Tools Required

Before beginning any installation, adjustment, or maintenance on the Bomber Air rear shock, ensure you have the following tools available:

• Shock pump (for air pressure adjustment)
• 5mm Allen wrench [paid link]
• Torque wrench [paid link]
• Suspension fluid (if required for servicing)
• Cleaning supplies (cloth, degreaser, etc.)
• Replacement seals (if needed)
• Safety gloves (optional)
• Compression and rebound setting tools (if applicable)

Installation of the Bomber Air Rear Shock

Installing the Bomber Air rear shock requires a few essential steps to ensure proper fitment and secure mounting. This process is straightforward for most riders with basic bike mechanics experience.

1. Remove the Old Shock (if applicable)
   If you’re replacing an existing rear shock, start by removing it from the bike frame. Use the 5mm Allen wrench [paid link] to remove the mounting bolts securing the shock in place. Be sure to keep track of any washers or spacers that may be used for alignment.
2. Prepare the Bomber Air Shock
   Before installation, ensure the Bomber Air shock is properly inflated to the recommended air pressure. Use a shock pump to adjust the pressure according to your weight and riding style.
3. Align the Shock
   Position the Bomber Air shock between the frame’s shock mounts. Check that the shock’s eyelets align with the mounting points on the frame. You may need to adjust the positioning slightly to ensure that the shock is properly aligned before tightening.
4. Secure the Shock
   Insert the mounting bolts through the shock’s eyelets and into the frame’s mounting points. Use the 5mm Allen wrench to tighten the bolts securely. Make sure not to overtighten, as this can damage the shock or the frame. If required, consult the bike frame manufacturer’s torque specifications.
5. Final Check
   After installation, check that the shock is securely mounted and there is no play or unwanted movement. Perform a quick test by compressing the shock to ensure smooth action.

Adjusting the Bomber Air Rear Shock

The Bomber Air rear shock provides several adjustable settings that help optimize the ride quality. These include air pressure, rebound, and compression settings.

Air Pressure Adjustment

The air pressure setting is the most crucial adjustment to customize the shock’s performance to your weight and riding style.

1. Determine the Correct Air Pressure
   The ideal air pressure for the Bomber Air rear shock is determined by your body weight. Marzocchi typically provides a chart with recommended pressures based on weight. However, you can fine-tune the air pressure depending on how firm or plush you prefer the shock to feel.
2. Inflate or Deflate the Shock
   Using a shock pump, inflate the shock to the recommended pressure. If the shock is too soft, it will bottom out too easily on bigger hits, while too much pressure will result in a harsh ride. Make small adjustments and test ride to find the optimal pressure for your needs.

Rebound Adjustment

The rebound adjustment controls how quickly the shock returns to its original position after compression. A slower rebound is useful for technical trails, while faster rebound is preferred for smoother terrain.

1. Locate the Rebound Knob
   The rebound adjustment knob is typically located at the bottom of the shock.
2. Set the Rebound Speed
   Start with the factory setting and adjust the rebound based on your preference. Turn the knob clockwise for slower rebound and counterclockwise for faster rebound. Perform test rides and make further adjustments as needed.

Compression Adjustment

The Bomber Air rear shock offers compression adjustment to help control how the shock responds to small and large impacts.

1. Locate the Compression Knob
   The compression adjustment is usually found on the top of the shock.
2. Adjust the Compression
   Turn the compression knob clockwise for a firmer ride, which is better for tackling technical sections, or counterclockwise for a softer, more forgiving feel on rough terrain.

Maintenance of the Bomber Air Rear Shock

Regular maintenance is essential to keep the Bomber Air rear shock functioning at its peak [paid link]. Proper care will extend its lifespan and maintain performance.

Cleaning the Shock

1. Remove Dirt and Debris
   After every ride, clean the shock by wiping it down with a damp cloth. Avoid using harsh chemicals, as these may damage the shock’s finish or seals.
2. Inspect for Damage
   Regularly inspect the shock’s stanchions and seals for any signs of damage, such as cuts, nicks, or tears. Replace damaged seals immediately to prevent air leaks and contamination.

Air Pressure Check

Ensure that the air pressure remains consistent, especially if the bike has been sitting for a while. Re-check air pressure before each ride and adjust as necessary.

Servicing the Shock

Marzocchi recommends servicing the Bomber Air rear shock every 50-100 hours of riding or once a year, whichever comes first. This includes cleaning, replacing seals, and checking the internal suspension fluid. Depending on the condition, you may choose to take the shock to a professional mechanic or service it yourself if you have the required tools and knowledge.

Troubleshooting Common Set-Up Issues

If you’re experiencing issues with your Bomber Air rear shock, here are some common problems and solutions:

Shock Bottoming Out

• Problem: The shock bottoms out on large hits, resulting in a harsh ride.
• Solution: Increase the air pressure in the shock to provide more support. If the problem persists, check the compression settings and adjust them to a firmer setting.

Lack of Support

• Problem: The shock feels too soft and doesn’t provide enough support.
• Solution: Increase the air pressure to ensure proper support. You may also need to adjust the rebound or compression settings to fine-tune the shock’s performance.

Noisy Shock

• Problem: The shock produces an unusual sound during compression or rebound.
• Solution: Check for any dirt or debris in the shock’s seals. Clean the shock thoroughly and apply lubrication if needed. If the noise persists, inspect the shock for internal issues that may require professional servicing.

Customization and Optimization for Better Performance

To maximize the performance of the Bomber Air rear shock, consider these customization tips:

• Adjust Air Pressure for Riding Style: If you prefer aggressive downhill riding, increase the air pressure for better bottom-out resistance. For cross-country or trail riding, reduce the air pressure for a more supple ride.
• Fine-Tune Compression Settings: Experiment with different compression settings to match the terrain you ride most often. A firmer compression is better for aggressive riders, while a softer setting offers more comfort on rough trails.
• Upgrade Seals or Internal Parts: If you’re aiming for the best performance, consider upgrading the seals or internal components to improve longevity and smoothness.

Compatibility with Other Drivetrain Components

The Bomber Air rear shock is designed to be compatible with most modern mountain bike frames, but it’s essential to check the specifications for compatibility with your bike’s geometry and suspension system. Ensure the shock’s eyelet size and mounting hardware match your frame, and consider the shock’s travel length in relation to the frame’s design.

Travel and Frame Geometry Compatibility

• The Bomber Air rear shock comes in various travel options. When selecting the correct shock, ensure that the travel length matches the intended geometry of your frame. A mismatch in travel length could result in suboptimal handling or suspension performance.

Integration with Other Suspension Components

• If you are running a dual suspension bike, consider how the Bomber Air shock integrates with your front suspension fork. Matching the characteristics of the front and rear suspension systems can significantly improve the overall ride quality and performance of your bike.

Conclusion

The Marzocchi Bomber Air rear shock is a high-performance suspension system that delivers exceptional performance, adjustability, and durability. Whether you’re installing, adjusting, maintaining, or optimizing your shock, following this comprehensive guide will help you maximize the potential of your Bomber Air shock. With regular maintenance and thoughtful adjustments, your shock will continue to perform at its best, enhancing your overall riding experience.
