CR Coil Rear Shock

Installing the Marzocchi Bomber CR Coil Rear Shock is straightforward but requires careful attention to ensure it functions correctly. Follow the steps below for proper installation:

  1. Prepare the bike: Ensure your bike is on a stable stand, and remove the rear wheel to access the rear triangle.
  2. Remove the old shock: If replacing an existing shock, carefully remove it by unscrewing the mounting bolts on both ends. Keep the hardware, as it may be needed for the new shock installation.
  3. Install the Bomber CR Coil Shock: Position the Bomber CR Coil into the rear triangle, aligning the shock’s mounting hardware with the eyelet at both ends. Ensure that the shock is positioned in the correct direction, with the rebound adjuster on the remote side.
  4. Secure the mounting bolts: Tighten the mounting bolts to the manufacturer’s recommended torque specifications. This is crucial to avoid over-tightening or under-tightening, which can lead to improper functioning or damage.
  5. Reinstall the rear wheel: After securing the shock, reinstall the rear wheel, ensuring that everything is aligned and properly fitted.

Adjustment of the Bomber CR Coil Rear Shock

One of the Bomber CR Coil’s standout features is its adjustability. Riders can fine-tune the shock to match their riding style and the terrain. The shock provides several key adjustments for improved comfort and control:

Rebound Adjustment

  • The rebound adjustment controls the speed at which the shock returns after compression. Turning the rebound knob clockwise will slow down the rebound, while turning it counterclockwise will speed it up. Riders should aim for a rebound speed that complements their riding style. Too fast, and the shock will not provide adequate control; too slow, and it may feel sluggish and difficult to manage.

Compression Damping

  • The Bomber CR Coil Rear Shock offers high and low-speed compression adjustments, allowing riders to fine-tune the shock’s responsiveness. High-speed compression affects the shock’s performance during quick hits or big impacts, while low-speed compression controls softer, more gradual compressions. Adjusting both settings ensures maximum control and efficiency.

Spring Rate

  • The spring rate of the Bomber CR Coil can be customized based on the rider’s weight and riding style. A stiffer spring is ideal for heavier riders or those who tackle more aggressive terrain, while a softer spring suits lighter riders or less demanding trails. Choosing the correct spring rate is essential for achieving optimal performance.

Maintenance of the Bomber CR Coil Rear Shock

Proper maintenance of the Bomber CR Coil is key to ensuring its longevity and performance. Regular servicing will help you avoid potential issues and keep your shock performing at its best.

  1. Clean the shock regularly: After each ride, clean the shock with a mild detergent and water to remove dirt and debris. Wipe down the shock body and ensure that the seals are free of contaminants.
  2. Check for air or oil leaks: Inspect the shock for any signs of air or oil leakage. If you notice any, it may indicate a seal failure, which will require servicing.
  3. Lubricate the shock: Occasionally, apply lubricant to the shock’s moving parts to reduce friction and wear. Avoid using excessive lubrication as it can attract dirt.
  4. Inspect the coil spring: Check the coil spring for signs of wear or damage. If the spring has any visible cracks, it should be replaced.
  5. Service the shock annually: It’s recommended to service the Bomber CR Coil Rear Shock at least once a year or after every 100-150 hours of use. This ensures the internal components, such as the damping system and seals, remain in top condition.

Troubleshooting Common Issues with the Bomber CR Coil Rear Shock

Despite its durability and performance, riders may encounter issues with the Bomber CR Coil Rear Shock over time. Here are some common problems and their solutions:

1. Shock Bottoming Out

  • Cause: Bottoming out can occur if the shock’s spring rate is too soft or if the compression damping is insufficient.
  • Solution: Check the spring rate and replace it with a stiffer one if necessary. Adjust the compression settings to provide more support during impacts.

2. Loss of Rebound Control

  • Cause: If the rebound is too fast or too slow, it can affect the shock’s performance.
  • Solution: Adjust the rebound dial to find a setting that offers smooth, controlled rebound. If the issue persists, inspect the rebound damping system for possible issues.

3. Shock Leaking Oil

  • Cause: Oil leakage is often caused by worn-out seals.
  • Solution: Inspect the shock seals for damage or wear. Replace seals as necessary or send the shock to a service center for professional maintenance.

4. Excessive Stiffness or Harshness

  • Cause: This could be due to the wrong spring rate or improper compression settings.
  • Solution: Review and adjust the spring rate to better match your weight and riding style. Fine-tune the compression settings to provide a smoother ride.

Customization and Optimization for Better Performance

Optimizing the Bomber CR Coil Rear Shock is essential for achieving the best performance. Riders can adjust multiple settings to suit their specific needs.

  1. Tuning for Trail Conditions: Adjust the compression and rebound settings based on trail conditions. For aggressive, rocky trails, increase high-speed compression to handle the hits more effectively. On smoother trails, reduce compression for a more supple ride.
  2. Weight Considerations: If you’re on the lighter or heavier side, it’s essential to adjust the spring rate accordingly. Lighter riders will benefit from a softer spring, while heavier riders need a stiffer coil to prevent excessive bottoming out.
  3. Rider Preferences: Fine-tuning your rear shock’s performance to match your riding style—whether you prioritize comfort, responsiveness, or control—ensures maximum satisfaction. Experimenting with the shock’s settings during different types of rides allows for optimization.

Comparison with Similar Models

When comparing the Marzocchi Bomber CR Coil Rear Shock with other similar models, it’s important to consider factors like spring type, adjustability, and overall performance.

Marzocchi Bomber CR Coil vs. Fox DHX2

  • Spring Type: Both models feature coil springs, but the Bomber CR Coil is known for its more straightforward, user-friendly adjustability, while the Fox DHX2 offers a broader range of fine-tuning options.
  • Performance: The Bomber CR Coil is more forgiving and ideal for aggressive trail riders who need a reliable shock with minimal maintenance. The Fox DHX2, on the other hand, excels in high-end performance, particularly for riders who prioritize precision and top-tier handling.
  • Price: The Bomber CR Coil offers a more budget-friendly option for riders who want coil performance without the premium price tag of the Fox DHX2.

Marzocchi Bomber CR Coil vs. RockShox Super Deluxe Coil

  • Adjustability: The Bomber CR Coil provides a solid range of adjustability, particularly with its high and low-speed compression settings. The RockShox Super Deluxe Coil offers similar adjustment capabilities but may be favored for its more refined rebound damping.
  • Ride Quality: Both shocks provide excellent ride quality, but the Bomber CR Coil is more versatile [paid link] for a wide range of riders, from enthusiasts to professionals, while the Super Deluxe Coil is tailored for riders seeking precise handling in varied conditions.
  • Durability: The Bomber CR Coil excels in longevity, particularly for riders who want a no-fuss, dependable shock for heavy-duty use.

Understanding Compatibility with Other Drivetrain Components

The Bomber CR Coil Rear Shock is designed to be compatible with most modern mountain bikes, but it’s essential to verify the shock’s eyelet sizing and shock stroke length to ensure compatibility with your bike’s frame. Most commonly, the Bomber CR Coil fits bikes designed with a standard 190mm shock eyelet. However, always consult the bike manufacturer’s specifications to confirm compatibility.

The shock’s performance is independent of the drivetrain components; however, optimizing the rear suspension’s settings can complement drivetrain adjustments for a smoother overall ride. When selecting your drivetrain components, make sure the rear shock’s settings and adjustments are considered for a seamless riding experience.
