The Öhlins TTX1Air rear shock is a high-performance component designed to provide exceptional suspension for road bikes. Proper maintenance of this shock is critical to maintaining its performance, safety, and longevity. This guide will walk you through the essential tasks for installation, adjustment, and troubleshooting, as well as tips for optimizing its performance and ensuring compatibility with other components.

Installation of the TTX1Air Rear Shock

Step 1: Preparation

Before installing the TTX1Air rear shock, ensure you have the right tools and workspace. You should also check that your bike’s frame is compatible with the shock’s mounting requirements.

Step 2: Removing the Old Shock

  • Use a 5mm Allen wrench [paid link] to remove the bolts securing the old shock to the frame.
  • Carefully detach the shock from the bike and inspect the mounting points for any wear or damage.

Step 3: Mounting the TTX1Air

  • Slide the TTX1Air rear shock into the mounting brackets.
  • Secure the shock in place using the provided hardware. Make sure to torque the bolts to the manufacturer’s specifications to avoid over-tightening or under-tightening.
  • Double-check the alignment to ensure the shock sits evenly within the mounting points.

Step 4: Air Pressure Setup

  • Using a shock pump, add air to the TTX1Air’s air chamber. Refer to the recommended air pressure settings based on your weight and riding style.
  • Make small adjustments as necessary, but avoid over-inflating.

Step 5: Final Checks

Once the shock is securely mounted, check for any interference with the frame or other components. Test the suspension by gently compressing and releasing it to ensure it moves smoothly.

Adjustment and Fine-Tuning of the TTX1Air

Rebound Adjustment

  • The TTX1Air features a rebound adjuster on the shock body. Turn the knob clockwise to slow down the rebound and counterclockwise to speed it up.
  • Adjust the rebound to suit your riding conditions. A slower rebound is beneficial for aggressive, technical trails, while a faster rebound is ideal for smoother terrain.

Compression Adjustment

  • The shock’s compression settings are typically adjusted through a dial or valve on the shock. The TTX1Air allows you to fine-tune low-speed and high-speed compression.
  • Low-speed compression should be adjusted for general damping to prevent bottoming out on larger hits. High-speed compression affects the shock’s response to more abrupt, fast impacts.
  • Begin with the manufacturer’s recommended settings and make small adjustments based on your riding style and terrain.

Air Volume Adjustment

  • The TTX1Air allows for adjustments in the air volume to fine-tune the shock’s response. Increasing the air volume can make the shock more linear, while decreasing it will create a more progressive feel.
  • If you’re experiencing bottoming out on large impacts, increase the air volume to make the shock firmer.

Troubleshooting Common Setup Issues

Loss of Air Pressure

  • If you notice a decrease in performance or feel a softening in the shock, check the air pressure.
  • Over time, the air chamber may lose pressure. Use a shock pump to re-inflate the shock to the appropriate settings.
  • If the pressure loss is significant, inspect the shock for leaks, especially around the air valve and seals.

Shock Not Rebounding Correctly

  • If the shock rebounds too quickly or too slowly, adjust the rebound dial.
  • If adjustments do not solve the issue, there may be an internal problem, such as low oil levels or damaged internal seals. In this case, it’s recommended to have the shock serviced by a professional.

Bottoming Out

  • Bottoming out can occur if the air pressure is too low or the compression settings are too soft.
  • Check the air pressure and adjust the compression settings for more support. Adding volume spacers can also help to reduce the likelihood of bottoming out.

Customization and Optimization for Better Performance

Optimizing Air Pressure

  • Set the air pressure based on your weight and riding style. Lighter riders may prefer a softer shock, while heavier riders may need a firmer setting to prevent bottoming out.
  • Take into account your typical riding conditions. For rough, technical terrain, a firmer shock with higher air pressure will provide better control and prevent excessive shock compression.

Tuning Compression for Terrain

  • Fine-tune the compression settings based on the type of terrain you’re riding on. For technical and bumpy trails, lower the compression settings to absorb more shocks. For smoother roads, a firmer setting may provide better efficiency.

Upgrade Internal Components

  • For riders seeking a higher level of performance, consider upgrading the internal components of the shock, such as the damper cartridge. These upgrades can offer more precise damping control and enhance overall suspension performance.

Comparison with Other Rear Shocks

TTX1Air vs. TTX2Air

While the TTX1Air offers high performance for road bikes, it is a simpler, lighter shock compared to the TTX2Air, which offers more advanced features, such as separate high- and low-speed compression adjustments. The TTX2Air is typically used for more demanding trails and heavier riders who require enhanced performance in extreme conditions.

TTX1Air vs. Fox Float X2

Compared to the Fox Float X2, the TTX1Air provides a slightly more responsive and consistent feel due to its twin-tube design, which better isolates the air chamber from the damper. However, the Fox Float X2 offers a broader range of adjustability, including the ability to adjust both low- and high-speed rebound separately. The TTX1Air, while slightly less adjustable, remains a great option for riders looking for a reliable, high-quality rear shock with a simpler design.

Compatibility with Other Drivetrain Components

Integration with Other Öhlins Components

The TTX1Air rear shock is designed to work seamlessly with other Öhlins suspension components, including their front forks and hydraulic dampers. This ensures a consistent feel across the bike and allows for more cohesive adjustments.

Compatibility with Non-Öhlins Components

While the TTX1Air is compatible with most modern road bike drivetrains, ensure that your bike’s rear triangle can accommodate the shock’s dimensions and mounting hardware. If you’re unsure, it is always best to consult the bike’s manufacturer for compatibility information. Additionally, the shock’s adjustments for compression and rebound should be set in a way that complements the performance of your bike’s fork and other suspension components.

Conclusion

Maintaining and adjusting the Öhlins TTX1Air rear shock is key to ensuring a smooth and responsive ride. By following the installation and maintenance steps outlined in this guide, as well as troubleshooting common issues and fine-tuning the shock’s performance, you can optimize your bike’s suspension system for various riding conditions. Whether you’re tackling challenging terrain or enjoying a leisurely ride, the TTX1Air provides the durability and precision needed for superior performance.
