Installation of the Mara Inline Trunnion Rear Shock
Installing the Mara Inline [paid link] Trunnion rear shock correctly is crucial to ensure optimal performance and safety. Follow these steps to install the shock properly:
- Remove the Old Shock (if applicable)
If you are replacing an existing shock, first remove it from the bike by loosening the bolts securing it to the frame and carefully detaching it. - Check the Shock Mounts
Ensure the shock mounts on the frame are free from any dirt, debris, or damage. Clean the mounting points to provide a secure and stable fit for the new shock. - Install the New Shock
Position the Mara Inline [paid link] Trunnion rear shock onto the frame’s mounting points. Insert the trunnion mounting bolts and tighten them to the manufacturer’s recommended torque specification. Make sure the shock is aligned correctly before fully tightening. - Check for Proper Alignment
After installation, check that the shock is aligned parallel to the frame. This will prevent undue strain on the shock during use. - Test the Installation
Before heading out on a ride, compress the shock a few times by hand to ensure it is mounted securely and functioning smoothly.
Adjustment of the Mara Inline Trunnion Rear Shock
Proper adjustment of the Mara Inline Trunnion rear shock ensures that it provides the best possible performance for your riding style and terrain. The shock features adjustable rebound and compression settings to allow for fine-tuning. Here’s how to adjust them:
- Set the Air Pressure
The Mara Inline Trunnion uses air pressure to control the shock’s performance. Use a shock pump to adjust the air pressure based on your weight and riding style. Refer to the manufacturer’s recommended pressure chart for optimal performance. - Adjust the Rebound
Rebound control regulates the shock’s return after compression. Turn the rebound dial to adjust the speed at which the shock extends after compression. A slower rebound is better for smoother terrain, while a faster rebound works better on rougher, more technical trails. - Set the Compression Damping
The compression dial adjusts how much the shock resists compression under load. Set it to your preferred level, with higher compression damping providing more control on rougher terrain and lower damping offering more comfort and flexibility. - Check the Sag
The sag setting is critical to ensure the shock is working within its optimal range. To check the sag, sit on the bike, compress the shock, and observe the amount of travel it uses. The ideal sag for most riders is around 25-30% of the shock’s total travel. - Test the Adjustments
After making your adjustments, take the bike for a test ride to ensure the shock feels responsive and provides the desired level of comfort and control.
Preventative Maintenance of the Mara Inline Trunnion Rear Shock
Routine preventative maintenance is key to keeping your Mara Inline Trunnion rear shock in top condition. Regular maintenance will not only extend the shock’s life but also ensure it performs at its best throughout your rides.
- Clean the Shock Regularly
After each ride, clean the shock with a soft cloth and mild soapy water to remove any dirt or grime. Avoid using harsh chemicals, as these can damage the shock’s seals. Make sure to dry the shock thoroughly after cleaning. - Lubricate the Shock Bushings
Apply a light layer of lubricant to the shock bushings where the shock mounts to the frame. This will reduce friction and prevent premature wear of the bushings. Be sure to use a lubricant recommended by Manitou to avoid damaging the shock. - Check for Leaks
Regularly inspect the shock for any signs of oil or air leaks, particularly around the seals. If you notice any leaks, it is important to address the issue immediately, as this can significantly impact the shock’s performance. - Inspect the Seals
The seals on the shock are critical for keeping dirt and water out. Inspect the seals regularly for signs of wear or damage. If the seals appear worn or cracked, it is time to replace them. Properly maintained seals will ensure that the shock remains sealed from contaminants. - Service the Shock Periodically
Even with proper cleaning and lubrication, your shock will require professional servicing every 12-18 months, depending on how often you ride. During a service, the shock will be disassembled, cleaned, and re-oiled, and the seals will be replaced as needed.
Troubleshooting Common Set-Up Issues with the Mara Inline Trunnion Rear Shock
Even with regular maintenance, you may encounter issues with your Mara Inline Trunnion rear shock. Below are some common problems and how to troubleshoot them:
- Shock Not Holding Air Pressure
If the shock loses air pressure, the most likely cause is a damaged seal or valve. Inspect the shock for visible signs of leakage and replace the seals or service the shock if necessary. - Too Much or Too Little Rebound
If the rebound feels too fast or too slow despite proper adjustment, it may be a sign that the internal damper requires servicing. Over time, the oil inside the shock can degrade, leading to improper damping. A professional service will restore the shock’s damping performance. - Sag Issues
If the sag is too deep or too shallow, adjust the air pressure accordingly. However, if the sag is still problematic after adjusting the air pressure, it may indicate that the shock needs servicing, particularly if it has suffered internal damage or seal failure. - Loss of Damping Control
A lack of damping control or excessive movement during compression or rebound could be a sign that the shock’s internal oil has degraded or that the damping valves need attention. Regular servicing is essential for maintaining optimal damping performance.
Customization and Optimization for Better Performance
To get the most out of your Mara Inline Trunnion rear shock, consider the following customization and optimization tips:
- Fine-Tune Your Compression and Rebound Settings
Experiment with the compression and rebound settings based on the terrain you most frequently ride. For example, if you ride technical trails with a lot of rocks and roots, you may want to increase the compression damping to provide more control. - Use a Custom Shock Tune
If you find the stock settings don’t suit your riding style, you can work with a professional shock tuner to create a custom tune for your Mara Inline Trunnion. A custom tune can optimize the shock’s performance for your specific weight, riding style, and preferred terrain. - Upgrade the Shock Components
Manitou offers a range of upgrade options for the Mara Inline Trunnion, including different springs and higher-end dampers. Consider upgrading these components for a more responsive, higher-performance shock. - Adjust for Bike Geometry
Your bike’s geometry plays a significant role in how the rear shock performs. If you’re looking to optimize performance, consider adjusting the shock’s air pressure and damping settings to complement your bike’s geometry. This can significantly improve handling and comfort.
Compatibility with Other Drivetrain Components
The Mara Inline Trunnion rear shock is compatible with a wide range of bike frames, but it’s essential to ensure it works well with the rest of your drivetrain components. Here’s what you need to consider:
- Frame Compatibility
Ensure that your bike frame has a trunnion mount designed for the Mara Inline Trunnion shock. While the shock fits most frames with this mounting standard, always check your frame specifications before installation. - Shock Travel and Bike Geometry
Make sure the shock’s travel is suitable for your bike’s geometry. Too much or too little travel can affect the bike’s handling and overall performance. It’s crucial to balance the shock’s travel with the frame’s design to get the best ride. - Axle and Hub Compatibility
The shock works well with most standard rear axles and hubs, but it’s important to ensure that the rear axle system on your bike is compatible with the shock’s requirements for proper performance. - Braking System
Ensure that your braking system is compatible with the rear shock. Some bike setups with larger rotors or specific braking systems may require additional adjustments to ensure smooth performance without interference with the shock.
By following these guidelines, you can ensure that your Manitou Mara Inline Trunnion rear shock performs optimally and serves you well for many years to come. Regular maintenance and proper adjustments will make a significant difference in how your shock handles varying conditions and maximizes your riding experience.
