The Öhlins STX22 Air Rear Shock is a high-performance suspension component designed to offer a smooth, controlled ride for serious cyclists. It stands out due to its advanced technology, ease of use, and versatility across various bike setups. This guide will walk you through the installation, maintenance, troubleshooting, optimization, and comparison of the STX22 Air Rear Shock, ensuring that you get the most out of this precision-engineered product.

Installation of the STX22 Air Rear Shock

Installing the STX22 Air Rear Shock is a straightforward process, but it requires attention to detail to ensure optimal performance. The shock should be mounted securely and calibrated to your bike’s specifications.

Steps for Installation:

1. Positioning the Shock: Ensure the shock is aligned with the rear triangle of your bike frame. The STX22 Air shock is designed for both full suspension and enduro bikes, so confirm that it fits within the frame’s shock mount.
2. Secure the Shock: Using the appropriate hardware, secure the top and bottom eyelets of the shock to the bike frame. Tighten the bolts to the manufacturer’s recommended torque settings.
3. Install the Air Sleeve: The STX22 Air uses an air sleeve to control compression and rebound. Make sure the air sleeve is correctly installed and seated before inflating.
4. Air Pressure Setup: Using a shock pump, set the recommended air pressure based on the rider’s weight and riding style. The air pressure will directly affect how the shock behaves, so it is crucial to get this right for a balanced ride.
5. Final Checks: Before riding, ensure that all bolts are properly tightened and that the shock is free from any obstructions or movement when in use.

Adjustment and Fine-Tuning

Once installed, the STX22 Air Rear Shock offers several adjustment options to tailor the suspension to your riding style. Fine-tuning these adjustments is essential to achieving maximum comfort and performance.

Key Adjustment Features:

• Rebound Damping: This feature controls how quickly the shock returns after compression. It is critical for ensuring that the bike doesn’t bounce too much after hitting obstacles. Adjust the rebound knob to find the balance that suits your riding preferences.
• Compression Damping: The STX22 Air allows you to adjust the compression to suit the terrain. For smoother trails, a lower compression setting will provide more sensitivity, while harsher terrain may require a stiffer compression setting to prevent bottoming out.
• Air Pressure: As mentioned during installation, air pressure is one of the most important factors in adjusting the shock. Riders can fine-tune this based on their weight and the conditions they are riding in.

Troubleshooting Common Set-Up Issues

While the STX22 Air Rear Shock is a reliable component, there are a few common issues riders may face during setup. Addressing these problems quickly will ensure a safe and enjoyable ride.

1. Insufficient Travel or Bottoming Out:

• Solution: If the shock is bottoming out, it may be under-inflated. Increase the air pressure slightly to provide more support. Alternatively, adjust the compression damping to handle larger impacts better.

2. Sag Issues:

• Solution: If you notice excessive sag, the shock may have too much air pressure. Reducing the air pressure in small increments can resolve this issue and restore proper ride feel.

3. Poor Rebound Control:

• Solution: If the shock feels bouncy, adjust the rebound damping to slow the return. Alternatively, check for any air leaks in the shock, as these can affect the rebound functionality.

Customization and Optimization for Better Performance

The STX22 Air Rear Shock offers various ways to customize its performance based on your specific needs. Whether you’re looking for more plush suspension or greater control, these tips can help you optimize the shock’s performance.

1. Rider Weight: The air pressure should be adjusted according to the rider’s weight. A heavier rider will need a higher air pressure to achieve proper sag, while a lighter rider will require less air to prevent over-sagging.

2. Terrain Adaptation: Adjust the shock’s settings to match the terrain you will be riding on. For example, soft trails or cross-country routes may benefit from a softer compression setting, while technical descents will require a stiffer setup to handle big hits and prevent bottoming out.

3. Rebound and Compression Tuning: Customize the rebound and compression settings based on your riding preferences. Some riders may prefer a quicker rebound for smoother flow, while others may need more damping to prevent excessive bounce on technical terrain.

Comparing the STX22 Air Rear Shock to Similar Models

When choosing a rear shock, it’s important to compare models that offer similar performance characteristics. The STX22 Air stands out due to its excellent balance of price, performance, and durability. Let’s compare it to a few similar models to see how it stacks up.

• Fox Float X2: The Fox Float X2 is a popular choice among enduro riders, offering a wider range of adjustability than the STX22 Air. However, the STX22 Air offers a more refined performance on smoother trails and requires less maintenance. It is also lighter, making it a better choice for riders looking for efficiency.
• RockShox Super Deluxe: The RockShox Super Deluxe is another comparable model. While it offers similar air spring systems and adjustability, the STX22 Air’s unique dual-compartment air chamber provides superior small-bump sensitivity and control. Additionally, Öhlins’ renowned hydraulic damping system gives the STX22 Air a smoother, more controlled feel over rough terrain.

Overall, the STX22 Air provides a balance between weight, performance, and adjustability that appeals to riders seeking a responsive, versatile shock for various disciplines.

Compatibility with Other Drivetrain Components

The STX22 Air Rear Shock is designed to work seamlessly with a variety of drivetrain components. However, to ensure optimal performance, it is crucial to confirm that the shock is compatible with your bike’s suspension platform, rear triangle, and overall geometry.

• Linkage and Frame Compatibility: The shock’s dimensions, stroke length, and mounting hardware must match your bike’s rear suspension setup. Check the bike frame specifications to ensure the STX22 Air fits properly and offers the desired travel range.
• Suspension Setup Integration: The STX22 Air can be paired with any standard drivetrain, but it works best when the entire bike setup (front fork, wheels, and tires) is balanced in terms of performance. For instance, pairing it with an Öhlins front fork ensures smooth integration and consistent handling.

The STX22 Air Rear Shock is an outstanding choice for riders who want a high-performance, adjustable shock that performs exceptionally well in a variety of conditions. With proper installation, adjustment, and maintenance, this rear shock can significantly enhance your riding experience, whether you’re tackling cross-country terrain or challenging enduro trails. By following the troubleshooting steps, optimizing the shock for your needs, and ensuring compatibility with other components, you’ll be able to maximize the STX22 Air’s performance on every ride.
