RockShox has long been a leader in the mountain biking suspension industry, and their Monarch R rear shocks are a key element of their renowned line-up. These rear shocks are designed to deliver outstanding performance, control, and comfort for a wide range of mountain biking disciplines. Whether you’re an experienced rider or a beginner looking to improve your bike’s suspension setup, understanding the Monarch R rear shock’s design and maintenance is essential for getting the most out of your bike.

Key Features and Design

The RockShox Monarch R is a high-performance rear shock designed to provide reliable damping and smooth suspension control. It features an air-sprung system that is adjustable to suit various riding styles and terrain conditions. One of the defining characteristics of the Monarch R is its simplicity combined with its effectiveness. It uses a straightforward single-air spring system along with a Rebound adjustment to fine-tune performance. The shock is also known for being lightweight, making it ideal for riders looking to reduce weight without compromising suspension quality.

Air Spring System

The air spring system in the Monarch R provides a progressive and adaptable ride, which makes it suitable for everything from cross-country to all-mountain riding. It ensures a smooth ride by adjusting the spring rate to match rider weight and riding conditions. This adaptability is crucial for maintaining optimal comfort and control over rough terrain.

Rebound Adjuster

The Monarch R includes a Rebound adjuster, which allows riders to adjust the speed at which the shock returns to its original position after compression. This feature is essential for maintaining stability and comfort during aggressive rides or when navigating technical terrain. A properly adjusted rebound helps prevent harsh “bouncing” after obstacles and ensures better control on the trail.

Installation of the Monarch R Rear Shock

Installing the Monarch R rear shock is a relatively straightforward process that requires the right tools and careful attention to detail. Follow these steps to install the Monarch R shock onto your bike:

Tools Required

• Torque wrench [paid link]
• 5mm and 6mm Allen wrenches [paid link]
• Shock pump
• Soft cloth or towel (to protect the shock and frame)
• Anti-seize grease (optional)

Installation Steps

1. Prepare the Bike: Ensure your bike is in a stable position, either in a bike stand [paid link] or flipped upside down. This will make the installation easier and prevent any accidental damage.
2. Remove the Old Shock (if applicable): If you’re replacing an old shock, use a 5mm Allen wrench [paid link] to remove the bolts attaching the shock to the frame. Be sure to keep the bolts, as you will likely reuse them for the new installation.
3. Install the Monarch R Shock: Position the Monarch R shock into the mounting location. Align the shock’s eyelets with the frame’s shock mounts, and insert the bolts to secure the shock in place. Tighten the bolts with a 6mm Allen wrench [paid link], ensuring they are torqued to the manufacturer’s recommended settings (usually around 150-175 inch-pounds).
4. Set the Sag: Use a shock pump to adjust the air pressure in the Monarch R shock. The proper air pressure is crucial for setting the correct “sag,” which is the amount the shock compresses under your body weight. For most riders, this will be around 25-30% of the total shock’s travel. You can check the sag by sitting on your bike in a riding position and observing how much the shock compresses.
5. Adjust Rebound: Fine-tune the rebound setting based on your preferences and riding conditions. Start with the rebound dial set to mid-range, and then adjust by turning it in either direction to speed up or slow down the rebound as needed.
6. Check for Smooth Operation: Before heading out for a ride, manually compress the shock to ensure smooth travel and that the suspension is working correctly. If it feels stiff or jerky, recheck the installation and air pressure.

Adjusting and Tuning the Monarch R Shock

The Monarch R is designed to be easy to adjust, allowing riders to fine-tune their suspension setup for optimal performance. Adjusting the shock to your weight, riding style, and terrain type can make a significant difference in your ride quality.

Air Pressure

The most important adjustment on the Monarch R rear shock is the air pressure. The shock’s performance is highly dependent on the correct air pressure, which should be adjusted according to the rider’s weight. To find the right air pressure, use a shock pump to gradually increase pressure and check the sag. Make small adjustments until you achieve the desired sag range of 25-30%.

Rebound Adjustment

The rebound control on the Monarch R is crucial for preventing “bouncing” during your ride. If the rebound is too fast, the shock will return too quickly, causing instability. On the other hand, if the rebound is too slow, the shock will struggle to return, potentially making the bike feel sluggish. Adjust the rebound by turning the dial on the shock, and test it by riding on varied terrain. Fine-tune until you find the setting that feels most comfortable and controlled.

Troubleshooting Common Issues

Although the Monarch R rear shock is designed for reliability, some common issues can arise that may require attention. Here’s how to troubleshoot these potential problems:

No Rebound Control

If you notice that the rebound control is not working or the shock is not returning to its normal position, the air pressure may be too low. Check and adjust the air pressure using a shock pump, ensuring it is within the recommended range for your weight.

Harsh Ride Quality

If the ride feels overly harsh or stiff, it might be due to excessive air pressure or improper sag. Check the sag and ensure it falls within the recommended range (around 25-30% of total travel). Adjust the air pressure as needed to ensure that the shock is properly set up for your weight.

Leaking Air

If you notice air loss from the shock, it could be due to damaged seals. Inspect the shock for any signs of wear or damage. If the shock continues to lose air, it may need to be serviced or re-sealed by a professional.

Customization for Optimal Performance

The Monarch R rear shock offers excellent customization options to suit various riders’ needs. In addition to adjusting the air pressure and rebound, there are several performance optimizations to consider:

Customizing Rebound

Adjusting the rebound to suit your riding style is one of the most important customizations you can make. For aggressive riders or those tackling rougher terrain, a slower rebound setting will help maintain control. For smoother, more flowy riding, a faster rebound may feel more responsive.

Fine-Tuning Air Pressure

Beyond the basic sag adjustment, some riders may want to experiment with different air pressures to fine-tune their ride. Lighter riders may prefer slightly lower air pressure for a softer feel, while heavier riders may opt for higher air pressure to prevent bottoming out during jumps or rough descents.

Comparison to Similar Models

When comparing the Monarch R rear shock to similar models, several factors come into play, such as weight, adjustability, and overall performance. Here’s how the Monarch R stacks up:

• Monarch R vs. Monarch RT3: The Monarch RT3 offers more advanced damping adjustments compared to the Monarch R. While the Monarch R features a straightforward Rebound adjustment, the RT3 includes additional compression adjustments, making it more suitable for riders who want to fine-tune the shock’s performance for different terrain types.
• Monarch R vs. Fox Float Performance: The Fox Float Performance shock is another popular option in the rear suspension category. While both shocks offer excellent performance, the Monarch R is known for being slightly lighter and more user-friendly, making it a great choice for riders seeking simplicity without sacrificing performance.

Compatibility with Other Drivetrain Components

The Monarch R rear shock is designed to be compatible with a wide range of mountain bike frames and drivetrains. It is essential to ensure that the shock’s travel and mounting system align with your bike frame’s requirements. Additionally, the air pressure should be adjusted in conjunction with your bike’s overall setup, including fork settings and tire pressures, for the most balanced performance.

When upgrading or replacing a rear shock, always double-check compatibility with the frame and other suspension components to avoid setup issues.
