Öhlins is renowned for producing high-performance suspension components, and the TTX1Air rear shock is no exception. Designed for mountain bikers and road cyclists seeking superior damping performance and durability, the TTX1Air offers a perfect balance of comfort, control, and responsiveness. However, like any advanced component, it requires regular maintenance to perform at its best. This guide will provide you with detailed instructions on how to maintain your TTX1Air rear shock, troubleshoot common issues, and optimize its performance to ensure a smooth and safe ride.

Tools Required

• Shock pump (compatible with Öhlins TTX1Air)
• Allen wrenches [paid link] (various sizes)
• Torque wrench [paid link]
• O-ring grease
• 5mm hex key [paid link]
• Soft cloths or lint-free rags
• Suspension fluid (Öhlins recommended)
• Isopropyl alcohol (for cleaning)
• Sealant for air can (if necessary)

Routine Maintenance and Servicing

1. Cleaning the TTX1Air Rear Shock

Routine cleaning of your TTX1Air rear shock is crucial to maintaining its longevity and performance. After each ride, especially in muddy or wet conditions, follow these steps:

• Step 1: Use a soft cloth or a lint-free rag to wipe down the shock body and shaft. Be sure to remove any dirt, debris, and moisture that might have accumulated during your ride.
• Step 2: Pay close attention to the seals and dust wipers, as dirt can cause excessive wear on these components, leading to air or oil leakage.
• Step 3: If necessary, use a small amount of isopropyl alcohol to gently clean the shock’s moving parts, but avoid using harsh chemicals that could damage the seals.

2. Inspecting the Shock for Damage

Before each ride, visually inspect your TTX1Air rear shock for any signs of damage, including:

• Check for oil leaks: If you notice oil around the shock body or on the shock shaft, it may indicate a seal or internal issue that requires attention.
• Inspect the shock shaft and body for scratches: Deep scratches can compromise the shock’s performance by creating areas where dirt can accumulate, which can further damage the seals or cause wear.
• Examine the mounting hardware: Ensure the shock’s mounting bolts are tight and secure. Loose bolts can cause instability, impacting your ride quality and safety.

3. Air Pressure Check

The air pressure in your TTX1Air rear shock plays a vital role in achieving the optimal ride feel and maintaining shock performance. To check and adjust the air pressure:

• Step 1: Attach a shock pump to the air valve on the rear shock.
• Step 2: Set the air pressure according to the manufacturer’s recommendation, which is typically found in the user manual or Öhlins website.
• Step 3: Pressurize the shock gradually, monitoring the gauge to avoid over-inflating. Once you reach the desired pressure, detach the shock pump and ensure the valve is securely closed.

Regularly checking and adjusting the air pressure based on your weight, riding style, and terrain will help optimize the shock’s performance.

4. Lubricating Seals and Bushings

Maintaining the seals and bushings is essential for ensuring the smooth functioning of your TTX1Air rear shock. Here’s how to lubricate these components:

• Step 1: Clean the shock’s seals using a soft cloth or brush to remove any dirt or debris.
• Step 2: Apply a small amount of O-ring grease to the seals and bushings to reduce friction and enhance their longevity.
• Step 3: Rotate the shock shaft a few times to distribute the grease evenly across the seals and bushings.

It is essential to avoid over-greasing, as this can attract more dirt and debris. A thin layer of grease is all that is required.

Troubleshooting Common TTX1Air Rear Shock Issues

1. Air Leaks

If you notice a drop in air pressure, or if the shock doesn’t feel responsive, there may be an air leak. Here’s how to address it:

• Step 1: Inspect the air valve and surrounding seals for damage or debris.
• Step 2: If you find damage to the air valve or seals, consider replacing them with Öhlins-approved parts.
• Step 3: If the leak persists, the internal seals or the air can may require a rebuild or professional servicing.

2. Sag Issues

If you’re experiencing too much sag or not enough, adjusting the air pressure and rebound settings can often resolve this:

• Step 1: Check the air pressure and adjust it according to your weight and riding style.
• Step 2: If sag persists, inspect the internal damping components, as they may need adjustment or servicing.

3. Poor Rebound Performance

If the shock feels slow to return after compression or doesn’t return smoothly, it may indicate an issue with the rebound adjustment or internal damping:

• Step 1: Check the rebound dial settings. Ensure that the rebound is not set too slow.
• Step 2: If adjusting the rebound dial does not resolve the issue, internal oil or fluid may have degraded and need to be replaced.

Customization and Optimization for Performance

1. Adjusting the Rebound Damping

Fine-tuning the rebound damping on your TTX1Air rear shock allows you to adjust how quickly the shock returns after compression. To optimize performance:

• Step 1: Set the rebound damping to your preferred setting by rotating the rebound knob.
• Step 2: Test the shock by bouncing on the bike and adjusting until you find the right balance of control and comfort.

A faster rebound will offer a more responsive feel, while a slower rebound is suited for aggressive riding and technical descents where more control is necessary.

2. Adjusting the Compression Damping

The compression damping controls how the shock compresses under load, and adjusting it will affect the bike’s performance when encountering rough terrain:

• Step 1: Use the compression dial to adjust the shock’s compression. This can be done on both the low-speed and high-speed compression settings.
• Step 2: For smoother terrain, reduce the compression damping for a softer feel. For more aggressive terrain, increase the compression damping to prevent bottoming out.

Experimenting with both low-speed and high-speed settings allows you to fine-tune the shock for specific types of riding, such as cross-country, trail, or downhill.

Compatibility with Other Drivetrain Components

The Öhlins TTX1Air rear shock is designed to integrate seamlessly with various bike frame geometries and drivetrain components. However, it is important to ensure that the shock’s specifications are compatible with your bike frame, including the shock length, stroke, and mounting hardware.

• Frame Compatibility: Before installation, check that your frame supports the TTX1Air’s shock length and stroke. Some frames may require an adapter to ensure proper fitment.
• Drivetrain Compatibility: The shock works well with most modern drivetrains, but it’s always advisable to ensure the rear shock’s action complements your specific drivetrain, especially for more demanding riding conditions like racing or heavy trail use.

Conclusion

Proper maintenance of your Öhlins TTX1Air rear shock ensures that you get the most out of its performance and longevity. Regularly cleaning, inspecting, and adjusting the shock according to your riding conditions will not only improve your ride quality but also help prevent costly repairs down the line. With the right care, the TTX1Air will continue to provide superior performance, whether you are riding on smooth roads or rugged trails.
