Installation of the Vivid Ultimate Rear Shock

Installing the Vivid Ultimate Rear Shock requires attention to detail and an understanding of the shock’s components and your bike’s frame geometry. Here’s how to properly install this shock:

Preparation

1. Check Compatibility: Ensure your bike frame is compatible with the Vivid Ultimate Rear Shock. This shock is designed for aggressive riders and typically fits frames with a standard eye-to-eye length and stroke.
2. Gather Tools: You will need a torque wrench [paid link], a 5mm Allen wrench [paid link], a 6mm Allen wrench [paid link], and a shock pump.
3. Remove the Old Shock: If you’re replacing an existing shock, begin by loosening and removing the bolts holding the shock in place. Carefully remove the old shock from the frame.

Installation Steps

1. Install the Shock Mounts: Place the Vivid Ultimate Rear Shock into the shock mount on the frame. Ensure that the eyelets align correctly with the mounting holes.
2. Insert Bolts: Insert the mounting bolts through the shock’s eyelets and into the frame’s mounting points. Tighten the bolts securely using a 5mm or 6mm Allen wrench, ensuring they are torqued to the manufacturer’s recommended specifications.
3. Check for Movement: Ensure that the shock moves freely within the mounts. If it feels restricted, check the alignment again to make sure no components are binding.
4. Set Air Pressure: Use a shock pump to inflate the Vivid Ultimate Rear Shock to the recommended air pressure for your rider weight and riding style.
5. Final Inspection: Double-check that all bolts are tight and the shock is properly seated. Ensure the shock functions without any interference.

Adjustment of the Vivid Ultimate Rear Shock

The Vivid Ultimate Rear Shock is known for its tunability, offering a wide range of adjustments that allow riders to fine-tune the shock’s performance for different terrain and riding styles.

Damping Adjustment

The Vivid Ultimate features high and low-speed compression and rebound damping adjustments. Here’s how to adjust each:

1. High-Speed Compression: This controls the shock’s response to big hits and aggressive impacts. To adjust it, turn the high-speed compression knob clockwise for more stiffness (slower compression) or counterclockwise for more sensitivity (faster compression).
2. Low-Speed Compression: Adjusting low-speed compression affects the shock’s performance during slower, less aggressive movements, such as pedaling and braking. Turn the knob clockwise to increase stiffness or counterclockwise to make the shock more plush.
3. Rebound Damping: The rebound knob controls the speed at which the shock returns to its original position after compressing. To prevent excessive bouncing, adjust the rebound to a slower setting (clockwise) for better control on rough terrain or a faster setting (counterclockwise) for smoother, less aggressive rides.

Spring Rate Selection

The Vivid Ultimate allows for different spring options depending on your weight and riding preferences. Make sure to select the correct spring rate (Coil or Air) for your riding style. Coil springs provide more consistent performance, while air springs are adjustable and lighter.

Maintenance of the Vivid Ultimate Rear Shock

Proper maintenance of your Vivid Ultimate Rear Shock will ensure that it performs optimally over time, providing a smoother ride and extending its lifespan. Follow these steps for routine care:

1. Clean the Shock Regularly: After every ride, clean the shock using a damp cloth to remove dirt and debris. Pay special attention to the shock eyelets and seals to prevent dirt from damaging the components.
2. Lubricate the Shock: Periodically, apply lubricant to the shock’s stanchion tubes to reduce friction and enhance performance. Use a lightweight lubricant to prevent dirt accumulation.
3. Check for Leaks: Inspect the shock’s seals and air chamber for any signs of oil or air leakage. If you notice any leaks, it’s time for a seal replacement.
4. Service the Shock: Annually or every 50-100 riding hours, have your shock serviced by a professional. This involves checking the internals, replacing worn-out seals, and ensuring the shock’s damping system is functioning properly.

Troubleshooting Common Set-Up Issues

Even the most advanced suspension systems can encounter issues during setup. Here are a few common problems with the Vivid Ultimate Rear Shock and how to troubleshoot them:

Shock Not Compressing Properly

• Cause: This may be due to incorrect air pressure or an improperly adjusted compression setting.
• Solution: Double-check the air pressure to ensure it aligns with your weight and riding style. Adjust the high and low-speed compression settings to see if that resolves the issue.

Excessive Bounce or Soft Feel

• Cause: This could be caused by a low air pressure setting or inadequate rebound damping.
• Solution: Check the air pressure and ensure it’s within the recommended range. Increase the rebound damping to slow down the shock’s return, preventing the excessive bounce.

Noisy Shock

• Cause: A noisy shock often results from dirt or debris within the shock’s seals or stanchions.
• Solution: Clean the shock thoroughly and lubricate the stanchion tubes. If the noise persists, inspect the seals for damage and replace them if necessary.

Customization and Optimization for Better Performance

To optimize the performance of your Vivid Ultimate Rear Shock, consider the following customizations:

1. Adjust Air Pressure for Your Weight: Start by adjusting the air pressure to suit your weight and riding conditions. A higher air pressure will make the shock stiffer, while a lower pressure will provide more plushness and comfort.
2. Tune Damping for Specific Terrain: Use the shock’s high and low-speed compression to adjust to different types of terrain. For smoother trails, a softer compression setting will provide better comfort, while stiffer settings are ideal for aggressive downhill riding.
3. Upgrade Springs: Depending on your preferences and weight, upgrading to a different spring (e.g., from a standard coil to a more progressive air spring) can help improve the shock’s responsiveness and performance.

Comparison with Similar Models

The Vivid Ultimate Rear Shock competes with several other high-performance shocks on the market. Compared to other models, such as the Fox DHX2 and the Ohlins TTX22M, the Vivid Ultimate offers superior tuneability with its range of high-speed compression, low-speed compression, and rebound damping adjustments. It’s particularly well-suited for riders who demand ultimate control over their shock settings and prioritize a plush ride without sacrificing stability on rough terrain.

In terms of performance, the Vivid Ultimate shines when tuned correctly, providing excellent bottom-out resistance and minimizing fatigue during long, technical descents. The Fox DHX2, while similar in its adjustability, tends to feel a bit firmer in its default settings. The Ohlins TTX22M is often chosen by riders who prefer a coil shock, but the Vivid Ultimate’s air spring offers lighter weight and easier adjustability.

Understanding Compatibility with Other Drivetrain Components

When installing the Vivid Ultimate Rear Shock, ensure compatibility with your bike’s other drivetrain components. This shock is designed for modern mountain bikes and can be used with most high-performance suspension bikes. However, always check the shock’s eye-to-eye length and stroke size to match your bike frame’s specifications. Additionally, ensure that your bike’s rear triangle has the necessary clearance to accommodate the shock’s size and mounting type.

The Vivid Ultimate works seamlessly with a wide range of drivetrain components, including SRAM Eagle and Shimano XT. It’s important to ensure that your suspension setup is balanced with your drivetrain, as this will maximize overall performance.
