Installation of the Revel RoughCut RCP35 Suspension Fork
The installation of the Revel RoughCut RCP35 suspension fork is straightforward, but it requires careful attention to detail to ensure optimal performance and safety. Follow these steps for proper installation:
1. Prepare the Bike
Place your bike on a bike stand [paid link] to keep it stable during the installation process. Ensure the front wheel is removed, as you will need to replace the fork.
2. Remove the Old Fork
Using a 5mm Allen wrench [paid link], remove the brake caliper from the old fork, if necessary. Then, detach the fork by loosening the headset top cap with a 6mm Allen wrench [paid link]. You may need to use a mallet to gently tap the old fork out of the headset.
3. Install the New Fork
Slide the Revel RoughCut RCP35 into the headset tube, ensuring that it aligns properly with the frame. Secure the fork by tightening the headset top cap with a torque wrench [paid link]. Follow the manufacturer’s torque specifications to avoid over-tightening.
4. Attach the Brake System
Reinstall the brake caliper, ensuring proper alignment with the rotor. Tighten the bolts to the recommended torque specification.
5. Set the Stem and Handlebar
Reinstall the stem and handlebars, ensuring they are properly aligned. Tighten the stem bolts to the specified torque setting. Perform a final check to ensure all components are securely fastened.
Adjustment and Tuning for Optimal Performance
The Revel RoughCut RCP35 suspension fork is highly customizable, allowing you to fine-tune its performance based on your riding style and preferences. Here are some key adjustments to make:
Air Pressure
Adjusting the air pressure in the fork is crucial to achieve the ideal suspension feel. To adjust the air pressure:
- Use a shock pump to adjust the air pressure in the positive air chamber.
- Set the recommended pressure based on your weight, as specified in the user manual.
- Check the sag (the amount the suspension compresses under rider weight) and make adjustments until it falls within the recommended range.
Compression Damping
The Revel RoughCut RCP35 features a compression damping adjuster that lets you fine-tune how the fork behaves during hits and impacts. To adjust compression damping:
- Turn the compression dial clockwise to increase damping (firmer suspension) or counterclockwise to decrease damping (softer suspension).
- Start with the manufacturer’s recommended setting and make small adjustments until you achieve your preferred feel.
Rebound Damping
Rebound damping controls how quickly the fork returns to its original position after compression. Adjust this using the rebound knob located at the bottom of the right leg of the fork:
- Turn the rebound dial clockwise for a slower rebound (useful for high-speed, aggressive riding).
- Turn the dial counterclockwise for a faster rebound (helpful for smoother terrain).
Fine-tuning the rebound ensures that your fork returns efficiently without bouncing or feeling too stiff.
Maintenance and Care
Proper maintenance is key to prolonging the lifespan of your Revel RoughCut RCP35 suspension fork and maintaining its optimal performance. Regular care includes:
Cleaning
After every ride, clean the fork to remove dirt, mud, and debris that may accumulate on the stanchions and seals. Use a soft brush and a degreaser to clean the fork. Pay special attention to the seals, as dirt buildup can cause leaks and reduce performance.
Lubrication
Regularly lubricate the stanchions with a fork-specific lubricant. Apply the lubricant sparingly to avoid excess buildup. Wipe off any excess to prevent dirt from sticking.
Oil Change
Perform a full oil change every 50-100 hours of riding or once a season, whichever comes first. This will ensure that the internal damping system works smoothly and the fork performs at its best. Follow the manufacturer’s recommendations for the correct oil type and quantity.
Seal Replacement
The fork’s seals are essential for keeping dirt and moisture out of the internals. Over time, seals may wear out, leading to reduced performance or oil leaks. Inspect the seals regularly and replace them as necessary to prevent further damage to the fork.
Troubleshooting Common Issues
While the Revel RoughCut RCP35 is built for reliability, you may encounter a few common issues that can affect its performance. Here are some solutions:
1. Fork Feels Too Soft
- Cause: Insufficient air pressure or too much compression damping.
- Solution: Check the air pressure and ensure it’s set correctly for your weight. Adjust the compression damping to a firmer setting if necessary.
2. Fork Is Noisy
- Cause: Dirt or debris in the seals or stanchions.
- Solution: Clean the fork thoroughly and lubricate the stanchions to eliminate any noise caused by friction.
3. Loss of Travel or Sag
- Cause: Internal oil leak or seal damage.
- Solution: Perform a visual inspection of the seals and oil levels. If you notice any leakage, it may be necessary to replace the seals or perform an oil change.
4. Rebound or Compression Adjustments Not Working
- Cause: Air pressure too high or internal damage.
- Solution: Check the air pressure and adjust accordingly. If the issue persists, it may require a professional service to inspect the internal components.
Customization and Optimization for Better Performance
Customizing your Revel RoughCut RCP35 suspension fork can significantly improve your riding experience. Here are some tips for optimization:
- Spring Rate Adjustment: If the fork feels too stiff or too soft, consider adjusting the spring rate by adding or removing air volume spacers. This allows for a more customized feel, especially for different riding styles.
- Upgrade Seals: If you ride in extremely muddy or wet conditions, consider upgrading the fork’s seals to a higher-quality option that offers better protection against the elements.
- Tune the Damping: Fine-tune the compression and rebound settings based on the terrain you ride most often. For example, reduce compression damping for more trail-sensitive responsiveness or increase it for better control on downhill runs.
Compatibility with Other Drivetrain Components
The Revel RoughCut RCP35 suspension fork is designed to work seamlessly with a variety of drivetrain systems, but it’s essential to ensure compatibility with your specific bike setup. When considering compatibility, check the following:
- Axle Type: The fork is compatible with both quick release and thru-axle systems. Ensure your bike’s axle type matches the fork’s specifications.
- Headset Type: The Revel RoughCut RCP35 requires a standard tapered headset. Make sure your frame is equipped with a compatible headset to fit the fork.
- Brake Mounts: The fork is designed with post-mount brake calipers, so ensure your brake system is compatible with this type of mounting. Some frames may require adapters for correct installation.
By understanding these compatibility factors, you can ensure that your suspension fork integrates seamlessly with your bike’s drivetrain components, maximizing performance and comfort.
