The Marzocchi Bomber Air [paid link] rear shock is a popular choice among mountain bikers, known for its performance, durability, and adjustability. Designed for a variety of mountain biking styles, this rear shock is particularly favored by riders seeking a high-performance shock that can handle aggressive trails while providing a smooth, controlled ride. In this guide, we will explore its installation, adjustment, maintenance, troubleshooting, and optimization, while also comparing it to other similar rear shocks to help riders determine if it is the best option for their mountain biking needs.

Installation of the Bomber Air Rear Shock

Installing the Marzocchi Bomber Air [paid link] rear shock requires careful attention to detail. It is essential to ensure that the shock is securely mounted, and the settings are correctly configured for your riding style. Here’s a step-by-step guide for the installation process:

1. Remove the Old Shock
   • Use a wrench to detach the bolts securing the old shock.
   • Carefully remove the shock from the bike frame, noting the position and orientation of the mounting hardware for the new shock.
2. Check Shock Compatibility
   • Ensure that the Bomber Air is compatible with your frame size and mounting standards. This shock is designed for a wide range of bike frames, but it is essential to verify the correct eye-to-eye length and stroke for proper fitment.
3. Install the Bomber Air Shock
   • Position the Bomber Air rear shock onto the frame, aligning the mounting hardware with the shock’s eyelets.
   • Secure the shock with the appropriate bolts, ensuring that they are torqued to the manufacturer’s recommended specifications.
4. Check for Clearance
   • Ensure there is adequate clearance between the shock and the frame, including the linkages and rear triangle. This will prevent any interference during suspension movement.
5. Final Tightening and Inspection
   • Tighten all bolts to the correct torque and check for any movement or play in the shock. Ensure the shock is mounted securely and is free from any rattling.

Adjustment of the Bomber Air Rear Shock

Adjusting the Bomber Air rear shock is key to optimizing performance for different terrains. This shock offers a variety of adjustments that allow riders to fine-tune their suspension for different riding conditions.

Rebound and Compression Settings

The Bomber Air features a rebound and compression adjustment, which is crucial for controlling the speed of the shock’s response.

• Rebound: This controls how quickly the shock returns after compression. For rough terrain, a slower rebound might be beneficial to avoid harsh bouncing, while a faster rebound is suitable for smoother trails to maintain better control.
• Compression: Compression adjustments allow you to fine-tune how the shock compresses when it absorbs impacts. On aggressive trails, increasing compression can prevent bottoming out, while reducing compression can improve comfort on smoother terrain.

Air Pressure Adjustment

The Bomber Air uses air as its spring, and adjusting the air pressure is vital for achieving the correct sag. Sag is the amount the shock compresses under the rider’s weight, which affects the shock’s performance.

1. Measure your Rider Weight: Start by checking the recommended air pressure based on your body weight.
2. Adjust the Air Pressure: Use a shock pump to add or remove air until the desired sag is achieved. Typically, a sag of around 25-30% is ideal for most riders.

Bottom-Out Resistance

This feature ensures that the shock doesn’t compress beyond a certain point, which can be essential when riding over large drops or aggressive obstacles. Adjusting the bottom-out resistance prevents the shock from bottoming out and enhances control in more demanding situations.

Maintenance of the Bomber Air Rear Shock

Maintaining the Bomber Air rear shock is crucial for preserving its performance and extending its lifespan. Regular maintenance is necessary to keep the shock in optimal condition, especially if riding in harsh conditions or wet environments.

Regular Cleaning

After every ride, clean the shock to remove dirt, mud, and debris. Use a soft cloth or brush to gently wipe the shock body and seals. Avoid using harsh chemicals or pressure washers, as they can damage the shock or seals.

Air Sleeve Maintenance

The Bomber Air’s air sleeve should be serviced periodically. Over time, the air sleeve can accumulate oil and debris, which can impact the shock’s performance. To maintain optimal performance:

• Remove the shock from the bike and disassemble the air sleeve.
• Clean the sleeve thoroughly and re-oil it with fresh suspension oil to ensure smooth movement and prevent wear on the seals.

Rebuilding the Shock

While the Bomber Air rear shock is designed to be durable, it may require a full rebuild after extended use or if performance starts to degrade. This rebuild includes replacing the seals, changing the oil, and checking for any wear on the internal components.

Troubleshooting Common Set-Up Issues

Even with proper installation and adjustment, riders may encounter a few common set-up issues with the Bomber Air rear shock. Below are some common problems and how to address them.

Sag Too High or Too Low

• Issue: If the sag is too high or low, the shock may not be providing the correct balance of comfort and control.
• Solution: Adjust the air pressure accordingly. If the sag is too low, reduce the air pressure. If it’s too high, increase the air pressure to reach the desired sag percentage.

Loss of Rebound or Compression Adjustments

• Issue: If the rebound or compression adjustments aren’t having any effect, the internal damping system may be clogged or damaged.
• Solution: Clean and service the shock, ensuring the damping circuits are free of debris. If the issue persists, consider a full rebuild of the shock.

Shock Bottoming Out

• Issue: If the shock bottoms out during aggressive riding or large impacts, it may indicate insufficient compression damping or air pressure.
• Solution: Increase the compression damping or add more air to the shock to prevent bottoming out.

Customization and Optimization for Better Performance

For riders who want to get the most out of their Bomber Air rear shock, customization is key. Here are some tips for optimizing performance:

Adjusting for Riding Style

• Aggressive Riders: For riders who prefer aggressive downhill or enduro riding, increasing the air pressure and compression settings can help prevent bottoming out and improve control on rough descents.
• Cross-Country Riders: For lighter riders or those focused on cross-country riding, decreasing the air pressure slightly can offer more comfort and a smoother ride, especially on moderate terrain.

Tuning for Terrain

• Technical Terrain: If you ride a lot of rocky, technical terrain, consider increasing the low-speed compression for better control on small bumps, and fine-tune the rebound for smoother, more controlled responses.
• Flow Trails: For smooth, flowy trails, reduce compression slightly and adjust the rebound to allow for quicker return after each bump, giving you a more lively ride.

Comparison with Other Rear Shocks

When comparing the Bomber Air to other rear shocks in the market, such as the Fox Float X2 or RockShox Super Deluxe, several factors come into play:

• Performance: The Bomber Air is known for its consistent performance across various riding styles. It provides a more plush feel compared to other air shocks, making it ideal for aggressive riding.
• Weight: The Bomber Air is lighter than some other high-performance shocks, such as the Fox Float X2, making it an appealing choice for riders looking to minimize weight without sacrificing performance.
• Price: The Bomber Air is generally more affordable than its competitors like the Fox Float X2, making it an excellent value for riders who want high-quality performance at a reasonable price point.

Compatibility with Other Drivetrain Components

The Bomber Air rear shock is designed to work seamlessly with a wide variety of mountain bike drivetrain components, including Shimano, SRAM, and other top brands. However, it’s important to check the compatibility of your bike’s frame and suspension linkage to ensure that the shock will perform optimally.

Some bike frames may require specific mounting hardware or have particular geometries that influence shock performance. Always verify the shock’s compatibility with your bike’s geometry and suspension system before installation.
