It stands out for its dual-volume air spring and innovative damper technology, designed to improve handling and comfort on both cross-country and enduro mountain bikes. The shock features Cane Creek’s renowned DB (Double Barrel) damper, which offers independent high- and low-speed compression and rebound adjustments for fine-tuning suspension feel.
Key Features of the DB Kitsuma Air:
- Dual-Volume Air Spring: Allows for better tuning of the shock’s performance.
- Dual Adjustments: Independent adjustments for high-speed and low-speed compression and rebound.
- Premium Build Quality: Engineered for durability and long-lasting performance.
- Performance-Optimized Damper: Helps manage heat dissipation and reduces the chances of fade during long descents.
Installation of the DB Kitsuma Air
Installing the DB Kitsuma Air on your mountain bike requires some technical skill. It is important to follow precise steps to ensure the shock is properly aligned and securely mounted.
Tools Required:
- Torque wrench [paid link]
- 8mm and 10mm Allen wrenches [paid link]
- Shock pump
- Suspension grease
- Clean cloth
- Ruler or caliper for measuring eyelet length
Installation Steps:
- Prepare the Bike: Ensure your bike is on a stable stand and remove any components obstructing access to the rear shock (e.g., saddle or rear wheel if necessary).
- Remove the Old Shock: Loosen the bolts securing the old shock and remove it from the frame. Clean the shock mount areas to remove any dirt or debris.
- Install the New Shock: Insert the DB Kitsuma Air into the rear triangle, ensuring the eyelets match the mounting points on the frame.
- Tighten Bolts: Secure the shock with the appropriate bolts and torque them according to the manufacturer’s specifications to prevent over-tightening. Use a torque wrench [paid link] for precision.
- Set Sag: Using a shock pump, inflate the air chamber to the recommended pressure and check the shock’s sag. Adjust the pressure to achieve the correct sag for your weight.
- Reassemble and Test: Once installed, reassemble any removed parts (e.g., rear wheel) and perform a test ride to verify that the shock is functioning correctly.
Adjustment and Tuning
The DB Kitsuma Air is highly adjustable, allowing riders to fine-tune both compression and rebound for optimal performance. The shock has two primary adjustments: the high-speed and low-speed compression, as well as the rebound settings.
Compression Adjustments:
- High-Speed Compression: Adjusts how the shock responds to rapid impacts such as large drops or fast hits. Higher settings provide more resistance, reducing bottoming out.
- Low-Speed Compression: Affects how the shock responds to slower compressions, like pedaling forces. This adjustment impacts the bike’s ride feel when climbing or pedaling on smooth terrain.
Rebound Adjustments:
- Rebound Damping: Controls the speed at which the shock returns to its original position after compression. Adjusting the rebound ensures a smooth and controlled return, preventing the shock from bouncing excessively.
Fine-Tuning Tips:
- Start with the manufacturer’s recommended settings and adjust incrementally.
- Test the shock after every adjustment and make small changes until you find the optimal balance between comfort and control.
- Pay attention to ride characteristics and adjust both the compression and rebound settings to suit different terrain types.
Maintenance of the DB Kitsuma Air
To ensure the longevity and performance of the DB Kitsuma Air, regular maintenance is essential. Proper care will help maintain optimal suspension performance and prevent premature wear.
Regular Cleaning:
- Clean the Shock Body: After each ride, wipe down the shock with a clean, damp cloth to remove dirt and debris. Keep the shock free from mud and grime to avoid damaging seals and components.
- Lubricate the Shock: Apply suspension grease to the shock’s mounting hardware to prevent corrosion and ensure smooth operation.
Air Pressure Maintenance:
- Periodically check the air pressure in the shock using a shock pump. Over time, air can slowly leak, which can lead to improper sag settings and suboptimal performance. Adjust the air pressure as necessary.
Damper Maintenance:
- The DB Kitsuma Air’s damper should be serviced periodically. Cane Creek recommends having the damper serviced every 150 hours of riding. During the service, the oil inside the damper is replaced to ensure consistent damping performance.
Seal Replacement:
- Over time, the seals on the shock may wear out. Replacing seals as needed will prevent air and oil leakage and ensure smooth operation.
Troubleshooting Common Issues
1. Excessive Rebound:
- If the shock is bouncing excessively after compression, adjust the rebound setting. Turn the knob counterclockwise to slow the rebound speed and prevent the shock from bouncing too fast.
2. Bottoming Out:
- If the shock bottoms out too often, increase the high-speed compression setting to provide more resistance during aggressive hits.
3. Lack of Sag:
- If you’re not achieving the correct sag, check the air pressure in the shock. Increase the pressure if you’re getting too much sag, or decrease it if you’re getting too little.
Customization and Optimization for Better Performance
The DB Kitsuma Air offers a range of customization options to match your riding style and terrain. Optimizing the shock for your specific needs can drastically improve your mountain biking experience.
- Adjust the Air Spring: Use the dual-volume air spring to adjust the shock’s spring rate. You can switch between different air volume spacers to tailor the shock’s response to suit your weight and riding style.
- Tune Compression and Rebound for Terrain: Fine-tuning the shock to match the type of terrain you ride on—whether it’s aggressive downhill or technical cross-country trails—will provide the best balance of performance and comfort.
Comparison with Other Rear Shocks
When comparing the DB Kitsuma Air to other rear shocks on the market, it stands out for its extensive adjustability and smoothness on aggressive terrain. Here are some factors to consider when comparing it to similar models:
Fox Float X2:
- The Fox Float X2 is known for its plush feel and wide range of adjustment options, but it may not offer as much low-speed compression control as the DB Kitsuma Air.
- The DB Kitsuma Air’s dual-volume air spring allows for more customization in terms of spring rate, while the Float X2 is known for being more of a “set-and-forget” shock.
RockShox Super Deluxe:
- The RockShox Super Deluxe is another popular rear shock but tends to be less customizable than the DB Kitsuma Air. While it offers great performance, it lacks the granular control over both compression and rebound that the Kitsuma Air offers.
- The Kitsuma Air is better suited for riders who want to fine-tune their shock settings for every trail condition.
Compatibility with Other Drivetrain Components
The DB Kitsuma Air is compatible with most modern mountain bike frames and drivetrain systems, provided the shock’s eyelet size and stroke length match the specifications of the frame. It’s important to verify compatibility with your bike’s geometry before purchase to ensure seamless integration. The shock works well with both 1x and 2x drivetrains, and its adjustability complements a wide range of bike setups.
