The Marzocchi Bomber CR Coil [paid link] Rear Shock is a powerful and reliable suspension component designed to elevate the performance of your mountain bike. Known for its durability, customizable features, and excellent ride quality, the Bomber CR Coil [paid link] is particularly favored by riders seeking a smooth, consistent ride over challenging terrain. This guide will take you through the installation, maintenance, troubleshooting, and optimization of the Bomber CR Coil Rear Shock, and provide insight into its compatibility and comparison with other rear shocks.

Installation of the Bomber CR Coil Rear Shock

Proper installation of the Bomber CR Coil is crucial to ensure optimal performance and longevity. Follow these steps to install the shock correctly:

Tools Required:

  • Torque wrench [paid link]
  • 5mm and 8mm Allen wrenches [paid link]
  • Socket wrench
  • Shock mount hardware (specific to your bike)
  • Grease
  • Cleaning rag

Installation Steps:

  1. Prepare the Shock Mounts: Before installing the shock, ensure that the shock mount hardware on your bike is clean and free of any debris. Apply a thin layer of grease to the threads of the mount bolts to prevent seizing.
  2. Position the Shock: Align the Bomber CR Coil’s eyelet with the mounting points on your bike’s rear triangle. The shock’s larger eyelet should fit into the frame’s mounting tab while the smaller eyelet should align with the swingarm or link.
  3. Install the Mounting Bolts: Insert the mounting bolts through the shock’s eyelets and secure them with the appropriate tools. Tighten the bolts to the manufacturer’s recommended torque specifications to avoid over-tightening, which could damage the shock or frame.
  4. Adjust the Spring Preload: After installing the shock, adjust the spring preload to suit your weight and riding style. This can be done by rotating the preload collar until the desired sag is achieved.

Adjustment and Maintenance of the Bomber CR Coil

The Bomber CR Coil Rear Shock is designed to be user-friendly and offers easy adjustments to accommodate different riders and conditions. Proper maintenance will ensure the shock performs at its best for years.

Spring Preload Adjustment:

  • The Bomber CR Coil uses a coil spring that is adjustable for preload. This allows you to fine-tune the shock’s response based on your weight, riding style, and terrain.
  • To adjust the preload, rotate the spring’s preload collar to increase or decrease tension. More preload will make the shock stiffer, while less preload will provide a softer ride.
  • It is essential to set the correct preload to achieve the ideal sag (usually around 25-30% of the total shock travel).

Rebound and Compression Settings:

  • The Bomber CR Coil offers external rebound and compression adjustments. Rebound controls how quickly the shock returns to its neutral position after compressing, while compression determines how the shock handles impacts.
  • Rebound Adjustment: Turn the rebound knob to the right for slower rebound (better for controlling aggressive terrain) or to the left for faster rebound (better for smoother, faster terrain).
  • Compression Adjustment: Similar to rebound, adjust the compression settings to tailor the shock’s behavior. Stiffer compression provides more control on rough terrain, while softer compression can improve comfort on smoother trails.

Regular Maintenance:

  • Inspect the shock after every ride for signs of wear, such as oil leakage or excessive play in the mounting hardware.
  • Clean the shock with a damp cloth after each ride to remove dirt and debris.
  • Perform a full service every 50-100 hours of riding, depending on the conditions. This may include oil changes and inspection of internal seals and components.

Troubleshooting Common Setup Issues

While the Bomber CR Coil Rear Shock is built for durability, improper setup or maintenance can lead to performance issues. Below are common problems and their solutions:

Problem 1: Poor Ride Quality

Solution:

  • Check the spring preload and adjust it to achieve the correct sag. Incorrect sag can lead to poor performance and comfort. Ensure you have set the sag between 25-30% of the total travel.
  • If rebound feels too slow or too fast, adjust the rebound setting to better suit your riding style and terrain.

Problem 2: Bottoming Out or Excessive Travel

Solution:

  • If the shock is bottoming out frequently, increase the compression damping to control how the shock reacts to large impacts.
  • Alternatively, you may need to increase the spring preload or switch to a firmer spring if the rider’s weight or riding style demands it.

Problem 3: Noisy Shock

Solution:

  • Noise can result from insufficient lubrication on the shock’s bushings. Apply grease to the shock’s eyelets and ensure they are properly installed.
  • If the noise persists, inspect the shock for any damage to the seals or other internal components that might require a service.

Customization and Optimization for Better Performance

To fully optimize the performance of your Bomber CR Coil Rear Shock, consider customizing it based on your riding style, terrain, and preferences. Here are a few ways to enhance the shock’s performance:

Choosing the Right Spring Rate:

  • The Bomber CR Coil is available in various spring rates, and selecting the correct one is crucial for achieving the optimal ride quality. Riders who weigh more will require a firmer spring, while lighter riders may benefit from a softer spring.
  • Test the shock after installing a new spring and adjust the preload for the ideal sag. If the bike feels too harsh or too soft, consider swapping out the coil for a different spring rate.

Fine-Tuning Damping Settings:

  • Adjust both compression and rebound settings to match the terrain you are riding. For example, on technical trails, a slower rebound setting can prevent the shock from bouncing back too quickly, allowing for more control over rough sections.
  • On smoother trails, a faster rebound may be preferable to improve efficiency and comfort.

Comparison with Similar Rear Shocks

When comparing the Bomber CR Coil Rear Shock with other similar models, it stands out in several key areas:

  • Versus RockShox Super Deluxe Coil: While the RockShox Super Deluxe Coil is a strong competitor, the Bomber CR Coil typically offers a more forgiving feel and smoother ride over aggressive terrain due to its straightforward adjustability and durable coil spring.
  • Versus Fox DHX2: The Fox DHX2 offers more high-end features, such as a dual-speed compression adjustment and greater fine-tuning options. However, the Bomber CR Coil offers a more user-friendly setup with its fewer adjustments, making it a great choice for riders who prioritize simplicity without sacrificing performance.

Compatibility with Other Drivetrain Components

The Bomber CR Coil Rear Shock is compatible with most modern mountain bike frames that support coil shocks. However, there are a few key considerations to ensure the best performance:

  • Frame Compatibility: Make sure that your frame is designed for a coil shock. Coil shocks require specific mount hardware, which may vary depending on the frame design and shock stroke length.
  • Wheel Travel and Geometry: Check that the travel of the Bomber CR Coil is compatible with your bike’s suspension geometry. The shock’s stroke length should match the bike’s design to avoid damaging the frame or affecting performance.

By ensuring compatibility and selecting the right spring rate, you can maximize the performance of the Bomber CR Coil Rear Shock, offering a smooth and controlled ride on any terrain.
