Installation of the Vivid Ultimate Rear Shock
The installation of the RockShox Vivid Ultimate rear shock requires careful attention to detail to ensure optimal performance and safety. This process can be broken down into a few simple steps:
- Remove the Old Shock
If you are replacing an existing shock, begin by removing it from the bike frame. Use a 5mm Allen wrench [paid link] to loosen the mounting bolts at both ends of the shock. Keep the bolts and bushings safe for re-use or replacement. - Prepare the Vivid Ultimate Shock
Before installation, ensure the Vivid Ultimate rear shock is in proper working order. Check the shock for any visible damage, and ensure the air canister is properly sealed. Optionally, you can grease the bushings to facilitate a smooth installation. - Install the New Shock
Attach the shock to the frame’s rear shock mounts, aligning the upper and lower mounting hardware. Use a 5mm Allen wrench to tighten the mounting bolts on the shock. Be sure to tighten the bolts evenly to the torque specifications provided in the RockShox manual. - Install the Shock Pump
Attach your shock pump to the air valve on the shock and begin adjusting the pressure. Start with the recommended pressure based on your body weight and riding style, which can typically be found in the manual or on the shock itself. - Check for Proper Function
After installation, compress and extend the shock by hand to ensure smooth operation. The shock should move freely without any signs of resistance or stiffness.
Adjusting the Vivid Ultimate Rear Shock
Once installed, the Vivid Ultimate offers an array of adjustability features to tailor the shock’s performance to your riding preferences. Key adjustments include the air pressure, rebound damping, and compression settings. Here’s how to make these adjustments:
1. Air Pressure Adjustment
The air pressure in the shock significantly impacts how it behaves on the trail. Higher pressure results in a firmer shock, while lower pressure allows for more plushness.
- How to Adjust: Use a shock pump to adjust the air pressure through the Schrader valve. The recommended air pressure is typically specified based on rider weight and riding style.
- Tip: Always start with the manufacturer’s recommended pressure. From there, you can fine-tune it based on your riding experience, adjusting in small increments.
2. Rebound Damping
Rebound damping controls how quickly the shock extends after being compressed. Too much rebound damping can make the shock feel sluggish, while too little can cause the shock to extend too quickly, resulting in a bouncy ride.
- How to Adjust: Locate the rebound adjuster on the Vivid Ultimate. Turn it clockwise to increase damping (slower rebound) and counterclockwise to decrease damping (faster rebound).
- Tip: Adjust the rebound to your preferred riding style, ensuring that the shock is responsive but not too quick to rebound.
3. Compression Damping
Compression damping affects how the shock compresses under force. The Vivid Ultimate features both high-speed and low-speed compression adjustments, which allow you to fine-tune the shock’s behavior under different types of impact.
- How to Adjust: Use the compression knobs to adjust the low-speed and high-speed compression. Start with the low-speed dial first, making adjustments for the desired level of firmness. Then, adjust the high-speed compression to control how the shock reacts to big hits.
- Tip: If you find the shock too soft on big hits, increase the high-speed compression to prevent bottoming out. For smoother, smaller hits, dial back the compression to allow the shock to absorb trail imperfections more effectively.
Troubleshooting Common Setup Issues
While tuning your Vivid Ultimate rear shock, you may encounter some common issues that could affect its performance. Here’s how to troubleshoot these problems:
1. Shock Bottoming Out
- Possible Cause: Too little air pressure or insufficient high-speed compression.
- Solution: Increase air pressure and adjust the high-speed compression to prevent the shock from bottoming out under heavy impacts.
2. Lack of Small-Bump Sensitivity
- Possible Cause: Too much air pressure or too much compression damping.
- Solution: Decrease air pressure slightly and reduce compression damping to allow the shock to react better to small bumps and trail chatter.
3. Excessive Rebound
- Possible Cause: Too little rebound damping, causing the shock to rebound too quickly.
- Solution: Increase the rebound damping by turning the rebound knob clockwise to slow down the shock’s extension.
Optimizing the Vivid Ultimate for Better Performance
The Vivid Ultimate is known for its customizability, and there are several ways to fine-tune the shock for different riding conditions and styles. To get the best performance from your shock, consider the following:
1. Use the Right Spring Rate
The Vivid Ultimate rear shock allows for a variety of spring options. Choose the right spring rate based on your body weight and riding style. For heavier riders or aggressive riding, a stiffer spring will provide better support. Lighter riders may benefit from a softer spring to maintain plushness without bottoming out.
2. Optimize Rebound and Compression for Terrain
Adjust your shock’s settings to match the type of terrain you’ll be riding. For aggressive downhill riding, stiffer compression and slower rebound will provide better control. For trail riding, a softer setup will provide better comfort and efficiency.
3. Regular Maintenance and Service
The Vivid Ultimate is a premium rear shock, and to ensure it lasts, regular maintenance is crucial. Clean the shock after each ride to prevent dirt from damaging the seals. Periodically check the air pressure and compression settings, and have the shock serviced by a professional if you notice any signs of wear or reduced performance.
Comparison with Other Models
While the RockShox Vivid Ultimate offers exceptional performance and adjustability, it’s important to consider how it compares with similar models from other brands. Compared to the Fox Float X2, the Vivid Ultimate is known for its progressive damping and smoother feel on aggressive terrain. However, the Float X2 has slightly more intuitive controls for beginners and may offer a more user-friendly setup process. Both shocks offer similar performance, but the Vivid Ultimate excels in handling big hits and providing a customizable ride.
Compatibility with Other Drivetrain Components
The Vivid Ultimate is compatible with a wide range of drivetrain systems, including SRAM and Shimano setups. However, it’s crucial to ensure that the rear shock is paired with the correct frame and suspension system for optimal performance. Always check with your bike’s manufacturer for compatibility recommendations.
By following these installation, adjustment, and maintenance tips, you’ll be able to get the most from your RockShox Vivid Ultimate rear shock, enhancing your overall riding experience and performance.
