Disassembling the Bomber Air Rear Shock
Before you start servicing your Bomber Air rear shock, it’s important to remove it from your bike. Follow these steps:
- Prepare Your Workspace
Ensure that you have a clean, dry, and well-lit area to work in. Place your bike on a stand to stabilize it during the disassembly. - Remove the Shock from the Bike
Use an 8mm Allen wrench to remove the bolts securing the shock to the frame. Keep these bolts and washers in a safe place as you will need them for reassembly. - Release the Air Pressure
Use a shock pump to slowly release any remaining air pressure from the shock. Be sure to do this gradually to avoid damage to the shock or injury.
Cleaning the Bomber Air Rear Shock
A clean shock is crucial for smooth performance and longevity. Here’s how to clean your Bomber Air shock:
- Clean the Shock Body
Use a rag and degreaser to gently clean the shock body. Be sure to remove any dirt, mud, or debris that may have accumulated. Pay extra attention to the seals and the air chamber. - Inspect the Shock for Damage
While cleaning, carefully inspect the shock for any visible damage such as scratches, dents, or oil leakage. If you notice any serious damage, it may be necessary to replace the shock or consult a professional.
Rebuilding the Bomber Air Rear Shock
Rebuilding the shock is a crucial part of the servicing process. Follow these steps to ensure proper performance after servicing.
- Remove the Damper Assembly
Once the shock is cleaned and free from air pressure, use a 10mm open-end wrench to remove the damper assembly. Carefully detach it from the air chamber. - Drain Old Suspension Fluid
With the damper assembly removed, drain any old suspension fluid. This ensures that no contaminated fluid remains in the shock, which could negatively impact its performance. - Replace the Suspension Fluid
Refill the damper assembly with fresh suspension fluid. Make sure to use Marzocchi-approved fluid to maintain optimal performance. Follow the manufacturer’s guidelines for the proper amount of fluid to use. - Reassemble the Shock
After replacing the fluid, carefully reassemble the damper assembly into the air chamber. Be sure to tighten all parts to the manufacturer’s recommended torque specifications using a torque wrench [paid link]. - Lubricate Seals and Moving Parts
Apply a small amount of suspension grease to the seals and other moving parts to ensure smooth operation. This step is important to prevent friction and prolong the life of your shock.
Reinstalling the Bomber Air Rear Shock
After completing the rebuild, it’s time to reinstall the shock onto your bike.
- Install the Shock Back into the Frame
Align the shock with the mounting points on the frame and insert the bolts. Tighten them securely using an 8mm Allen wrench. Be sure to torque them to the correct specifications. - Set the Correct Air Pressure
Use a shock pump to inflate the shock to the correct air pressure. Refer to Marzocchi’s recommended air pressure chart for your rider weight and riding style. A properly set air pressure ensures optimal performance.
Adjusting the Bomber Air Rear Shock
To get the most out of your Bomber Air rear shock, make fine adjustments to suit your riding style and terrain. These adjustments will help with comfort and handling:
- Rebound Adjustment
The rebound adjustment controls how quickly the shock returns after compression. Turn the rebound knob to find the setting that works best for you. A slower rebound may be more comfortable for rough trails, while a faster rebound may be better for smoother rides. - Compression Adjustment
The Bomber Air shock may also feature compression adjustments to control how much the shock compresses under load. Adjusting this can improve handling on various trail conditions, offering better control during aggressive riding or steep descents.
Troubleshooting Common Issues
Even with regular maintenance, problems may arise. Here’s how to troubleshoot common issues with your Bomber Air rear shock:
- Shock Bottoming Out
If your shock bottoms out, it may be due to too little air pressure or insufficient compression damping. Check the air pressure and increase it if necessary. Also, adjust the compression settings for better control. - Excessive Rebound
If the shock rebounds too quickly after compression, turn the rebound adjustment knob to a slower setting. This will ensure that the shock responds more gradually to bumps and impacts. - Oil Leaks
Oil leakage can happen if the seals or damper assembly are worn out. In this case, disassemble the shock and inspect the seals. Replace any worn-out parts and refill the suspension fluid.
Optimizing the Bomber Air Rear Shock for Better Performance
Once you’ve completed the basic maintenance and adjustments, consider these tips for optimizing the performance of your Bomber Air rear shock:
- Tune the Shock for Your Riding Style
Experiment with air pressure and rebound settings to find the ideal balance between comfort and control. Lighter riders may prefer softer settings, while heavier riders may need firmer settings to prevent bottoming out. - Regular Maintenance
Make it a habit to clean and inspect your shock regularly, especially after rides in muddy or wet conditions. This ensures that dirt and debris don’t accumulate, potentially damaging the shock. - Keep Seals Lubricated
Proper lubrication of the seals ensures smooth operation and prevents friction, which can lead to premature wear. Always use Marzocchi-recommended suspension grease for the best results.
Bomber Air Rear Shock vs. Other Models
If you’re considering the Bomber Air rear shock and comparing it to similar models, here’s a quick rundown of its key advantages:
- Marzocchi Bomber Air vs. Fox Float DPX2
The Bomber Air is known for its durable build and simplicity, making it ideal for riders who prefer easy maintenance and solid performance. The Fox Float DPX2, on the other hand, offers more fine-tuned adjustments but can be more complex to maintain. - Marzocchi Bomber Air vs. RockShox Super Deluxe
Both shocks offer impressive performance, but the Bomber Air is often seen as more forgiving on rough terrain due to its straightforward design. The RockShox Super Deluxe offers more adjustability for riders who prefer customized setups but may require more frequent servicing.
Understanding Compatibility with Other Drivetrain Components
When servicing the Bomber Air rear shock, it’s important to understand its compatibility with other components of your bike, especially the drivetrain. Ensure that your shock’s performance matches the overall setup of your bike. If you have a more aggressive drivetrain with high-end suspension forks, you might want to tune the Bomber Air for a firmer setup. Conversely, for a more casual setup, a softer shock may provide better comfort.
By following these steps, you can service your Marzocchi Bomber Air rear shock and keep it performing like new. Regular maintenance and adjustments are key to ensuring the shock delivers consistent performance, providing you with a smoother, more enjoyable ride.
