Installation of the Öhlins STX22 Coil Rear Shock

The installation of the STX22 Coil rear shock is a straightforward process, but it requires attention to detail to ensure the shock is mounted correctly for optimal performance. Follow these steps to install the shock on your bike:

1. Preparation:
   • Ensure your bike is clean and in a stable position.
   • Remove the rear wheel if necessary to gain better access to the rear shock area.
2. Remove the Existing Shock:
   • Use a wrench to remove the bolts securing the existing shock to the frame and linkages. Keep these bolts, as you will need them for the new shock.
3. Install the Öhlins STX22 Coil Rear Shock:
   • Carefully place the STX22 Coil shock in the shock mount and align the mounting holes.
   • Secure the shock with the bolts, tightening them to the manufacturer’s recommended torque specifications.
4. Reinstall the Rear Wheel:
   • If the rear wheel was removed for access, now is the time to reinstall it.
5. Final Check:
   • Double-check all bolts for tightness and ensure the shock is securely mounted.
   • Inspect the suspension linkage to ensure there is no interference with other components.

By following these steps, you can successfully install the Öhlins STX22 Coil rear shock and begin enjoying its enhanced ride quality.

Adjusting the Öhlins STX22 Coil Rear Shock

The STX22 Coil rear shock is built for easy adjustability, allowing you to fine-tune your suspension for a variety of riding styles and terrain. Key adjustments include:

Spring Preload Adjustment

Spring preload allows you to adjust the ride stiffness by compressing the coil spring. This setting is critical for achieving the correct sag, which is the amount the shock compresses under your body weight.

• To adjust preload: Use the provided tool to turn the preload collar clockwise to increase preload (stiffer ride) or counterclockwise to decrease preload (softer ride).
• Recommended sag: For most riders, 25-30% sag is ideal. This means the shock should compress 25-30% of its total travel under the rider’s weight.

Rebound Adjustment

Rebound damping controls how quickly the shock returns to its original position after compression. Proper rebound damping helps maintain control over rough terrain and ensures the shock does not rebound too quickly, causing instability.

• To adjust rebound: Turn the rebound adjuster knob located at the base of the shock. Clockwise will slow the rebound, while counterclockwise will speed it up.
• Optimal setting: Aim for a rebound setting that allows the shock to return smoothly without bouncing back too quickly or too slowly.

Compression Damping

Compression damping controls how the shock reacts to bumps and impacts. The STX22 Coil shock offers both low-speed and high-speed compression adjustments.

• Low-speed compression: This adjusts the shock’s response to slower impacts such as pedal strikes or light terrain.
• High-speed compression: This adjusts the shock’s response to faster, more aggressive impacts like drops or rough trails.

By adjusting both rebound and compression, you can significantly enhance the shock’s performance on different terrains, providing you with better control and comfort.

Maintaining the STX22 Coil Rear Shock

Regular maintenance of the STX22 Coil rear shock is essential for preserving its performance and longevity. Öhlins recommends the following maintenance practices:

1. Cleaning: After each ride, wipe down the shock with a clean, dry cloth to remove dirt and debris. Make sure to clean the shock’s shaft and any moving parts.
2. Lubrication: Periodically lubricate the shock’s mounting bolts and seals with appropriate suspension fluid or grease to prevent wear.
3. Spring Inspection: Inspect the coil spring for signs of damage or wear. Replace the spring if you notice any cracks or deformation.
4. Oil Change: It is recommended to perform a full oil change every 50-100 hours of riding. This will maintain optimal damping performance.

By keeping your STX22 Coil rear shock clean and well-maintained, you ensure that it will continue to deliver top-notch performance for years to come.

Troubleshooting Common STX22 Coil Rear Shock Issues

While the STX22 Coil rear shock is known for its reliability, you may encounter a few common issues that can affect performance. Here are some troubleshooting tips:

Issue 1: Insufficient Shock Travel

If you notice that the shock isn’t compressing as much as it should, the most likely cause is an incorrect spring preload setting.

• Solution: Recheck the preload setting and adjust it to achieve the proper sag (25-30%).

Issue 2: Bouncing After Compression

If the shock rebounds too quickly or bounces excessively, this usually indicates too little rebound damping.

• Solution: Increase the rebound damping by turning the rebound adjuster knob clockwise to slow the shock’s return.

Issue 3: Lack of Control on Rough Terrain

If you’re not feeling enough control on aggressive terrain, you may need to adjust the compression settings.

• Solution: Increase the low-speed and/or high-speed compression damping depending on the terrain you are riding.

Customizing the STX22 Coil Rear Shock for Optimal Performance

Customization of the STX22 Coil rear shock can enhance its performance, ensuring it’s tuned to your specific riding style and conditions. Consider the following customizations:

1. Spring Rate: The stock spring may not be ideal for all riders. If you are experiencing bottoming out or not enough support, you can swap to a stiffer or softer coil spring depending on your weight and riding style.
2. Shock Mounts: Depending on your bike’s frame, you may need specific shock mounts or bushings to ensure proper fit and alignment.
3. Volume Spacers: Some riders use volume spacers to adjust the shock’s compression curve, making the shock feel more progressive for technical rides or aggressive riding.

By fine-tuning these aspects, you can tailor the STX22 Coil rear shock to your exact preferences.

Compatibility with Other Drivetrain Components

The STX22 Coil rear shock is designed to work seamlessly with a wide range of drivetrain components. However, compatibility with your bike’s frame and rear triangle is critical for proper performance. Ensure that the following components are compatible with the STX22 Coil:

• Rear Shock Mounting Points: Check that your bike’s shock mount spacing matches the STX22’s mounting system.
• Suspension Linkage: The shock should be compatible with the suspension design of your bike, whether it’s a single-pivot or multi-link system.

Most modern mountain bikes and enduro bikes are compatible with the STX22 Coil, but it’s important to check the manufacturer’s specifications for your specific frame.
