Key Features of the Vivid Ultimate Rear Shock
The Vivid Ultimate rear shock from RockShox comes packed with features aimed at delivering optimal suspension performance. These features include:
- R1C (Rebound, Compression, and High-Speed Compression Adjustments): Offering a high level of adjustability, the Vivid Ultimate allows riders to fine-tune the shock for various trail conditions.
- DebonAir™ Spring: This spring technology provides a more linear progression, offering smoother small bump compliance while maintaining excellent mid-stroke support.
- RC2 Damper: A dual damper system that enhances rebound and compression control, providing more stability on aggressive terrain.
- Velocity Sensitive Damping (VSD): The damper automatically adjusts to changing terrain, providing consistent performance across all sections of the trail.
- External Adjustments: Multiple adjustments for low-speed rebound, high-speed rebound, and compression settings ensure that riders can dial in the shock to their exact preferences.
Installation of the Vivid Ultimate Rear Shock
Installing the Vivid Ultimate rear shock requires precision and attention to detail. Follow these steps to ensure a proper setup:
- Tools Required:
- Torque wrench [paid link]
- 8mm Allen wrench [paid link]
- 10mm spanner wrench (for locknut)
- Suspension grease
- 2.5mm, 3mm, and 5mm Allen keys [paid link] (for fine adjustments)
- Remove the Old Shock:
- Remove any rear-wheel hardware to gain access to the shock mount.
- Use an Allen wrench [paid link] to loosen the bolts securing the old shock in place.
- Carefully remove the shock from its mount.
- Prepare the Vivid Ultimate Shock:
- Apply a light layer of suspension grease to the shock’s mounting hardware and pivot points.
- Ensure the shock is clean and free of debris before installation.
- Install the Vivid Ultimate Shock:
- Align the shock with the mounting points on the bike frame.
- Secure the shock in place by tightening the bolts using the torque wrench [paid link] to the manufacturer’s recommended torque settings (typically around 100-120Nm).
- Double-check that all hardware is secured tightly and that the shock is properly aligned.
- Check the Suspension Linkage:
- Before finalizing the installation, cycle the suspension to ensure smooth movement.
- If any binding or excessive resistance is felt, check the shock placement and linkage.
Adjusting the Vivid Ultimate Rear Shock
Once installed, the Vivid Ultimate rear shock offers a wide range of adjustments that can be tailored to suit different riding styles and conditions. Here’s a breakdown of the main adjustments and how they affect ride quality:
Rebound Adjustments
The Vivid Ultimate provides fine-tuned control over rebound damping. Adjusting rebound affects how quickly the shock returns to its neutral position after compression. A slower rebound provides better control in rough sections but can make the bike feel sluggish, while a faster rebound helps with high-speed stability but may cause the bike to feel “bouncy.”
- Slower rebound: Improves control on rough terrain.
- Faster rebound: Helps in fast, smooth sections but can lead to instability if overdone.
Compression Adjustments
The compression settings manage how the shock reacts to impacts and forces from terrain. Adjusting compression affects how much the shock absorbs impacts versus how much it resists them. A softer compression setting offers more comfort and absorption, while a firmer compression setting enhances support and stability.
- Low-speed compression: Primarily impacts smaller bumps and cornering support.
- High-speed compression: Affects large hits and high-velocity impacts, providing better control on aggressive trails.
Spring Rate and Air Pressure
The DebonAir™ spring on the Vivid Ultimate rear shock offers excellent small bump sensitivity. Riders should adjust the spring rate by modifying the air pressure within the shock to match their weight, riding style, and the terrain they are tackling. For heavier riders or those riding on more aggressive terrain, a higher air pressure may be required to avoid bottoming out.
Troubleshooting Common Issues with the Vivid Ultimate Rear Shock
While the Vivid Ultimate rear shock is designed for performance, like any component, it may encounter issues. Here are common problems and solutions:
1. Shock Bottoming Out
Cause: This issue can occur if the spring rate or air pressure is too low, or if the compression settings are too soft.
Solution: Increase the air pressure slightly or adjust the compression settings to provide better resistance to bottoming out. Ensure the shock’s spring rate matches the rider’s weight and riding style.
2. Lack of Rebound Control
Cause: If the shock is not returning quickly enough, it could be a sign of too much rebound damping, or the oil inside the damper may have degraded.
Solution: Try reducing the rebound damping slightly and test the shock’s response. If the problem persists, a suspension service may be required to replace the oil and inspect the damper components.
3. Leaking Shock
Cause: Leaks can be a sign of worn seals or damage to the shock body.
Solution: Inspect the shock body and seals for any visible damage or wear. If leaking is occurring, it’s best to take the shock to a professional for a full rebuild, including replacing seals and oil.
Optimizing the Vivid Ultimate Rear Shock for Performance
For riders looking to maximize the performance of their Vivid Ultimate rear shock, fine-tuning the shock to their specific needs is crucial. Riders should focus on the following adjustments:
- Set the correct sag: Adjust the air pressure to achieve proper sag (usually around 30% of the shock’s total travel). This ensures the shock operates within its optimal range and prevents harsh bottom-outs or excessive bobbing.
- Dial in rebound and compression: Experiment with various rebound and compression settings to find the balance between control and comfort.
- Regular maintenance: Keeping the shock clean and performing regular maintenance, including periodic oil changes and seal inspections, will prolong the shock’s lifespan and performance.
Comparison with Other Rear Shocks
When compared to other high-performance rear shocks, the Vivid Ultimate stands out due to its combination of advanced technology and adjustability. Models like the Fox DHX2 and Öhlins TTX22M offer similar performance but may differ in terms of ease of tuning and overall ride feel.
- Fox DHX2: Known for its high-speed compression adjustability and linear feel, this shock can be an excellent alternative for riders who prefer a slightly different feel compared to the Vivid Ultimate.
- Öhlins TTX22M: Offers exceptional damping performance, especially on high-speed hits. However, it may be less forgiving in certain mid-stroke sections, making the Vivid Ultimate a more versatile [paid link] option for riders who seek a smoother, more consistent ride.
Compatibility with Other Drivetrain Components
The Vivid Ultimate rear shock is compatible with a wide variety of mountain bike frames and drivetrain components. However, compatibility must be confirmed based on the bike’s suspension geometry and shock mount spacing. Before installation, always verify the shock’s specifications with your bike’s manufacturer to ensure a proper fit. Additionally, pairing the Vivid Ultimate with a compatible front fork from RockShox or other brands will enhance overall suspension performance and provide a balanced ride.
By focusing on compatibility, you can ensure that the shock works seamlessly with your bike’s frame and other drivetrain components, helping to optimize ride quality across all types of terrain.
