• Durability: Constructed with Öhlins’ renowned engineering quality, the STX22 Coil Rear Shock is built to last. It can handle heavy impacts and provide consistent performance in various riding conditions.
• Improved Traction: Thanks to its advanced damping system, the STX22 ensures better traction and control, particularly when cornering or riding on uneven surfaces.
• Customization: Riders can select the appropriate coil spring rate based on their weight, riding style, and terrain, ensuring a personalized suspension setup.

Installation of the STX22 Coil Rear Shock

Installing the STX22 Coil Rear Shock requires a basic understanding of suspension components, but it’s a relatively straightforward process. Here’s a step-by-step guide to ensure a proper setup.

Tools Required:

• Torque wrench [paid link]
• Shock pump
• 8mm Allen key
• 5mm Allen key
• Compression tool for coil springs (if necessary)
• Lubricant

Installation Steps:

1. Remove the Old Shock: Using the appropriate size Allen key, remove the mounting bolts securing the existing rear shock. Carefully take out the shock from the mounting points.
2. Prepare the New STX22 Shock: Ensure that the STX22 shock is prepped with the correct spring rate for your weight and riding style. Install the coil spring if it is not pre-installed.
3. Mount the STX22 Shock: Position the new shock on the mounting points and align the eyelets with the frame’s shock mounts.
4. Secure the Shock: Tighten the mounting bolts to the recommended torque specification using a torque wrench [paid link]. Ensure both bolts are evenly tightened.
5. Set Up the Suspension Settings: Adjust the compression and rebound settings according to your preferences. Use the shock pump to set the appropriate air pressure or preload as recommended by Öhlins.
6. Check for Clearance and Functionality: Verify that the shock operates smoothly and that there is no interference with the bike frame or other components during full suspension compression.

Maintenance and Adjustment

Proper maintenance and periodic adjustments are critical for ensuring the longevity and performance of the STX22 Coil Rear Shock.

Regular Maintenance:

• Inspect the Shock: Regularly check the shock for any signs of wear or damage. Look for leaks around the seals and ensure the coil spring is in good condition.
• Clean the Shock: After each ride, clean the shock with a damp cloth to remove dirt and debris. Be cautious not to let any water seep into the shock body.
• Lubrication: Periodically lubricate the shock bushings to reduce friction and prolong the life of the shock.
• Check the Spring Rate: Ensure that the spring rate is suitable for your riding weight. If you experience bottoming out or lack of support, consider switching to a different coil spring.

Adjustment Tips:

• Compression Adjustment: Fine-tune the low-speed compression for smoother handling on rough terrain. If the ride feels too harsh, soften the compression, or increase it if you need more support.
• Rebound Adjustment: Adjust the rebound to control how quickly the shock returns after compressing. A slower rebound can help in rougher conditions, while a faster rebound works better for smoother rides.

Troubleshooting Common Issues

Like all high-performance suspension components, the STX22 Coil Rear Shock can experience certain issues over time. Below are some common problems and their solutions.

1. Too Soft or Too Stiff Suspension:

• Problem: If the suspension feels too soft or too stiff, it may indicate the wrong coil spring rate.
• Solution: Swap out the coil spring for one that matches your weight and riding style. Öhlins provides different spring rates to accommodate a wide range of riders.

2. Poor Rebound Control:

• Problem: If the shock rebounds too quickly or too slowly, it may be out of adjustment.
• Solution: Adjust the rebound setting using the designated dial or knob. Test different settings to find the optimal response.

3. Shock Bottoming Out:

• Problem: Bottoming out occurs when the shock compresses fully, often resulting in a harsh ride.
• Solution: Increase the spring rate or adjust the preload to provide more support for your weight and riding conditions.

4. Excessive Noise or Creaking:

• Problem: Noises from the shock are often caused by dirt or insufficient lubrication.
• Solution: Clean the shock and lubricate the bushings. If the noise persists, check the mounting bolts for tightness.

Customization and Optimization

The STX22 Coil Rear Shock is highly customizable, which allows riders to fine-tune the suspension for their specific needs. To optimize the performance of the shock, consider the following adjustments:

• Coil Spring Rate: Selecting the correct coil spring is crucial for maximizing comfort and control. Lighter riders may prefer a softer spring, while heavier riders or those riding more aggressively may require a firmer spring.
• Damping Settings: Fine-tuning the high- and low-speed compression and rebound settings can significantly improve your ride. Riders who often tackle downhill terrain may opt for a more aggressive compression setup, while those who ride on smoother surfaces might prefer a more compliant setting.
• Preload: Adjust the preload on the coil spring to set the sag (the amount of suspension compression under the rider’s weight). This ensures optimal suspension performance and comfort.

Compatibility with Other Drivetrain Components

The STX22 Coil Rear Shock is designed to work seamlessly with a wide range of drivetrain components. However, it’s essential to ensure compatibility with your bike’s frame and other suspension components, especially when upgrading from an older shock or installing it on a different bike model. Before installation, verify the following:

• Mounting Specifications: Ensure that the shock’s eyelet size and shock stroke are compatible with your frame.
• Suspension Design: The STX22 is compatible with various bike frames featuring different suspension designs, but it’s crucial to check the shock’s specifications to ensure it matches your frame’s kinematics.
• Weight Capacity: Choose the appropriate spring rate based on your body weight and riding style for optimal performance.
