Designed for downhill and enduro riders, this shock is engineered to handle rough terrain while providing a smooth and controlled ride. In this detailed guide, we will explore the installation, adjustment, maintenance, and troubleshooting of the Vivid Coil R2C [paid link], as well as compare it to other similar shocks in the market to help you make an informed decision.
Installation of the Vivid Coil R2C Rear Shock
Installing the RockShox Vivid Coil R2C rear shock requires a solid understanding of bike mechanics. This shock is designed for riders who prioritize high-performance suspension, and its installation demands precision.
Tools Required:
- Torque wrench [paid link]
- 8mm and 10mm Allen wrenches [paid link]
- Shock pump
- Suspension grease
- Small flathead screwdriver
- 5mm and 6mm Allen wrenches [paid link]
Installation Steps:
- Remove the old shock: Begin by detaching the existing rear shock. Use the 8mm and 10mm Allen wrenches to remove the mounting bolts securing the shock to the frame and the linkage.
- Prepare the Vivid Coil R2C: Apply a small amount of suspension grease to the shock’s mounting hardware to ensure smooth installation and prevent seizing over time.
- Mount the shock: Position the Vivid Coil R2C on the rear triangle of the bike, ensuring the shock’s eyelets align with the frame’s mounting points.
- Tighten the bolts: Secure the shock using the appropriate Allen wrenches (usually 8mm for the upper mount and 10mm for the lower mount). Be sure to torque the bolts to the manufacturer’s specifications to avoid damage.
- Set the preload: Use a shock pump to set the initial air pressure in the coil spring to match your weight and riding style. The Vivid Coil R2C offers an adjustable preload system to fine-tune the stiffness.
- Final check: Once installed, check for proper shock alignment and secure mounting before testing.
Adjusting the Vivid Coil R2C Rear Shock
The Vivid Coil R2C comes with a range of adjustments that allow riders to customize the shock to their needs. Key adjustments include rebound damping, compression damping, and preload.
Rebound Damping:
Rebound damping controls how quickly the shock returns to its neutral position after compression. A higher rebound setting will make the shock return more slowly, while a lower setting will allow the shock to return more quickly. Adjust the rebound knob located at the base of the shock to your preferred setting.
Compression Damping:
Compression damping controls how the shock reacts to hits and bumps. The Vivid Coil R2C features an adjustable high-speed and low-speed compression system. These adjustments allow riders to dial in the shock for different terrain types:
- Low-speed compression: Adjusts the shock’s response to small impacts, like pedaling and braking forces.
- High-speed compression: Affects how the shock responds to large impacts, such as drops or big hits.
Start with a medium setting for both high and low-speed compression and adjust based on ride feedback. This will help you fine-tune the shock’s behavior for optimal performance.
Preload Adjustment:
The preload setting allows you to adjust the stiffness of the coil spring to match your weight. To adjust the preload, use a tool to turn the preload collar. Increasing preload makes the shock stiffer, while decreasing it makes the shock softer.
Maintenance of the Vivid Coil R2C Rear Shock
Proper maintenance is essential to ensure the longevity and performance of your RockShox Vivid Coil R2C rear shock. Regular maintenance prevents wear and tear, ensuring smooth operation over time.
Cleaning:
Regularly clean the shock using a soft cloth and warm water. Avoid using harsh chemicals that can damage the shock’s seals or finish. Clean the shock body and the coil spring area, ensuring no dirt or grime builds up that could interfere with the shock’s performance.
Lubrication:
Apply suspension grease to the shock’s mounting hardware during installation and maintenance. Greasing the eyelets helps reduce wear and makes it easier to remove the shock during future maintenance.
Air Can Service:
Although the Vivid Coil R2C is a coil shock, it still includes an air can that requires periodic servicing. Follow the manufacturer’s guidelines for servicing the air can, which typically involves removing the air sleeve, cleaning the seals, and replacing the air oil. Servicing the air can every 50 hours of riding is generally recommended.
Coil Spring Maintenance:
The coil spring itself doesn’t require much maintenance, but it’s important to inspect it periodically for any signs of wear or damage. Clean the spring and ensure that the preload collar moves freely.
Damper Oil Service:
The damper requires regular oil changes. This ensures consistent damping performance and prevents overheating or fading. Typically, a damper oil change is required every 100 hours of riding, depending on the conditions in which the bike is used.
Troubleshooting Common Set-Up Issues
Despite the high-quality engineering of the Vivid Coil R2C, some riders may encounter set-up issues. Here are some common problems and their solutions:
Shock Bottoming Out:
Cause: The shock may be set too soft for the rider’s weight or riding conditions.
Solution: Increase the preload setting to make the shock stiffer, or adjust the compression damping to provide more resistance to big impacts.
No Rebound or Excessive Rebound:
Cause: The rebound adjustment may be set incorrectly.
Solution: Check the rebound damping and adjust the knob to the appropriate setting. If the rebound is too slow, turn the knob to the “faster” setting. If it’s too fast, turn it to the “slower” setting.
Overheating or Fading Damping:
Cause: Lack of proper damper oil or improper oil weight.
Solution: Perform a damper oil change. Ensure that the correct oil weight is used as specified by RockShox.
Customization and Optimization for Better Performance
To get the most out of the Vivid Coil R2C, riders can make several adjustments to optimize performance for their specific needs. These include:
- Tuning the rebound: For aggressive riders or those who frequently encounter large drops, slowing down the rebound helps prevent the bike from kicking back too fast after a heavy impact.
- Adjusting the compression settings: For technical riding, adjust the low-speed compression to control pedal bobbing and maintain traction while riding through rough sections.
- Fine-tuning the preload: Experiment with different preload settings based on your weight and riding style. A stiffer setup may be beneficial for heavier riders or those who prefer a firmer ride, while a softer setup is better for lighter riders and those seeking more comfort.
Comparison with Similar Models
When comparing the RockShox Vivid Coil R2C to other rear shock models, such as the Fox DHX2 and Ohlins TTX22M, the Vivid Coil R2C stands out for its simple design and ease of adjustment.
- Fox DHX2: While the DHX2 offers a more refined dual-speed compression and rebound system, the Vivid Coil R2C’s simpler adjustment options make it more user-friendly for riders who want performance without the need for frequent tinkering.
- Ohlins TTX22M: The TTX22M offers excellent performance with its high-end damping system, but it comes at a significantly higher price point than the Vivid Coil R2C. For riders on a budget, the Vivid Coil R2C is a more accessible alternative without compromising much on performance.
Compatibility with Other Drivetrain Components
The Vivid Coil R2C rear shock is designed to work seamlessly with a wide range of drivetrain components, especially when used with RockShox’s own line of forks and suspension products. However, it’s essential to ensure compatibility with the bike’s rear triangle and linkages.
When installing the shock on your bike, check the dimensions of the mounting eyelets and the shock’s stroke length to ensure proper fitment. Additionally, ensure that the shock’s adjustability doesn’t interfere with other components, such as your chainstay or seatstays.
In conclusion, the RockShox Vivid Coil R2C rear shock is a highly reliable and customizable option for riders who need top-tier suspension performance. By following the installation, adjustment, and maintenance steps outlined above, riders can ensure their shock operates at its peak [paid link], providing an optimal ride experience for demanding downhill and enduro courses.
