Key Features of the Mara Pro Trunnion Rear Shock
The Mara Pro [paid link] Trunnion Rear Shock stands out in the crowded suspension market for its combination of advanced technology, robust build, and precise adjustment options. Below are some of the standout features that make it an ideal choice for trail and enduro riders:
1. Trunnion Mount Design
The Mara Pro [paid link] uses a trunnion mount system, which is more compact and provides better responsiveness than traditional eyelet mounts. The trunnion design offers a more progressive suspension feel, making it well-suited for aggressive riding styles. It also ensures a more direct transfer of energy between the frame and the shock.
2. Adjustable Air Spring
The air spring in the Mara Pro Trunnion is fully adjustable, allowing riders to fine-tune the shock for their weight, riding style, and terrain. The positive and negative air chambers are independently adjustable, giving you the flexibility to dial in the shock for a perfect balance of plushness and support.
3. Advanced Damping System
The shock features Manitou’s MC2 (Multiple Control Compression) damping system, which allows for easy adjustment of both low and high-speed compression. This provides greater customization for varying trail conditions, enabling riders to adapt the shock’s response to different terrain features.
4. Enduro-Level Durability
With a sturdy, hard-anodized aluminum body, the Mara Pro is built to withstand the rigors of enduro and aggressive trail riding. It is designed for long-lasting performance even in harsh conditions, offering superior resistance to wear and tear, dirt, and moisture.
5. High-Performance Seals
The Mara Pro comes equipped with high-quality seals that ensure smooth, consistent performance over long periods. These seals help reduce friction, which translates to improved suspension performance and a more comfortable ride.
6. Low-Speed and High-Speed Compression Adjustments
The Mara Pro allows for separate low-speed and high-speed compression adjustments, providing fine-tuning control to match a wide range of trail conditions. This feature enables riders to optimize the shock’s behavior when riding over smaller bumps or during aggressive impacts.
Installation of the Mara Pro Trunnion Rear Shock
Installing the Mara Pro Trunnion Rear Shock is a straightforward process, but it requires some technical expertise and proper tools to ensure optimal performance and safety. Follow these steps for installation:
Tools Required:
- Torque wrench [paid link]
- 5mm and 6mm Allen wrenches [paid link]
- 8mm socket wrench
- Grease
- Rags or paper towels
- Shock pump
Steps for Installation:
- Prepare the Frame: Clean the rear triangle of the frame to ensure there is no dirt or debris that could interfere with the installation process.
- Lubricate Mounting Hardware: Apply a small amount of grease to the trunnion mount and hardware before installation to prevent corrosion and facilitate smoother movement.
- Align the Shock: Carefully align the shock with the frame’s trunnion mount. The shock’s eyelets should fit into the mounting points on the frame without forcing or bending.
- Attach the Shock: Use the appropriate Allen wrenches [paid link] and socket wrench to securely fasten the bolts to the frame. Follow the manufacturer’s recommended torque settings to prevent over-tightening.
- Check for Movement: After installation, ensure the shock moves smoothly and there is no binding when the rear suspension is compressed and extended.
- Set the Sag: Use a shock pump to set the sag to the recommended setting based on your weight and riding style.
- Double Check: Before heading out for a ride, double-check all bolts for tightness and ensure there are no signs of leaks around the shock seals.
Maintenance of the Mara Pro Trunnion Rear Shock
Routine maintenance is essential to ensure your Mara Pro Trunnion Rear Shock continues to perform at its best. Here are some key maintenance tasks to keep in mind:
1. Regular Cleaning
After every ride, it’s essential to clean the shock to prevent dirt and grime from accumulating. Use a soft cloth to wipe down the shock body and avoid using harsh chemicals that could damage the seals.
2. Check Air Pressure
The air pressure in the shock needs to be checked regularly. Use a shock pump to ensure the air spring is set to the correct pressure. Low air pressure can affect the shock’s responsiveness, while too much pressure can lead to a harsh ride and reduced comfort.
3. Inspect for Leaks
Check the shock seals periodically for any signs of oil leakage. Leaking seals can indicate a need for servicing or replacement. If you notice oil buildup around the shock’s body or mounting points, it’s time to service the shock.
4. Servicing the Shock
Manitou recommends servicing the Mara Pro Trunnion Rear Shock at least once a year, or more frequently depending on usage and trail conditions. This may involve replacing seals, changing the oil, and recharging the air spring. Professional servicing is advised to maintain optimal performance.
Troubleshooting Common Setup Issues
If you’re experiencing issues with your Mara Pro Trunnion Rear Shock, here are some common problems and solutions:
1. Lack of Rebound
If the rebound feels sluggish or inconsistent, check the rebound adjustment dial to ensure it’s set to the correct position. If the problem persists, inspect the shock for any internal damage or wear that might require professional servicing.
2. Excessive Bottoming Out
If you’re experiencing frequent bottoming out, it may be due to insufficient air pressure or an incorrect sag setting. Double-check the air pressure and adjust it according to your weight and riding style. Increasing the compression setting may also help prevent bottoming out.
3. Unusual Noises
If you hear knocking or squeaking noises, check if the shock is properly mounted and that all bolts are tightened to the correct torque. Noises can also indicate that the shock seals may need replacing or that dirt has accumulated in the shock’s internals.
Customization and Optimization for Better Performance
The Mara Pro Trunnion Rear Shock offers a range of customizable options to suit various riding preferences and conditions. Here are some tips for optimizing the shock’s performance:
1. Fine-Tune Compression Settings
The shock’s high-speed and low-speed compression adjustments allow you to tailor the shock’s response based on trail conditions. For smoother terrain, you may want to reduce compression for a more plush ride. For aggressive, rocky trails, increasing the compression can help prevent excessive shock movement.
2. Rebound Adjustment
The Mara Pro features a rebound adjustment to control how quickly the shock returns after compression. Slower rebound is better for rougher terrain, as it helps maintain control, while faster rebound settings are ideal for smoother, faster rides.
3. Set the Right Sag
Ensuring the correct sag is crucial for maximizing comfort and performance. A general rule of thumb is to set the sag to around 25-30% of the total shock stroke, but this can vary based on rider weight and preferences.
Compatibility with Other Drivetrain Components
The Mara Pro Trunnion Rear Shock is compatible with a wide range of mountain bike frames that support trunnion-mounted shocks. However, it’s important to check the specifications of your frame before installation to ensure proper fitment. The shock’s performance is also influenced by other components in your drivetrain, such as the rear suspension linkage and the overall geometry of the bike. For the best results, it’s recommended to pair the Mara Pro with a frame designed for enduro or aggressive trail riding.
