The Monarch Plus RC3 is a high-performance rear shock designed by RockShox, a trusted brand in the cycling industry. It is known for its reliability, adjustable features, and excellent handling in various riding conditions. This guide will dive deep into the installation, maintenance, adjustment, troubleshooting, and performance optimization of the Monarch Plus RC3 rear shock, along with its compatibility with other drivetrain components. Whether you are a beginner or an experienced cyclist, this article provides all the necessary information to maximize the performance and lifespan of your rear shock.

Installation of the Monarch Plus RC3 Rear Shock

The Monarch Plus RC3 rear shock is designed for easy installation, but it requires precision and careful attention to detail to ensure optimal performance.

Step-by-Step Installation Guide

1. Prepare the Bike Frame:
   • Ensure that the rear triangle of your bike is free of dirt and debris.
   • Remove any existing shock if necessary by unscrewing the mounting bolts at both the top and bottom eyelets.
2. Mounting the Shock:
   • Align the shock with the mounting eyelets on the bike frame. Ensure the shock’s mounting hardware (bushings) fits properly into the frame.
   • Tighten the bolts at both the top and bottom of the shock, being careful not to overtighten. A torque wrench [paid link] should be used to apply the manufacturer-recommended torque value.
3. Verify Proper Alignment:
   • Double-check the alignment of the shock to avoid any binding during the suspension’s movement.
   • Ensure the shock’s stroke length matches the bike frame’s specifications to prevent excessive compression.
4. Final Check:
   • Test the shock by manually compressing it and checking for smooth movement.
   • Verify the position of the shock’s rebound and compression settings for optimal riding performance.

Adjustment of the Monarch Plus RC3 Rear Shock

One of the standout features of the Monarch Plus RC3 is its highly customizable damping system. With three adjustable settings for compression and rebound, the shock can be tailored to suit various riding conditions.

Adjusting Compression Settings

The Monarch Plus RC3 features the Open, Pedal, and Lockout modes for compression adjustment. Each mode is suitable for different riding conditions.

• Open Mode: Ideal for rough, technical terrain where you need maximum shock absorption.
• Pedal Mode: Provides a more efficient ride on smoother surfaces by reducing the amount of shock movement.
• Lockout Mode: Completely stiffens the shock for minimal movement, best for climbing or smooth roads.

To adjust the compression, turn the large dial on the shock’s body. Rotate the dial clockwise for firmer compression (Pedal or Lockout modes) and counterclockwise for softer compression (Open mode).

Adjusting Rebound Settings

The rebound adjustment controls the speed at which the shock returns after compression. Too fast, and the shock may cause bouncy, uncontrollable behavior. Too slow, and it may cause the shock to pack down under successive impacts.

• Turn the rebound dial clockwise to slow the rebound, which is useful for aggressive downhill riding.
• Turn the rebound dial counterclockwise to increase the rebound speed, helping to maintain control on smoother trails.

Start with the rebound setting at the middle position and adjust based on your riding style and terrain.

Maintenance of the Monarch Plus RC3 Rear Shock

Regular maintenance ensures that the Monarch Plus RC3 remains in top working condition for years. It is essential to perform routine checks and servicing to prolong the lifespan of your shock.

Routine Checks

• Inspect for Leaks: Check the shock’s seals and body for any signs of oil leakage. If leaks are found, it may be time to replace the seals or send the shock for service.
• Clean the Shock: After every ride, wipe down the shock with a clean cloth to remove dirt and debris. Use a gentle degreaser if necessary, but avoid using harsh chemicals that could damage the shock’s finish.
• Check Mounting Bolts: Ensure that the mounting bolts are tight and in good condition. Loose bolts can lead to improper shock function and potential damage to the frame.

Full Servicing

For a full shock service, it is recommended to send the Monarch Plus RC3 to an authorized RockShox service center. A complete overhaul involves replacing seals, oil, and bushings, ensuring that the shock performs like new. It is recommended to service the shock every 50 to 100 hours of riding, depending on the severity of usage.

