The Manitou Mara Pro Trunnion [paid link] rear shock is a high-performance shock designed for serious mountain bikers and riders who demand precise handling and comfort. To ensure it performs at its best throughout its lifespan, regular preventative maintenance is crucial. This guide will walk you through the proper installation, adjustment, maintenance, troubleshooting, customization, and optimization of the Mara Pro Trunnion [paid link] shock.
Installation of Mara Pro Trunnion Rear Shock
Installing the Mara Pro [paid link] Trunnion rear shock correctly is essential for optimal performance and safety. Follow these steps carefully:
- Prepare the Bike:
- Remove the rear wheel and any components obstructing access to the shock mount.
- Clean the area around the shock mount to avoid introducing dirt and debris during installation.
- Remove the Old Shock:
- Use a 5mm Allen wrench [paid link] to unscrew the bolts holding the existing shock in place.
- Gently remove the shock from the frame, ensuring that you do not damage the mounts.
- Install the Mara Pro [paid link] Trunnion Rear Shock:
- Align the trunnion mount of the Mara Pro shock with the frame’s shock mounting points.
- Ensure the shock is properly oriented, with the damper controls facing the correct direction.
- Tighten the mounting bolts using a torque wrench [paid link]. Refer to the manufacturer’s recommended torque values to avoid over-tightening.
- Double-Check the Installation:
- Verify that all bolts are tightened securely and that the shock is positioned correctly.
- Ensure there is no interference with the frame or linkage, allowing full range of motion for the shock.
Adjustment and Customization
Proper adjustment and customization of the Mara Pro Trunnion shock can significantly enhance your riding experience. These adjustments allow you to tailor the shock’s performance to your specific riding style and conditions.
Compression and Rebound Adjustments
The Mara Pro shock features compression and rebound adjustments to fine-tune your suspension. Here’s how to adjust them:
- Rebound Adjustment:
- Adjust the rebound dial to control how quickly the shock returns to its original position after compression.
- Turn the dial clockwise to slow down the rebound and counterclockwise to speed it up. Start by setting it to the manufacturer’s recommended baseline and adjust from there based on riding feel.
- Compression Adjustment:
- The compression knob allows you to control how the shock compresses under load.
- Turn the knob clockwise for more compression (firmer ride) and counterclockwise for less compression (softer ride).
- Experiment with the compression setting to find the ideal balance between comfort and control for your riding style.
Sag Setup
Setting the correct sag is critical for ensuring the shock performs as intended. The Mara Pro shock has a recommended sag range, usually around 25-30% of the total shock stroke. To set the sag:
- Mount the bike and get into riding gear.
- Position yourself on the bike, and apply your full body weight.
- Measure the amount of shock compression from the fully extended position.
- Adjust the air pressure in the shock to achieve the desired sag. Use a shock pump to add or release air as needed.
Maintenance of Mara Pro Trunnion Rear Shock
Regular maintenance will help preserve the performance and lifespan of your Mara Pro Trunnion rear shock. Follow these steps to keep your shock in top condition.
Cleaning
After every ride, especially in muddy or wet conditions, clean the shock to prevent dirt and debris from causing damage.
- Use a soft cloth or brush to remove dirt from the shock body and mount area.
- For a deeper clean, use water and mild soap. Avoid high-pressure water, as it can force debris into the shock seals.
Lubrication
Maintaining proper lubrication on the shock’s moving parts is vital for smooth operation. Apply a light coat of suspension oil to the shock shaft and seals periodically, but avoid over-lubricating, as excess oil can attract dirt.
Air Can Service
At least once a year, perform an air can service to keep the Mara Pro shock functioning at its best.
- Remove the shock from the bike.
- Using a shock pump, release the air from the air can.
- Disassemble the shock to access the air can.
- Clean all components and inspect for any wear or damage.
- Replace the air can seals if needed and reassemble the shock.
Damper Service
The damper should be serviced every 50-100 hours of riding, depending on your usage. This service typically includes disassembling the shock to clean and lubricate the damper components, ensuring proper oil levels, and replacing seals as necessary.
Troubleshooting Common Set-Up Issues
While the Mara Pro Trunnion rear shock is designed for durability and performance, it may experience common set-up issues that can affect its operation. Here’s how to troubleshoot them:
Issue: Lack of Rebound Control
If the rebound feels too fast or too slow:
- Check the rebound dial settings. Ensure it’s not set to an extreme setting, which may prevent proper damping.
- Inspect the shock oil. Low oil levels or contamination may cause rebound issues. If necessary, service the damper.
- Check for air leaks. If the shock is losing air pressure, it may not function properly. Re-seat the air valve and inspect for leaks.
Issue: Sag Not Properly Set
If you can’t achieve the recommended sag:
- Check air pressure. The shock may need more or less air to reach the correct sag. Use a shock pump to adjust the pressure.
- Verify the shock size and stroke. Ensure that the Mara Pro Trunnion shock is the right size and stroke length for your bike frame.
Issue: Noisy Shock
If your shock is making unusual noises during compression or rebound:
- Inspect the seals. Worn or damaged seals can cause friction and noise. Replace seals as necessary.
- Lubricate the shock. Lack of lubrication can lead to squeaks or grinding noises. Apply suspension oil to the shock shaft and moving parts.
Compatibility with Other Drivetrain Components
The Mara Pro Trunnion rear shock is compatible with most modern mountain bike frames that feature a trunnion mount. It is important to check that the shock’s stroke length and mounting hardware are suitable for your frame. Some riders may need to purchase additional adapters or hardware to ensure compatibility with their specific frame and linkage system.
Shock Mount Compatibility
Make sure your bike’s frame is equipped with a trunnion-style mount before purchasing the Mara Pro shock. The shock’s eye-to-eye length and stroke should match the manufacturer’s recommendations for your bike frame. Incorrect sizing may result in improper shock performance or damage to the frame.
Customization and Optimization for Better Performance
To achieve the best performance from your Mara Pro Trunnion rear shock, customization is key. Here are a few ways you can optimize the shock for different riding conditions:
Adjusting for Terrain
- For aggressive downhill riding, increase compression to keep the shock from bottoming out and to maintain control.
- For cross-country or endurance riding, reduce compression for a more plush feel and better traction on rough terrain.
Tune for Riding Style
- For lighter riders, consider reducing the air pressure slightly for a more responsive shock.
- For heavier riders, increase the air pressure to prevent bottoming out and maintain stability.
Regularly assess your riding conditions and adjust the shock’s settings as needed to keep it performing at its peak [paid link].
