Installation of the Öhlins TTX22M Coil Rear Shock

Installing the TTX22M Coil Rear Shock requires careful attention to detail to ensure it functions at its best. Follow these steps to properly install the shock:

1. Remove the Existing Shock:
   • Ensure that the bike is stable and secured, either on a bike stand [paid link] or upside down.
   • Use a 5mm or 6mm Allen wrench [paid link] to remove the bolts securing the old shock in place. Keep the bolts, as they may be reused for the new shock.
   • Carefully slide the old shock out of its mounting brackets.
2. Prepare the TTX22M Coil Rear Shock:
   • Unbox the Öhlins TTX22M Coil Rear Shock and inspect it for any damage during shipping.
   • Ensure that the coil spring is correctly preloaded and is securely attached.
3. Install the New Shock:
   • Align the mounting eyelets of the shock with the corresponding holes on the frame and the rear triangle.
   • Insert the shock into position, ensuring that it sits securely in the mounting points.
   • Use the provided bolts to attach the shock to the frame. Tighten them to the manufacturer’s recommended torque specification (typically between 18-25 Nm).
4. Check for Clearance:
   • Verify that the shock does not interfere with any other components when the suspension is compressed. Make adjustments as needed to avoid contact.
5. Test the Suspension:
   • Once installed, compress the shock by pressing down on the rear of the bike. This will help settle the shock into its mounting position.
   • Check the shock’s performance by cycling through different travel settings.

Adjusting the Öhlins TTX22M Coil Rear Shock

The Öhlins TTX22M offers a wide range of adjustments to tailor the shock’s performance to your riding style and terrain. These include adjustments for rebound, compression, and spring preload. Here’s how to adjust each one:

Rebound Adjustment

The rebound setting controls the speed at which the shock returns to its original position after compression. If the rebound is too fast, the bike may feel twitchy, while a slow rebound can make the suspension feel sluggish.

• Locate the Rebound Knob: The rebound adjuster is typically found at the bottom of the shock.
• Adjusting Rebound: Turn the knob clockwise to slow the rebound and counterclockwise to increase the rebound speed. Start with a moderate setting and fine-tune based on your preference.
• Test and Fine-Tune: After each adjustment, test ride the bike to feel the difference in rebound. Adjust further as needed to achieve a smooth, controlled return without excessive bouncing.

Compression Adjustment

The compression setting affects how much the shock resists compression during impacts or heavy loads.

• Locate the Compression Knob: The compression knob is typically found at the top of the shock.
• Adjusting Compression: Turn the knob clockwise to increase compression resistance and counterclockwise to soften the compression. The ideal setting depends on your weight, riding style, and terrain. Start with a balanced setting and adjust based on your needs.
• Test and Fine-Tune: After each change, ride the bike and evaluate the shock’s performance. If you find the shock bottoming out too often, increase the compression. If you need more sensitivity to smaller bumps, decrease the compression.

Spring Preload Adjustment

The preload setting determines the amount of tension placed on the spring, affecting the initial ride feel.

• Locate the Preload Collar: The preload collar is located around the shock’s coil spring.
• Adjusting Preload: Rotate the collar to increase or decrease the preload. Tightening the collar increases the preload, making the shock stiffer, while loosening it reduces the preload for a softer ride.
• Test and Fine-Tune: Adjust the preload based on your rider weight and the type of terrain. Start with a neutral preload and adjust as necessary for better balance and comfort.

Maintenance of the Öhlins TTX22M Coil Rear Shock

Proper maintenance is crucial for ensuring the longevity and optimal performance of your TTX22M Coil Rear Shock. Follow these steps to maintain your shock:

Regular Cleaning

• Clean the shock after every ride to prevent dirt and grime from accumulating.
• Use a soft brush and mild soap with water to clean the body of the shock.
• Avoid using high-pressure water or solvents that can damage seals.

Lubrication

• Apply a light coat of silicone-based lubricant to the shock’s moving parts, such as the shaft and the spring. This will help reduce friction and prevent wear.
• Make sure to wipe off any excess lubricant to prevent attracting dirt.

Inspecting Seals and Bushings

• Check the shock seals regularly for any signs of wear or leakage. If you notice any oil leakage, it may be time to replace the seals.
• Inspect the shock’s bushings for smooth movement and replace them if they show signs of wear.

Spring Maintenance

• If you are riding in harsh conditions, consider checking the spring’s condition periodically. Look for any signs of wear or sagging and replace the spring if necessary.

Troubleshooting Common Issues

No Rebound or Slow Rebound

• Cause: This could be due to a stuck rebound valve or low oil levels inside the shock.
• Solution: Check the rebound adjuster and ensure it is functioning properly. If the problem persists, inspect the shock’s internals or take it to a certified technician for servicing.

Bottoming Out

• Cause: If the shock is bottoming out frequently, it may be too soft for your weight or the terrain.
• Solution: Increase the compression setting or adjust the spring preload to provide more resistance. You may also need to switch to a stiffer spring.

No Compression or Stiff Compression

• Cause: This could be caused by a damaged compression damper or improper settings.
• Solution: Check the compression adjustment knob for any issues. If the shock feels overly stiff or unresponsive, the internals may need servicing.

Customization and Optimization for Better Performance

The TTX22M Coil Rear Shock offers numerous ways to optimize your bike’s performance. Consider these tips for customization:

Fine-Tune Suspension Based on Terrain

• For technical terrain, set the shock to be more responsive by reducing compression and increasing rebound speed for quick recovery after obstacles.
• On fast descents, increase the compression to provide more control and reduce the chance of bottoming out.
• For cross-country riding, adjust the shock for a balanced feel, ensuring both sensitivity and support.

Rider Weight Considerations

• Heavier riders may need a stiffer spring or more preload to prevent the shock from bottoming out.
• Lighter riders can opt for a softer setup for a more comfortable ride and better sensitivity to smaller bumps.

Riding Style Adaptation

• Aggressive riders or those who tackle rough trails may benefit from increased compression and slower rebound settings.
• Casual riders may prefer a softer setup with quicker rebound to maximize comfort over a variety of terrains.

Compatibility with Other Drivetrain Components

The TTX22M Coil Rear Shock is compatible with a wide range of modern mountain bike setups. However, there are a few considerations to ensure compatibility with your drivetrain:

• Shock Length: Ensure that the shock’s eye-to-eye length and stroke are suitable for your frame’s geometry.
• Mounting System: The TTX22M is designed to work with a standard mounting system, but some frames may require specific adapters.
• Linkage Design: The shock works well with most frame linkage designs, but it’s essential to verify that your bike’s suspension linkage supports the travel and shock length you are installing.

By keeping these factors in mind, you can integrate the TTX22M Coil Rear Shock into your bike’s existing setup without compatibility issues.
