our TriAir2 Rear Shock

The installation process of the TriAir2 rear shock is straightforward, but it requires careful attention to detail to ensure optimal performance. Here’s a step-by-step guide to properly install the shock on your bike:

1. Remove the Old Shock (if applicable): If you are replacing an old shock, use a 5mm Allen wrench [paid link] to remove the bolts holding the shock in place. Be sure to keep these bolts as they will be reused.
2. Check Frame Compatibility: Before installing the TriAir2, ensure that your bike’s frame is compatible with the shock. The shock features a specific eye-to-eye measurement and stroke length. Verify these dimensions match your frame’s specifications.
3. Mount the Shock: Place the TriAir2 into the frame’s shock mounts. The shock should fit snugly into place. Insert the bolts through the eyelets of the shock and the frame’s mounting points. Tighten the bolts evenly to the manufacturer’s torque specifications, which can typically be found in the shock’s manual.
4. Install the Air Sleeve: Attach the air sleeve to the shock body if it is not pre-installed. Make sure the sleeve is properly aligned and secured.
5. Check for Movement: Once installed, check the shock for any excessive movement. The shock should remain firmly in place without any play.
6. Inflate to Proper Pressure: Use a shock pump to inflate the shock to the recommended air pressure. Refer to the shock’s manual or the SR Suntour website for specific pressure recommendations based on rider weight and riding style.

Adjustments and Tuning for Optimal Performance

One of the standout features of the TriAir2 rear shock is its extensive adjustability. Riders can fine-tune several aspects of the shock to suit their riding style and terrain. These adjustments allow you to tailor the shock’s performance to achieve a smoother, more controlled ride.

Rebound Adjustment

The TriAir2 is equipped with a rebound adjuster, allowing riders to control how quickly the shock returns after compression. A slower rebound setting is suitable for rougher, technical trails, while a faster rebound is ideal for smoother trails and racing conditions.

1. Turn the rebound knob clockwise to slow down the rebound for increased control on bumpy terrain.
2. Turn the rebound knob counterclockwise to speed up the rebound for a more lively feel on smoother trails.

Compression Adjustment

The compression adjuster on the TriAir2 allows you to adjust how much resistance the shock provides during compression. This is important for controlling bottoming out on larger hits or maintaining comfort on less aggressive rides.

1. Turn the compression knob clockwise for more resistance and a firmer ride, which is ideal for aggressive riders or rough trails.
2. Turn the compression knob counterclockwise to decrease resistance and provide a smoother, more comfortable ride over moderate terrain.

Air Pressure Adjustment

Setting the correct air pressure is crucial for optimizing performance. Riders should adjust the air pressure based on their weight and the terrain they plan to ride. Too little air pressure will lead to bottoming out, while too much pressure can make the shock too stiff and uncomfortable.

1. Use a shock pump to set the air pressure within the recommended range.
2. For heavy riders or rougher trails, consider increasing the air pressure slightly to maintain proper suspension performance.

Maintenance of the SR Suntour TriAir2 Rear Shock

Regular maintenance is essential for keeping your TriAir2 rear shock performing at its best. SR Suntour recommends servicing the shock at least once a year, or more frequently depending on usage and riding conditions.

Cleaning and Inspection

1. Clean the Shock: After every ride, wipe down the shock with a soft, damp cloth to remove dirt and debris.
2. Check for Leaks: Inspect the shock’s seals and air sleeve for any signs of leakage. If air is escaping, the seals may need replacement.
3. Inspect the Mounting Points: Ensure the shock mounting bolts are tight and that the shock is properly secured to the frame.

Servicing the Shock

1. Air Sleeve Service: The air sleeve of the TriAir2 should be serviced periodically. Remove the air sleeve and clean the interior components, lubricating as needed.
2. Oil Bath: Over time, the shock oil may degrade, leading to reduced performance. Regularly changing the shock oil will ensure smooth performance and help to extend the life of the shock.
3. Seals and Dampers: Check the seals regularly and replace them when necessary to prevent air leaks and ensure consistent damping performance.

Troubleshooting Common Set-Up Issues

While the TriAir2 is a highly reliable shock, there are a few common issues riders may encounter during set-up or use. Here’s how to troubleshoot these issues:

Issue: Bottoming Out

If the shock is bottoming out too frequently, it may indicate an issue with the air pressure or compression settings.

• Solution: Increase the air pressure slightly and adjust the compression settings for a firmer ride. Ensure that you are within the recommended air pressure range for your weight.

Issue: No Rebound Control

If the rebound adjustment does not seem to affect the shock, it may indicate an issue with the damper.

• Solution: Check for any blockages in the damper and ensure that the rebound adjuster is functioning properly. If the problem persists, the damper may require servicing.

Issue: Excessive Stiffness or Lack of Support

If the shock feels too stiff or does not provide adequate support, it may be over-pressurized.

• Solution: Lower the air pressure to a more appropriate level for your riding style and weight.

Customization and Optimization for Better Performance

The TriAir2 can be optimized for different types of riding by adjusting several key settings. Here are some tips for customizing the shock for your specific needs:

• For Cross-Country Riding: Reduce the air pressure slightly and dial in the compression for a softer, more responsive feel that is ideal for smooth trails and long-distance rides.
• For Enduro or Downhill Riding: Increase the air pressure and tighten the compression to handle larger hits and more aggressive terrain. The TriAir2’s damping adjustments will help maintain control during rough descents.

Compatibility with Other Drivetrain Components

The SR Suntour TriAir2 rear shock is designed to be compatible with a variety of mountain bike frames, but it is essential to ensure compatibility with your bike’s overall drivetrain and suspension system. Pay close attention to the following:

• Frame Mounting: The TriAir2 is available in several eye-to-eye and stroke lengths to accommodate different frame designs. Ensure the shock’s dimensions match your bike’s requirements.
• Suspension Linkage: Check that the suspension linkage on your bike is designed to work with air shocks. The TriAir2 performs best when paired with a linkage that provides an efficient leverage ratio for consistent shock performance.
