• 8mm Allen wrench [paid link]
• 10mm wrench (for mounting bolts)
• 6mm Allen wrench [paid link]
• Suspension grease
• Shock pump

Installation Steps:

1. Prepare the Bike Frame: Clean the area where the shock will be mounted. Ensure that the mounting points on the frame are free of dirt and debris to avoid damage to the shock’s bushings or seals.
2. Grease the Shock Mounting Points: Apply a thin layer of suspension grease to the shock’s mounting hardware and the frame’s contact points to prevent seizing and squeaking.
3. Mount the Shock: Position the TTX22M Coil Rear Shock into the frame’s mounting points. Align the shock eyelets with the mounting hardware.
4. Secure the Mounting Bolts: Using the appropriate wrench, tighten the mounting bolts to the manufacturer’s recommended torque specification. Ensure the bolts are tight but not overtightened, as this could damage the frame or shock.
5. Check the Coil and Spring Rate: Ensure the coil is installed correctly, with the correct spring rate for your rider weight and riding style. This step is crucial for maintaining optimal suspension performance.
6. Install the Shock Pump: Attach the shock pump to the air valve on the shock. Set the recommended pressure based on your rider weight and adjust the air pressure to fine-tune the compression and rebound settings.
7. Test the Suspension: Once installed, perform a visual check for any misalignment or loose bolts. Compress the suspension a few times to ensure smooth operation and that the shock is securely mounted.

Adjustment of the TTX22M Coil Rear Shock

The Öhlins TTX22M Coil Rear Shock is designed to offer fine-tuned adjustments for a variety of riding conditions. Proper adjustment allows you to tailor the shock to your riding preferences, ensuring a more comfortable and controlled ride.

Compression Adjustment:

The compression damping controls how the shock absorbs impacts from rough terrain. Adjusting this setting affects how the rear suspension behaves under compression during descents or while hitting obstacles.

• Low-Speed Compression: Adjust the low-speed compression to control how the shock behaves during slow, technical climbs and while pedaling. Turning the dial clockwise increases compression, making the shock firmer and less prone to bottoming out.
• High-Speed Compression: This dial adjusts how the shock reacts to large impacts or high-speed hits. Increase high-speed compression if you experience bottoming out on aggressive descents or rough trails.

Rebound Adjustment:

Rebound damping controls how quickly the shock returns to its original position after being compressed. Adjusting the rebound can affect the handling and control of the bike, especially on descents.

• Turn the rebound dial clockwise to slow the rebound and counterclockwise to speed it up. A slower rebound may offer better control over rough terrain, while a faster rebound can improve efficiency on smoother trails.

Spring Rate Adjustment:

Choosing the right coil spring rate is critical for optimal suspension performance. The TTX22M comes with a range of springs designed to match different rider weights.

• To change the spring, remove the shock from the frame and replace the existing coil with a new one that corresponds to your weight and riding style. The spring rate directly influences how the shock performs, so it’s essential to select the appropriate one.

Maintenance of the TTX22M Coil Rear Shock

Regular maintenance of the TTX22M Coil Rear Shock ensures its longevity and consistent performance. The shock is designed to be low maintenance but requires periodic inspection and service to keep it functioning at its best.

Cleaning the Shock:

1. Wipe Down the Shock: After each ride, wipe the shock with a clean cloth to remove dirt, debris, and moisture. Be sure to clean the shock body and the mounting hardware.
2. Inspect for Leaks: Check the shock’s seals for any signs of oil leakage. If you notice leakage, it’s time to have the shock serviced by an authorized Öhlins technician.

Servicing the Shock:

• Check the Eyelets and Bushings: Regularly inspect the shock’s eyelets and bushings for wear. If the bushings are loose or worn out, replace them to avoid damaging the shock or the frame.
• Re-grease Mounting Hardware: Each time you remove and reinstall the shock, make sure to reapply a thin layer of grease to the mounting hardware to prevent corrosion and ensure smooth operation.

Spring Maintenance:

• Inspect the Coil: Periodically check the coil for signs of wear or fatigue. If the coil appears damaged or worn, replace it immediately to maintain safe and optimal performance.

Professional Servicing:

Every 100-150 hours of riding, it’s recommended to have the shock fully serviced by a professional. During this service, the shock will be disassembled, cleaned, and re-oiled to restore its performance.

Troubleshooting Common Issues

While the TTX22M Coil Rear Shock is known for its durability, riders may occasionally encounter issues. Here are some common problems and their solutions:

Bottoming Out:

• Cause: Insufficient compression damping or incorrect spring rate.
• Solution: Increase the compression damping or switch to a stiffer coil spring that matches your weight and riding style.

Unusual Noises:

• Cause: Dry or worn bushings.
• Solution: Inspect the bushings for wear and lubricate them if necessary. If the noise persists, replace the bushings.

Poor Rebound Performance:

• Cause: Rebound damping set incorrectly or low oil levels.
• Solution: Adjust the rebound settings to your preference. If the problem persists, it may indicate the need for a full service.

Customization and Performance Optimization

The Öhlins TTX22M Coil Rear Shock is designed with a high degree of customization to allow riders to optimize performance for their specific needs. The following customizations can significantly enhance your riding experience:

Fine-Tuning the Suspension for Different Terrains:

• For Cross-Country Riding: Use a softer compression setting and moderate rebound to improve comfort and efficiency.
• For Enduro and Downhill: Set the compression damping firmer to handle high-speed impacts and increase rebound damping to maintain control on fast descents.

Tailoring the Suspension for Rider Weight:

• If you are a heavier rider, opt for a stiffer spring rate to prevent bottoming out. Conversely, lighter riders may benefit from a softer spring for better responsiveness.

Compatibility with Other Drivetrain Components

The TTX22M Coil Rear Shock is compatible with a wide range of mountain bike frames and drivetrains. However, it’s important to ensure that your bike’s rear triangle can accommodate the shock’s dimensions and travel range. Additionally, when selecting the shock’s spring rate, consider the overall weight distribution of your bike, including your weight and the weight of any additional components.

Conclusion

The Öhlins TTX22M Coil Rear Shock is a highly regarded suspension option for riders seeking exceptional performance, durability, and adjustability. Its advanced features, including the ability to fine-tune compression, rebound, and spring rate, make it ideal for various riding conditions. Regular maintenance and the right adjustments will ensure that your shock continues to perform optimally, whether you are tackling technical trails or taking on fast descents. By understanding the shock’s setup, customization options, and troubleshooting techniques, riders can enjoy a smoother and more controlled ride.
