Installation of the Monarch R Rear Shock

Installing the RockShox Monarch R rear shock is straightforward, but proper alignment and torque specifications must be followed to ensure optimal performance and safety.

Tools Required

• Torque wrench [paid link] (for precise torque specifications)
• Shock pump (to adjust air pressure)
• 5mm Allen wrench [paid link]
• 8mm or 10mm socket wrench (depending on hardware)
• Grease (optional for mounting hardware)

Step-by-Step Installation Process

1. Remove the Old Shock: Use an 8mm or 10mm socket wrench to loosen the mounting bolts securing your old shock. Keep the mounting hardware for reuse, if compatible with the new shock.
2. Clean the Mounting Area: Clean the frame’s shock mounts thoroughly. Apply a small amount of grease to prevent creaking and ensure a smooth fit.
3. Install the Monarch R Shock: Slide the Monarch R shock into place, aligning the mount holes with the shock hardware. Tighten the bolts to the manufacturer-recommended torque specification (usually around 8-10Nm).
4. Set Air Pressure: Use a shock pump to set the air pressure based on your rider weight. Refer to the pressure chart provided by RockShox for optimal settings.
5. Check for Proper Fit: Ensure that the shock sits securely and moves freely without interference from the frame or other components.

Adjusting the Monarch R Rear Shock for Optimal Performance

Fine-tuning your Monarch R rear shock is crucial to ensure it performs at its best based on your weight, riding style, and terrain.

Rebound Damping Adjustment

The Monarch R features a simple rebound adjustment knob located at the bottom of the shock. This adjustment controls how quickly the shock returns to its original position after compressing.

• Turning the knob clockwise increases rebound damping, slowing down the return stroke. This is useful for rougher terrain where faster compression and slower rebound are necessary.
• Turning the knob counterclockwise decreases rebound damping, allowing for a faster return. This setting is beneficial when riding smoother trails or for riders who prefer a more lively feel.

Air Pressure Adjustment

The air pressure inside the Monarch R determines the shock’s responsiveness and overall comfort. To adjust air pressure:

• Start by referring to the RockShox pressure chart based on your rider weight.
• Use the shock pump to increase or decrease air pressure as needed. Typically, higher air pressure is better for heavier riders, while lighter riders may prefer a softer setting.
• Make small adjustments and test ride your bike to find the most comfortable setting.

Maintenance and Longevity of the Monarch R

Maintaining the Monarch R rear shock is essential for preserving its performance and extending its lifespan. Regular cleaning, inspection, and servicing are recommended.

Regular Cleaning

• After each ride, wipe down the shock with a clean rag to remove dirt and grime.
• Use a mild detergent and water to clean the shock if it becomes excessively dirty.
• Be sure to avoid solvents that may damage the shock’s seals or finish.

Checking for Leaks

Periodically inspect the shock for any signs of oil leakage or damaged seals. If oil is leaking from the shock, it may indicate that the seals are worn and need to be replaced.

Air Sleeve Maintenance

Over time, the air sleeve of the Monarch R shock can accumulate dirt, which can affect the shock’s performance. Periodically clean the air sleeve and lubricate it using the recommended shock oil.

Spring and Seal Care

RockShox recommends servicing the Monarch R rear shock every 50 hours of riding or once a year, whichever comes first. This service includes replacing seals and ensuring the shock functions optimally.

Troubleshooting Common Set-up Issues

Even with a high-performance shock like the Monarch R, issues can arise during setup or use. Below are common problems and their solutions.

1. Shock Feeling Too Stiff

• Possible Cause: Incorrect air pressure setting.
• Solution: Check the air pressure and adjust it based on your body weight and riding style. A soft setting may be necessary for more comfort.

2. Excessive Rebound

• Possible Cause: Rebound damping set too light.
• Solution: Adjust the rebound knob to slow down the return stroke by turning it clockwise.

3. Shock Not Returning Properly

• Possible Cause: Insufficient air pressure or rebound damping set too slow.
• Solution: Check and adjust the air pressure, and increase the rebound damping if necessary.

4. Noise from the Shock

• Possible Cause: Lack of lubrication or dirt in the air sleeve.
• Solution: Clean the shock, apply recommended lubrication, and inspect the seals for wear.

Customization and Optimization for Better Performance

The Monarch R rear shock offers several ways to customize and optimize your ride for various conditions and rider preferences.

• Tune Air Pressure Based on Terrain: For aggressive trail riding, increase the air pressure to prevent bottoming out. For more technical rides with lots of drops and jumps, a lower air pressure can provide better control and comfort.
• Adjust Rebound Damping for Riding Style: Riders who prefer smoother trails can reduce the rebound damping for a more active feel, while those on rough terrain may benefit from a slower rebound setting for better control.
• Upgrade to a More Advanced Spring Option: Although the Monarch R uses an air spring, riders seeking a more plush ride may opt for a coil shock instead for ultimate comfort and performance.

Comparison with Similar Models

While the Monarch R rear shock offers a good balance of performance and cost, other models in the RockShox lineup or from competing brands may provide different features.

• RockShox Deluxe: The Deluxe series offers more advanced adjustability, including high-speed compression damping. It’s ideal for riders who need more control on aggressive trails.
• Fox Float DPS: Known for its responsive damping system, the Fox Float DPS is a competitor in the same category as the Monarch R, with similar features but a slightly different feel.

For most recreational riders or cross-country enthusiasts, the Monarch R provides excellent performance at a more affordable price point compared to its competitors.

Compatibility with Other Drivetrain Components

The Monarch R rear shock is compatible with a wide range of mountain bike frames, but it’s important to check the specific dimensions and mounting hardware before purchase. Make sure the shock’s eye-to-eye length and stroke length match the frame’s specifications.

Additionally, ensure the shock’s performance characteristics align with your drivetrain components, particularly in terms of suspension performance during pedaling. A shock that provides too much travel or too little rebound control can negatively affect your pedaling efficiency and overall ride feel.