Troubleshooting Common Set-Up Issues

While the Monarch Plus RC3 is a reliable rear shock, certain issues may arise, particularly during setup or usage. Here are some common problems and their solutions.

Problem: Shock Not Compressing Smoothly

Solution:

• Check for any dirt or debris in the shock’s eyelets or seals that may be impeding smooth movement.
• Verify that the correct volume of air has been pumped into the shock. Insufficient air pressure can result in inadequate shock compression.
• Inspect the shock’s internal components for wear or damage if the problem persists.

Problem: Rebound Too Fast or Too Slow

Solution:

• Adjust the rebound dial to find a setting that suits your riding style. For technical terrain, a slower rebound is recommended.
• If the rebound is still not functioning correctly, the shock may need to be serviced to address internal issues.

Problem: Loss of Air Pressure

Solution:

• If you notice a drop in air pressure, inspect the shock’s valve for leaks. Tighten or replace the valve if necessary.
• Check the air spring chamber for damage. If there is significant pressure loss, consider servicing the shock to replace damaged parts.

Customization and Optimization for Better Performance

The Monarch Plus RC3 can be further optimized for better performance through a few simple adjustments. By customizing the shock to suit your riding style and terrain, you can achieve a smoother, more controlled ride.

Air Pressure Optimization

Adjusting the air pressure in the shock’s positive and negative air chambers can drastically change the ride quality. For aggressive riders, increasing the air pressure can prevent bottoming out on jumps and rough trails. Conversely, lower air pressure can improve comfort on smoother trails.

• Start by setting the air pressure according to the rider weight chart provided by RockShox.
• Fine-tune the pressure after a few rides to adjust for personal preference, balancing comfort and control.

Volume Spacers

The Monarch Plus RC3 allows the addition of volume spacers, which change the shock’s progression throughout its stroke. Adding spacers can make the shock feel firmer in the latter half of the stroke, providing more bottom-out resistance for aggressive riders.

• If you’re bottoming out on large drops or rough terrain, consider adding a spacer to increase progression.
• If you prefer a more plush ride, removing a spacer can make the shock feel softer and more active.

Compatibility with Other Drivetrain Components

The Monarch Plus RC3 rear shock is compatible with most modern mountain bikes and features an adjustable eyelet for easy installation with different frame designs. However, it’s essential to verify the shock’s dimensions and eyelet sizes with your bike’s specifications before purchasing.

• Shock Length and Stroke: Ensure the shock’s length and stroke match your bike’s suspension geometry. A mismatched shock can lead to poor handling and even damage the frame.
• Mounting Hardware Compatibility: The Monarch Plus RC3 uses standard mounting hardware, but some bikes may require specific hardware to achieve the correct fit. Always check compatibility before installation.

When paired with high-performance drivetrain components like SRAM or Shimano, the Monarch Plus RC3 provides excellent shock absorption and optimal performance. It helps maintain control during technical climbs and descents, complementing the responsiveness of the drivetrain.

Comparison with Similar Models

Compared to other rear shocks in its category, the RockShox Monarch Plus RC3 stands out due to its advanced damper technology and versatile adjustability. Other models like the Fox Float DPX2 and the Cane Creek Double Barrel are also popular choices, but the Monarch Plus RC3 tends to offer more tunability and a smoother, more controlled ride.

• Fox Float DPX2: Known for its progressive damping and high performance, but may lack the versatility in compression settings found in the Monarch Plus RC3.
• Cane Creek Double Barrel: Offers more advanced tuning options but comes at a significantly higher price point, making the Monarch Plus RC3 a more affordable and competitive choice.

Ultimately, the Monarch Plus RC3 is a reliable, high-quality shock that offers excellent value for money, especially for riders who want a smooth ride on diverse terrains without breaking the bank.
