The Mara Inline [paid link] rear shock from Manitou is a high-performance suspension component designed for riders who demand precision and durability. Regular maintenance is essential to keep it in peak [paid link] condition and ensure a smooth and efficient ride. While servicing the Mara Inline [paid link] may seem like a daunting task, it is entirely possible to perform a basic service on your own with the right tools and knowledge.

This guide will walk you through the process of servicing your Mara Inline rear shock, including installation, adjustment, maintenance, troubleshooting, and optimization. By following the steps carefully, you’ll be able to maintain your shock, troubleshoot common issues, and ensure optimal performance without needing a mechanic.

Tools Required

• 8mm Allen wrench [paid link]
• 5mm Allen wrench [paid link]
• Shock pump
• Torque wrench [paid link]
• Suspension oil (specific to the Mara Inline model)
• Cleaning cloths
• O-ring grease
• A stand or secure platform to hold the bike

Installation of the Mara Inline Rear Shock

Installing the Mara Inline rear shock onto your bike is a straightforward process, but it requires attention to detail to ensure proper fit and function. Follow these steps to install the shock correctly:

1. Prepare the Bike: Secure the bike in a stand or on a stable surface to make installation easier.
2. Remove the Old Shock (if applicable): If you are replacing an old shock, use the 8mm and 5mm Allen wrenches [paid link] to remove it from the rear triangle of the bike.
3. Insert the New Mara Inline Shock: Slide the new Mara Inline shock into place, ensuring that the shock’s eyelets align properly with the rear triangle mounts.
4. Secure the Shock: Tighten the bolts with the appropriate torque specification (usually around 8-10 Nm) to secure the shock in place. Use the torque wrench [paid link] to avoid over-tightening.
5. Attach the Air Canister: Attach the air canister to the shock body. Ensure the seals are properly aligned to prevent any air leaks.

After installation, you may need to adjust the air pressure, which is covered later in this guide.

Adjustment of the Mara Inline Rear Shock

To ensure that the Mara Inline rear shock performs at its best, you’ll need to make some key adjustments. This includes adjusting the air pressure, rebound, and compression settings to suit your riding style and the terrain.

Adjusting Air Pressure

1. Check Manufacturer’s Recommendations: Begin by consulting the Manitou Mara Inline air pressure chart. The correct air pressure depends on the rider’s weight and the type of terrain.
2. Inflate the Shock: Use a shock pump to adjust the air pressure. Attach the pump to the Schrader valve and gradually add air. Be cautious not to overinflate; the shock should feel firm but with some give.
3. Test and Fine-Tune: After adding air, take the bike for a short ride to test the shock. If necessary, adjust the pressure up or down by small increments until you find the ideal balance between comfort and control.

Rebound Adjustment

Rebound controls how quickly the shock returns to its normal position after compression. To adjust the rebound:

1. Locate the Rebound Dial: The Mara Inline has a rebound dial located near the shock’s reservoir.
2. Turn the Dial: Turn the dial clockwise to slow the rebound, or counterclockwise to speed it up. Begin by setting it to the middle and adjust based on your preference. A slower rebound may be beneficial for rough terrain, while a quicker rebound works better for smoother trails.

Compression Adjustment

Compression affects how the shock responds to impacts and rough terrain. The Mara Inline features adjustable low-speed compression, which allows fine-tuning for different riding conditions.

1. Locate the Compression Dial: The compression dial is typically located near the top of the shock body.
2. Adjust the Setting: Turn the dial to adjust the compression. A stiffer setting (clockwise) is suitable for aggressive riders or rough terrain, while a softer setting (counterclockwise) offers more comfort on smoother trails.

Maintenance of the Mara Inline Rear Shock

Routine maintenance is vital for ensuring that your Mara Inline rear shock performs at its peak [paid link]. Here are the steps for basic servicing and maintenance:

Cleaning and Inspection

1. Clean the Shock Regularly: After every ride, wipe down the shock with a clean cloth to remove dirt and debris. Pay close attention to the seals and air canister, as dirt buildup can lead to premature wear.
2. Inspect the Seals: Check the seals for any signs of damage or wear. Damaged seals can lead to air loss and fluid leakage, affecting performance.

Lubing the Shock

To keep the shock’s seals and moving parts functioning smoothly, apply a small amount of suspension-specific lubricant to the seals and shaft. This will help reduce friction and prevent wear.

1. Lubricate the Shaft: Apply a light coat of suspension oil to the shock shaft, ensuring that it is evenly distributed.
2. Lubricate the Eyelets: Apply a small amount of O-ring grease to the shock’s eyelets to ensure smooth motion and prevent creaking.

Air Canister Service

Manitou recommends servicing the air canister annually to maintain optimal performance. To service the air canister, remove it from the shock body, clean it, and replace the air seals. This can be done with basic tools, but if you’re unsure about the process, consider having it serviced by a professional.

Troubleshooting Common Issues

Even with regular maintenance, issues may arise with your Mara Inline rear shock. Here are some common problems and how to resolve them:

Problem 1: Loss of Air Pressure

If your Mara Inline rear shock is losing air pressure, it may be due to a small leak in the air canister or the Schrader valve.

• Solution: Inspect the Schrader valve and tighten it if necessary. If the air canister is leaking, you may need to replace the seals or send the shock for professional service.

Problem 2: Too Much Rebound

If the shock is bouncing back too quickly after compression, it could be due to a rebound setting that is too fast.

• Solution: Adjust the rebound dial to slow the rebound rate. Turn it clockwise to reduce the speed.

Problem 3: Bottoming Out

If the shock bottoms out too easily on rough terrain, it could be due to insufficient air pressure or low compression settings.

• Solution: Increase the air pressure or stiffen the compression setting to prevent bottoming out.

Customization and Optimization for Better Performance

To get the most out of your Mara Inline rear shock, consider customizing the settings based on your riding style and terrain. Here are some tips for optimizing the shock:

1. Adjust Air Pressure for Weight: Fine-tuning the air pressure for your weight will help you achieve the right balance between comfort and performance. Aim for a setting that gives you about 20-30% sag when you’re sitting on the bike.
2. Optimize Rebound for Terrain: If you primarily ride on rough trails, slow down the rebound to absorb more of the impacts. For smoother trails, speed it up for a more responsive ride.
3. Fine-Tune Compression: For aggressive riding on technical trails, increase the compression setting to reduce harsh bottoming out. For cross-country or smoother trails, a softer setting will provide a more plush ride.

Compatibility with Other Drivetrain Components

The Mara Inline rear shock is compatible with most modern mountain bike frames designed to accept a rear shock. However, it is crucial to verify the shock size and mounting hardware to ensure compatibility with your frame. The shock features both standard and metric mount options, so check your frame’s specifications to ensure a proper fit.

Additionally, while the Mara Inline rear shock is designed to work seamlessly with many drivetrain components, ensure that your rear suspension setup is in harmony with the rest of your bike’s suspension, including the fork and linkage system, for balanced performance.
