Installation of the Vivid Air R2C Rear Shock
The installation of the Vivid Air R2C rear shock requires a precise process to ensure it functions correctly and safely. Here’s a step-by-step guide to installing the rear shock on your bike.
Step 1: Remove the Old Shock
If you’re replacing an existing shock, begin by removing it from the frame. Use the appropriate hex wrench (typically 5mm) to undo the bolts securing the shock to the frame at both ends. Keep these bolts in a safe place for reinstallation or for potential use with your new shock.
Step 2: Inspect the Shock Mounts
Before installing the new shock, inspect the shock mounts on the frame for any damage or wear. Check for any dirt or debris and clean thoroughly. Apply a light coating of anti-seize lubricant to the shock mount bolts to ensure smooth installation and prevent seizing.
Step 3: Attach the Vivid Air R2C Shock
Align the Vivid Air R2C shock with the shock mounts. Insert the shock’s eyelets into the mounting points on the frame. Tighten the mounting bolts to the manufacturer’s recommended torque setting. Typically, this will be in the range of 25-30Nm for the mounting bolts, but always refer to your bike’s manual for exact specifications.
Step 4: Set the Air Pressure
Using the shock pump, set the air pressure based on your weight and riding style. The Vivid Air R2C allows for a wide range of adjustments, and getting the correct air pressure is crucial for optimizing performance. Begin with a general guideline (e.g., 200-220 psi for a rider weighing around 75kg) and adjust based on personal preference and riding conditions.
Step 5: Fine-Tuning the Setup
Once the shock is in place and air pressure is set, perform a few test compressions. Adjust the rebound and compression damping settings as needed to match your riding style and terrain.
Adjustments and Tuning of the Vivid Air R2C
The Vivid Air R2C offers a range of adjustments that can drastically alter the shock’s performance. Fine-tuning these settings will ensure you get the most out of your suspension system.
Rebound Adjustment
The rebound setting controls how quickly the shock returns after compressing. For a smooth ride, set the rebound so the shock returns quickly but without causing the bike to bounce uncontrollably. If the rebound is too fast, it may cause instability, while a slow rebound can make the bike feel sluggish and unresponsive.
Compression Adjustment
The compression damping adjusts the shock’s resistance during compression. This setting can be fine-tuned for a smoother ride or more efficient pedaling. Set it to a lower setting for more plushness on rough trails and a higher setting for firmer, more efficient pedaling on smoother terrain.
Bottom-Out Control
The Vivid Air R2C features an adjustable bottom-out control that helps prevent the shock from compressing too much on big hits. This feature can be crucial for riders who tackle technical sections and need more progressive damping on severe impacts.
Volume Spacers
If you find that the shock feels too progressive or not progressive enough, you can adjust the volume spacers. These small components adjust the air spring curve, giving you more control over how the shock feels during the mid-to-end stroke. Experiment with different spacer setups to find the optimal balance.
Maintenance of the Vivid Air R2C
Maintaining the Vivid Air R2C rear shock is essential for ensuring its longevity and optimal performance. Here’s how to keep your shock in top shape.
Regular Cleaning
After every ride, it’s important to wipe down the shock to remove any dirt or debris. Use a clean rag and a suitable cleaning solution to keep the shock’s body free of contaminants. Be cautious not to use harsh solvents that could damage the shock’s seals.
Air Pressure Check
Check the air pressure regularly, especially before long rides or after changes in temperature. Air pressure can fluctuate, so it’s essential to maintain the recommended PSI for your weight and riding conditions.
Seals and Lubrication
Over time, the seals on the shock may degrade or wear out. It’s important to check the seals for signs of damage, such as leakage or excessive play. If the seals appear worn, consider replacing them. You should also lubricate the shock’s moving parts periodically to prevent excessive friction.
Annual Overhaul
Depending on the frequency and intensity of your rides, you should perform a full service of the shock at least once a year. This involves disassembling the shock, cleaning the internal parts, and replacing worn seals. It’s recommended to have this done by a professional bike mechanic to ensure the shock is reassembled and tuned properly.
Troubleshooting Common Issues with the Vivid Air R2C
Even the best shocks can encounter issues from time to time. Here are some common problems and their potential solutions.
Loss of Air Pressure
If you notice a loss of air pressure, it’s likely that the shock’s valve is leaking. Check for visible damage to the valve and ensure the valve cap is properly secured. If the valve is intact but air is still leaking, the seals may need to be replaced.
Lack of Rebound Control
If the rebound adjustment seems ineffective, it could be due to insufficient lubrication or worn-out seals. Disassemble the shock to inspect the internals, and reapply lubrication if necessary. If the seals are damaged, replacing them will restore the shock’s rebound performance.
Bottoming Out Too Easily
If the shock is bottoming out too easily, it could be due to insufficient air pressure or a lack of compression damping. Increase the air pressure or adjust the compression settings to provide more resistance during impacts. Adding or removing volume spacers can also help control bottom-out.
Customization and Optimization for Better Performance
To maximize the performance of your Vivid Air R2C shock, consider these customization tips:
- Adjust air pressure based on riding conditions: For technical descents, increase the air pressure for a firmer feel. For cross-country or smoother trails, lower the air pressure for more plushness.
- Fine-tune the damping settings: Make small adjustments to the rebound and compression settings to find the perfect balance for your riding style. Start with the manufacturer’s baseline settings and tweak them as you ride.
- Use different volume spacers: Experiment with adding or removing volume spacers to adjust the shock’s progression. This is particularly useful if you’re transitioning between different types of terrain or riding styles.
Comparison with Other Rear Shocks
The Vivid Air R2C rear shock stands out in the market for its combination of adjustability and performance. Compared to other rear shocks, such as the Fox Float X2 or DVO Jade X, the Vivid Air R2C offers a slightly different damping system that is highly customizable. The Fox Float X2 is known for its more aggressive, race-oriented feel, whereas the Vivid Air R2C focuses on all-around performance with fine-tuned control over both compression and rebound. The DVO Jade X offers a more linear progression, which is ideal for riders who prioritize a more forgiving ride.
When choosing between these shocks, it comes down to personal preference and the type of riding you do. If you prioritize precise tuning and an adaptable shock for a variety of conditions, the Vivid Air R2C is an excellent choice.
Compatibility with Other Drivetrain Components
The Vivid Air R2C rear shock is designed to be compatible with a wide range of mountain bike frames and drivetrain systems. However, always ensure that your frame has the correct shock mount specifications to accommodate the Vivid Air R2C. If you are upgrading from a coil shock, it is important to confirm that the frame can support the air shock’s mounting system.
It’s also essential to consider the overall suspension design of your bike when installing the Vivid Air R2C. Make sure the shock’s tuning aligns with the bike’s frame and the other components in the suspension system.
