In this guide, we will dive deep into the engineering that makes the Revelation RC stand out. This includes its installation, maintenance, troubleshooting, customization options, and its compatibility with other components. Whether you’re a beginner or an experienced rider, this comprehensive guide will equip you with the knowledge needed to get the most out of your Revelation RC fork.

Installation of the Revelation RC Fork

Proper installation of the Revelation RC is crucial for both safety and performance. The fork is designed to be installed easily, but it requires precision to ensure everything works optimally.

Step-by-Step Installation

1. Remove your old fork: Before installing the new Revelation RC, ensure you remove the old fork and headset. Use a headset press tool to safely remove the headset from the frame.
2. Install the fork steerer tube: Place the Revelation RC fork into the head tube of your frame. The steerer tube should be slightly longer than needed. After inserting it, mark the length and use a pipe cutter or hacksaw to cut the steerer tube to the required size.
3. Install the star nut: Insert the star nut into the top of the steerer tube using a star nut tool. Ensure it is properly seated to prevent any movement while tightening the stem.
4. Install the headset components: Place the top headset bearing and the bottom headset bearing into the head tube. Carefully place the fork into the bearings, ensuring smooth movement.
5. Attach the stem: Align the stem to the fork steerer tube and tighten the bolts evenly. Ensure that the stem is positioned correctly and that all bolts are torqued to the recommended specifications.
6. Install the front wheel: Place the wheel into the fork dropouts and tighten the quick-release skewer or axle. Make sure the wheel is straight and aligned with the fork.

Once installed, double-check the alignment of the fork with the wheel and ensure that all bolts are torqued correctly.

Adjustment of the Revelation RC Fork

The Revelation RC fork features several adjustments that allow you to fine-tune your suspension to suit your riding style and terrain. These include rebound, compression, and air pressure adjustments.

Rebound Adjustment

• Purpose: Rebound controls the speed at which the fork returns after compression. A properly set rebound ensures that the fork absorbs bumps smoothly and does not bounce back too quickly.
• How to Adjust: Turn the rebound dial located on the bottom of the fork leg. Turning it clockwise will slow the rebound, while counterclockwise will speed it up. Start with the rebound setting in the middle and adjust based on your ride experience.

Compression Adjustment

• Purpose: Compression adjustment controls how the fork reacts to impacts and heavy loads. The Revelation RC fork features an external compression adjustment that affects low-speed compression.
• How to Adjust: The compression dial is located on the top of the fork. Turning it clockwise will stiffen the compression, making the fork less sensitive to small bumps. Turning it counterclockwise will make the fork more responsive to small impacts.

Air Pressure Adjustment

• Purpose: The Revelation RC fork uses an air spring system that can be adjusted to provide the desired amount of support for your weight and riding conditions.
• How to Adjust: Use a shock pump to adjust the air pressure in the air spring. The recommended air pressure varies based on rider weight, so consult the manufacturer’s chart for guidance. Adjust the air pressure to your comfort level, keeping in mind that a higher pressure will result in a firmer ride, while lower pressure will provide more plushness.

Maintenance of the Revelation RC Fork

Maintaining your Revelation RC suspension fork is essential for ensuring long-term performance and durability. Regular maintenance will also improve ride quality and prevent issues from arising.

Regular Cleaning

• How to Clean: After each ride, use a damp cloth to wipe down the fork stanchions to remove dirt and debris. This will prevent contaminants from entering the seals and damaging the fork internals.
• Lubrication: Apply a small amount of suspension fluid or fork oil to the stanchions after cleaning to maintain smooth fork operation.

Oil Change

• Frequency: Regular oil changes are necessary to maintain the fork’s performance. The Revelation RC fork should be serviced every 50-100 hours of riding, depending on the conditions.
• How to Change the Oil: To change the oil, remove the fork legs and drain the old fluid. Refill with the recommended type and amount of suspension oil as per the manufacturer’s guidelines. This will ensure proper lubrication of the fork’s internals.

Seals and Bushings

• Inspection: Inspect the seals and bushings periodically for any signs of wear or leakage. If the seals are damaged or leaking fluid, they will need to be replaced.
• Maintenance: Apply a light coating of suspension grease to the seals and bushings to prevent wear and ensure smooth action.

Troubleshooting Common Issues

While the Revelation RC fork is a durable and high-performing component, issues can sometimes arise. Below are common problems and troubleshooting tips.

Fork Not Compressing Properly

• Possible Cause: The air pressure may be too low, or the compression damping may need adjustment.
• Solution: Check and adjust the air pressure in the fork using a shock pump. If the air pressure is correct, fine-tune the compression settings to ensure proper responsiveness.

No Rebound Control

• Possible Cause: The rebound damping may be set incorrectly, or the fork may need maintenance.
• Solution: Check the rebound setting and adjust it according to your preference. If no adjustment is noticed, it may indicate an issue with the fork’s internal oil or seals, requiring service.

Leaking Oil

• Possible Cause: Worn seals or damaged fork legs may be the cause of oil leakage.
• Solution: Inspect the seals for damage and replace them if necessary. If the leakage persists, take the fork to a professional for further inspection.

Customization and Optimization

Customizing your Revelation RC fork can optimize your riding experience, ensuring that it performs at its best for your specific needs. Customization can include adjusting settings for different terrains, using specific oil weights, or upgrading components.

Tuning for Different Terrains

• Cross-Country (XC): For XC riding, set the fork to a firmer compression setting and a higher air pressure to minimize bobbing and improve pedaling efficiency.
• Enduro/All-Mountain: For enduro or all-mountain riding, set the fork to be more plush, with a softer compression and lower air pressure, to handle rougher trails and larger impacts.

Upgrading Internal Components

You can upgrade the Revelation RC with components like high-end oil, upgraded seals, or custom dampers for improved performance. These upgrades may provide smoother action, better damping, and longer service life.

Comparison with Similar Models

When considering suspension forks, the Revelation RC competes with other models like the RockShox Pike and Fox 34. Here’s a quick comparison:

• Revelation RC: Lightweight, affordable, and well-suited for a wide range of riders and terrains.
• Pike: More robust than the Revelation, the Pike is aimed at aggressive riders who need more travel and a stiffer fork.
• Fox 34: Similar in performance but often favored for its high-end damper and plush feel on rough terrain.

The Revelation RC offers excellent value for riders looking for a reliable and versatile fork without the higher price tag of the Pike or Fox 34.

Compatibility with Other Drivetrain Components

The Revelation RC fork is compatible with a wide range of drivetrain systems, including Shimano, SRAM, and others. It is important to ensure that the fork’s axle standards and travel align with your bike’s frame and other components. Additionally, the fork works well with both 29” and 27.5” wheels, making it a versatile choice for many setups.

Key Compatibility Considerations

• Axle Standards: The fork uses a 15mm thru-axle, which is compatible with most modern mountain bike frames.
• Brake Mounting: The Revelation RC fork typically uses post-mount brake standards. Ensure that your brake calipers are compatible with the fork’s mounting system.

By understanding these factors, you can ensure that your Revelation RC fork integrates seamlessly with your existing bike components.
