the shock’s eyelet or seals.
2. Lubricating the Shock
Apply a thin layer of suspension grease or anti-seize compound to the shock mounting points before installation. This helps prevent creaking and wear on the frame and shock.
3. Air Can Service
The air can should be serviced periodically to ensure that the air chamber remains clean and free from contaminants. Cane Creek recommends servicing the air can every 50 hours of riding, but this may vary depending on your riding conditions.
- Remove the Air Can: Use a shock pump to release the air pressure, then remove the air can from the shock body.
- Clean the Components: Clean the air can, shaft, and seal head with a soft cloth.
- Reassemble: After cleaning, reassemble the shock and add the necessary oil and grease to the parts before reinstalling the air can.
4. Full Service
A full shock service, including oil changes and internal cleaning, should be done every 100-150 hours of riding. This service can be performed by a professional mechanic or at a Cane Creek-authorized service center.
Troubleshooting Common DBair CS Issues
1. Lack of Rebound or Compression Adjustment
If you notice that adjusting the rebound or compression does not seem to change the shock’s performance, it could indicate an issue with the internal damper. This might require a professional service to inspect the shock and replace worn components.
2. Suspension Bottoms Out Too Easily
If the shock bottoms out frequently, it may be an indication that the air pressure is too low or the compression settings are too soft. Try increasing the air pressure or adjusting the compression settings to firm up the shock.
3. Unusual Noises
If you hear any knocking, squeaking, or grinding sounds coming from the shock, it could be due to dirt in the shock’s seals or lack of lubrication. Clean the shock and lubricate the mounting points as necessary.
Comparison with Similar Models
The DBair CS rear shock competes with other high-performance shocks such as the RockShox Super Deluxe and Fox Float X2. Here’s how the DBair CS compares to these models:
- Adjustability: The DBair CS offers more precise tuning adjustments compared to the Fox Float X2, particularly with its Climb Switch and customizable compression settings.
- Weight: The DBair CS is slightly heavier than the RockShox Super Deluxe, making it better suited for riders who prioritize performance over weight savings.
- Price: The DBair CS is generally priced higher than the Super Deluxe but offers more comprehensive adjustment options, which can justify the added cost for riders looking for maximum customization.
Compatibility with Drivetrain Components
The DBair CS is compatible with most modern mountain bike drivetrains, but it is essential to consider factors such as the bike frame design and suspension linkage when pairing it with other components. Ensure that the shock’s eyelet size and stroke length are compatible with your frame’s geometry to avoid any installation issues. Additionally, the shock’s performance can be optimized when paired with compatible drivetrain components, such as the right gearing ratio and crankset for your intended use.
