The Öhlins STX22 Coil rear shock is designed to deliver exceptional performance and reliability for riders seeking a superior suspension experience. Its high-quality build, precise adjustability, and durability make it a preferred choice for serious cyclists. In this article, we’ll dive deep into the STX22 Coil’s installation, maintenance, troubleshooting, and performance optimization. We’ll also compare it to similar models to help riders understand why the STX22 Coil may be the best option for their bike setup.
Installation of the STX22 Coil Rear Shock
Installing the Öhlins STX22 Coil rear shock requires a careful approach to ensure proper alignment and performance. The following steps guide you through the installation process:
- Remove the Existing Rear Shock
Begin by removing the existing rear shock from your bike. This typically involves detaching the shock from both the upper and lower mounts. Be sure to keep track of any washers, bolts, or spacers as they may be reused. - Prepare the Mounting Area
Clean the mounting points thoroughly to ensure the new shock is properly seated. Use a soft cloth to wipe down any dirt or grease from the frame and shock mounts. - Install the STX22 Coil Shock
Position the Öhlins STX22 Coil shock onto the mount, ensuring that the shock’s eyelets align perfectly with the mount holes. Tighten the bolts to the manufacturer’s recommended torque settings to avoid over-tightening or under-tightening. - Install the Coil Spring
Attach the coil spring to the shock body. Make sure it is seated properly on the shock’s spring perch. Follow the manufacturer’s instructions on setting the spring preload. - Adjust the Spring Rate and Compression Settings
Once the shock is mounted, set the spring rate according to your rider weight and riding style. Adjust the compression and rebound settings based on your preferred ride characteristics. - Perform a Test Ride
After installation, perform a test ride to check for proper function. Listen for any unusual noises or signs of misalignment. Adjust the settings as needed for optimal performance.
Adjustment and Maintenance of the STX22 Coil Rear Shock
Maintaining the STX22 Coil rear shock is essential for ensuring its longevity and peak performance. Regular adjustments and care will help riders optimize their setup and maintain a smooth ride.
Compression and Rebound Adjustment
The STX22 Coil shock features both compression and rebound adjustments, which allow you to tailor the ride feel to your preference.
- Compression Adjustments: The compression adjustment knob controls how the shock compresses under load. This affects how the shock performs on impacts and how much energy is absorbed during high-speed descents or technical sections.
- Rebound Adjustments: The rebound control knob regulates the speed at which the shock extends after compression. This affects how quickly the shock returns to its normal position after an impact. Proper rebound settings ensure that the shock does not “pack down” or “top out” on successive hits.
Regular Maintenance
- Lubrication: Ensure that the shock’s moving parts are well-lubricated to reduce friction. Use a bike-specific suspension grease on the shock’s mounting eyelets during regular maintenance.
- Clean the Shock: After each ride, wipe down the shock to remove dirt and debris. Be cautious not to get water into the shock’s internal components.
- Inspect for Damage: Regularly check the shock for any signs of wear, such as leaking oil, worn seals, or dents in the shock body. If any damage is found, contact a certified technician to service the shock.
Troubleshooting Common Set-Up Issues
While the Öhlins STX22 Coil rear shock is known for its reliability, like any suspension component, it can present some issues if not properly set up or maintained. Here are common problems and their solutions:
- Excessive Bottoming Out
If the shock is bottoming out frequently, this may indicate that the compression damping is too soft or that the spring rate is too low. Adjust the compression settings to a stiffer setting or replace the coil with one that has a higher spring rate. - Harsh Ride Quality
A ride that feels overly harsh could be due to the rebound being set too fast or the compression being too stiff. Adjust both the compression and rebound settings to soften the ride. Consider experimenting with different spring rates to match your riding style. - Loss of Air Pressure (if applicable)
If the STX22 Coil starts to lose pressure, check the shock’s seals for leaks. If any leaks are detected, the seals may need to be replaced by a professional technician.
Customization and Optimization for Better Performance
The Öhlins STX22 Coil rear shock is designed for riders who demand precision and customization. Riders can fine-tune the shock to achieve the best possible ride quality by making a few adjustments.
- Spring Rate Optimization
The right spring rate is essential for achieving optimal ride performance. Riders should select a spring that is appropriate for their weight and riding style. The STX22 Coil offers a variety of springs, allowing riders to customize their ride experience for both comfort and performance. - Adjusting for Terrain
For riders who tackle diverse terrains, adjusting the compression damping and rebound settings for different conditions can greatly improve performance. Softer compression and rebound settings may be more suitable for technical trails, while stiffer settings are beneficial for high-speed descents and smoother roads. - Setting the Preload
Proper spring preload ensures that the shock has the correct sag. This is essential for maintaining optimal suspension performance throughout the ride. The STX22 Coil offers a wide range of preload adjustments to help riders dial in their setup.
Comparison with Other Rear Shocks
When comparing the Öhlins STX22 Coil to other rear shocks on the market, it stands out due to its precision, quality, and adjustability. However, it’s important to consider how it stacks up against competitors in the same category.
- Fox DHX2 Coil: The Fox DHX2 Coil is another popular rear shock that offers high adjustability and performance. While both the DHX2 and the STX22 Coil feature adjustable compression and rebound damping, the Öhlins shock tends to offer more precise tuning with a slightly smoother ride feel. The DHX2 may be a better option for riders who prioritize ease of maintenance and availability of aftermarket parts.
- RockShox Super Deluxe Coil: The RockShox Super Deluxe Coil is known for its affordability and solid performance. However, the STX22 Coil tends to be more refined in terms of suspension feel, with a greater range of customization options. Riders looking for high-end performance in more technical rides may prefer the Öhlins shock for its better overall ride quality.
Compatibility with Other Drivetrain Components
The Öhlins STX22 Coil rear shock is compatible with most modern bike frames and drivetrain systems. However, it’s important to ensure that the shock’s length and mounting hardware match your bike’s specifications. Pay attention to the eyelet size and shock length to avoid compatibility issues.
- Mounting System Compatibility: The STX22 Coil is designed to work with both traditional and metric-sized mounts. Verify your bike’s mount specifications before purchasing to ensure proper fitment.
- Integration with Other Suspension Components: The STX22 Coil integrates well with other high-end suspension components from Öhlins and other brands. Riders can mix and match components as needed to optimize their overall bike setup.
