Installation and Setup of the Bomber Air Trunnion Rear Shock
Installing the Bomber Air [paid link] Trunnion rear shock is a straightforward process, but it’s essential to follow the correct steps to ensure optimal performance. Here is a breakdown of the installation process:
- Prepare Your Tools
Before you begin, make sure you have the necessary tools to install the shock properly. Having the right equipment will save time and prevent damage to your bike frame or shock. - Remove the Old Shock
If you are replacing an existing shock, carefully remove it by loosening the bolts holding it in place. This will typically involve removing both the top and bottom bolts that connect the shock to the frame and the linkage. - Install the Bomber Air [paid link] Trunnion
Place the Bomber Air Trunnion in the same position as the removed shock. Tighten the bolts to secure the shock, ensuring that the shock is properly aligned with the frame. - Set the Air Pressure
Adjust the air pressure based on your body weight and riding style. The Bomber Air Trunnion allows for precise air pressure adjustments, which are crucial for achieving the best performance. - Fine-tune the Compression and Rebound Settings
Set the compression and rebound settings according to your riding preferences. These adjustments will help you fine-tune the shock to match different terrain conditions and riding styles. - Check for Proper Functionality
After installation, cycle the suspension a few times to ensure everything is functioning properly. Check for any unusual noises or resistance.
Maintenance of the Bomber Air Trunnion Rear Shock
Regular maintenance is crucial for keeping your Bomber Air Trunnion rear shock in peak [paid link] condition. The following maintenance tasks will help prolong the life of the shock and maintain its performance:
- Air Pressure Checks
Regularly check and adjust the air pressure in the shock. Over time, air can leak, affecting performance. Ensuring the correct pressure is maintained will optimize your ride and improve overall suspension performance. - Clean the Shock
Keep the shock clean to avoid dirt and debris buildup, which can cause wear. After each ride, wipe down the shock with a damp cloth, especially around the seals and the trunnion mount area. - Lubricate Moving Parts
Periodically lubricate the moving parts of the shock, including the air sleeve and damper. This will help maintain smooth motion and reduce friction, ensuring better performance and longevity. - Inspect the Seals
Check the shock seals regularly for any signs of wear or damage. Damaged seals can lead to air leaks or oil loss, compromising the shock’s performance. Replace seals if necessary. - Service Intervals
Follow Marzocchi’s recommended service intervals to fully service the shock. This usually involves sending it to a service center for a complete teardown and rebuild, which will help maintain the shock’s performance over the long term.
Troubleshooting Common Issues with the Bomber Air Trunnion Rear Shock
While the Bomber Air Trunnion is a high-quality rear shock, there may be a few issues you encounter over time. Here are some common problems and how to troubleshoot them:
- Reduced Performance or Sag
If the rear shock feels excessively soft or sags too much during rides, it could be due to low air pressure. Check and adjust the air pressure to the recommended levels based on your weight and riding style. - No Rebound or Sticking
If you notice that the shock’s rebound isn’t functioning properly or the shock feels like it’s sticking, it could be a sign of internal damper issues. This may require a professional service to check and repair the damper. - Noise from the Shock
Occasional noise, such as a creaking or squeaking sound, is often caused by dirt, debris, or dry seals. Clean the shock thoroughly and lubricate the moving parts to resolve the issue. If the noise persists, check the seals for wear and tear. - Oil Leaks
If you spot any oil around the shock body or mounting areas, this indicates a seal failure. The seals may need to be replaced, or you may need to send the shock in for a complete rebuild.
Customization and Optimization for Better Performance
The Bomber Air Trunnion rear shock offers a range of features that allow you to customize and optimize the shock to better suit your riding needs. Below are some key customization options:
- Air Pressure Adjustment
The Bomber Air Trunnion allows precise control over air pressure, which directly impacts the shock’s performance. Adjusting air pressure to your body weight and preferred riding style is critical for achieving the best suspension performance. - Compression and Rebound Damping
Adjust the compression and rebound settings for improved control and comfort. By fine-tuning these settings, you can ensure the shock responds optimally to various terrain types, from smooth trails to rocky descents. - Progressivity
Experiment with different air volume spacers to adjust the shock’s progressiveness. This allows you to fine-tune the shock’s behavior, making it more suited for aggressive riding or providing a more plush feel for smoother rides. - Spring Rate Adjustments
The Bomber Air Trunnion uses air as its spring medium, but you can adjust the spring rate by changing the air pressure. This gives riders the ability to optimize the shock based on their weight and specific riding preferences.
Compatibility with Other Drivetrain Components
One of the advantages of the Bomber Air Trunnion rear shock is its compatibility with various drivetrain components, which ensures a smooth integration into most modern mountain bike setups. Here’s a closer look at its compatibility:
- Frame Compatibility
The Bomber Air Trunnion is designed to fit most modern full-suspension frames that use a trunnion mount shock. Ensure your frame has the correct trunnion mount dimensions before installation. - Shock Mounting
The shock features a trunnion mount, which is increasingly popular in newer mountain bike designs. This type of mount provides better stiffness and reduced weight compared to traditional eyelet-mounted shocks. - Linkage and Suspension System
The Bomber Air Trunnion is compatible with a wide range of suspension linkages, including those that use a single-pivot or multi-link suspension system. Ensure the shock’s travel length is compatible with your frame’s suspension design for optimal performance.
Comparison with Similar Models
When comparing the Bomber Air Trunnion to other similar rear shocks, the Marzocchi model stands out due to its reliable performance and budget-friendly pricing. While it may not offer the extensive adjustability of some higher-end models, it delivers an excellent balance of performance and durability. Here’s how it stacks up:
