The Manitou Mara Inline Trunnion [paid link] Rear Shock is a high-performance suspension component designed for riders seeking precision, control, and durability. Over time, like all suspension parts, it requires regular maintenance to ensure optimal performance and longevity. This guide will cover everything from installation and adjustment to troubleshooting common issues, helping you get the most out of your rear shock.
Installation of the Mara Inline Trunnion Rear Shock
Preparation Before Installation
Before beginning the installation of your Mara Inline Trunnion [paid link] Rear Shock, it’s important to prepare the bike and tools needed for a smooth process. Make sure to clean the shock mounts and the area surrounding the rear shock to avoid introducing dirt into the suspension system.
Step-by-Step Installation
- Remove the Old Shock:
- Use a wrench to detach the mounting bolts that secure the existing shock.
- Be careful when removing the shock from its mounts to avoid damaging the surrounding frame.
- Install the Mara Inline [paid link] Trunnion Rear Shock:
- Position the shock in the frame, aligning the trunnion mounting holes with those on the frame.
- Ensure the shock is oriented correctly, with the damper side facing outward.
- Attach the mounting bolts, tightening them securely but not overtightening, as this can damage the shock bushings or frame.
- Torque Specifications:
- Use a torque wrench [paid link] to tighten the bolts according to the manufacturer’s recommended torque settings (usually specified in the shock’s manual). This ensures the shock is mounted securely without risking damage to the frame or shock.
- Check for Proper Mounting:
- After securing the shock, visually inspect the installation to ensure the shock is mounted properly. There should be no lateral movement, and the bolts should be flush with the frame.
Adjusting the Mara Inline Trunnion Rear Shock
Proper adjustment of the Mara Inline [paid link] Trunnion Rear Shock is essential for maximizing comfort and performance. The shock is equipped with various features such as rebound damping and compression settings that need to be customized based on the rider’s weight, riding style, and terrain.
Rebound Damping Adjustment
The rebound damping controls how quickly the shock returns to its original position after compression. Adjusting the rebound damping can fine-tune the shock’s response to different riding conditions.
- Turn the rebound knob clockwise to increase damping, which slows down the rebound.
- Turn the knob counterclockwise to decrease damping, allowing the shock to rebound faster.
Make small adjustments and test the shock on the trail. Too much rebound damping can make the shock feel sluggish, while too little can result in excessive bouncing.
Compression Damping Adjustment
The compression damping affects how the shock behaves under load, such as when riding over rough terrain or hitting bumps.
- Adjust the low-speed compression by turning the dial to increase or decrease resistance when the shock compresses slowly.
- High-speed compression is adjusted separately, controlling how the shock reacts to sharp, fast impacts. Fine-tuning this helps optimize comfort and control on technical trails.
Troubleshooting Common Issues with the Mara Inline Trunnion Rear Shock
Even with regular maintenance, issues may arise with the Mara Inline Trunnion Rear Shock. The following are common problems and their solutions.
1. Shock Losing Air Pressure
If you notice that the shock is losing air pressure, it could be a result of a damaged air seal or an improperly closed air valve.
- Solution: Inspect the air valve for leaks and ensure that the valve is tightly closed. If the air pressure loss continues, the air seals may need to be replaced, and the shock should be serviced by a professional.
2. Unresponsive Compression
If the shock feels too soft or unresponsive when hitting rough terrain, it may be due to incorrect compression damping settings or low air pressure.
- Solution: Check the compression settings and adjust accordingly. If the problem persists, check the shock’s air pressure and adjust it based on the manufacturer’s recommendations.
3. Noisy Shock
Noise from the shock is often caused by a lack of lubrication or contamination in the shock’s internal parts.
- Solution: Clean the shock’s external parts, especially the air sleeve and the shock body. Reapply lubricating oil to the necessary parts as recommended in the user manual. If the noise continues, it may be necessary to open the shock and inspect the internal components for damage or wear.
Customization and Optimization for Better Performance
To fully optimize the performance of your Mara Inline Trunnion Rear Shock, consider making adjustments based on your specific riding conditions and preferences.
Tuning for Weight and Riding Style
Adjust the shock’s air pressure and damping settings according to your body weight and the type of terrain you ride on. Lighter riders may need to decrease air pressure to get a more responsive shock, while heavier riders will likely need to increase pressure for better support. Similarly, riders who frequently tackle technical descents might prefer firmer compression settings to reduce bottoming out.
Fine-Tuning for Different Trail Conditions
- For smoother trails: Opt for a lower rebound damping setting and softer compression damping to absorb smaller impacts while maintaining a comfortable ride.
- For rougher, technical terrain: Increase compression damping to prevent excessive shock movement and increase rebound damping to control faster return after impacts.
Comparison with Similar Models
When comparing the Mara Inline Trunnion Rear Shock to other models, it is essential to focus on the shock’s unique features. The Mara Inline Trunnion is known for its robust performance, adjustability, and high level of customization.
Compared to the Fox Float X2
While the Fox Float X2 is a popular option for high-performance rear shocks, the Mara Inline Trunnion often stands out due to its more affordable price point and smoother performance on lighter bikes. The Fox Float X2, on the other hand, offers slightly more tuning options for professional riders, but the Mara Inline Trunnion is often a better fit for intermediate riders seeking reliability and ease of maintenance.
Compared to the RockShox Super Deluxe
The RockShox Super Deluxe offers a solid, user-friendly design, but the Mara Inline Trunnion typically provides a more responsive shock experience with greater ease in fine-tuning compression settings. The RockShox model is heavier and may not be as agile as the Mara Inline Trunnion on lighter, performance-oriented bikes.
Compatibility with Other Drivetrain Components
The Mara Inline Trunnion Rear Shock is designed to work with a wide range of bike frames, especially those that utilize trunnion-style mounts. However, ensuring compatibility with other drivetrain components is crucial to avoid performance issues.
Frame Compatibility
Check the frame’s specifications to ensure it supports a trunnion-mounted shock. The shock’s eye-to-eye length and stroke must also match the frame’s requirements. Installing a shock that is incompatible with your frame may lead to poor performance or damage.
Suspension Fork Compatibility
While the Mara Inline Trunnion Rear Shock is independent of the front suspension fork, it’s important to consider the balance between the rear shock and front fork. Ensure that the fork has similar travel and damping performance to maintain a smooth and consistent ride.
Regularly maintaining your Mara Inline Trunnion Rear Shock and making the necessary adjustments can ensure long-term performance and comfort. By following the steps outlined above, you can keep your shock in top condition and optimize your riding experience.
