Tools Required

  • Shock pump
  • 5mm Allen wrench [paid link]
  • 10mm socket wrench
  • Torque wrench [paid link]
  • Suspension fluid (RockShox recommended)
  • Clean rags
  • Isopropyl alcohol (for cleaning)
  • RockShox rebound and compression adjustment tool (if necessary)
  • Grease (light)

Installation of the Monarch R Rear Shock

The installation of your RockShox Monarch R rear shock is straightforward but requires careful attention to detail. Follow these steps to ensure a proper fit and alignment.

  1. Prepare the Frame: Clean the mounting areas on both the frame and shock with a rag and isopropyl alcohol to remove any dirt or grease that might affect the installation.
  2. Position the Shock: Align the eyelet and mounting hardware of the Monarch R with the frame’s suspension mount. Ensure that the shock is correctly oriented—typically, the damper side should face the rear of the bike.
  3. Install the Shock: Using the 5mm Allen wrench [paid link], insert the mounting bolts into the frame and tighten them securely. Be careful not to overtighten, as this may cause damage to the shock or frame. A torque wrench [paid link] set to the recommended value for the frame’s shock mounts is ideal.
  4. Secure the Shock: Tighten the bolts using a torque wrench to the manufacturer’s recommended torque setting. Typically, this is around 8-10 Nm but always refer to the specific bike frame manual for exact values.
  5. Check Alignment: Ensure the shock is mounted in a straight line and is not under tension. Double-check that all bolts are securely fastened.

Adjusting the Monarch R Rear Shock

Proper adjustments to the Monarch R rear shock allow for better performance and comfort depending on your riding style and terrain. The shock features air pressure adjustments for the spring rate, along with rebound and compression damping controls.

Rebound Adjustment

The rebound controls how quickly the shock returns to its original position after being compressed.

  1. Locate the Rebound Dial: The rebound dial is located at the bottom of the shock body.
  2. Set the Rebound: Turn the dial clockwise to slow down the rebound (ideal for rougher terrain) or counterclockwise to speed it up (ideal for smoother trails). Start with the rebound set to the middle and adjust from there based on the trail conditions.

Air Pressure Adjustment

Adjusting the air pressure in the Monarch R affects the shock’s spring rate and the overall support it provides.

  1. Measure Your Rider Weight: Use a shock pump to inflate the shock to a recommended starting air pressure. This is usually based on your rider weight and riding style. You can find suggested air pressure settings in the Monarch R user manual.
  2. Fine-Tune the Pressure: Inflate or deflate the shock incrementally, checking the sag. To check sag, sit on your bike and measure the compression of the shock. Ideally, the shock should compress about 25-30% of its total stroke when you’re in riding position.

Compression Adjustment

The Monarch R rear shock offers adjustable compression damping, allowing you to fine-tune how much resistance the shock provides when compressing.

  1. Locate the Compression Dial: The compression dial is typically located at the top of the shock.
  2. Adjust Compression: Turn the dial to increase compression (ideal for rough or technical trails) or reduce it for smoother, less challenging terrain. Start with the middle setting and adjust based on your preference.

Regular Maintenance of the Monarch R

Routine maintenance of your Monarch R rear shock ensures it performs well throughout the riding season. Performing these steps regularly will also extend the lifespan of your shock.

Cleaning the Shock

Regularly clean your Monarch R shock to prevent dirt and grime from accumulating in the seals and affecting its performance.

  1. Clean the Shock Body: Wipe down the shock with a clean rag after each ride, particularly around the air can and seals.
  2. Check for Leaks: Inspect the shock for any signs of oil leakage or wear around the seals. If you notice any leakage, the shock may require servicing or seal replacement.

Servicing the Shock

After a set number of riding hours or at least once a season, it’s recommended to perform a full service on the Monarch R.

  1. Disassemble the Shock: If you’re comfortable with servicing your shock, you can remove the air can and damper. Be sure to have the appropriate tools, such as a seal driver and damper shaft tool, to avoid damaging components.
  2. Lubricate and Replace Seals: Apply light grease to the shock components and replace any worn-out seals. Reassemble the shock carefully, making sure all parts are seated properly.
  3. Oil Changes: Change the internal suspension fluid if necessary. Follow RockShox’s guidelines for fluid types and amounts to ensure proper shock performance.

Troubleshooting Common Issues

While the Monarch R rear shock is durable, you may encounter some common issues during use. Below are some troubleshooting tips to help resolve these issues.

Poor Rebound Performance

If the shock rebounds too quickly or slowly, check the rebound adjustment first. If the adjustment does not seem to help, there may be an issue with the damper oil or internal seals.

Air Pressure Loss

If the shock loses air pressure over time, it could be due to a leak in the air spring or seals. Inspect the shock for visible damage and consider performing a seal replacement if necessary.

Noisy Shock

A noisy shock may be caused by a lack of lubrication, dirt in the shock body, or damaged seals. Cleaning the shock thoroughly and applying lubrication should resolve most noise issues.

Customizing and Optimizing Performance

The Monarch R rear shock is designed to provide a customizable ride, so you can fine-tune its performance to suit different riding styles and terrain types. Here are a few tips to optimize the shock’s settings:

  • For Cross-Country Riding: Opt for a higher air pressure setting to maintain efficiency and responsiveness over smooth terrain.
  • For Downhill Riding: Lower the air pressure and slow the rebound for a more controlled, plush feel that handles bigger hits and rougher trails.
  • For Enduro Riding: A balanced setting with medium air pressure and rebound adjustment works well for mixed terrain.

Comparison with Similar Models

When comparing the Monarch R to other rear shocks from RockShox, such as the Deluxe and Super Deluxe, the Monarch R stands out for its simplicity and reliability at a competitive price point. It offers adjustable rebound and compression, but lacks the advanced tuning options and larger air can found in higher-end models like the Super Deluxe. If you’re an experienced rider seeking ultimate performance and adjustability, you may prefer the Super Deluxe. However, for everyday riders who prioritize ease of use and cost-effectiveness, the Monarch R is an excellent choice.

Compatibility with Other Drivetrain Components

The Monarch R rear shock is designed to work seamlessly with a variety of modern mountain bike frames and drivetrains. However, it’s essential to ensure compatibility in terms of the shock’s eyelet size and the frame’s mounting system. Most modern bikes using a standard 200mm eyelet or a custom configuration will work well with the Monarch R, but always check the manufacturer’s specifications for compatibility with your bike’s geometry and suspension setup.

By following these guidelines, you can ensure that your Monarch R rear shock performs at its best for every ride. Regular maintenance, thoughtful adjustments, and troubleshooting will allow you to get the most out of your suspension system, giving you a smooth and controlled riding experience every time you hit the trails.
