In this guide, we will explore the key features, installation, maintenance, and troubleshooting aspects of the Monarch Plus RC3 rear shock, helping you get the most out of this high-performance component.
Key Features of the Monarch Plus RC3
The Monarch Plus RC3 is designed to offer the best combination of performance and adjustability. Here are the standout features:
- Three-Position Compression Adjustment: This allows riders to easily switch between different settings, enabling you to optimize performance for climbing, descending, and all-around riding.
- DebonAir™ Spring: The Monarch Plus RC3 utilizes the DebonAir™ spring system, which provides a more consistent feel throughout the stroke, ensuring smoother transitions between compression and rebound.
- RC3 Damping System: This high-performance damping system ensures better control and stability on rough terrain, enhancing traction and comfort.
- Adjustable Rebound Control: With the adjustable rebound feature, the shock offers more control over the spring’s return, preventing the rear wheel from bouncing excessively after compression.
- Durable and Lightweight Design: RockShox built the Monarch Plus RC3 with durability in mind, using high-quality materials that balance strength and weight.
Installation of the Monarch Plus RC3
Installing the Monarch Plus RC3 rear shock is a straightforward process but requires some basic tools and attention to detail. Below are the steps for proper installation:
Tools Required:
- Torque wrench [paid link]
- 8mm Allen wrench [paid link]
- Shock pump
- Grease (for mounting hardware)
Installation Steps:
- Remove the Old Shock (if applicable):
- Start by removing the existing rear shock from the bike frame. Use the 8mm Allen wrench [paid link] to remove the mounting bolts securing the shock to the frame.
- Prepare the New Monarch Plus RC3:
- Apply a small amount of grease to the mounting hardware to prevent corrosion.
- Ensure that the shock’s eyelet is correctly aligned with the frame’s mounting points.
- Install the Shock:
- Carefully insert the shock into the frame and secure it with the mounting bolts. Tighten the bolts to the manufacturer’s recommended torque specifications using a torque wrench [paid link].
- Set the Sag:
- Use a shock pump to set the initial air pressure in the Monarch Plus RC3. The recommended pressure varies depending on your weight and riding style. Start by inflating the shock to the appropriate pressure and check the sag (the amount of suspension compression when you sit on the bike).
- Recheck All Bolts:
- Double-check all bolts to ensure that everything is securely fastened before riding.
Adjusting the Monarch Plus RC3
Once installed, fine-tuning the Monarch Plus RC3 is essential for optimizing performance based on your riding preferences and terrain.
Compression Adjustment:
The Monarch Plus RC3 features a three-position compression switch that lets you adjust the shock’s compression. The three settings are:
- Open: Ideal for downhill or aggressive riding, providing maximum plushness and control over rough terrain.
- Pedal: Best for climbing or pedaling, offering a firmer setting to prevent excessive bobbing.
- Lock: Designed for smooth, flat terrain, the lockout setting eliminates any suspension movement, improving pedaling efficiency.
Rebound Adjustment:
The rebound adjuster allows you to control how quickly the shock returns after compression. If you experience too much bounce or instability, increase the rebound damping. If the rear wheel feels too sluggish after hitting bumps, decrease the rebound damping to allow for faster return.
Air Pressure:
Adjust the air pressure using a shock pump, based on your weight and preferred suspension feel. Higher air pressure results in a firmer shock, while lower pressure makes the shock feel more supple and responsive. Always check the sag to ensure proper setup.
Maintenance of the Monarch Plus RC3
Routine maintenance is crucial to keeping the Monarch Plus RC3 performing optimally. Here are some essential maintenance tips:
Regular Cleaning:
- Clean the shock after every ride to prevent dirt and debris from damaging the shock’s components. Use a damp cloth to wipe down the shock, especially the shaft and eyelets.
- Avoid using high-pressure water directly on the shock to prevent water from entering the internal components.
Lubrication:
- Apply a small amount of lubricant to the shock’s bushings to prevent wear and tear. This ensures smooth movement and helps avoid squeaking noises during rides.
Air Can Service:
- Every 50 hours of riding or once a season, perform a basic air can service. This involves removing the air sleeve, cleaning the seals, and adding fresh grease to ensure smooth movement and prevent air leaks.
Full Service:
- For optimal performance, it’s recommended to have a full service every 100 hours or annually. This includes inspecting the internal components, replacing any worn-out seals, and ensuring the shock functions correctly. Professional servicing is recommended for this process.
Troubleshooting Common Issues with the Monarch Plus RC3
Even the best components can experience issues over time. Here are some common problems and how to troubleshoot them:
1. Shock Losing Air Pressure:
- If the Monarch Plus RC3 consistently loses air, check for any visible damage or cuts to the air can. If none is visible, the issue may be due to a faulty valve or seal, which may need to be replaced.
2. Excessive Rebound or Bounce:
- If the rear wheel bounces excessively, it may be due to insufficient rebound damping or incorrect air pressure. Adjust the rebound settings and check the air pressure to ensure they are set correctly.
3. Compression Not Working Correctly:
- If the compression feels too soft or doesn’t engage in the pedal setting, check the compression knob and make sure it’s correctly adjusted. If the problem persists, the shock may need servicing.
4. Clunking Noise:
- A clunking noise can result from inadequate lubrication or worn bushings. Apply grease to the shock’s mounting points and check the bushings for wear. If necessary, replace them.
Customization and Optimization for Better Performance
To optimize the Monarch Plus RC3 for your specific riding needs, consider these customization tips:
Fine-Tune the Sag:
- The ideal sag is typically around 30% of the shock’s total travel. Adjust the air pressure until the shock compresses to the correct level under your weight. This ensures that the shock is neither too soft nor too stiff, providing the best performance.
Adjust the Compression for Terrain:
- On technical, rocky descents, use the “Open” setting for maximum control and comfort. For smoother, flatter terrain, you may prefer the “Pedal” or “Lock” settings to reduce unnecessary suspension movement.
Use a Shock Pump:
- Invest in a high-quality shock pump to make precise air pressure adjustments. This ensures that your suspension is dialed in for your body weight and riding style.
Compatibility with Other Drivetrain Components
The Monarch Plus RC3 rear shock is compatible with most modern mountain bike frames, including those with different suspension designs. However, it’s important to ensure that your frame is compatible with the shock’s mounting hardware and that the shock’s travel length matches your frame’s specifications.
For riders using specific drivetrain configurations, such as a 1x or 2x system, the compression settings and lockout feature of the Monarch Plus RC3 can help improve pedaling efficiency on smooth trails, making it a great choice for both technical and cross-country riding.
Conclusion
The Monarch Plus RC3 rear shock offers excellent performance and versatility for riders seeking a high-quality shock for aggressive trail riding and enduro events. With its adjustable settings, durable construction, and easy maintenance, it provides a smooth and customizable ride for cyclists of all levels. Whether you are looking to upgrade your current suspension or fine-tune your bike’s performance, the Monarch Plus RC3 is an excellent choice. By following the proper installation, adjustment, and maintenance guidelines, you can ensure that your shock delivers optimal performance for years to come.
