The Revel RoughCut RCP35 [paid link] suspension fork from X-Fusion is designed to offer top-tier performance for serious mountain bikers. Like all high-performance bike components, maintaining your suspension fork properly is essential for maximizing performance and ensuring longevity. In this article, we will walk you through the installation, adjustment, and maintenance of the Revel RoughCut RCP35 [paid link], as well as common troubleshooting issues, customization tips, and compatibility considerations with other drivetrain components.

Installation of the Revel RoughCut RCP35

Before installing the Revel RoughCut RCP35 suspension fork, it’s essential to ensure that your bike’s frame and headset are compatible. This fork is suitable for modern mountain bikes with a tapered steerer tube. Follow these steps to correctly install the fork.

1. Prepare the Bike: Remove the front wheel, brake calipers, and existing fork from your bike.
2. Install the Headset and Bearings: If you are replacing an old fork, make sure to remove the headset and clean the bearing surfaces before installing new bearings. The Revel RoughCut RCP35 uses a tapered headset, so ensure that your bike frame has the corresponding headset for a proper fit.
3. Install the Fork: Slide the steerer tube of the Revel RoughCut RCP35 into the headset, making sure it is seated properly. Install the compression ring, top cap, and stem in the correct order, and tighten them according to the manufacturer’s specifications.
4. Install the Front Wheel: Attach the front wheel to the fork by securing the axle and making sure it is aligned correctly.
5. Connect the Brake Calipers: Mount the brake calipers and ensure that they are centered on the rotor. Adjust the brake pads so that there is no rubbing.

Ensure that all bolts are torqued to the recommended settings to avoid any issues while riding.

Adjusting the Revel RoughCut RCP35

Proper adjustment of your suspension fork is key to achieving a smooth and controlled ride. The Revel RoughCut RCP35 features adjustable air spring and damping systems that allow you to fine-tune the fork’s performance for different riding styles and trail conditions.

Air Spring Setup

1. Setting the Sag: The air spring is designed to offer a custom feel depending on your weight and riding style. To set the correct sag, inflate the air spring to the recommended pressure for your weight, then press down on the handlebars while sitting on the bike. Check the sag by observing how much the fork compresses. A good starting point is to aim for around 25-30% of travel.
2. Adjusting the Air Pressure: If the fork feels too soft or too stiff, adjust the air pressure in the air spring. Increase the pressure for a firmer feel or reduce it for a softer ride. Make small adjustments and test ride to find the optimal pressure.

Damping Adjustment

1. Rebound Damping: The rebound damping controls the speed at which the fork returns after compression. To adjust, turn the rebound dial (usually located at the bottom of the fork legs) clockwise to slow down the rebound or counterclockwise to increase the rebound speed. Adjust the setting based on trail conditions—slower rebound for rough terrain and faster rebound for smoother trails.
2. Compression Damping: The compression damping adjusts how much resistance the fork has when compressed. Turning the dial clockwise increases compression damping for more support during aggressive riding, while turning it counterclockwise makes the fork more plush. Find the balance that suits your riding style.

Lockout Feature

The Revel RoughCut RCP35 includes a lockout feature that can be used when riding on smooth trails or during climbing. Engaging the lockout will prevent the fork from compressing, providing better pedaling efficiency. Make sure to disengage the lockout when hitting rougher terrain for full suspension travel.

Regular Maintenance of the Revel RoughCut RCP35

To ensure optimal performance, it’s important to perform regular maintenance on your Revel RoughCut RCP35 fork. This includes basic cleaning, lubrication, and servicing of the air spring and damper systems.

Cleaning the Fork

1. Wipe Down the Fork: After each ride, use a clean rag to wipe down the fork’s stanchions and lower legs. This prevents dirt and grime from entering the seals.
2. Check the Seals: Inspect the fork seals for any visible damage or wear. Clean them gently with a microfiber cloth to remove any debris.

Servicing the Air Spring

1. Top-Up Air Pressure: Over time, the air pressure in the spring can decrease. Regularly check and top-up the air pressure to maintain the proper sag.
2. Service the Air Spring: Every 50-100 hours of riding, it is recommended to service the air spring. This includes disassembling the fork, cleaning the air spring, and lubricating the necessary components.

Servicing the Damper

1. Check Oil Levels: Every 100-150 hours of riding, check the oil level in the damper. Low oil levels can affect performance, so be sure to top up as necessary.
2. Change Oil: Over time, the oil inside the damper can break down. It’s essential to change the oil periodically, depending on the riding conditions and frequency of use.

Seals and Bushings Maintenance

The bushings inside the fork can wear out with time, leading to a loss of performance. Perform regular checks on the bushings and seals and replace them if you notice any play or excessive friction.

Troubleshooting Common Issues with the Revel RoughCut RCP35

Although the Revel RoughCut RCP35 is a high-quality suspension fork, issues can arise with extended use. Below are some common problems and their solutions.

Fork Not Returning Properly (Slow Rebound)

• Cause: The rebound damping might be set too slow, or the oil inside the damper could be contaminated or low.
• Solution: Adjust the rebound dial to increase the rebound speed. If this doesn’t solve the issue, check the oil level and replace it if necessary.

Fork Bottoming Out Too Easily

• Cause: Low air pressure in the air spring or improper compression settings.
• Solution: Increase the air pressure to the recommended levels and adjust the compression damping to provide more support during compression.

Excessive Stiction or Rough Movement

• Cause: Dirty stanchions or damaged seals.
• Solution: Clean the stanchions thoroughly and inspect the seals for damage. Replace seals if necessary.

Customization and Optimization for Better Performance

The Revel RoughCut RCP35 is built for a wide range of riders, and customizing it for your riding style is essential for optimal performance. Consider the following:

1. Spring Rate: Experiment with different air pressures to adjust the spring rate. Lighter riders may prefer a softer setup, while heavier riders may need a stiffer setup for better performance.
2. Damping Settings: Adjust the compression and rebound damping based on the terrain you typically ride. For aggressive downhill trails, you may need higher compression damping and slower rebound.
3. Lockout Usage: Engage the lockout feature during smooth climbs to prevent unnecessary fork movement and improve pedaling efficiency.

Compatibility with Other Drivetrain Components

The Revel RoughCut RCP35 is designed to work seamlessly with most modern mountain bike drivetrains. However, it’s important to ensure that your fork’s axle and brake mounts are compatible with your wheelset and brake system. The fork comes with a 15mm or 20mm thru-axle option, so make sure your wheelset supports the correct axle type.

Additionally, when using the fork with a suspension rear shock, ensure that the suspension travel and geometry of your bike frame are compatible with the travel of the RoughCut RCP35.

Conclusion

Maintaining and optimizing your Revel RoughCut RCP35 suspension fork is key to enhancing your riding experience and extending the life of the fork. By following proper installation, adjustment, and maintenance procedures, you can ensure that your fork performs at its best for years to come. Always pay attention to signs of wear or issues and address them promptly to avoid more significant problems down the line.
