The Marzocchi Bomber Air [paid link] rear shock is designed to offer superior performance, adjustability, and durability for mountain bikers seeking a reliable suspension system. As an integral component of a mountain bike’s suspension system, the rear shock plays a pivotal role in absorbing impacts and providing a smooth, controlled ride. In this article, we will compare the Bomber Air [paid link] rear shock to similar models in the market, evaluate its installation, adjustment, and maintenance procedures, and discuss its compatibility with other drivetrain components.

Installation of the Bomber Air Rear Shock

Installing the Marzocchi Bomber Air rear shock is straightforward but requires precision for optimal performance. Here are the key steps:

1. Remove the Old Shock: If replacing an existing shock, begin by removing it from the bike frame. Use the appropriate wrenches to detach the shock bolts. Ensure you do not lose any spacers or hardware during the removal process.
2. Check Frame and Shock Compatibility: Before installation, verify that the Bomber Air shock is compatible with your bike frame. Marzocchi provides a sizing chart for the correct shock dimensions.
3. Install the Bomber Air Shock: Position the shock on the bike frame, ensuring that the eyelet on each side aligns properly with the shock mount. Secure the shock with bolts and ensure they are tightened to the manufacturer’s torque specifications.
4. Check Air Pressure: Using a shock pump, adjust the air pressure to match your body weight and riding style. This is crucial for achieving the correct sag and ride feel.
5. Test the Shock: Before riding, perform a few manual compressions of the shock to ensure everything is functioning smoothly.

Adjustment and Maintenance of the Bomber Air Rear Shock

The Bomber Air rear shock offers multiple adjustment features, including air pressure, rebound, and compression settings. These adjustments allow riders to fine-tune their ride to suit different terrains and personal preferences.

Air Pressure Adjustment

• Purpose: Air pressure controls the shock’s firmness and determines the sag—the amount the shock compresses under the rider’s weight.
• How to Adjust: Use a shock pump to add or release air from the shock’s air chamber. Marzocchi provides a recommended air pressure range based on the rider’s weight, which is a good starting point.
• Tip: Start with the recommended air pressure, then experiment with slight changes to fine-tune the suspension. If you feel too much bottoming out or excessive stiffening, adjust accordingly.

Rebound Adjustment

• Purpose: Rebound controls how quickly the shock returns to its original position after compressing. Too slow a rebound can cause the bike to feel sluggish, while too fast can cause a bouncy ride.
• How to Adjust: Use the rebound knob located on the shock’s body to either slow down or speed up the rebound rate. Turn the knob clockwise to slow it down and counterclockwise to speed it up.
• Tip: Start with the mid-range setting and adjust based on your riding style and terrain. Slower rebound is typically better for more aggressive trails, while faster rebound may be preferred for smoother tracks.

Compression Adjustment

• Purpose: Compression controls how much the shock resists when compressed. It affects the bike’s response to different terrain, providing more control on rough trails or increased comfort on smoother paths.
• How to Adjust: The Bomber Air features a low-speed compression adjustment knob. Turning it adjusts the shock’s resistance to slower compressions, such as during pedal strokes or braking.
• Tip: For technical or steep trails, increasing the compression setting may improve control and prevent excessive bobbing. For more flowy rides, lower compression may be better for comfort.

Regular Maintenance

• Clean the Shock: After each ride, wipe down the shock to remove dirt and debris that can cause wear and tear.
• Check for Leaks: Periodically inspect the shock for any oil or air leaks, as these can affect performance.
• Lubrication: Ensure the shock’s seals and bushings are well-lubricated to prevent friction and extend the shock’s lifespan.
• Service Intervals: Follow Marzocchi’s recommended service intervals for air sleeve maintenance and internal servicing to ensure consistent performance.

Troubleshooting Common Bomber Air Rear Shock Set-Up Issues

Insufficient Sag or Bottoming Out

• Cause: The air pressure might be too low for the rider’s weight, or the rebound setting could be too fast, not allowing the shock to return properly.
• Solution: Increase the air pressure or adjust the rebound setting. Check the manufacturer’s recommended pressure range and adjust accordingly.

Excessive Bounciness or Poor Pedaling Efficiency

• Cause: This issue is typically due to too much air pressure or an improper compression setting.
• Solution: Lower the air pressure slightly and adjust the low-speed compression to provide better pedaling performance.

Noisy Shock

• Cause: Noises could be caused by dirt or debris inside the shock or dry seals.
• Solution: Clean the shock regularly and lubricate the seals. If the noise persists, consider servicing the shock.

Customization and Optimization for Better Performance

The Bomber Air rear shock is highly customizable to suit different riding styles. Here are a few optimization tips:

• Adjust Air Pressure for Personal Sag: Rider weight significantly affects sag, and adjusting air pressure is essential for a balanced ride. Use a sag meter to measure sag at the shock’s full extension and ensure it’s in the recommended range (typically 25-30%).
• Fine-Tune Rebound: For riders tackling technical trails, consider setting a slower rebound to maintain control when dropping into rough terrain. Alternatively, for smoother rides, faster rebound can keep the bike lively.
• Compression for Pedal Efficiency: Adjust the low-speed compression to reduce pedal bobbing during climbs or long rides. A firmer compression setting can improve pedal efficiency while preventing unwanted suspension movement.

Comparison with Similar Models

When comparing the Bomber Air rear shock to its competition, several models come to mind, including the Fox Float X and RockShox Super Deluxe. Here’s how the Bomber Air stands out:

• Marzocchi Bomber Air: Known for its durability and consistent performance, the Bomber Air is ideal for aggressive riders who want robust suspension at a more affordable price point. It’s designed with simplicity in mind, offering easy adjustments without too much complexity.
• Fox Float X: The Fox Float X offers a more refined damping system, with additional high-speed compression adjustments that provide precise tuning for advanced riders. It’s also lighter than the Bomber Air, making it a good choice for those prioritizing weight savings.
• RockShox Super Deluxe: This shock offers excellent small-bump compliance, providing superior comfort on rough trails. The Super Deluxe is generally more tuned for all-around use, offering a more plush ride compared to the Bomber Air, but it lacks the ruggedness and cost-effectiveness that the Bomber Air offers.

Compatibility with Other Drivetrain Components

The Bomber Air rear shock is designed to work seamlessly with various mountain bike frames and drivetrains, but compatibility with other components is crucial for achieving the best performance.

• Frame Compatibility: Ensure that the shock’s mounting hardware and length match your bike’s frame specifications. The Bomber Air is designed to fit a wide range of mountain bike frames, including both cross-country and enduro styles.
• Suspension Linkage: The Bomber Air performs optimally when paired with a suspension linkage that accommodates air shocks. Make sure the shock’s stroke length is suitable for your bike’s rear triangle.
• Drivetrain Compatibility: The rear shock doesn’t directly interact with the drivetrain but can affect pedaling efficiency and comfort. When paired with a drivetrain that includes a high-quality drivetrain and components like a smooth cassette or chain, the Bomber Air ensures a responsive, controlled ride.

In conclusion, the Marzocchi Bomber Air rear shock offers great value for aggressive riders, providing performance that competes with higher-end shocks at a more accessible price. Whether you’re looking to replace an older shock or optimize your current suspension system, the Bomber Air can be easily adjusted to meet various riding conditions. With the right adjustments and maintenance, it can enhance your mountain biking experience significantly.
