Installation of the TTXAir 2.1 Rear Shock
Proper installation of the TTXAir 2.1 rear shock ensures that it performs optimally. Incorrect installation can result in poor performance or damage to the shock and other bike components.
Steps for Installing the TTXAir 2.1 Rear Shock:
- Position the Bike: Secure the bike on a work stand to ensure stability during the installation process.
- Remove the Existing Shock: If you’re replacing a shock, use the correct tools to remove the old shock. Carefully remove the bolts securing the shock to the frame.
- Install the TTXAir 2.1: Position the TTXAir 2.1 rear shock in place. Ensure the eyelets align correctly with the frame’s mounting points.
- Tighten the Bolts: Use a torque wrench [paid link] to tighten the mounting bolts. Be sure to adhere to the manufacturer’s torque specifications to avoid overtightening, which could damage the frame or shock.
- Check Alignment: Before tightening fully, double-check the alignment of the shock to ensure it is in the correct position.
- Set the Air Pressure: Use a shock pump to set the air pressure to the recommended level based on rider weight and preferred riding style.
Compatibility Check:
Ensure the TTXAir 2.1 is compatible with your bike frame and other suspension components. The shock’s stroke length, eyelet diameter, and shock mount style must align with your bike’s specifications.
Adjusting Your TTXAir 2.1 Rear Shock
The TTXAir 2.1 allows for a range of adjustments, including air pressure, rebound damping, and compression damping. These adjustments enable riders to customize the shock’s performance based on their specific needs.
1. Air Pressure Adjustment:
- Use a shock pump to adjust the air pressure in the shock. The recommended pressure is based on your weight and riding style. Adjust the pressure for optimal balance between comfort and control.
- Remember, the air pressure directly affects the shock’s overall feel, and slight adjustments can make a big difference in performance.
2. Rebound Damping:
- Rebound damping controls the shock’s return speed after compression. If the rebound is too fast, the shock will feel bouncy and unstable. If it’s too slow, the shock will feel sluggish and can result in a harsh ride.
- Adjust the rebound using the designated dial on the shock. Turn clockwise to slow the rebound and counterclockwise to increase it.
3. Compression Damping:
- Compression damping controls the shock’s resistance to compression forces. The TTXAir 2.1 offers a range of adjustments, from open (soft) to firm (stiff).
- Adjust the compression damping by turning the compression adjuster knob. For smoother trails, a softer setting is preferred, while a firmer setting is ideal for aggressive riding or rough terrain.
Routine Maintenance of the TTXAir 2.1 Rear Shock
Regular maintenance is essential to keep your TTXAir 2.1 rear shock functioning optimally over time. This includes checking air pressure, cleaning, lubricating, and inspecting seals and parts for wear.
Cleaning and Lubricating:
- Clean the shock regularly after rides, especially after wet or muddy conditions. Use a clean, damp rag to wipe down the shock body and remove dirt or debris. Avoid using harsh chemicals or solvents, as these can damage the shock.
- Apply suspension-specific grease to the shock’s eyelets and bushings to ensure smooth movement. Be careful not to over-lubricate, as excess grease can attract dirt.
Inspecting Seals:
- Inspect the shock’s seals regularly for wear. Signs of leaking oil or excessive friction may indicate that the seals need to be replaced.
- For heavy-duty maintenance, it’s recommended to remove the shock’s seal head and inspect or replace seals as necessary. Always use a seal driver tool to avoid damaging the seals during installation.
Troubleshooting Common Issues with the TTXAir 2.1
1. Shock Bottoming Out:
- If the shock bottoms out too easily, it could be due to low air pressure or inadequate compression damping. Check the air pressure and increase it if necessary. Adjust the compression damping to prevent excessive compression.
2. Harsh or Bouncy Ride:
- A harsh or bouncy ride could be the result of excessive rebound damping or incorrect air pressure. Try adjusting the rebound to a slower setting and adjust the air pressure to suit your weight and riding style.
3. Leaking Oil:
- If you notice oil leaking from the shock, this is often an indication of worn-out seals or a damaged shock body. Replace the seals or consider sending the shock in for a full service if the leak persists.
4. Excessive Noise or Sticking:
- Excessive noise or sticking can be caused by insufficient lubrication or dirt buildup in the shock’s moving parts. Clean and lubricate the shock thoroughly to resolve this issue.
Customizing the TTXAir 2.1 for Better Performance
To maximize the performance of your TTXAir 2.1, consider these customization tips:
- Adjust the Air Pressure for Optimal Sag: Ensuring the correct sag is crucial for maintaining balanced performance. Use the recommended sag settings, typically around 25-30% of the shock’s total stroke.
- Fine-tune Compression and Rebound: Experiment with different settings to match the shock to your riding style. For example, riders who prefer aggressive downhill riding may need more compression damping, while trail riders might opt for a softer setup.
- Upgrade to Higher-Quality Bushings: If you’re looking for increased smoothness, upgrading to high-quality bushings can reduce friction and improve the shock’s responsiveness.
Comparison with Similar Models
The Öhlins TTXAir 2.1 is a premium rear shock, but it’s always worth considering other models when making a purchase. Compared to other high-end shocks like the Fox Float X2 or RockShox Super Deluxe, the TTXAir 2.1 stands out with its advanced damping system and exceptional adjustability. It is particularly favored by riders looking for a shock that offers both plush performance and excellent control.
While the Fox Float X2 provides similar adjustability, the TTXAir 2.1’s unique twin-tube design delivers more consistent performance across various conditions. On the other hand, the RockShox Super Deluxe is a slightly more budget-friendly option with fewer tuning options but still offers solid performance for the average rider.
Conclusion
The Öhlins TTXAir 2.1 rear shock is a top-tier suspension component that offers a great balance of performance, adjustability, and durability. By following this guide, you can ensure that your shock remains in excellent condition, providing optimal performance on every ride. Regular maintenance, proper installation, and adjustments to air pressure and damping settings will help you get the most out of your TTXAir 2.1, making it a worthy investment for serious cyclists.
