Tools Required
To properly install and maintain the Shout Message Linkage, you’ll need the following tools:
- Torque wrench [paid link]
- 5mm and 6mm Allen wrenches [paid link]
- 10mm and 15mm open-ended wrenches
- Grease
- Suspension fluid (specific to the linkage)
- Locktite (for bolt threads)
- Bike stand [paid link] (optional but recommended)
- Clean cloths or rags
- Chain breaker tool (if required for removal of parts)
Installation of the Shout Message Linkage
Installing the Shout Message Linkage is a straightforward process, but it requires precision to ensure optimal performance. Follow these steps to install it correctly:
- Prepare the Bike: Start by securing the bike in a work stand to ensure stability during the installation. This will make the process easier and safer.
- Remove the Existing Linkage: If your bike already has a rear linkage installed, carefully remove it by first loosening the bolts that hold it in place. Keep all the bolts and fasteners, as you’ll need them for the new installation.
- Apply Grease: Before installing the Shout Message Linkage, apply a small amount of grease to the pivot points and bolt threads. This helps to prevent corrosion and ensures smooth movement of the linkage.
- Install the Shout Message Linkage: Position the Shout Message Linkage in place. Align the holes of the linkage with the corresponding mounting points on your frame and rear shock. Insert the bolts and tighten them using a torque wrench [paid link]. Be sure to follow the manufacturer’s recommended torque values for the bolts to avoid over-tightening.
- Check for Proper Movement: Once the linkage is installed, manually cycle the rear suspension to ensure the linkage moves smoothly without any interference. If the movement feels stiff or there’s any binding, double-check the installation for proper alignment.
- Final Tightening: Double-check all bolts for proper torque and re-tighten them if necessary.
Adjusting the Shout Message Linkage for Optimal Performance
After installing the Shout Message Linkage, you may need to make a few adjustments to tailor it to your riding style and preferences. Here’s how you can fine-tune its performance:
Suspension Setup
The Shout Message Linkage is designed to work with specific rear shocks, so ensuring your shock is correctly set up for your weight and riding style is essential. Follow the shock manufacturer’s setup recommendations and adjust the air pressure, compression, and rebound settings accordingly.
Fine-tuning Sag
Adjust the sag on your rear suspension to ensure it is within the recommended range. The Shout Message Linkage may alter the way your suspension behaves, so it’s important to check the sag regularly.
- Sit on the bike while it is in a normal riding position.
- Measure the amount the shock compresses under your weight.
- Adjust the air pressure or damping settings on your shock to achieve the desired sag. For most riders, a sag of about 25-30% of the shock’s total travel is ideal.
Linkage Tuning
The Shout Message Linkage offers adjustable geometry, allowing you to modify the feel of your rear suspension. By changing the position of the shock mounting point, you can adjust the leverage ratio, which affects how the suspension absorbs bumps. Experiment with different settings to find the one that works best for your riding style, whether you prefer a more aggressive setup for downhill or a more plush feel for cross-country riding.
Maintenance of the Shout Message Linkage
Proper maintenance is crucial to keep the Shout Message Linkage functioning smoothly for years to come. Follow these guidelines to maintain your linkage:
Cleaning
Regularly clean the linkage to remove dirt, mud, and debris that may accumulate in the pivots and bearings. Use a clean cloth or rag and mild soap to wipe down the components. Avoid using high-pressure water hoses, as they can force dirt into the bearings, potentially causing damage.
Lubrication
Ensure that the pivot points on the linkage are adequately lubricated. Apply a small amount of grease or suspension fluid to the pivots to reduce friction and prevent wear. Check these points regularly, particularly after riding in wet or muddy conditions.
Bearing Inspection
The bearings in the Shout Message Linkage should be inspected for smoothness and wear. If you notice any roughness, noise, or play in the linkage, it’s time to replace the bearings. This can be done by removing the linkage and pressing out the old bearings with a bearing press [paid link] tool. Always replace bearings with the manufacturer’s recommended parts for optimal performance.
Suspension Fluid
If the linkage is equipped with suspension-specific components, periodically check the suspension fluid levels and replace the fluid as recommended by the manufacturer. This ensures the suspension continues to operate at its peak [paid link] efficiency.
Troubleshooting Common Issues with the Shout Message Linkage
While the Shout Message Linkage is designed to provide excellent performance, there are a few common issues that may arise. Here’s how to troubleshoot them:
Noisy Suspension
If your suspension is making excessive noise, it could be a sign of insufficient lubrication or worn-out bearings. First, check the pivot points for proper lubrication and reapply grease if needed. If the noise persists, inspect the bearings for wear and replace them if necessary.
Stiff or Sticky Suspension
If the rear suspension feels stiff or sticky, it may be due to incorrect shock settings or a lack of lubrication in the linkage. Adjust the air pressure and damping settings on your rear shock, and ensure the pivot points are properly greased. If the issue continues, inspect the linkage for misalignment or damaged components.
Suspension Sag Issues
If you notice that the rear suspension sag is too high or too low, it could be due to incorrect shock setup or a worn-out shock. Recheck the shock’s air pressure, compression, and rebound settings. If the shock is damaged, consider replacing it with one that is compatible with the Shout Message Linkage.
Customization and Optimization
The Shout Message Linkage offers several ways to customize and optimize your bike’s suspension to match your riding style. Here are a few ways to further enhance your ride:
- Leverage Ratio Adjustment: The linkage allows for changes in the leverage ratio, which can affect how the shock feels during compression. Experiment with different settings to find a setup that provides the ideal balance between comfort and performance.
- Geometry Modifications: Adjusting the geometry of the rear suspension via the linkage can change your bike’s handling. If you prefer more stability at high speeds, you can adjust the geometry to slacken the head angle or lower the bottom bracket height. Conversely, for a more agile and responsive bike, steepen the head angle or raise the bottom bracket height.
- Shock Tuning: Since the Shout Message Linkage works with specific rear shocks, it’s important to choose a shock that complements your riding style. Customizing the shock settings, such as rebound damping and compression, can make a big difference in the overall ride feel.
Compatibility with Other Drivetrain Components
The Shout Message Linkage is designed to be compatible with a wide range of modern drivetrain components. However, ensuring compatibility with your specific frame and shock is essential for optimal performance.
Rear Shock Compatibility
The Shout Message Linkage works best with rear shocks that have adjustable air pressure and damping settings. Make sure the shock you select has a suitable amount of travel to match the linkage’s design. Always check the manufacturer’s recommendations for compatibility to ensure the best performance.
Frame Compatibility
While the Shout Message Linkage is designed for a variety of bike frames, it’s important to verify that your frame has the appropriate mounting points and dimensions for proper installation. Some frames may require specific adapters or modifications for a perfect fit.
Drivetrain Compatibility
Since the linkage doesn’t affect the drivetrain directly, it’s generally compatible with any modern drivetrain. However, ensure that your rear derailleur and chainstay clearance are adequate to avoid interference with the linkage during suspension movement.
Conclusion
The Shout Message Linkage from Trust is a high-performance upgrade that can significantly improve your bike’s rear suspension. Whether you’re looking to fine-tune your ride for downhill runs or enhance comfort on cross-country trails, the Shout Message Linkage offers adjustable geometry and a smooth suspension experience. By properly installing, adjusting, and maintaining the linkage, you can enjoy a more responsive and efficient ride tailored to your unique preferences.
