Installation of the Bomber CR Coil Rear Shock

The installation process for the Bomber CR Coil rear shock is straightforward but requires attention to detail to ensure proper fitment and optimal performance. Here is the step-by-step guide to installing the shock onto your bike.

Tools Required:

• 8mm and 10mm Allen wrenches [paid link]
• Torque wrench [paid link]
• Flathead screwdriver
• Shock mounting hardware (if not included with the shock)
• Grease for hardware

Step-by-Step Installation:

1. Prepare the Rear Triangle: Before installing the Bomber CR Coil rear shock, ensure that the rear triangle of your bike is clean and free from debris. It’s important to inspect the shock mounting points to ensure they are free of damage or excessive wear.
2. Install the Shock Hardware: Begin by attaching the mounting hardware to the Bomber CR Coil rear shock. The shock typically includes two sets of bushings. Slide the bushings into the shock eyelets, ensuring they fit snugly.
3. Mount the Shock: Position the shock into the rear triangle of your bike, aligning the shock’s eyelets with the frame’s mounting points. Carefully insert the bolts through the shock’s eyelets and the frame.
4. Tighten the Bolts: Using the 8mm and 10mm Allen wrenches [paid link], tighten the bolts securing the shock to the frame. Be sure to use a torque wrench [paid link] to tighten the bolts to the manufacturer-recommended torque settings to avoid over-tightening or under-tightening.
5. Check Alignment and Function: Once the shock is installed, check that it is aligned properly and moves freely. Compress the shock to ensure there is no binding or resistance, which could indicate an installation issue.
6. Final Check: Double-check all bolts and hardware to ensure everything is securely fastened before riding. Perform a quick test ride to confirm that the shock is functioning correctly.

Adjustment of Bomber CR Coil Rear Shock

The Bomber CR Coil rear shock offers a variety of adjustments that can significantly improve your bike’s performance. Fine-tuning these settings will allow you to adapt the shock to your riding style and terrain.

Key Adjustments:

1. Sag Setting:
   • The sag refers to how much the shock compresses under your weight. For the Bomber CR Coil, the ideal sag typically falls between 25% to 30% of the shock’s total travel.
   • To adjust the sag, you may need to change the coil spring. Use the shock’s preload adjuster to modify the spring tension and achieve the correct sag.
2. Rebound Damping:
   • Rebound damping controls the speed at which the shock returns to its original position after compression.
   • Adjust the rebound knob to make the shock’s rebound faster or slower. If you feel the shock is too bouncy, slow it down. If it’s sluggish, speed it up.
3. Compression Damping:
   • Compression damping controls the shock’s resistance to compression under impact.
   • Adjust the compression knob to set how the shock reacts to bumps. For smoother rides, you may want to soften the compression, while a firmer setting is ideal for aggressive, high-speed riding.
4. Air Pressure (If applicable):
   • Some Bomber CR Coil shocks may allow adjustments to air pressure or utilize a hybrid air-spring system. Adjust this pressure to match your weight and riding style.

Maintenance of Bomber CR Coil Rear Shock

Routine maintenance is essential to keep your Bomber CR Coil rear shock performing at its best. Regular servicing helps extend the lifespan of the shock and ensures you get the best ride possible.

Cleaning:

• After every ride, clean the shock with a soft brush and water to remove dirt and debris.
• Use a mild soap solution if necessary but avoid harsh chemicals or solvents that could damage the shock’s finish or seals.
• Pay special attention to the eyelets, spring, and shock seals to ensure no dirt or grit gets into the internal components.

Lubrication:

• Apply a light layer of grease to the shock’s mounting hardware and pivot points to reduce friction and prevent wear.
• Avoid over-greasing, as excess grease can attract dirt, which may lead to premature wear.

Regular Inspection:

• Inspect the shock for any signs of damage or wear, particularly the seals and bushings.
• Check for any oil leakage, which may indicate internal damage or worn seals. If you notice any issues, consider servicing or replacing the affected parts.

Spring Maintenance:

• Coil springs may lose some tension over time. If you notice a significant decrease in performance, it may be necessary to replace the coil spring.
• Regularly check for any damage to the spring, such as rust or deep scratches, which can affect its performance.

Troubleshooting Common Set-Up Issues

Even with proper installation and maintenance, issues can sometimes arise with your Bomber CR Coil rear shock. Here are some common problems and how to troubleshoot them:

1. Shock Bottoming Out:
   • This occurs when the shock compresses too much, often due to an incorrect sag setting. Adjust the preload to achieve the correct sag or consider switching to a stiffer coil spring.
2. Excessive Rebound:
   • If the shock rebounds too quickly, you may feel a “bouncy” sensation. Adjust the rebound damping to slow down the return rate.
3. Leaking Fluid:
   • If you notice oil leaking from the shock, it may be a sign of damaged seals or internal issues. Contact a professional for service and seal replacement.
4. Noise or Creaking:
   • If the shock produces strange noises, check the mounting hardware and ensure the shock is properly lubricated. Clean and lubricate the shock’s pivot points if necessary.

Customization and Optimization for Better Performance

The Bomber CR Coil rear shock is highly customizable, allowing you to optimize your setup based on your riding style and terrain. Here are some tips for fine-tuning the shock:

• Coil Spring Selection: The coil spring is a crucial component of the shock’s performance. Choose a spring with the appropriate spring rate based on your weight and riding style. A stiffer spring is ideal for aggressive riding or heavy riders, while a softer spring is better for lighter riders or those focusing on comfort.
• Adjusting for Terrain: For rough, technical trails, increase the compression damping to handle large impacts. For smoother trails, reduce the compression damping for a more plush ride.
• Rebound Adjustment for Control: If you are tackling steep descents, consider slowing the rebound to maintain better control over the shock’s return. Faster rebound can be beneficial for more technical sections with quick, sharp impacts.

Comparison with Similar Models

When considering rear shocks for your bike, the Bomber CR Coil competes with several similar models in the market, such as the Fox Van R and RockShox Super Deluxe Coil. While all of these shocks offer reliable performance, the Bomber CR Coil is known for its durability and ease of tuning. It stands out in terms of its heavy-duty build, making it ideal for riders who require a tough shock that can handle aggressive riding.

In comparison, the Fox Van R provides a slightly more refined ride but may be better suited for riders who prioritize weight savings and advanced features. The RockShox Super Deluxe Coil, on the other hand, offers adjustable features such as high-speed compression, which may appeal to more experienced riders looking for fine-tuned control.

Compatibility with Other Drivetrain Components

The Bomber CR Coil rear shock is designed to be compatible with a wide range of mountain bikes, especially those with a coil suspension system. However, it is important to ensure compatibility with the rest of your drivetrain components, such as the frame and the shock’s mounting hardware. Always check the specifications of your bike frame to confirm that the Bomber CR Coil can be mounted without issues.

It is also essential to match the coil spring with your body weight and riding style for optimal performance. The shock should work seamlessly with other suspension components, ensuring smooth operation and consistent performance.
