The Monarch R rear shock by RockShox is a highly regarded component in the world of mountain biking and off-road cycling. Known for its durability, smooth performance, and straightforward design, the Monarch R is ideal for riders seeking a reliable and affordable rear shock. In this guide, we’ll explore everything you need to know about installing, maintaining, and optimizing this shock, as well as comparing it to other models in its class.

Installation of the Monarch R Rear Shock

Mounting the Shock

The installation process for the Monarch R rear shock is fairly straightforward, especially with RockShox’s user-friendly design. Here’s a step-by-step guide to mounting the shock on your frame:

  1. Prepare the Bike Frame: Ensure your bike’s rear triangle is clean and free of debris. This is essential to avoid damaging the shock or frame during installation.
  2. Remove the Old Shock (if applicable): Use a 5mm Allen wrench [paid link] to remove the bolts securing the old shock to the frame. Keep these bolts for installing the Monarch R, unless the shock comes with new hardware.
  3. Align the Shock: Carefully align the eyelets of the Monarch R with the mounting hardware on the frame. RockShox rear shocks typically use eyelet-based mounting, so ensure the bushings are properly placed.
  4. Install the Bolts: Use the provided bolts or your original hardware to secure the shock in place. Tighten them with a torque wrench [paid link] to the recommended torque settings (usually around 200-250 inch-pounds, but refer to the specific model’s manual).
  5. Check for Clearance: Before tightening everything down fully, check that the shock has adequate clearance for the frame and the linkage. Ensure the shock moves smoothly without obstruction.
  6. Test the Shock: Once installed, perform a quick suspension test. Gently compress and release the shock to ensure proper mounting and function.

Setting the Sag

Setting the correct sag (the amount of suspension compression when the rider is on the bike) is crucial for optimal performance. For the Monarch R, RockShox recommends a sag of around 15-20% of the shock’s total travel. To set the sag:

  1. Measure Rider Weight: Ensure the rider is fully geared up, as weight impacts sag.
  2. Adjust the Air Pressure: Using a shock pump, adjust the air pressure to the rider’s weight. Start with a moderate setting and test ride.
  3. Check the Sag: Sit on the bike and measure how much the shock compresses. Adjust the air pressure if necessary.

Maintenance and Care of the Monarch R

Routine maintenance is crucial to keep the Monarch R rear shock performing at its best. Here’s a general overview of maintenance tasks for longevity and optimal function:

Cleaning and Lubrication

  1. Regular Cleaning: Clean the shock after each ride, especially if you’ve ridden in muddy or wet conditions. Use a damp cloth to wipe down the shock body, and avoid using harsh chemicals or abrasives.
  2. Lubrication: Apply lubricant to the shock’s stanchion periodically, as this will reduce friction and prevent wear on the seals. Make sure to use a lubricant designed for suspension components to avoid damaging the seals.

Air Spring Maintenance

The Monarch R features an air spring, which requires periodic checks for optimal performance:

  1. Check Air Pressure Regularly: Use a shock pump to maintain proper air pressure in the shock. Variations in temperature and altitude can cause fluctuations in air pressure, so it’s important to check before each ride.
  2. Seal Care: Over time, the air seals can wear out. It’s recommended to replace the seals every 50-100 hours of riding, depending on your riding conditions.

Full Suspension Service

  1. Annual Service: RockShox recommends servicing the Monarch R rear shock at least once a year. This service includes oil changes and a complete inspection of the internal components.
  2. DIY Service or Professional Help: While some tasks like air pressure adjustment can be done at home, it’s best to take your shock to a professional for a full service. This ensures the internals are checked, and any worn-out parts are replaced.

Troubleshooting Common Set-up Issues

Even though the Monarch R is relatively low-maintenance, there are a few common issues that riders may encounter during use. Here’s how to address some typical problems:

Lack of Rebound or Compression

  • Possible Cause: The rebound or compression adjuster may be incorrectly set, or the shock may need more air pressure.
  • Solution: Double-check the settings for rebound and compression. If the shock is too stiff or too soft, adjust the air pressure and fine-tune the damping.

Noisy Shock

  • Possible Cause: A noisy shock can occur if there is insufficient lubrication or dirt is interfering with the shock’s movement.
  • Solution: Clean the shock and apply a light coating of lubricant to the stanchion. If the noise persists, inspect the shock’s seals and replace them if necessary.

Bottoming Out

  • Possible Cause: If the shock is bottoming out (compressing all the way), the air pressure may be too low or the rebound setting might be too fast.
  • Solution: Increase the air pressure to accommodate the rider’s weight. Also, check the rebound setting to ensure the shock isn’t compressing too quickly.

Customization and Optimization for Better Performance

The Monarch R rear shock can be fine-tuned for different riding styles and terrain. Here are some customization options to get the most out of your shock:

Adjusting Rebound and Compression

  • Rebound Adjustment: The Monarch R features an external rebound adjuster, allowing riders to control the speed at which the shock returns to its normal position after compression. For aggressive riding, set a slower rebound to prevent the shock from bouncing back too quickly.
  • Compression Adjustment: While the Monarch R doesn’t have a separate high-speed compression adjustment, the low-speed compression can be modified to improve the shock’s response to different trail conditions.

Tuning for Specific Riding Styles

  • Cross-Country (XC): For XC riders, set the shock to a firm compression setting with a quicker rebound to improve pedaling efficiency and reduce energy loss.
  • Trail Riding: Set the shock to a more moderate compression setting, allowing for better bump absorption on technical trails. A slower rebound setting can improve control when descending.

Comparison with Similar Models

When comparing the Monarch R with other shocks in its category, such as the Fox Float DPS or RockShox Deluxe, several key differences stand out:

  • Monarch R: Known for its simplicity and affordability, it is a great option for riders who don’t need extensive adjustability but still want a reliable and smooth ride.
  • Fox Float DPS: Offers more adjustability with a high-speed compression option, which is ideal for riders who want a more tailored suspension experience.
  • RockShox Deluxe: Slightly higher-end than the Monarch R, offering similar features but with additional adjustability for both low- and high-speed compression and rebound, making it more suitable for aggressive riding.

Compatibility with Other Drivetrain Components

The Monarch R rear shock is designed to work seamlessly with a wide range of mountain bike frames, particularly those with a linkage-driven suspension system. It’s essential to check the shock’s eyelet size and mounting hardware compatibility with your bike’s frame. Additionally, because the Monarch R is a rear shock, it doesn’t directly interact with drivetrain components, but it’s still important to ensure the suspension works in harmony with your bike’s geometry and riding style.
