Tools Required

• Manitou shock pump (compatible with the Mara Pro)
• 5mm and 6mm Allen wrenches [paid link]
• T20 Torx driver
• Torque wrench [paid link] (for accurate bolt tightening)
• A clean, flat work surface
• Small screwdriver (for air valve adjustments)
• Rags and cleaning solution (for maintenance)

Installation of the Mara Pro Rear Shock

Installing the Mara Pro rear shock requires attention to detail and the right set of tools to ensure proper setup. Here are the steps to follow:

1. Remove the old shock (if replacing an existing one): Use a 5mm Allen wrench [paid link] to remove the bolts securing the shock to the frame.
2. Align the shock mount: Place the Mara Pro shock into the frame’s shock mount, ensuring the eyelet is aligned properly with the frame’s pivot points.
3. Install the mounting bolts: Insert the bolts through the frame and the shock eyelet, securing them with a 5mm or 6mm Allen wrench [paid link]. Tighten the bolts to the manufacturer’s recommended torque specifications, usually around 30-35 Nm.
4. Check the shock’s movement: Before moving to the next step, compress the shock by hand to ensure it moves freely without any binding.

Adjusting the Mara Pro Rear Shock

The Mara Pro rear shock offers several adjustment features, allowing you to fine-tune its performance based on your weight, riding style, and terrain. Here’s how to adjust the various settings:

1. Air Pressure Setup

Adjusting the air pressure is essential for achieving the correct sag, which determines how much the shock compresses under your weight.

• Measure your sag: To set the correct air pressure, use a shock pump to inflate the Mara Pro to a recommended pressure based on your body weight. You can find the ideal air pressure range in the shock’s manual or use online calculators for an estimate. The target is typically around 25-30% sag, meaning the shock should compress by 25-30% of its total travel when you’re on the bike.
• Fine-tune the pressure: After setting the initial air pressure, sit on the bike and check the shock’s compression. If the shock compresses too much or not enough, adjust the air pressure by adding or releasing air in small increments until the sag is correct.

2. Rebound Adjustment

The rebound control adjusts how quickly the shock returns to its original position after compression.

• Locate the rebound dial: The Mara Pro’s rebound adjuster is typically located on the bottom of the shock.
• Adjust for ride style: Turn the dial to increase or decrease rebound speed. A slower rebound (clockwise) is ideal for rougher terrains where you want more control over the shock’s return. A faster rebound (counterclockwise) works well on smoother trails, allowing the shock to return quicker and keep the wheel in contact with the ground.

3. Compression Adjustment

The compression setting adjusts how the shock responds to impacts and terrain variations.

• Open or closed setting: The Mara Pro features adjustable low-speed compression. Use the knob to change the compression damping, allowing for a more responsive ride or more control when tackling technical descents.
• Tune for your needs: For smoother trails or climbs, you may prefer a more open compression setting, allowing the shock to respond [paid link] quickly to small bumps. For rough, downhill sections, a more closed compression setting will prevent the shock from bottoming out and provide better stability.

Maintenance of the Mara Pro Rear Shock

Regular maintenance ensures optimal performance and longevity of your Mara Pro rear shock. Here’s how to keep it in top condition:

• Clean the shock: After each ride, wipe down the shock body with a clean rag and mild cleaning solution to remove dirt, mud, and debris. Pay special attention to the seals and the air valve area.
• Check for leaks: Inspect the air valve for leaks. If you notice a loss of air pressure, ensure the valve is fully tightened and sealed. If the issue persists, you may need to replace the valve core.
• Lubricate the shock’s mounting hardware: Apply a small amount of grease to the shock’s mounting bolts and eyelets to prevent seizing and wear.

Troubleshooting Common Mara Pro Rear Shock Issues

While the Mara Pro is a reliable and high-performing shock, issues can sometimes arise. Here’s how to troubleshoot common problems:

1. Shock Bottoming Out

If the shock is bottoming out frequently, it may be under-inflated or set to too low a compression damping.

• Solution: Increase the air pressure or adjust the compression damping to a firmer setting. Ensure you’re achieving the correct sag (25-30%).

2. Excessive Rebound

If the shock feels too bouncy or doesn’t absorb impacts efficiently, the rebound setting may be too fast.

• Solution: Slow down the rebound by turning the adjuster clockwise to allow the shock more time to return to its original position.

3. Loss of Air Pressure

If the Mara Pro is losing air over time, there may be a problem with the air valve or internal seals.

• Solution: Check the valve for leaks and replace the valve core if necessary. If the problem persists, it might be time to have the shock serviced.

Customization and Optimization

To get the most from your Mara Pro rear shock, consider the following tips for optimizing performance:

• Tailor your air pressure: Based on your riding style and terrain, you may prefer a slightly higher or lower sag percentage. Experiment with small adjustments to find your perfect setup.
• Customize damping settings: Play with the low-speed compression and rebound adjustments to tune the shock for your riding conditions. For aggressive downhill riders, a stiffer compression setting will help absorb big hits, while lighter trail riders may prefer more rebound and an open compression setting for maximum comfort and efficiency.
• Suspension linkage tuning: If your bike frame allows it, adjusting the suspension linkage can also impact how the Mara Pro behaves. Check your frame’s specifications for recommended setups that optimize the rear shock’s performance.

Compatibility with Other Drivetrain Components

The Mara Pro rear shock is compatible with most modern mountain bikes and trail bikes, provided the frame has a standard shock mount size. However, it is important to check the following for full compatibility:

• Shock Length: Verify that the Mara Pro’s shock length (eye-to-eye) matches the specifications of your bike’s frame.
• Mounting Standard: Ensure that your bike’s rear triangle can accommodate the shock’s mount type (standard, metric, or other proprietary systems).
• Travel: The shock’s travel must align with your bike’s geometry. Check the shock’s travel range to ensure compatibility with your frame’s intended performance.

Conclusion

With proper installation, regular maintenance, and fine-tuning, your Manitou Mara Pro rear shock can significantly enhance your ride. By adjusting air pressure, rebound, and compression settings, as well as maintaining the shock’s cleanliness and performance, you’ll ensure optimal function for any type of terrain. Troubleshooting issues promptly and making the right customizations will allow you to maximize the potential of this premium rear shock.
