Installation of the Bomber CR Coil Rear Shock

Installing the Marzocchi Bomber CR Coil rear shock correctly is crucial for optimal performance. Here’s a step-by-step guide to ensure you install it safely and efficiently:

1. Prepare Your Bike
   • Secure your bike on a work stand, ensuring it’s stable.
   • Remove the rear wheel if necessary for easier access to the rear triangle.
2. Remove the Existing Shock
   • Use the appropriate tools to remove the bolts securing the old shock to the frame.
   • Pay attention to the orientation of the shock for proper installation later.
3. Install the Bomber CR Coil Rear Shock
   • Align the Bomber CR Coil shock with the mount points on the rear triangle.
   • Insert the bolts and torque them to the manufacturer’s recommended settings. Ensure they are snug but not over-tightened.
4. Reinstall the Rear Wheel
   • Once the shock is in place, reinstall the rear wheel if it was removed. Make sure it is securely fastened.
5. Check for Clearance and Movement
   • Before finalizing the installation, check for any potential clearance issues between the shock and the frame.
   • Ensure the rear shock has full travel without any restrictions.

Adjustment of the Bomber CR Coil Rear Shock

The Bomber CR Coil rear shock offers several adjustable features, allowing riders to fine-tune the shock to their preferences. Here’s how to adjust it for maximum performance:

Spring Rate Adjustment

The Bomber CR Coil comes with a coil spring, which can be adjusted for preload. By adjusting the preload, you can fine-tune the spring’s stiffness to match your riding style and weight.

• Increase preload by turning the preload collar clockwise to stiffen the spring, providing more support for heavier riders or aggressive riding.
• Decrease preload by turning the collar counterclockwise to soften the spring, ideal for lighter riders or less aggressive riding conditions.

Compression Damping Adjustment

Compression damping controls how the shock absorbs impacts, and the Bomber CR Coil features a simple, tool-free compression adjuster.

• Increase compression damping for a firmer, more controlled response on rough terrain.
• Decrease compression damping for a more plush feel on smoother trails or when additional sensitivity is required.

Rebound Damping Adjustment

Rebound damping determines how quickly the shock returns to its original position after compression. Proper rebound settings prevent the shock from being too fast or too slow, which could affect control.

• Faster rebound (clockwise) is suitable for smoother conditions or when you want more responsiveness.
• Slower rebound (counterclockwise) is ideal for rougher terrain, providing more control.

Fine-Tuning for Performance

• Start with the manufacturer’s baseline settings, and adjust the rebound and compression damping based on your riding preferences. Always make small adjustments and test ride the bike to feel the difference.

Maintenance of the Bomber CR Coil Rear Shock

To ensure long-lasting performance and smooth operation, regular maintenance of the Bomber CR Coil rear shock is essential. Here are some key maintenance tasks:

Cleaning and Lubrication

• Clean the shock after each ride to remove dirt and debris, especially in wet or muddy conditions.
• Use a soft cloth to wipe down the shock, being careful not to scratch the stanchion tube.
• Lubricate the shock regularly to reduce friction. Use oil designed for suspension systems to lubricate the spring and moving parts.

Spring and Seal Maintenance

• Inspect the spring for signs of wear, such as scratches or rust. If necessary, replace the coil spring to maintain optimal performance.
• Check the seals for any signs of oil leakage or wear. Seals are crucial to keep dirt and moisture out of the shock’s internals, so replace them if they show signs of damage.

Full Servicing

• Schedule a full service every 100-150 hours of ride time or annually, whichever comes first. This will involve disassembling the shock, cleaning and re-oiling the internals, and replacing worn components like seals or bushings.

Troubleshooting Common Issues with the Bomber CR Coil Rear Shock

Although the Bomber CR Coil rear shock is known for its reliability, issues can arise over time. Below are some common problems and solutions:

Lack of Rebound Control

If the shock feels like it’s not returning to its original position properly, check the rebound damping settings. If the rebound is too slow, turn the adjuster counterclockwise to speed it up. If the shock feels sluggish despite adjusting, the internal oil might need a change, or the seals might be damaged.

Excessive Sag

If the shock sags too much under your weight, the spring rate may be too soft. Increase the preload to stiffen the spring or consider swapping to a stronger coil if the current one is not suitable for your weight.

Noisy Operation

If the shock starts making unusual noises, such as creaks or squeaks, it could be due to dirt buildup or lack of lubrication. Clean the shock thoroughly and lubricate the moving parts. If the noise persists, check the bushings and seals for wear.

Customization and Optimization for Better Performance

To fully optimize the Bomber CR Coil rear shock, consider the following tips for enhanced performance:

Adjusting for Different Terrain Types

• For technical descents or rocky trails, use more compression damping and slower rebound to enhance stability.
• On flowy trails, you may prefer a softer compression setting and faster rebound to maintain comfort and agility.

Coil Spring Swap

If you find that the stock coil spring doesn’t suit your weight or riding style, Marzocchi offers different spring options. Swapping to a firmer or softer coil can significantly improve the performance for riders with different weight ranges.

Fine-Tuning Damping for Weight

• Riders on the lighter side can benefit from reducing the compression damping for better sensitivity.
• Heavier riders should focus on increasing the compression damping and preload for more control and less sag.

Comparison with Similar Models

When compared to other rear shocks in the same class, the Bomber CR Coil offers superior durability and ease of maintenance. While models like the Fox DHX2 and RockShox Super Deluxe Coil offer similar performance features, the Bomber CR Coil stands out for its simple, user-friendly adjustments and solid build quality. It’s also more cost-effective, making it a great choice for riders looking for high-end performance at a slightly lower price point.

Bomber CR Coil vs. Fox DHX2

• Adjustment Range: The Bomber CR Coil offers simpler adjustments compared to the DHX2, which includes more advanced settings but can be more complex to fine-tune.
• Build Quality: Both shocks are highly durable, but the Bomber CR Coil uses a straightforward coil system, making it easier to maintain.
• Price: The Bomber CR Coil is generally more affordable, offering comparable performance at a lower cost.

Bomber CR Coil vs. RockShox Super Deluxe Coil

• Performance: Both shocks offer great performance on aggressive trails, but the Bomber CR Coil tends to provide a slightly more plush feel, while the Super Deluxe Coil might offer a firmer, more precise response.
• Adjustments: The Bomber CR Coil offers easy-to-use adjustments, whereas the Super Deluxe has more fine-tuning options for experienced riders.

Compatibility with Other Drivetrain Components

The Bomber CR Coil rear shock is compatible with a wide range of mountain bike setups. However, it’s essential to check the frame’s rear triangle for compatibility with the shock’s eye-to-eye length and stroke length. Ensure that the shock’s travel is suitable for the type of riding you plan to do.

If you’re running a high-performance drivetrain, like SRAM Eagle or Shimano XT, the Bomber CR Coil works well with these systems due to its smooth shock action and ability to handle aggressive riding styles.
