Step-by-Step Installation:

1. Remove the Old Shock: Start by removing the existing rear shock. This can typically be done by loosening the bolts that secure the shock to the frame and linkage. Carefully detach the shock while ensuring no other parts are disturbed.
2. Inspect the Mounting Points: Before installing the TTX1Air, inspect the mounting points on your bike frame for any signs of wear, debris, or damage. Clean these areas thoroughly to ensure a proper seal and prevent contamination.
3. Mount the TTX1Air Shock: Align the shock’s eyelets with the mounting points on the frame and linkage. Attach the shock by securing it with the appropriate bolts. Tighten the bolts using a torque wrench [paid link] to the manufacturer’s recommended torque settings. Avoid overtightening, as this can damage the frame or shock.
4. Attach the Air Canister: Inflate the air canister using a shock pump to the desired pressure based on your rider weight and riding style. The TTX1Air features an easy-to-use air chamber that allows for quick adjustments.
5. Check for Proper Operation: Once the shock is installed, check the rear suspension for proper movement and alignment. Push down on the bike and ensure the shock compresses and rebounds smoothly without any unusual resistance or noises.

Adjustment and Maintenance of the TTX1Air Rear Shock

The Öhlins TTX1Air rear shock offers multiple adjustment features that allow riders to tailor the suspension to their specific needs. Regular maintenance ensures that the shock performs at its best throughout its lifespan.

Key Adjustments:

1. Rebound Damping: The TTX1Air comes with an adjustable rebound damping system. This controls the speed at which the shock extends after compression. If you prefer a faster return, decrease the rebound damping. For a slower return, increase the damping.
2. Compression Damping: The shock also features a low-speed and high-speed compression adjustment. The low-speed compression affects how the shock reacts to small, slow movements (like pedaling forces), while the high-speed compression controls the reaction to more rapid impacts.
3. Air Pressure: The air pressure inside the shock determines its spring rate. Set the air pressure according to your weight, riding style, and terrain. A good starting point is to set the shock pressure for around 25-30% sag, meaning the shock compresses this amount under your weight.

Regular Maintenance:

1. Lubrication: Periodically check the seals for signs of wear and clean the shock body with a soft cloth to remove dirt and debris. Applying a small amount of shock oil to the bushings will help maintain smooth performance.
2. Air Canister Maintenance: After extended use, check for air leaks in the air chamber and re-inflate as needed. Ensure the valve cap is tightly sealed to avoid losing air pressure.
3. Inspection: Inspect the shock for any visible damage, such as cracks or dents. These can affect performance and may require professional service.

Troubleshooting Common Set-Up Issues

Even though the TTX1Air is designed to provide reliable performance, some issues may arise during installation or use. Below are common problems and solutions.

Problem 1: Excessive Sag

If you experience too much sag in the rear suspension, it may be due to insufficient air pressure in the shock. Increase the air pressure by small increments until the correct sag is achieved. Always check your shock’s pressure regularly to maintain optimal performance.

Problem 2: Harsh Ride or Lack of Sensitivity

A harsh ride or lack of sensitivity can often be linked to too much compression damping or high air pressure. Try reducing both the high and low-speed compression damping. Additionally, lowering the air pressure slightly can improve sensitivity and ride comfort.

Problem 3: Bottoming Out

If the shock bottoming out is frequent, you may need to adjust the compression settings or increase the air pressure to prevent excessive travel. Ensure that your rebound settings are not too fast, as this can affect the shock’s ability to recover properly.

Problem 4: No Rebound Action

If there is no rebound action, check the rebound damping setting. It might be set too slow, preventing the shock from returning to its neutral position. Adjust the rebound knob to a more neutral setting and test the shock’s performance.

Customization and Optimization for Better Performance

To get the most out of your Öhlins TTX1Air rear shock, it is essential to fine-tune its settings based on your riding style, weight, and terrain. Here are a few tips to optimize the shock for peak performance.

1. Tailor Air Pressure: The TTX1Air allows for precise adjustments to the air pressure, making it highly customizable. Start with a general baseline and gradually adjust the pressure for your preferred ride feel. Lighter riders may prefer a lower pressure for more sensitivity, while heavier riders may need a higher pressure for proper support.
2. Fine-Tune Compression Settings: Adjust the low-speed compression to account for pedal-induced forces. If you’re experiencing excessive bobbing or an inefficient ride, tightening the low-speed compression can help. High-speed compression adjustments are more critical for handling bigger impacts, so ensure this is set based on your typical terrain.
3. Rebound Tuning: Set the rebound damping based on the type of terrain you’re riding. For technical trails with frequent drops, slightly slower rebound damping can help keep the rear wheel in better contact with the ground. On smoother trails, a quicker rebound may feel more responsive.
