DIY Maintenance Guide for Your Mara Pro Rear Shock

The Mara Pro [paid link] rear shock from Manitou is a high-performance shock designed to offer superior control, comfort, and durability for mountain bikers. However, like all suspension components, the Mara Pro [paid link] requires regular maintenance to keep it performing at its best. In this guide, we will cover everything from installation to troubleshooting and optimization of your Mara Pro rear shock. Whether you are a seasoned rider or a beginner, this guide will help you keep your Mara Pro rear shock in top condition.

Tools Required

Before you begin any maintenance tasks on the Mara Pro rear shock, make sure you have the following tools on hand:

  • Shock pump
  • 5mm and 6mm hex wrenches
  • Torque wrench [paid link]
  • 10mm open-end wrench
  • Oil drain pan
  • Manitou-specific suspension fluid (check your manual for the exact type)
  • Grease (preferably suspension-specific grease)
  • Clean rags
  • Isopropyl alcohol for cleaning
  • Piston band tool (for internal service)
  • Zip ties for securing cables (if applicable)

Installation of the Mara Pro Rear Shock

Installing the Mara Pro rear shock on your bike requires precision to ensure proper function and safety. Follow these steps carefully to avoid any issues down the road.

1. Remove the Old Shock

Before installing the new Mara Pro shock, remove your old rear shock by loosening the bolts on both the top and bottom shock mounts using a 5mm or 6mm hex wrench. Be sure to support the bike’s rear end while doing this, as removing the shock will cause the rear triangle to drop.

2. Prepare the New Mara Pro Shock

Before installing the new shock, inspect it for any signs of damage that may have occurred during shipping. Ensure that the shock is filled with the correct amount of air pressure according to the specifications in the Mara Pro’s manual.

3. Install the Shock

Position the shock in the rear triangle, aligning the shock mounts with the frame’s mounting points. Insert the bolts through the mounts and use a torque wrench [paid link] to tighten them according to the manufacturer’s specifications. Be sure not to overtighten the bolts, as this can cause damage to the frame or shock.

4. Set the Air Pressure

Using a shock pump, adjust the air pressure in the Mara Pro rear shock according to your body weight and preferred riding style. This will ensure optimal suspension performance. The recommended air pressure range is typically printed on the shock, but for more precise settings, refer to the Manitou manual.

5. Perform a Final Check

Once the shock is installed, double-check the bolts to ensure they are secure. Cycle the suspension by gently compressing and releasing it to ensure everything moves smoothly. If the shock is not compressing properly, recheck the air pressure or inspect for any internal damage.

Adjustment and Tuning of the Mara Pro Rear Shock

The Mara Pro rear shock offers several adjustment features to allow you to fine-tune the suspension for your riding preferences.

1. Rebound Damping

Rebound damping controls how quickly the shock returns to its original position after being compressed. Adjusting the rebound damping ensures your bike handles well on different terrains. Turn the rebound knob clockwise to slow down the rebound and counterclockwise to speed it up. Start with the factory settings and adjust from there based on the conditions you ride in.

2. Compression Damping

The Mara Pro shock allows you to adjust compression damping to control how much the shock compresses under force. This can be particularly useful when riding on rough or technical terrain. The compression knob on the shock will typically have settings for low, medium, and high compression. Experiment with these settings to find what works best for your riding style.

3. Volume Spacers

If you find that the shock is either too plush or too firm, you may want to experiment with volume spacers. These spacers adjust the shock’s air spring curve, providing more or less support in the initial stroke. Adding spacers increases bottom-out resistance, while removing them allows for a more plush feel. Follow the manufacturer’s guidelines on how to install or remove spacers.

Regular Maintenance for Your Mara Pro Rear Shock

To keep your Mara Pro rear shock in excellent condition, regular maintenance is essential. Manitou recommends servicing your shock every 50-100 hours of riding, depending on conditions and riding intensity.

1. Clean the Shock Regularly

After every ride, wipe down the shock with a clean rag to remove dirt, mud, and debris. This helps prevent contamination of the seals and reduces wear. Use isopropyl alcohol to clean the shock stanchion and ensure smooth movement.

2. Lubricate the Shock

Apply suspension-specific grease to the shock bushings to prevent wear and ensure smooth operation. Over time, the grease can break down, so it’s important to check the condition of the lubrication regularly.

3. Check for Leaks

Inspect the shock for any signs of oil or air leaks. If you notice any, it may be time to replace the seals or perform an internal service. Leaks can reduce the shock’s performance and cause further damage if left unchecked.

4. Perform Internal Service

If you’re comfortable with disassembling the shock, you can perform an internal service. This includes draining and replacing the shock fluid, inspecting the damper cartridge, and replacing worn seals. For an internal service, use a piston band tool to safely remove the damper from the shock body. Always follow the manufacturer’s instructions for servicing your shock.

Troubleshooting Common Mara Pro Rear Shock Issues

While the Mara Pro is a durable and reliable rear shock, occasional issues can arise. Here are some common problems and solutions.

1. Lack of Rebound or Slow Rebound

If the rebound is too slow or not working at all, the rebound adjuster may need to be re-set or replaced. Check the rebound knob to ensure it is turning correctly. If there is still an issue, internal servicing may be required to inspect the damper cartridge and fluid.

2. Sag or Insufficient Compression

If your shock seems to be sagging too much or not providing enough compression, it could indicate insufficient air pressure or an issue with the compression damping. First, check and adjust the air pressure according to your weight. If the problem persists, check the compression knob and inspect the shock internals for leaks or worn parts.

3. Noisy Shock

If your Mara Pro rear shock is making unusual noises, it could be due to dirt or debris in the shock bushings or seals. Clean and lubricate the shock regularly to prevent this. If the noise persists, inspect the internal components for damage.

Customization and Optimization for Better Performance

To optimize the Mara Pro rear shock for specific riding conditions, consider these tips:

  • Adjust Air Pressure: The Mara Pro offers great tunability through air pressure. Adjust the pressure based on your body weight and the terrain you ride. Lower pressures provide a softer, more compliant ride, while higher pressures offer firmer support.
  • Use Volume Spacers: If you ride rough terrain or need more control, adding volume spacers will increase the support on larger impacts, preventing bottom-out.
  • Tune Compression and Rebound: Dial in the compression and rebound settings to fit your riding style. Riders who prefer a more aggressive ride may want a firmer shock with higher compression and faster rebound.

Compatibility with Other Drivetrain Components

The Mara Pro rear shock is designed to be compatible with most modern mountain bike frames. However, it is important to verify the shock size and mount type to ensure proper fitment. The shock is typically available in various eye-to-eye and stroke lengths to match different frame geometries. Always check compatibility with your bike’s rear triangle before installation.

In conclusion, maintaining and optimizing the Manitou Mara Pro rear shock is essential for ensuring it continues to perform at its best. By following the steps outlined in this guide for installation, maintenance, and troubleshooting, you can keep your shock functioning smoothly and prolong its lifespan. Regular attention and proper adjustments will help you get the most out of your suspension system, providing a smoother, more controlled ride on any terrain.
