The Vivid Coil R2C rear shock from RockShox is a standout component for mountain bikers looking to elevate their ride experience. Engineered for aggressive riders and those seeking ultimate control and performance on technical descents, this shock is designed to handle rough terrain with ease. In this guide, we’ll break down everything you need to know about the Vivid Coil R2C, including installation, maintenance, troubleshooting, and performance optimization, helping you maximize its potential.

Installation of the Vivid Coil R2C Rear Shock

Installing the Vivid Coil R2C rear shock requires precision and care to ensure it functions correctly. Proper installation ensures you get the best performance and longevity out of your shock.

Step-by-Step Installation

1. Prepare the Bike: Before starting the installation, make sure the bike is on a stable surface and the rear wheel is removed to access the shock. Use a bike stand [paid link] for added stability.
2. Remove the Old Shock (if applicable):
   • Using a wrench, remove the bolts securing the existing shock.
   • Take note of the shock’s mounting orientation before removing it.
3. Install the Vivid Coil R2C:
   • Position the Vivid Coil R2C shock in the frame’s shock mount.
   • Align the shock’s eyelets with the frame mounts. Ensure the shock is installed with the correct orientation, as indicated by the manufacturer.
   • Insert and tighten the mounting bolts to the recommended torque settings to ensure the shock is securely attached.
4. Reinstall the Rear Wheel: After the shock is installed, put the rear wheel back in place and double-check the clearance and alignment of the shock and wheel.
5. Adjust Settings: Once the shock is installed, adjust the settings, including the coil preload and rebound damping, to your riding style and preferences.

Adjustment and Customization for Better Performance

The Vivid Coil R2C features advanced adjustability to fine-tune your ride. This flexibility allows riders to customize the shock to their needs for both comfort and performance.

Rebound Damping Adjustment

• Purpose: Rebound damping controls the speed at which the shock returns to its original position after compression. The right setting helps you maintain control on rough terrain and during aggressive riding.
• How to Adjust: Use the rebound knob located at the base of the shock. Turn it clockwise to slow down the rebound and counterclockwise to increase speed. Start with a neutral setting and make adjustments based on your riding style and conditions.

Coil Preload Adjustment

• Purpose: The coil preload determines how much the spring compresses when you sit on the bike. This adjustment is crucial for achieving the right balance and avoiding bottoming out.
• How to Adjust: The preload collar can be rotated using a spanner tool. Tighten the collar to increase preload and loosen it to reduce preload. Aim for a sag of around 30% of the total shock stroke when sitting on the bike.

High-Speed Compression and Low-Speed Compression

• Purpose: These adjustments control how the shock responds to different types of impacts. High-speed compression is for handling large hits, while low-speed compression affects the shock’s behavior on smaller, more consistent bumps.
• How to Adjust: Turn the compression knobs at the top of the shock. Use the high-speed compression knob to adjust for bigger impacts and the low-speed compression knob for better control on smaller terrain features.

Fine-Tuning the Settings

Once the primary adjustments are made, it’s important to fine-tune the shock by riding and adjusting the settings based on feedback. Make small adjustments to each setting, testing the shock’s performance on your typical trails.

Troubleshooting Common Set-Up Issues

Although the Vivid Coil R2C is built to offer high performance, riders may encounter common issues during set-up or while riding. Understanding these issues and how to troubleshoot them can help keep your ride smooth.

Shock Bottoming Out

Cause: If the shock is bottoming out too frequently, the coil preload may be too low, or the compression damping may not be set properly for the terrain.

Solution: Increase the preload or adjust the compression damping settings to prevent the shock from bottoming out. Try increasing the low-speed compression for more support on smaller bumps.

Excessive Rebound Speed

Cause: If the shock is rebounding too quickly, it can cause instability, especially on technical descents.

Solution: Slow down the rebound by turning the rebound knob clockwise. This will give the shock more control and help you maintain stability.

Inconsistent Performance

Cause: If the shock feels inconsistent, it may be due to incorrect air pressure (if applicable), improper coil preload, or a lack of maintenance.

Solution: Check the coil preload to ensure proper sag. Additionally, inspect the shock for any leaks or damage and make sure all bolts are tightened to specification.

Maintenance and Care

To ensure the longevity of the Vivid Coil R2C and maintain its optimal performance, regular maintenance is required. Here’s how to care for the shock.

Regular Cleaning

• After every ride, clean the shock with mild soap and water to remove dirt and debris.
• Avoid using high-pressure water or harsh solvents, which can damage the seals.

Periodic Servicing

• It’s recommended to service the shock at least once per year, depending on riding frequency and conditions. A full service includes inspecting the shock for wear, replacing seals, and lubricating the internal components.

Checking for Leaks

• Periodically inspect the shock for any oil leaks around the seals. If you notice any leakage, it’s crucial to have the shock serviced to avoid damage to the internal components.

Compatibility with Other Drivetrain Components

The Vivid Coil R2C rear shock is designed to integrate seamlessly with a variety of mountain bike frames and drivetrains. However, it’s essential to verify that the shock’s specifications align with your bike’s geometry and drivetrain components.

Frame Compatibility

• Ensure your frame has the correct shock mount type and dimensions to accommodate the Vivid Coil R2C. The shock is compatible with both traditional and modern frames, but double-check the eyelet size and shock stroke before purchasing.

Drivetrain Considerations

• Although the rear shock does not directly affect drivetrain performance, it does influence overall ride quality. Consider the balance between the suspension and drivetrain for optimal performance. For aggressive riding or enduro setups, pairing the Vivid Coil R2C with a reliable drivetrain will enhance the bike’s overall responsiveness.

Comparison with Similar Models

When choosing a rear shock, comparing the Vivid Coil R2C to similar models can help riders make an informed decision.

Vivid Coil R2C vs. Fox DHX2

• Performance: Both shocks offer exceptional performance for downhill and enduro riding. The Vivid Coil R2C has slightly more adjustability in terms of rebound and compression settings, while the Fox DHX2 is known for its smoother action on long descents.
• Weight: The Fox DHX2 tends to be lighter, which may be preferable for riders prioritizing weight savings.
• Price: The Vivid Coil R2C is generally more budget-friendly compared to the Fox DHX2, making it an excellent option for riders looking for performance without the premium price tag.

Vivid Coil R2C vs. RockShox Super Deluxe Coil

• Technology: The Super Deluxe Coil features a more modern damper system with better small-bump sensitivity, while the Vivid Coil R2C is still an excellent choice for aggressive riders on rougher terrain.
• Adjustability: The Vivid Coil R2C offers a more comprehensive range of adjustments, making it better suited for riders looking to fine-tune their suspension for varied conditions.

Conclusion

The RockShox Vivid Coil R2C rear shock stands as one of the top choices for aggressive mountain bikers looking to enhance ride quality. With its advanced adjustability, robust performance, and compatibility with a wide range of bikes, it offers riders the control and comfort needed for high-speed descents and technical trails. Regular maintenance and thoughtful adjustments can ensure this shock continues to perform at its best for years to come.
