The RockShox Kage RC rear shock is a high-performance suspension component designed for downhill and aggressive trail riding. Built to handle rugged terrain while maintaining control and comfort, the Kage RC stands out due to its adjustability, reliability, and ease of use. This guide will take an in-depth look at the Kage RC’s installation, adjustment, maintenance, troubleshooting, and compatibility considerations to ensure it performs optimally.

Installation of the Kage RC Rear Shock

Installing the RockShox Kage RC rear shock requires precision to ensure its performance and longevity. Here’s a step-by-step guide for proper installation.

Tools Required:

• 5mm Allen wrench [paid link]
• Torque wrench [paid link]
• Suspension pump (for setting air pressure)
• Shock mounting hardware (provided with the shock)
• Soft cloth (to prevent damage during handling)

Installation Steps:

1. Prepare the Bike Frame: Begin by ensuring the frame is clean and free from debris. This will prevent any dirt or grime from contaminating the suspension components.
2. Remove the Old Shock: If replacing an old shock, use a 5mm Allen wrench [paid link] to remove the mounting bolts securing the previous shock. Carefully detach the shock from the frame.
3. Install the New Shock: Place the Kage RC shock into the frame’s shock mount. Make sure it aligns with the mounting holes on both ends of the shock.
4. Secure the Shock: Using the provided mounting hardware, secure the shock to the frame. Tighten the bolts using a torque wrench [paid link] to the manufacturer’s recommended torque value (typically between 30-35 Nm).
5. Set the Air Pressure: Use a suspension pump to set the air pressure. Refer to the RockShox manual for the correct pressure based on rider weight and intended use.
6. Final Checks: Double-check all bolts for proper torque and ensure the shock is securely mounted.

Adjustment of the Kage RC Rear Shock

One of the key features of the Kage RC rear shock is its adjustability. Fine-tuning the shock settings allows riders to tailor their suspension performance to their riding style and terrain. The Kage RC includes a few essential adjustment features:

Rebound Damping Adjustment

The Kage RC features a rebound damping knob that allows riders to control the rate at which the shock returns after compression. To adjust rebound:

• Turn the knob clockwise to slow down rebound (for smoother, more controlled landings).
• Turn the knob counterclockwise to speed up rebound (for more responsive, lively handling).

Compression Damping Adjustment

The Kage RC offers external compression adjustment, which controls the shock’s resistance to compression under load. To adjust compression damping:

• Turn the compression knob clockwise for firmer suspension (ideal for aggressive riding and heavy impacts).
• Turn the compression knob counterclockwise for a softer, more plush feel (better for lighter riders or less aggressive terrain).

Air Spring Pressure

The Kage RC uses an air spring system, which allows for easy tuning by adjusting the air pressure. The correct pressure depends on your weight and riding style. A higher pressure provides a firmer ride, while a lower pressure gives a more supple suspension.

Maintenance of the Kage RC Rear Shock

Regular maintenance is crucial for ensuring the longevity and optimal performance of your Kage RC rear shock. Here’s how to keep your shock in top condition:

Cleaning

• Routine Cleaning: After each ride, wipe down the shock with a soft cloth to remove dirt, mud, and debris. This prevents contaminants from entering the seals and causing wear.
• Seal Care: Occasionally clean the shock’s seals by gently wiping them with a damp cloth. Avoid harsh chemicals that could damage the seals.

Rebuilding the Shock

While the Kage RC is designed for durability, periodic servicing is necessary to maintain performance:

• Oil Changes: RockShox recommends servicing the Kage RC every 50-100 hours of riding, depending on use. This includes replacing the internal oil to maintain damping performance.
• Seal Replacement: The seals in the Kage RC should be replaced every 150-200 hours of riding or whenever you notice a decrease in performance. This will prevent air and oil leaks, ensuring the shock operates smoothly.

Air Spring Recharging

The air spring requires occasional recharging as it loses pressure over time. Check the air pressure before every ride and adjust it according to your body weight and riding conditions.

Troubleshooting Common Set-Up Issues

While the Kage RC is a reliable rear shock, there are common issues that riders may encounter. Here’s how to troubleshoot and resolve them:

Shock Not Returning Quickly

If the shock feels slow to return to its normal position, the rebound damping setting may be too slow. Increase the rebound speed by turning the rebound knob counterclockwise.

Bottoming Out

If the shock bottoms out during impacts, the air pressure may be too low. Increase the air pressure to ensure the shock has adequate support. You may also want to check the compression damping and adjust it to a firmer setting if necessary.

Noisy Shock

If the shock is making unusual noises, check the mounting hardware for tightness. Loose bolts can cause rattling. Also, inspect the shock seals for damage, as worn seals can lead to air and oil leaks, causing performance issues.

Customization and Optimization for Better Performance

The Kage RC rear shock can be customized to improve performance for specific riding styles and terrain. Here are some tips for optimizing the shock:

Tuning for Downhill Riding

• Increase Air Pressure: For downhill riding, increase the air pressure to prevent bottoming out on big impacts.
• Firm Compression Damping: Turn the compression knob to a firmer setting to reduce excessive movement and maintain stability during high-speed descents.

Tuning for Enduro and Trail Riding

• Slightly Lower Air Pressure: Reduce the air pressure to improve small bump compliance and comfort on technical trails.
• Mid-Range Compression: Set the compression damping to a balanced setting to offer both comfort and support on mixed terrain.

Compatibility with Other Drivetrain Components

The Kage RC rear shock is compatible with most modern mountain bike frames, especially those designed for aggressive riding. However, it’s essential to ensure compatibility with your bike’s frame, including:

• Shock Mounting Specifications: Ensure that your frame supports the shock’s eyelet and stroke length. The Kage RC comes in various sizes, so check your frame’s specifications for proper fit.
• Linkage and Suspension Design: Some bike frames feature specific linkage designs that may affect how the shock interacts with the frame. Be sure to consult your bike’s manual for compatibility with the Kage RC.

Comparison with Similar Models

The Kage RC rear shock is a robust option for riders looking for a reliable, adjustable rear shock. Here’s how it compares to other popular models:

RockShox Super Deluxe

• Adjustability: Both the Kage RC and Super Deluxe offer external rebound and compression damping, but the Super Deluxe has a more refined, higher-end damper system designed for more aggressive riders.
• Weight: The Kage RC is slightly heavier than the Super Deluxe, making it a better choice for riders prioritizing durability over weight savings.

Fox Float X2

• Performance: The Fox Float X2 offers more advanced compression and rebound adjustments, making it a better choice for riders seeking fine-tuned performance in extreme conditions.
• Price: The Kage RC is a more affordable option, making it a solid choice for riders who want high-quality performance without the premium price tag.
