Installation of the Ario RL Rear Shock

Installing the RockShox Ario RL rear shock involves ensuring compatibility with your frame and setting it up correctly for the first time. Here are the steps to follow:

1. Prepare the frame: Ensure your frame is clean and that the shock mounting points are free of debris.
2. Install the shock: Carefully insert the Ario RL into the rear shock mount of the frame. Be sure to align the shock’s eyelets with the corresponding mounts on the frame.
3. Secure the bolts: Use a 5mm Allen wrench to tighten the mounting bolts. Be careful not to overtighten as this may damage the shock or the frame. It is essential to use a torque wrench [paid link] to apply the correct amount of torque (typically around 25-30 Nm, but consult the manufacturer’s specs).
4. Set the sag: Once the shock is mounted, use a shock pump to adjust the air pressure according to your weight and riding style. For the Ario RL, the air pressure should be set to approximately 30% of your total travel to achieve the desired sag.

Adjustment and Maintenance

Regular adjustments and maintenance of the Ario RL will ensure optimal performance throughout its lifespan. Below are the key aspects to focus on:

Air Pressure Adjustment

The Ario RL features an air spring that requires regular pressure adjustments. The correct pressure is crucial for getting the right balance between comfort and performance.

• Use a shock pump to adjust the air pressure based on your body weight and riding conditions.
• Ensure that the shock maintains its pressure between rides. If you notice a drop in pressure, it may indicate a leak or need for servicing.

Rebound Adjustment

The rebound dial on the Ario RL allows you to fine-tune the shock’s return speed. This is important for maintaining control over the bike when navigating uneven terrain.

• To adjust the rebound, simply turn the dial located at the base of the shock. Turning it clockwise slows the rebound, while turning it counterclockwise speeds it up.
• Make small adjustments, as even minor changes can significantly affect the ride quality.

Shock Lubrication

Regular lubrication is vital to prevent wear on the shock seals and ensure smooth movement of the shock shaft. You should clean and lubricate the shock at least once per season, depending on how often you ride.

• Use a soft brush and degreaser to clean the shock body, removing dirt and debris.
• Apply a light layer of suspension fluid to the shock shaft to ensure smooth operation.

Troubleshooting Common Set-Up Issues

Occasionally, you may run into issues with the Ario RL rear shock. Below are some common problems and solutions:

Loss of Air Pressure

If you notice the shock losing air pressure, it could be due to a slow leak in the shock itself or its valves. To address this:

• Inspect the Schrader valve for damage or wear and replace it if necessary.
• Ensure the valve is fully closed after each adjustment.
• Check the seals for wear. If the shock consistently loses air, it might need to be serviced by a professional mechanic.

Excessive Rebound Speed

If the rebound is too fast, you may lose control of your bike when hitting larger bumps or obstacles. To fix this:

• Turn the rebound dial clockwise to slow the rebound.
• If the problem persists, inspect the shock for any issues with internal components, such as worn-out seals or shock oil. A suspension service may be required.

Poor Shock Performance

If the shock feels soft or bottoming out too easily, it may indicate improper air pressure or insufficient rebound adjustment. To troubleshoot:

• Double-check the air pressure and adjust it according to your weight.
• Ensure the rebound is set correctly for the terrain you’re riding.
• If performance continues to degrade, inspect the shock for any leakage or internal wear.

Customization for Better Performance

The Ario RL rear shock offers a range of adjustments to fine-tune its performance based on your riding style and conditions. Customizing your shock will make a noticeable difference in the ride quality.

Adjusting for Different Riding Conditions

• For Cross-country Riding: Set the shock’s air pressure to a slightly higher level to minimize sag and improve pedaling efficiency.
• For Trail Riding: Opt for a slightly softer setting to enhance comfort and control over rough terrain. Adjust the rebound to match the speed of terrain transitions.
• For Downhill Riding: Increase the air pressure to prevent bottoming out on big impacts. Slow the rebound to ensure control when the shock extends after hitting drops.

Setting the Ideal Sag

Setting the correct sag is essential for comfort and handling. For the Ario RL, set the sag to around 30% of the total travel, but this can be adjusted based on personal preference and riding conditions. A softer sag offers more comfort and better traction, while a firmer setting provides better efficiency on smoother surfaces.

Compatibility with Other Drivetrain Components

The RockShox Ario RL is designed to be compatible with most modern road bike frames, especially those equipped with the right shock mounting points. However, it is essential to verify compatibility with other drivetrain components, especially if you’re upgrading your bike or replacing a worn-out shock.

• Mounting Compatibility: Ensure that the mounting hardware and shock eyelets of your frame are compatible with the Ario RL.
• Frame Size and Travel: The shock’s travel must align with your frame’s design for proper suspension performance. If unsure, consult your frame’s manufacturer to confirm compatibility with the Ario RL’s travel range.
• Air Spring Compatibility: The Ario RL’s air spring is compatible with most air shocks, but ensure that the shock is properly sized for your frame to avoid issues with setup or performance.

Comparison with Similar Models

When comparing the RockShox Ario RL to other rear shock models, a few key differences stand out:

• Fox Float DPS: Offers a more customizable range of adjustments, including lockout features, but may be more complex to adjust compared to the Ario RL.
• DVO Jade: Known for its durability and better performance in aggressive downhill settings. However, it is heavier than the Ario RL, making the Ario RL a better option for weight-conscious riders.
• SR Suntour Aion: Another entry-level shock with comparable performance, but the Ario RL often provides a smoother ride and requires less maintenance.

Conclusion

Maintaining the RockShox Ario RL rear shock is essential for ensuring that it continues to deliver optimal performance, whether you are an experienced rider or just starting. Regular air pressure adjustments, rebound settings, and lubrication are critical to keeping the shock in top condition. Additionally, understanding how to troubleshoot common issues and customize the shock for your specific needs will help you maximize its potential.
