Öhlins is renowned for producing some of the finest suspension components in the cycling world, and the TTX1Air rear shock is no exception. Designed for performance and durability, this rear shock is a favorite among professional and amateur riders who demand exceptional handling, comfort, and precision. This article provides a detailed guide on the TTX1Air, covering its installation, adjustment, maintenance, troubleshooting, and compatibility with other drivetrain components, helping you get the most out of your investment.
Overview of the TTX1Air Rear Shock
The TTX1Air is part of Öhlins’ TTX series, which is known for its unique twin-tube design. The shock uses a high-pressure air spring combined with a precision damper to provide superior performance in both climbing and descending conditions. Unlike traditional rear shocks, the TTX1Air integrates advanced technology to offer enhanced stability, responsiveness, and fine-tuned adjustments, making it a standout in the competitive cycling world.
Installation of the TTX1Air Rear Shock
Installing the TTX1Air rear shock requires careful attention to detail to ensure it functions correctly and provides the optimal performance. Follow these steps for a precise and safe installation:
- Prepare the Bike Frame
Ensure that the bike frame is clean and free of any debris, especially where the shock mounts. - Remove the Existing Shock
If you’re replacing an existing rear shock, start by removing it from the frame. Use appropriate tools to unbolt the shock from both ends, ensuring that you handle the frame carefully to avoid damaging it. - Install the TTX1Air Shock
- Align the TTX1Air shock with the mounting points on your bike frame.
- Insert the shock into the frame and tighten the bolts securely. Ensure that the shock is properly positioned in the mounts, avoiding any lateral movement.
- Adjust the Air Pressure
The TTX1Air requires a proper air pressure setting to function optimally. Use an accurate shock pump to set the air pressure according to your weight and riding style. Start with Öhlins’ recommended baseline and make adjustments based on testing. - Connect the Remote (If Applicable)
If you’re using a remote control for lockout or compression adjustment, install the remote lever to your handlebars and connect the hydraulic line or cable as per the manufacturer’s instructions. - Final Check
Before you finish the installation, ensure all bolts are tightened to the recommended torque specifications. Check that the shock moves smoothly and does not have any play.
Adjustment of the TTX1Air Rear Shock
To get the best performance from the TTX1Air, you’ll need to adjust the settings for your riding style, terrain, and personal preferences. The TTX1Air features multiple adjustment options, including compression and rebound damping, as well as air spring pressure. Here’s how to adjust each component:
Compression Damping
The TTX1Air features high and low-speed compression adjustments.
- High-Speed Compression: Controls the shock’s response to large impacts like drops and jumps. Start by setting the high-speed compression to a mid-range position and adjust based on how the shock reacts to bigger impacts.
- Low-Speed Compression: This setting fine-tunes the shock’s response to smaller impacts, like pedaling forces. For better pedaling efficiency, increase low-speed compression. If you want a plusher feel, decrease it.
Rebound Damping
Rebound damping controls how quickly the shock returns after compression.
- Start with the rebound adjustment set to mid-range.
- Adjust it slower if the rear end feels too bouncy or faster if the shock feels too sluggish after compression.
Air Spring Pressure
The air spring pressure is crucial for setting the sag and ride feel of the shock. The right pressure depends on your weight, riding style, and terrain.
- The ideal sag is usually between 25% and 30% of the shock’s total travel. Use an accurate shock pump to adjust the air pressure accordingly.
Maintenance of the TTX1Air Rear Shock
To ensure the longevity and optimal performance of the TTX1Air rear shock, regular maintenance is required. Here’s how to keep it in top condition:
Clean the Shock Regularly
After every ride, especially in wet or muddy conditions, clean the shock body using a mild detergent and water. Use a soft brush to remove dirt from the shock’s shafts, ensuring that seals remain intact.
Inspect Seals and Bushings
Check the seals around the shock for wear. Over time, these components can degrade and cause oil or air leaks. If you notice oil leakage or reduced performance, it may be time to replace the seals or bushings.
Service Interval
Öhlins recommends servicing the TTX1Air rear shock every 100-150 hours of riding, depending on conditions. Regular servicing will help maintain the internal components, ensuring that the shock operates smoothly for years.
Check Air Pressure
Periodically check the air pressure using a shock pump. Air pressure can change with temperature fluctuations or over time, so it’s important to keep it within the recommended range.
Troubleshooting Common Issues
If you’re experiencing issues with your TTX1Air, it’s important to diagnose and address them promptly to avoid damage. Here are common problems and solutions:
Shock Not Moving Smoothly
- Cause: The shock may have too much air pressure or insufficient lubrication.
- Solution: Adjust the air pressure to the recommended setting and ensure the shock is properly lubricated.
Bottoming Out Too Easily
- Cause: Low air pressure or incorrect compression settings.
- Solution: Increase air pressure or adjust compression settings to provide more support during impacts.
Excessive Bounce or Harsh Feel
- Cause: Incorrect rebound damping or too much low-speed compression.
- Solution: Slow down the rebound or reduce the low-speed compression to improve the shock’s response.
Customization and Optimization
The TTX1Air is highly customizable to suit different riding styles. Here are some ways you can fine-tune the shock for better performance:
- Adjust Compression for Terrain: On smoother terrain, reduce compression damping to get more compliance and comfort. On rougher trails, increase compression to provide better control.
- Play with Rebound Settings: For aggressive riders, faster rebound speeds may offer better control after big hits. For trail riders who value comfort, slower rebound can provide a smoother, more controlled feel.
Compatibility with Other Drivetrain Components
The TTX1Air rear shock is designed to work seamlessly with a variety of drivetrain components. However, it is important to ensure that your shock’s mounting style and travel length are compatible with your bike’s frame and other suspension components. Most modern mountain bike frames will support the TTX1Air, but always check the specifications before purchasing.
The shock’s air spring system and damping adjustments make it compatible with most high-performance drivetrains. However, if you’re running a high-end drivetrain with very specific chainline or suspension requirements, you may want to confirm compatibility with a local bike shop.
Conclusion
The Öhlins TTX1Air rear shock stands out due to its superior performance, adjustability, and reliability. Whether you’re tackling steep descents or cruising on rugged trails, this shock provides the precision and comfort needed for an exceptional ride. By understanding its installation, adjustment, maintenance, and troubleshooting, you can ensure that the TTX1Air remains a high-performance asset in your bike’s suspension system for many rides to come.
