The Marzocchi Bomber CR Coil [paid link] Rear Shock is a standout option for riders seeking a high-performance coil shock. Known for its exceptional durability and advanced features, it is tailored for aggressive trail and enduro riders. In this guide, we will dive deep into the installation, maintenance, troubleshooting, and customization of the Bomber CR Coil [paid link], ensuring you get the most out of this high-quality suspension component. We will also compare it with similar models to help you decide whether it’s the right choice for your bike.

Installation of the Bomber CR Coil Rear Shock

The Bomber CR Coil is designed to be compatible with a variety of mountain bikes, especially those with rear suspension. To ensure a smooth installation, follow these steps:

  1. Remove the old shock – Begin by removing your old shock if you’re replacing it. This usually involves removing the bolts that secure the shock to the frame. Keep track of any washers or spacers used.
  2. Check the frame compatibility – Ensure that the Bomber CR Coil shock matches your bike’s rear suspension geometry. The shock’s eyelet size and stroke length must match the design specifications of your bike.
  3. Insert the new shock – Place the Bomber CR Coil shock into the frame. Align the eyelets with the mounting points on the bike. Be careful not to damage the frame or shock during this process.
  4. Secure the shock – Attach the shock by tightening the bolts at both the top and bottom eyelets. Use a torque wrench [paid link] to ensure proper tightening according to Marzocchi’s specifications.
  5. Set sag and preload – Before riding, set the sag and adjust the preload on the coil spring. Proper sag ensures that the shock will perform optimally for your weight and riding style.

Adjusting the Bomber CR Coil Rear Shock

Proper adjustment of the Bomber CR Coil Rear Shock ensures that you get the best performance based on your riding style and terrain. Here’s how to fine-tune the shock:

  1. Preload adjustment – Adjust the preload by turning the coil spring’s preload adjuster. Increasing the preload stiffens the spring, while decreasing it softens the suspension. Ensure that the spring rate is appropriate for your weight and riding style.
  2. Compression adjustment – The Bomber CR features adjustable compression damping. Turn the compression knob to increase or decrease the damping. For aggressive riding or rough terrain, higher compression may be needed, while smoother trails may require less damping.
  3. Rebound adjustment – The rebound knob allows you to adjust the speed at which the shock returns to its extended position. A slower rebound is suited for aggressive riding, while a faster rebound is better for smoother trails.
  4. Sag setting – Adjust the sag by sitting on the bike and checking the amount of travel the shock uses. The ideal sag is usually between 25% and 30% of the shock’s total travel. Adjust the preload to achieve the correct sag for your weight.

Routine Maintenance for the Bomber CR Coil

Routine maintenance is essential for ensuring the Bomber CR Coil performs at its best throughout its lifespan. Follow these maintenance tips to keep your rear shock in top condition:

  1. Clean the shock regularly – Dirt and grime can accumulate on the shock, affecting performance. Use a damp cloth to wipe down the shock after each ride, focusing on the shock body and spring.
  2. Inspect for damage – Check the shock for any signs of damage, such as dents, cracks, or leaks. If any issues are noticed, replace the shock or consult a professional.
  3. Lubricate moving parts – The shock’s bushings should be lubricated periodically to ensure smooth movement. Use a light bike-specific grease for lubrication.
  4. Air out the shock – If you notice any air bubbles inside the shock, especially after heavy use, perform an air bleed procedure according to the manufacturer’s instructions.
  5. Spring maintenance – The coil spring should be checked for wear over time. If you notice any scratches or damage, consider replacing the spring to maintain performance.

Troubleshooting Common Set-Up Issues

Sometimes, riders may encounter issues with their Bomber CR Coil rear shock that can affect its performance. Here are some common problems and solutions:

  1. Shock feels too stiff or too soft – If the shock feels too stiff, try reducing the preload on the coil spring or adjusting the compression damping. If it’s too soft, increase the preload or compression damping.
  2. Excessive bottom-out – If you experience excessive bottom-out during rough descents, increase the compression damping or check the sag to ensure it’s set correctly.
  3. Inconsistent rebound – If the rebound feels uneven or too fast, adjust the rebound knob and ensure it’s not set too high. If problems persist, check for oil contamination or internal damage.
  4. Noisy shock – If you hear squeaking or unusual noises, inspect the bushings and mounts for wear. Lubricate them if necessary or replace worn-out parts.

Customization and Optimization for Better Performance

Optimizing the Bomber CR Coil Rear Shock for different riding conditions and preferences can significantly improve your riding experience. Here’s how you can enhance the performance:

  1. Choose the right spring rate – Select a coil spring with the appropriate spring rate based on your weight and riding style. A coil that’s too stiff will be uncomfortable, while one that’s too soft will result in poor performance.
  2. Fine-tune rebound and compression – Experiment with different compression and rebound settings until you find the perfect balance for your riding style. For instance, riders tackling technical, rough trails will benefit from more compression damping and slower rebound.
  3. Upgrade internal components – Consider upgrading to a custom tuning kit or replacing the shock’s internals to further enhance the Bomber CR’s performance. Custom valving can help achieve a specific riding feel, making the shock better suited for your needs.

Comparison with Similar Models

While the Bomber CR Coil Rear Shock is a top choice for aggressive riders, it’s important to understand how it stacks up against similar models in the market:

  1. Fox DHX2 Coil – The Fox DHX2 is a strong competitor, offering advanced damping adjustments and a lighter weight. However, the Bomber CR Coil tends to provide better value for riders who prefer a more straightforward, robust coil shock without the complexity of numerous adjusters.
  2. RockShox Super Deluxe Coil – The RockShox Super Deluxe is known for its reliability and smooth performance. However, it may not offer the same level of customization and ease of maintenance as the Bomber CR, which is praised for its durability and ease of service.
  3. DVO Jade X – The DVO Jade X offers a smooth ride and highly customizable damping options, but it is typically more expensive and may require more maintenance. The Bomber CR Coil stands out as a more budget-friendly alternative with similar performance for most riders.

Compatibility with Other Drivetrain Components

The Bomber CR Coil Rear Shock is compatible with a wide range of bike frames, particularly those designed for enduro and trail riding. However, it’s important to ensure that your bike’s frame design and suspension linkage are compatible with the Bomber CR’s dimensions. While the shock does not directly affect your drivetrain, the suspension system works in tandem with your drivetrain for overall bike performance. Make sure your bike’s geometry and rear suspension design can accommodate the Bomber CR Coil for optimal performance.
