Installation of the TTX1Air Rear Shock
The installation of the TTX1Air rear shock requires precision to ensure the correct setup and optimal performance.
Step 1: Remove the Existing Shock
- If replacing an existing shock, first remove the rear wheel and disengage any cables that may be obstructing access.
- Use a 5mm Allen wrench [paid link] to remove the bolts securing the shock to the frame. Keep the hardware for later use.
Step 2: Install the New TTX1Air Shock
- Position the new TTX1Air rear shock in the frame’s shock mounts.
- Use the provided bolts to attach the shock, ensuring that the shock is correctly aligned with the mounts.
- Tighten the bolts with a torque wrench [paid link], ensuring each bolt is tightened to the manufacturer’s recommended specifications.
Step 3: Adjust the Air Pressure
- Use a shock pump to set the air pressure in the shock based on your weight and riding style. Start with the manufacturer’s recommended baseline and adjust accordingly.
Step 4: Recheck Mounts and Pressure
- Double-check that the shock is securely fastened and that the air pressure is consistent before reinstalling the rear wheel.
Adjustment of the TTX1Air Rear Shock
The TTX1Air rear shock offers multiple adjustment options, enabling riders to fine-tune their suspension setup for optimal performance.
Rebound Adjustment
- The rebound setting controls the shock’s ability to return after compression. Turning the rebound knob clockwise will slow down the return, while turning it counterclockwise will speed it up.
- For most riders, the ideal rebound setting is one that allows the shock to return to its normal position without any “bouncing” effect. Test the rebound by cycling the suspension through a few compressions.
Compression Adjustments
The TTX1Air features two types of compression settings: high-speed and low-speed. Here’s how to adjust them:
- Low-Speed Compression: This controls the shock’s response to slower movements, such as pedaling or small impacts. Adjust this by turning the knob near the shock body. Increase low-speed compression to reduce the shock’s sensitivity to small bumps and pedaling forces.
- High-Speed Compression: This adjusts the shock’s response to larger impacts, such as drops or hits from rough terrain. Use the high-speed compression dial to control how the shock absorbs high-impact forces. Increasing the compression will make the shock firmer, while decreasing it allows for better absorption.
Air Pressure Adjustment
- Adjusting the air pressure helps you dial in the shock’s sag, which is the amount the shock compresses under your body weight. Refer to Öhlins’ guidelines for the recommended air pressure based on your weight.
- For optimal performance, aim for around 25-30% sag for trail and all-mountain riding. Adjusting the air pressure can also affect the overall feel of the bike, making it more plush or more firm depending on the desired effect.
Maintenance of the TTX1Air Rear Shock
Regular maintenance is critical to keep the TTX1Air rear shock performing at its best. Follow these guidelines to ensure longevity and smooth operation.
Cleaning and Inspection
- After each ride, wipe down the shock with a soft cloth to remove dirt and debris.
- Inspect the shock for any signs of damage, leaks, or wear, particularly around the seals and piston. If you notice any oil leakage, the seals may need to be replaced.
- Check for any frame interference with the shock, particularly in the suspension linkage area. Ensure that the shock moves freely without any obstruction.
Service Intervals
- Air Spring Maintenance: It’s recommended to check and maintain the air spring every 100 hours of riding or once a season, whichever comes first.
- Rebuild: Depending on usage, consider a full rebuild every 200-300 hours to keep the damping system working optimally. This process typically involves disassembling the shock, cleaning internal components, and replacing worn seals or oil.
Troubleshooting Common Issues with the TTX1Air Rear Shock
While the TTX1Air rear shock is a reliable and high-performance component, riders may occasionally experience issues. Below are some common problems and their solutions:
Shock Feels Too Soft or Too Hard
- Solution: If the shock feels too soft or too firm, first check the air pressure. Adjust the pressure according to your body weight and the terrain you’re riding. Additionally, check the compression settings to ensure they are properly tuned for your riding style.
Rebound Is Too Slow or Too Fast
- Solution: If the rebound feels too slow (causing a “bouncy” feel) or too fast, adjust the rebound knob to find the optimal setting. Typically, 10-15 clicks from the fully closed position will give you a good starting point.
Leaking Oil or Air
- Solution: Oil or air leaks can occur due to worn seals. Inspect the shock for visible signs of leakage. If necessary, replace the seals or have the shock serviced by a professional.
Customization and Optimization for Better Performance
The TTX1Air rear shock is highly customizable, offering riders the ability to tailor their suspension setup for a wide range of conditions. Here are some tips to optimize the shock’s performance:
Fine-Tuning the Rebound and Compression
- Experiment with different rebound and compression settings depending on your riding terrain. On rough, technical trails, a slower rebound and more sensitive compression may be beneficial. On smoother trails, you can adjust for a firmer setup to increase pedaling efficiency.
Using Air Pressure for Adjusting Ride Feel
- Air pressure can dramatically change the feel of the shock. For aggressive riders, a firmer air spring may provide more support on larger hits, while a softer air spring will offer a more plush, forgiving ride.
Collaborating with Your Local Shop
- Working with a local bike shop to dial in your TTX1Air shock based on your specific riding style and terrain can be immensely beneficial. They can help you determine the best settings for your weight, skill level, and the trails you ride.
Comparison with Similar Models
When choosing a rear shock, it’s essential to understand how the TTX1Air stacks up against its competitors. Compared to similar shocks, such as the Fox Float X or RockShox Super Deluxe, the TTX1Air stands out due to its superior damping system and fully adjustable features. Riders looking for maximum customization and a more controlled ride often prefer the TTX1Air for its fine-tuned adjustability.
Compatibility with Other Drivetrain Components
The TTX1Air rear shock is compatible with a wide variety of modern mountain bike frames. However, it’s essential to check that your bike’s rear suspension linkage can accommodate the specific dimensions and stroke length of the shock. Additionally, if you’re upgrading from a coil shock, ensure that your frame can support the reduced weight of the air shock without compromising performance.
By paying close attention to these factors, riders can ensure that the TTX1Air integrates seamlessly into their setup, providing exceptional performance across different riding conditions.
