The Monarch Plus RC3 Rear Shock from RockShox is a high-performance shock designed to provide an exceptional ride experience on a variety of terrain. Whether you’re tackling technical descents, aggressive climbs, or smooth cross-country trails, this shock optimizes comfort and control, ensuring that your bike performs at its best. In this detailed guide, we’ll cover everything you need to know about installing, adjusting, maintaining, and troubleshooting the Monarch Plus RC3, as well as comparing it with other shocks to help you decide if it’s the right choice for your bike.
Key Features of the Monarch Plus RC3
The Monarch Plus RC3 Rear Shock is packed with features that enhance the overall ride quality of your bike. These include:
- Dual Flow Adjust: This feature provides separate compression adjustments for both the high-speed and low-speed circuits, giving you better control and adaptability across different types of terrain.
- Rebound Adjust: The rebound control helps to regulate the shock’s return rate, allowing for a smooth and controlled ride even on rough surfaces.
- Solo Air Spring: This system makes it easy to adjust the air pressure for your preferred ride feel, ensuring that the shock suits different rider weights and riding styles.
- Lightweight Design: Despite its robust performance, the Monarch Plus RC3 is designed to keep your bike’s weight in check, which is especially beneficial for riders who require optimal control without added bulk.
Installation of the Monarch Plus RC3 Rear Shock
Proper installation is essential for ensuring that the Monarch Plus RC3 Rear Shock functions at its peak performance. Follow these steps carefully to install it:
- Prepare the bike: Make sure the bike is secure in a workstand to keep it stable during installation.
- Remove the old shock (if applicable): Use the appropriate tools to detach the previous shock from the frame. Ensure you have the correct size Allen wrenches [paid link] or torque wrenches.
- Position the new shock: Align the Monarch Plus RC3’s eyelets with the frame’s mounting points. Ensure the shock is oriented correctly to avoid any clearance issues.
- Secure the shock: Tighten the mounting bolts with the appropriate torque to avoid damaging the frame or shock. Use a torque wrench [paid link] to ensure the proper tightness, usually between 200-300 in-lbs, depending on the manufacturer’s specifications.
- Install the shock’s air valve: Attach the air pump to the shock’s valve and set the air pressure according to your weight and riding style. RockShox provides a suggested air pressure chart for reference.
Adjustment and Customization for Optimal Performance
The Monarch Plus RC3 offers several ways to fine-tune your ride. Here’s how you can adjust the shock for better performance:
Compression Adjustment
- Low-Speed Compression: This controls the shock’s response to slow-moving impacts, such as when riding over rocks or roots. Turn the knob to adjust it based on the terrain you’ll be riding. For smoother trails, you can reduce the low-speed compression for a softer feel. For more aggressive terrain, increase it for better stability and control.
- High-Speed Compression: This affects the shock’s response to fast impacts, such as drops or larger hits. A higher setting will provide better support for big impacts, while a softer setting is more forgiving.
Rebound Adjustment
The rebound setting controls how quickly the shock returns after compressing. To set it up properly, adjust the knob to ensure the shock doesn’t return too quickly or too slowly. For smoother terrain, a faster rebound is often preferred, while a slower rebound is better for more technical or aggressive riding.
Air Pressure Adjustment
- Adjusting the air pressure is essential for achieving the desired ride feel. Refer to the chart provided by RockShox, which suggests specific pressures based on rider weight. Be sure to set the air pressure accordingly, considering factors such as riding style and terrain.
- Remember to periodically check air pressure as it can change with temperature fluctuations.
Troubleshooting Common Set-Up Issues
Lack of Plushness or Comfort
If you find that the Monarch Plus RC3 isn’t providing the plush feel you expected, this could be due to insufficient air pressure. Ensure that you have the right air pressure for your weight and riding style. Additionally, check the low-speed compression setting; too much compression can result in a stiff ride.
Rebound Problems
If the shock is either too slow to return or too fast, this could be due to improper rebound setting or air pressure. Adjust the rebound knob accordingly, and verify the air pressure again. If the problem persists, inspect the shock for any potential damage or wear.
Noisy Shock
If you notice unusual noises coming from the shock during use, check for dirt or debris around the shock’s eyelets. Cleaning the shock and lubricating the mounting points can often solve this issue. Also, check for proper shock installation to ensure everything is tightened to the correct torque.
Maintenance of the Monarch Plus RC3
Regular maintenance is crucial for keeping your Monarch Plus RC3 rear shock in optimal condition. Here’s how to maintain it:
- Clean the shock: After each ride, clean the shock using a soft cloth to wipe away dirt and grime. Pay special attention to the area around the eyelets and the air valve.
- Inspect for wear: Look for any signs of wear or damage, such as oil leakage or cracks in the shock body. If you notice any issues, take the shock to a professional mechanic for servicing.
- Re-oil the shock: Over time, the shock’s internal oil can degrade. If you ride in harsh conditions or frequently use the shock’s full range of travel, you may need to service the shock. RockShox recommends a professional service every 50-100 hours of use.
Comparison with Other Rear Shocks
When comparing the Monarch Plus RC3 to other rear shocks in the market, especially within the RockShox lineup, the main advantage lies in its versatility and adjustability.
- Monarch Plus RC3 vs. Super Deluxe: The Super Deluxe is another high-performance shock from RockShox but typically offers more advanced features like a better damper and more precise adjustments. However, the Monarch Plus RC3 offers a more budget-friendly option without compromising on core performance, making it a great choice for riders who want excellent value for their investment.
- Monarch Plus RC3 vs. Fox Float X2: The Fox Float X2 is known for its plush feel and incredible performance, particularly in aggressive riding conditions. However, it is generally more expensive and heavier than the Monarch Plus RC3. The Monarch Plus RC3, on the other hand, provides a similar level of performance with a lighter weight and more accessible price point, making it ideal for trail riders who don’t need the extreme capabilities of the Float X2.
Compatibility with Other Drivetrain Components
The Monarch Plus RC3 is compatible with a wide range of modern mountain bike frames and drivetrains. However, it is important to check the specific frame dimensions and shock specifications to ensure compatibility. The shock uses standard mounting eyelets, making it compatible with most modern mountain bikes that utilize a rear shock. Always verify your bike frame’s specifications, including shock length and stroke, to confirm the Monarch Plus RC3’s fit.
With its comprehensive adjustment options and robust build, the Monarch Plus RC3 enhances ride quality across a broad spectrum of mountain biking disciplines. Whether you’re seeking comfort on long rides or control on aggressive descents, this shock can be customized to meet your needs, delivering a smoother, more responsive ride.
