The TTX2Air rear shock by Öhlins is a high-performance suspension component known for its superior damping, reliability, and adjustability. As with any top-tier component, proper maintenance and care are essential to maximize its lifespan and maintain peak performance. In this guide, we will walk you through essential maintenance steps, troubleshooting tips, and optimization techniques to ensure your TTX2Air performs at its best for years to come.
Tools Required
- 8mm hex wrench
- Torque wrench [paid link] (up to 20Nm)
- 5mm hex wrench
- Shock pump
- Suspension fluid (Öhlins recommended)
- Grease (suspension specific)
- Soft cloths for cleaning
- Small brush (e.g., toothbrush)
- Rags for wiping down components
- Air compressor (optional)
- TTX2Air service kit (for major overhauls)
Installation of the TTX2Air Rear Shock
The TTX2Air rear shock should be installed with care to avoid damaging sensitive internal components. Follow these steps to ensure a proper fit:
- Prepare the Frame Mounting Area:
- Clean the frame shock mount thoroughly, removing any dirt or debris. A clean contact area ensures a solid and secure fit.
- Apply Grease:
- Apply a light coat of grease to the shock eyelet bushings. This will facilitate smooth movement and prevent squeaking.
- Insert the Shock:
- Carefully insert the TTX2Air rear shock into the frame’s shock mount. Ensure the shock is properly aligned with the mounting holes.
- Secure the Mounting Bolts:
- Use a 5mm hex wrench to tighten the mounting bolts. Make sure the bolts are tightened to the manufacturer’s recommended torque specification, usually around 20Nm. Over-tightening can damage the shock.
- Check for Proper Movement:
- After installation, check the shock’s movement by compressing and rebounding it gently. It should move freely without any binding or resistance.
Adjustment and Fine-Tuning
One of the standout features of the TTX2Air rear shock is its adjustable settings. Fine-tuning these adjustments allows riders to personalize the shock’s performance. Follow these steps to adjust your TTX2Air for optimal ride quality:
- Rebound Adjustment:
- Use the rebound dial at the bottom of the shock to control the speed at which the shock returns after compression. If the rebound is too fast, the shock will “bounce” and destabilize the bike. Conversely, if it’s too slow, the bike will feel sluggish.
- Compression Adjustment:
- Adjust the compression setting to control how much the shock resists compression during impacts. For softer terrain or less aggressive riding, a lower compression setting is ideal. For technical trails or aggressive riding, a firmer setting is better to reduce bottoming out.
- Air Pressure:
- The TTX2Air features an air spring. Use a shock pump to adjust the air pressure based on your body weight and riding style. Higher air pressure will result in a firmer ride, while lower pressure provides more plushness.
- Adjust for Riding Conditions:
- Adjust the compression and rebound settings depending on the terrain and weather conditions. Softer settings work better in rough, technical terrain, while firmer settings are suitable for smoother trails or when carrying heavier loads.
Maintenance Tips for Prolonging the Life of Your TTX2Air
Regular maintenance is crucial for keeping your TTX2Air rear shock in top condition. Here are some simple steps you can follow to extend its lifespan:
- Regular Cleaning:
- Clean your shock after every ride. Use a soft cloth to wipe down the shock body, especially around the seals and the air spring. Dirt and grime can cause wear on the seals, leading to leaks.
- Inspect Seals:
- Check the seals regularly for any signs of wear or damage. If you notice any damage, replace the seals immediately to prevent air leakage or fluid loss.
- Check Air Pressure:
- Regularly check the air pressure, especially before and after long rides. Fluctuations in pressure can affect performance and lead to air spring damage.
- Lubricate the Shock:
- Periodically apply a light coating of suspension-specific grease to the shock eyelets to prevent corrosion and improve smoothness during compression.
- Monitor for Leaks:
- Keep an eye out for oil or air leaks around the shock seals and air valve. Any leaks indicate a need for immediate maintenance to avoid damaging the shock.
Troubleshooting Common TTX2Air Issues
While the TTX2Air is a durable and reliable shock, you may occasionally encounter some common issues. Here’s how to troubleshoot and fix them:
- Shock Not Rebounding Properly:
- If the shock is not rebounding, check the rebound adjustment dial. If it is correctly set and still not working, the rebound damper may be malfunctioning and require a professional service.
- Air Spring Not Holding Pressure:
- If you notice that the shock is losing air, inspect the air valve for any damage or debris. If the valve is intact, the issue may be with the air seal, which may need to be replaced.
- Excessive Bottoming Out:
- If the shock bottoms out frequently, increase the air pressure or adjust the compression damping. If the issue persists, inspect the shock for oil leaks or internal damage that may require professional service.
- Noise During Compression:
- Any noise during compression could be a sign of dirt or debris inside the shock. Clean the shock thoroughly, paying close attention to the seals and moving parts. If the noise persists, it may indicate internal wear, and servicing is recommended.
Customization and Optimization for Better Performance
To get the most out of your TTX2Air rear shock, consider customizing it for your specific riding style and preferences. Here are some tips for optimization:
- Tuning for Weight and Riding Style:
- Adjust the air pressure based on your body weight and the type of riding you plan to do. Lighter riders may require less air pressure, while heavier riders may need more. Similarly, adjust the rebound and compression settings based on the terrain you frequent.
- Custom Seals and Oil:
- If you’re seeking a more specific performance characteristic (such as smoother compression or more progressive rebound), experimenting with different suspension oils and custom seals can improve the ride quality.
- Upgrading Internal Components:
- For more advanced riders, upgrading internal components, such as the piston or damping cartridge, can offer enhanced performance. Consult with a professional mechanic or Öhlins dealer for advice on suitable upgrades for the TTX2Air.
Compatibility with Other Drivetrain Components
The TTX2Air rear shock is compatible with a variety of mountain bike setups, but compatibility with other drivetrain components should be considered when upgrading or installing. Ensure that the shock’s mounting size and stroke length align with your frame specifications. Additionally, make sure your bike’s rear triangle has the appropriate clearance for the shock to perform optimally without interference from other components.
Conclusion
The Öhlins TTX2Air rear shock is an excellent choice for cyclists who demand the highest level of performance from their suspension. By following the installation, maintenance, and adjustment guidelines outlined in this article, you can ensure that your shock provides smooth, reliable performance for many rides to come. Regular cleaning, inspections, and minor adjustments are essential for prolonging its life and preventing costly repairs. Whether you’re tuning it for your personal riding style or troubleshooting an issue, the TTX2Air can continue to deliver top-tier performance with the right care and attention.
