Installation of the DB Kitsuma Air Rear Shock
Installing the DB Kitsuma Air [paid link] Rear Shock on your bike requires careful attention to detail and proper torque settings to ensure safety and optimal performance. Here’s a step-by-step guide to follow:
- Remove the Old Shock
If you’re replacing an existing shock, use a 5mm or 6mm Allen wrench [paid link] to remove the bolts holding the shock in place. Ensure that you remove the shock carefully, without damaging the mounting hardware. - Prepare the Mounting Hardware
Before installing the new DB Kitsuma Air shock, check the mounting hardware on your bike. If it is worn or damaged, it’s a good idea to replace it. Cane Creek offers specific hardware kits for various bike models. - Align the Shock
Position the shock on the rear triangle of the bike, making sure the shock body aligns with the mounting points. Ensure the air canister is oriented according to the manufacturer’s specifications. - Secure the Shock
Insert the mounting bolts and tighten them using a torque wrench [paid link]. Check the bike’s manual for the exact torque specifications (usually between 8-12 Nm). Proper torque is essential for shock performance and to prevent any movement or failure. - Double-check the Positioning
After installation, make sure the shock is seated properly and the mounting bolts are secure. Test the movement by compressing the shock slightly to ensure there is no binding or misalignment.
Adjusting the DB Kitsuma Air Rear Shock
Once your DB Kitsuma Air Rear Shock is installed, adjusting it to your weight, riding style, and terrain is crucial for maximum performance. Here’s how to get the most out of your shock:
- Set the Air Pressure
Use a shock pump to adjust the air pressure in the shock’s main air chamber. The correct air pressure will depend on your weight and riding style. Start with the manufacturer’s recommended air pressure settings and make adjustments based on personal preference. The shock pump will allow you to increase or decrease pressure incrementally. - Rebound Adjustment
The rebound adjustment controls how quickly the shock returns to its original position after compression. To adjust, use a 2mm Allen wrench to turn the rebound dial located at the bottom of the shock. Turn it clockwise for a slower rebound and counterclockwise for faster rebound. Test the rebound by compressing the shock and releasing it; you should feel smooth and controlled rebound. - Compression Adjustment
The compression adjustment affects how the shock reacts to impacts and changes in terrain. The DB Kitsuma Air shock has high and low-speed compression adjustments. Use the 2mm Allen wrench to adjust the high-speed compression and turn the external dial to adjust the low-speed compression. Start with the recommended baseline settings and fine-tune them based on your preferences and the trail conditions. - Volume Spacers
If you’re looking to adjust the bottom-out resistance of the shock, adding or removing volume spacers can help. Volume spacers reduce the amount of air volume, which increases the ramp-up of the shock’s compression. For more aggressive riding, adding spacers will help prevent bottoming out.
Regular Maintenance and Service
Maintaining your DB Kitsuma Air Rear Shock ensures long-term performance and reliability. Here’s a maintenance schedule to follow:
- Cleaning the Shock
Regularly clean the shock after each ride, especially if riding in muddy or dusty conditions. Use a clean, damp cloth to wipe down the shock body. Pay attention to the seals and air canister area to prevent dirt and grime buildup, which could affect the performance. - Inspect the Seals
Check the shock’s seals for any visible damage or wear. If the seals appear cracked or compromised, they should be replaced. Proper sealing is essential for maintaining the shock’s air pressure and preventing oil leakage. - Change the Suspension Fluid
Suspension fluid should be replaced regularly to maintain smooth operation. Cane Creek recommends changing the fluid every 50-100 hours of riding or annually, whichever comes first. The fluid replacement process involves draining the old oil, cleaning the shock internals, and refilling it with fresh suspension fluid. Use Cane Creek’s recommended suspension fluid for optimal performance. - Air Pressure Check
Periodically check the air pressure in your shock using a shock pump. Over time, the air pressure can gradually drop, leading to suboptimal performance. Adjust it according to your weight and riding preferences.
Troubleshooting Common Set-Up Issues
Sometimes, despite the best efforts at installation and adjustment, issues may arise. Here are some common problems and how to troubleshoot them:
- Shock Bottoming Out
If the shock bottoms out too easily, the air pressure may be too low or the rebound damping may need adjustment. Try increasing the air pressure slightly and adjusting the rebound to a slower setting. - Shock Overheating
Overheating can occur during long, aggressive descents, causing the shock to lose performance. To mitigate this, adjust the compression settings to slow down the shock’s response to impacts and avoid high-speed compression settings. - Squeaking or Sticking Shock
If the shock feels sticky or emits squeaks, check the mounting bolts for tightness. If the shock body is not lubricated properly, the internal seals may cause resistance. Lubricating the seals and checking for any dirt or debris can help restore smooth operation.
Optimizing Performance for Better Ride Quality
Optimizing the DB Kitsuma Air Rear Shock for performance involves fine-tuning its settings to match your riding style and terrain. Here are some tips for getting the best performance:
- Adjust Air Pressure Based on Ride Style
Riders who frequently ride technical trails may benefit from a higher air pressure to avoid bottoming out, while those on smoother trails may prefer a lower pressure for a more plush ride. Experiment with different pressures to find the right balance. - Tune Compression Damping
Riders who prefer a firmer, more responsive ride should increase the low-speed compression damping. Conversely, riders who enjoy a smoother ride over rough terrain should dial back the compression to allow the shock to absorb more small bumps. - Monitor and Maintain
Regular monitoring of your shock settings ensures that you can adjust for any wear or changes in your riding style. Keep an eye on air pressure, fluid levels, and seal conditions to maintain optimal performance.
Compatibility with Other Drivetrain Components
The DB Kitsuma Air Rear Shock is designed to be compatible with a wide range of mountain bike frames and drivetrains. It is important to ensure the shock’s specifications match your frame’s requirements. Compatibility with the frame’s rear suspension design and clearance is crucial for ensuring proper functioning and safety. Always consult with the manufacturer or your local bike shop if you’re unsure whether the shock is compatible with your bike.
