The Marzocchi Bomber Air [paid link] Rear Shock is a high-performance suspension component designed for aggressive mountain biking and enduro riders. Known for its durability, tunability, and precision, this rear shock excels in providing a smooth, controlled ride across rough terrains. In this detailed guide, we will cover everything from installation and maintenance to troubleshooting and optimization, focusing on how to get the most out of your Bomber Air [paid link] rear shock.
Installation of the Bomber Air Rear Shock
Installing the Bomber Air Rear Shock requires attention to detail and a solid understanding of suspension setup. A correct installation ensures peak [paid link] performance and longevity of the component. Here’s a step-by-step guide to install the Bomber Air Rear Shock:
Tools Required
- 8mm Hex wrench
- Torque wrench [paid link]
- Shock pump
- Rags or cleaning cloths
- Grease (optional)
Step-by-Step Installation
- Remove the Old Shock: Use the 8mm hex wrench to remove the bolts securing the old rear shock to the bike frame. Carefully detach the shock.
- Prepare the Bomber Air Shock: If you’re replacing an old shock, ensure the Bomber Air Shock is free of dust and contaminants. Apply a small amount of grease to the mounting hardware if recommended by the manufacturer.
- Align the Shock: Position the Bomber Air Shock in the rear shock mounts of the bike frame. Ensure it is properly aligned with the mounting holes.
- Secure the Mounting Bolts: Insert the bolts and tighten them to the manufacturer’s specified torque using a torque wrench [paid link]. Proper torque ensures the shock stays securely in place during rides.
- Inflate the Shock: Use a shock pump to set the correct air pressure based on the rider’s weight. This is crucial for achieving the desired ride characteristics.
- Check for Proper Fit: After installation, compress the shock to ensure smooth movement without any binding. If the shock moves freely, it’s properly installed.
Adjustments and Tuning for Performance
The Bomber Air rear shock features various adjustment options to fine-tune the performance based on rider preferences and trail conditions. Key settings include:
- Rebound Damping: Controls the speed at which the shock returns to its extended position after compression. Adjust the rebound knob to suit the rider’s style and the terrain. Faster rebound is ideal for smoother trails, while slower rebound helps on rougher, more technical trails.
- Compression Damping: The compression knob adjusts how the shock responds to hits and impacts. Increasing compression damping provides more support, ideal for aggressive riders or downhill sections. Decreasing it allows for a more plush feel on rough trails.
- Air Pressure: The Bomber Air is an air-sprung shock, meaning its performance heavily depends on air pressure. Adjust the air pressure based on the rider’s weight and desired sag, typically between 25-30% for most riders. Use a shock pump to make precise adjustments.
Fine-Tuning Tips
- Experiment with settings: Start with factory settings and gradually fine-tune each adjustment based on the trail and riding style.
- Record adjustments: Keeping track of changes allows you to return to a proven setting if you experiment too much.
Maintenance of the Bomber Air Rear Shock
Regular maintenance is essential for ensuring the longevity and performance of your Bomber Air Rear Shock. Proper maintenance will prevent wear, improve ride quality, and avoid costly repairs.
Basic Maintenance Steps
- Clean the Shock Regularly: After every ride, wipe down the shock with a clean cloth to remove dirt and debris. This prevents contaminants from entering the seals and damaging the internal components.
- Check Air Pressure: Air pressure in the shock can fluctuate with temperature changes. Always check the air pressure before each ride and adjust it if necessary.
- Inspect the Seals: Regularly check the seals for any signs of wear or damage. If you notice any leaks or excessive oil, it’s time to replace the seals.
Full Service Intervals
Marzocchi recommends servicing the Bomber Air Rear Shock every 50-100 hours of riding, depending on conditions. A full service includes:
- Disassembly: Removal of the shock from the bike.
- Cleaning: Thorough cleaning of internal parts.
- Lubrication: Re-greasing and re-oiling of internal components.
- Seal Replacement: Inspecting and replacing any worn seals.
A suspension service center or a qualified mechanic can perform this task if you’re not comfortable handling it yourself.
Troubleshooting Common Setup Issues
While the Bomber Air Rear Shock is built to handle tough conditions, riders may encounter a few common issues during setup or while riding. Here are some potential issues and solutions:
1. Shock Bottoming Out
- Possible Cause: The air pressure might be too low, or the compression damping might be set too soft.
- Solution: Increase the air pressure and adjust the compression damping to prevent excessive bottoming out during big hits.
2. Shock Not Returning Quickly Enough
- Possible Cause: The rebound damping may be set too low (slow rebound).
- Solution: Increase the rebound damping to allow the shock to return to its extended position faster.
3. Unusual Noises from the Shock
- Possible Cause: Dirt or debris in the shock body or worn seals.
- Solution: Clean the shock thoroughly and inspect the seals. Replace any damaged seals and re-lubricate the shock if necessary.
4. Air Leaks
- Possible Cause: Faulty seals or incorrect installation of the shock.
- Solution: Check the seals for damage or wear. If necessary, perform a full service to replace seals and ensure the shock is properly installed.
Customization and Optimization for Better Performance
Customizing the Bomber Air Rear Shock for your riding style and conditions can drastically improve its performance. Here are some tips to achieve optimal performance:
- Tuning Based on Terrain: For aggressive downhill or enduro riders, increase the compression damping to prevent excessive shock movement. For cross-country or lighter riding, you may want to decrease compression damping for a more supple, active feel.
- Adjusting for Rider Weight: Adjusting air pressure to match the rider’s weight is crucial for achieving the correct sag and suspension behavior. Riders who are heavier or lighter than average may need to adjust air pressure accordingly to achieve the ideal sag percentage (25-30%).
- Dual Air or Single Air Chambers: If you prefer a more supportive ride, the Bomber Air offers a dual-chamber design, providing better customization for more aggressive riders. For a smoother, more forgiving ride, use the single air chamber configuration.
Compatibility with Other Drivetrain Components
The Marzocchi Bomber Air Rear Shock is compatible with a wide range of mountain bikes, but compatibility with other drivetrain components depends on the bike frame’s specifications. Typically, the Bomber Air shock will pair well with modern mountain bikes that use standard 200x57mm or 210x50mm shock sizes.
When pairing with other drivetrain components, such as suspension forks or front shock systems, ensure that the rear shock’s characteristics align with those of the front suspension for optimal balance. For instance, if you’re using a coil-sprung front fork, it may be wise to adjust the Bomber Air’s air spring settings to match the plushness and performance of the front fork. Similarly, if you’re using a more aggressive front fork, the Bomber Air may need stiffer damping or higher air pressure.
Conclusion
The Marzocchi Bomber Air Rear Shock stands out for its versatility, durability, and performance across various mountain biking disciplines. With careful installation, regular maintenance, and thoughtful tuning, this shock can provide excellent performance for riders who demand the best in both comfort and control. Whether you’re riding cross-country trails, tackling enduro tracks, or enjoying aggressive downhill runs, the Bomber Air offers the reliability and adjustability you need for a smooth and controlled ride.
