The Öhlins TTX22M Coil [paid link] Rear Shock is a high-performance shock absorber designed to provide superior ride quality, precision, and durability for serious road cyclists and mountain bikers alike. Its cutting-edge technology and outstanding design make it one of the top choices for riders who demand the best in suspension. This guide will cover the key reasons to choose the TTX22M Coil [paid link], highlighting its installation, adjustment, maintenance, and performance optimization features.

Overview of the TTX22M Coil Rear Shock

The Öhlins TTX22M Coil Rear Shock is built to deliver unparalleled comfort, control, and responsiveness for your bike. It features Öhlins’ Twin Tube technology, providing excellent damping performance across a wide range of terrain and conditions. This shock is designed for riders who demand high performance, whether they are tackling rough trails or engaging in long-distance rides.

The shock uses a coil spring, which offers a linear spring rate, making it highly effective for absorbing large impacts and providing consistent performance over time. Its adjustable features allow cyclists to fine-tune the shock to match their riding style and terrain preferences.

Installation of the TTX22M Coil Rear Shock

Installing the TTX22M Coil Rear Shock requires a certain level of technical knowledge and the correct tools. Follow these steps to install the shock properly:

Tools Required:

  • 5mm and 6mm hex wrenches
  • Torque wrench [paid link]
  • T25 Torx driver
  • 17mm spanner (for coil spring removal)
  • Lubricant
  • Bicycle stand

Installation Steps:

  1. Preparation: Place the bike securely on a bike stand [paid link]. Ensure the bike is stable and the rear wheel is off the ground.
  2. Remove the Existing Shock: Use the 5mm hex wrench to unscrew the bolts securing the existing rear shock to the frame. Be cautious while removing the shock to avoid damaging any surrounding components.
  3. Install the New TTX22M Coil Shock: Position the TTX22M shock in place and insert the bolts through the shock’s mounting holes. Tighten the bolts securely using the appropriate hex wrenches.
  4. Torque the Bolts: Using a torque wrench [paid link], tighten the bolts to the manufacturer’s specified torque settings, ensuring the shock is securely mounted.
  5. Check for Proper Alignment: Ensure that the shock is aligned properly and that no parts are obstructed by surrounding components.
  6. Test Ride: After installation, perform a test ride to ensure the shock is functioning as expected. Pay attention to any unusual noises or issues with the suspension.

Adjustment and Customization for Better Performance

The TTX22M Coil Rear Shock is equipped with several adjustability features that allow riders to fine-tune the shock for optimal performance. These include:

Rebound Adjustment

Rebound adjustment controls how quickly the shock returns after compressing. This setting is crucial for managing the shock’s behavior over rough terrain.

  • Turn the rebound knob clockwise to slow down the rebound for smoother, more controlled damping on rough trails.
  • Turn the knob counterclockwise to speed up the rebound for a more responsive feel.

Compression Damping

Compression damping affects how the shock absorbs impacts and helps maintain ride stability. The TTX22M features separate high- and low-speed compression adjustments.

  • High-speed compression: Controls damping for larger, more forceful impacts (e.g., hitting a rock or a big bump).
  • Low-speed compression: Controls damping for smaller, more gradual bumps (e.g., rough pavement or small obstacles).

Coil Spring Tuning

The TTX22M Coil shock uses a coil spring for a linear spring rate, providing consistent performance. You can adjust the coil spring to suit your weight and riding style:

  • Spring Rate: Choose a spring rate that matches your weight and riding style. A heavier rider or more aggressive rider might require a stiffer spring.
  • Preload Adjustment: Adjust the preload to fine-tune the sag and ride height. Use a 17mm spanner to turn the preload collar to the desired position.

Maintenance of the TTX22M Coil Rear Shock

To ensure the longevity and optimal performance of the TTX22M Coil Rear Shock, regular maintenance is essential. Follow these steps for proper care:

  1. Clean the Shock Regularly: After each ride, clean the shock to remove dirt, mud, and debris. Use a damp cloth to wipe down the shock body and prevent the buildup of grime in the damper seals.
  2. Check for Leaks: Inspect the shock for any signs of oil or air leaks. Leaks can significantly affect the performance of the shock, so if any are detected, servicing may be required.
  3. Lubricate the Shock: Apply a small amount of lubricant to the shock’s moving parts to ensure smooth operation and prevent wear. Avoid over-lubricating as this can attract more dirt.
  4. Inspect the Coil Spring: Check the coil spring for any signs of damage, such as bends or cracks. If the spring is damaged, it must be replaced for safe operation.
  5. Service the Shock Periodically: Öhlins recommends servicing the shock every 100 hours of riding or once a year, whichever comes first. During the service, the shock will be disassembled, cleaned, and refilled with oil for optimal performance.

Troubleshooting Common Issues

While the TTX22M Coil Rear Shock is designed for durability and high performance, riders may encounter occasional issues. Below are some common problems and solutions:

1. Excessive Rebound or Sluggish Response

  • Cause: The rebound setting may be too fast or too slow.
  • Solution: Adjust the rebound knob to the desired speed. Turn it clockwise for slower rebound or counterclockwise for faster rebound.

2. Shock Not Compressing Properly

  • Cause: The coil spring may be too stiff for the rider’s weight or the shock may need maintenance.
  • Solution: Check the coil spring rate and adjust preload. If the problem persists, inspect the shock for any leaks or internal issues that may require servicing.

3. Noise or Creaking Sounds

  • Cause: Noise could be caused by dirt or debris on the shock, or loose mounting bolts.
  • Solution: Clean the shock thoroughly and tighten the mounting bolts to the correct torque settings.

Comparison with Other Rear Shocks

The TTX22M Coil Rear Shock stands out in comparison to other rear shocks due to its advanced technology, reliability, and fine-tuning options. For example, when compared to air shocks, the TTX22M’s coil spring offers more consistent and predictable performance, especially on rough terrain. Air shocks, while lighter, may not provide the same level of smoothness or durability, particularly for aggressive riders or those who frequently ride through rough, technical trails.

When compared to other coil shocks, the TTX22M distinguishes itself with Öhlins’ proprietary Twin Tube technology, providing better heat dissipation and enhanced damping performance. This feature gives it a noticeable advantage in both performance and reliability, particularly for long-duration rides.

Compatibility with Other Drivetrain Components

The TTX22M Coil Rear Shock is designed to work seamlessly with most modern bike frames, particularly those with suspension linkage systems that are compatible with coil shock designs. The shock is compatible with both standard and custom-built suspension systems. However, it is important to check for proper rear triangle geometry to ensure compatibility with your frame.

For optimal performance, the TTX22M Coil shock works best when paired with high-end drivetrains and suspension components, such as those offered by brands like SRAM and Shimano. When integrating the shock into a complete system, ensure that the components’ specifications align to avoid any compatibility issues.
