Air Rear Shock

Pre-Installation Preparations

Before installing the Bomber Air Rear Shock, it’s important to gather all the necessary tools and make sure your bike is properly prepared. Start by ensuring your bike frame is compatible with the Bomber Air shock. Check the eyelet size, shock length, and mount style to confirm the shock will fit your frame properly.

Tools Required

• 5mm Allen wrench [paid link]
• Torque wrench [paid link]
• Shock pump
• Shock mounting hardware (usually provided)
• Grease

Step-by-Step Installation Process

1. Remove the Old Shock: If you are replacing an old rear shock, start by removing it from the bike frame. Loosen the mounting bolts using a 5mm Allen wrench [paid link].
2. Prepare the Bomber Air Shock: Apply a thin layer of grease to the shock mounting hardware to ensure smooth installation and prevent creaking.
3. Mount the Bomber Air Shock: Position the shock on the bike frame, aligning the mounting holes. Secure the shock using the appropriate bolts, ensuring they are tightened to the manufacturer’s specified torque.
4. Check for Proper Alignment: Once the shock is installed, check the alignment of the shock eyelets. The shock should move smoothly without any binding.
5. Set Air Pressure: Use a shock pump to set the air pressure according to your rider weight and preferences. This will require fine-tuning to ensure proper sag and damping.
6. Test the Shock: After installation, check the shock’s compression and rebound settings. Perform a few test rides to verify the shock’s performance.

Adjustment and Maintenance of the Bomber Air Rear Shock

Air Pressure Adjustment

The Bomber Air features an air spring system that can be adjusted to match your riding style. Adjusting the air pressure is key to achieving the ideal sag, which impacts both comfort and control.

• Setting Air Pressure: Begin by using a shock pump to set the air pressure based on your weight. Check the manual for specific air pressure recommendations.
• Checking Sag: Sag is the amount the shock compresses under your weight. To achieve the proper sag, sit on your bike and check the shock’s stroke. Typically, a sag of 25-30% is ideal for most riders.

Damping Adjustments

The Bomber Air is equipped with high and low-speed compression and rebound damping adjustments. Fine-tuning these settings allows you to customize the shock’s performance to suit different terrains.

• Compression Damping: Adjust the compression to control how the shock responds to small bumps and impacts. Lower compression settings provide more comfort and sensitivity, while higher settings offer better stability on rough terrain.
• Rebound Damping: Rebound controls how quickly the shock returns after compression. Slower rebound damping is beneficial for rough terrain, preventing the shock from bouncing too quickly, while faster rebound damping suits smoother trails.

Regular Maintenance

Routine maintenance is essential to keep the Bomber Air rear shock in peak [paid link] condition. Marzocchi recommends servicing the shock every 50 hours of riding or once a year, whichever comes first.

• Cleaning: Clean the shock regularly with mild soap and water, making sure to remove any dirt and grime from the shock body and seals.
• Lubrication: Apply a small amount of lubrication to the shock’s stanchion and seals to reduce friction.
• Check for Leaks: Periodically check the air valve and seals for leaks. If you notice any loss of air pressure, inspect the seals for wear and replace them if necessary.

Troubleshooting Common Set-Up Issues

Loss of Air Pressure

If you notice that your shock is losing air pressure, it could be due to a damaged seal or valve. Start by inspecting the shock for any visible signs of wear. If no external damage is found, check the air valve for leaks or consider having the shock professionally serviced.

Lack of Rebound or Compression Control

If the shock isn’t responding properly to rebound or compression adjustments, it may be an issue with the damping circuit. Ensure the damping knobs are set correctly. If the problem persists, the shock may require servicing to clean or replace the internal components.

Too Much or Too Little Sag

If your sag is too high or too low, you may need to adjust the air pressure. If adjusting the air pressure doesn’t solve the problem, check the shock mounting to ensure it’s installed correctly, as incorrect mounting can affect the sag.

Customization and Optimization for Better Performance

Fine-Tuning the Air Pressure

For riders seeking to maximize comfort and performance, fine-tuning the air pressure is crucial. Experiment with different pressures to find the optimal balance between comfort and control. Remember, lighter air pressure provides a smoother ride but can make the shock feel less stable on aggressive terrain. On the other hand, higher air pressure increases stability but can reduce comfort.

Upgrading Components

While the Bomber Air Rear Shock is already a high-performance shock, some riders may choose to upgrade the shock’s components for even better performance. Consider swapping out the stock mounting hardware for lighter materials, such as titanium bolts, or adding volume spacers to modify the shock’s spring curve.

Optimizing Rebound and Compression

For enduro riders, setting the compression damping to be firmer on the descents and softer on the climbs can make a significant difference. Likewise, adjusting the rebound damping to match the terrain’s characteristics can help keep the bike stable and responsive.

Comparison with Similar Models

When comparing the Bomber Air to other rear shocks in the market, the key differences lie in its build quality, damping options, and ease of maintenance. Similar shocks like the Fox Float X2 and RockShox Super Deluxe are also excellent choices, but each comes with its own set of advantages and drawbacks.

• Marzocchi Bomber Air vs. Fox Float X2: The Fox Float X2 is known for its high level of adjustability, particularly in its high-speed compression. However, the Bomber Air is generally considered more durable and less prone to requiring frequent service, making it ideal for riders who prioritize reliability.
• Marzocchi Bomber Air vs. RockShox Super Deluxe: The RockShox Super Deluxe offers a smoother ride with more tunability, especially for riders who demand a very specific feel from their shock. The Bomber Air, however, is often preferred by aggressive riders who need a shock that can withstand more abuse.

Compatibility with Other Drivetrain Components

The Bomber Air Rear Shock is compatible with a wide range of drivetrain components, including modern SRAM and Shimano drivetrains. Its mounting system is standard for most modern mountain bike frames, ensuring that it will fit most bikes with ease. When pairing it with other drivetrain components, it’s important to ensure that the frame’s rear triangle is compatible with the shock’s specifications.
