The Monarch RT3 from RockShox is a popular rear shock among mountain bikers due to its impressive performance and advanced technology. However, when considering a rear shock upgrade or replacement, it’s important to compare it to similar models on the market to ensure you’re making the right choice for your riding style and needs. In this article, we’ll dive into the installation, adjustment, and maintenance of the Monarch RT3, troubleshoot common setup issues, explore ways to optimize performance, and compare it to competing models to help you choose the best rear shock for your bike.

Installation of the Monarch RT3 Rear Shock

Installing the Monarch RT3 is straightforward but requires a few careful steps to ensure optimal performance. Here’s how to properly install this rear shock on your bike.

1. Remove the old shock: Before installing the Monarch RT3, you’ll need to remove the existing rear shock. This typically involves removing the bolts that secure the shock to the frame. Make sure you keep track of any spacers or washers that come off with the shock, as they might be reused.
2. Check compatibility: Verify that the Monarch RT3 is compatible with your bike’s frame. It comes in various sizes and eye-to-eye lengths, so ensure the shock matches your bike’s geometry. The RT3 features a standard mounting system, but double-check that it fits within your frame’s shock mount.
3. Install the new shock: Insert the Monarch RT3 into the shock mount on the bike frame. Secure it by tightening the mounting bolts to the recommended torque specifications. Avoid overtightening, as this can cause damage to the shock or frame.
4. Double-check alignment: Ensure the shock is properly aligned and does not have any undue strain on the mounting points. The shock should move freely without interference from any other components.

Adjusting the Monarch RT3 Rear Shock

The Monarch RT3 offers a high level of customization, allowing you to fine-tune the shock to your specific riding needs. Here’s how to adjust it for optimal performance.

Rebound Adjustment

The Monarch RT3 features a rebound adjustment knob located at the bottom of the shock. This knob allows you to control the speed at which the shock returns to its original position after compression.

• Turning the knob clockwise slows down the rebound, ideal for smoother terrain or heavier riders.
• Turning the knob counterclockwise speeds up the rebound, which can be beneficial for lighter riders or faster terrain.

Compression Adjustment

The RT3 has a three-position compression adjuster: Open, Pedal, and Lock. This feature allows you to adjust the shock’s compression depending on the type of terrain you’re riding.

• Open: Provides maximum compression and allows for better handling on rough terrain.
• Pedal: Provides medium compression, reducing pedal bob for more efficient pedaling on smoother trails.
• Lock: Fully locks the shock for maximum efficiency during climbs or when riding on smooth terrain.

Air Pressure

To adjust the air pressure in the Monarch RT3, use a shock pump. The recommended air pressure will depend on the rider’s weight and the specific riding style. Typically, air pressure should be set based on your weight and the shock’s recommended range. You can refer to the Monarch RT3’s manual for specific pressure recommendations based on your weight.

Maintaining the Monarch RT3 Rear Shock

Proper maintenance is key to keeping the Monarch RT3 functioning smoothly over time. Regular maintenance ensures longevity and reliability.

1. Clean the shock regularly: Dirt and debris can accumulate on the shock body, which could cause damage to the seals. Wipe down the shock with a soft cloth after each ride, paying special attention to the stanchions and seals.
2. Check air pressure: Over time, the air pressure in the shock can decrease. Check and adjust the air pressure periodically to ensure optimal performance.
3. Lubricate seals: Apply a small amount of shock-specific lubricant to the seals to reduce friction and prevent wear. This will also help prevent leaks.
4. Annual service: While the Monarch RT3 is designed for durability, it’s a good idea to have it serviced annually by a professional mechanic to ensure the internal components are in good working order.

Troubleshooting Common Setup Issues

Despite the Monarch RT3’s advanced design, issues can arise during setup or use. Here are a few common problems and their solutions:

Problem 1: Shock feels too soft

• Solution: If the shock feels too soft, you may need to increase the air pressure. Check the recommended pressure for your weight and adjust accordingly using a shock pump. If you’re riding rough terrain, you may also want to increase the rebound speed.

Problem 2: Shock feels too stiff

• Solution: If the shock feels too stiff, try decreasing the air pressure slightly. You can also adjust the compression setting to the “Open” position for better absorption of bumps and obstacles.

Problem 3: No rebound or slow rebound

• Solution: If the shock is not rebounding or feels too slow, check the rebound adjustment knob. Turn it counterclockwise to speed up the rebound. If it still doesn’t respond, you may need to check for internal damage or take the shock for servicing.

Optimizing Performance of the Monarch RT3

To get the best performance out of your Monarch RT3, consider the following optimization tips:

• Adjust air pressure for riding style: Lighter riders may require less air pressure, while heavier riders will need more. Fine-tune the air pressure according to your weight and riding style for the best performance.
• Set compression damping for terrain: Use the compression adjuster to dial in the suspension for the type of terrain you’ll be riding. For aggressive downhill riding, the “Open” position offers the best performance, while the “Pedal” setting helps reduce bobbing on flatter trails.
• Rebound tuning: Experiment with the rebound knob to find the optimal setting that suits your riding style. Too fast a rebound can result in a bouncy ride, while too slow can cause the shock to pack down and lose its ability to absorb bumps.

Comparing Monarch RT3 to the Competition

When choosing a rear shock, it’s important to consider your options. The Monarch RT3 has a solid reputation, but how does it compare to other models in the market? Here are some of its key competitors and how they stack up:

1. Fox Float DPS

The Fox Float DPS is another popular rear shock known for its smooth performance and tunability. Compared to the Monarch RT3, the Fox Float DPS offers more adjustability, including a larger number of compression settings. However, the Monarch RT3 is typically lighter and offers a slightly better value for the price.

2. DT Swiss M210

The DT Swiss M210 is a versatile rear shock that excels in performance across a variety of terrains. While the M210 offers great durability and smoothness, the Monarch RT3 provides slightly better performance for aggressive riders due to its more advanced damping technology.

3. RockShox Deluxe R

The RockShox Deluxe R shares many similarities with the Monarch RT3 in terms of features and performance, but it is designed for a more budget-conscious rider. The Monarch RT3 offers slightly more adjustability and higher-end internals for riders looking for fine-tuned control over their ride.

Compatibility with Other Drivetrain Components

The Monarch RT3 is compatible with most modern drivetrain systems. It integrates seamlessly with both SRAM and Shimano drivetrains. However, it’s important to check your bike’s rear triangle geometry to ensure the shock will work with your frame and other suspension components.

For optimal performance, always make sure that your rear shock’s air pressure and rebound settings complement your bike’s drivetrain for maximum efficiency. Additionally, pairing the Monarch RT3 with compatible suspension forks from RockShox can provide a more balanced and responsive ride.
