Disassembling the Fork for Service
Before you begin servicing the Revel RoughCut RCP35, ensure that the bike is securely mounted in a workstand and the front wheel is removed. Disassembling the fork properly is critical for effective servicing.
- Remove the Fork from the Bike
- Loosen and remove the fork from the headset using the appropriate Allen wrench. Be sure to keep track of all the headset spacers, washers, and other parts as you remove the fork.
- Remove the Air Pressure
- Use an air pump to deflate the fork. Attach the pump to the air valve and press the valve to release the air pressure fully.
- Remove the Damper and Spring Assembly
- Use the 6mm Allen wrench to remove the bolt securing the damper assembly and the air spring. Once removed, take out the assembly carefully and set it aside.
- Disassemble the Lower Leg
- With the air spring and damper removed, you can now focus on the lower leg. Using a 5mm Allen wrench, remove the bolts holding the lower legs of the fork. After the bolts are removed, gently pull the lowers away from the upper stanchions, ensuring that no internal parts are damaged.
- Drain the Oil
- Tilt the fork over the basin or container and let the old suspension oil drain completely. This is crucial to remove old, degraded oil and prevent mixing with new oil.
Cleaning the Fork
Once the fork is disassembled, cleaning all the parts thoroughly is essential for a smooth reassembly.
- Clean the Stanchions
- Use a clean rag or paper towel to wipe down the stanchions. Apply a bit of suspension oil to the stanchions before reassembly to help lubricate the seals.
- Clean the Lowers and Damper Assembly
- Use a small brush and clean the inside of the lowers to remove any dirt, debris, or old oil. Ensure that all seals are free of contaminants. For the damper assembly, use a rag to clean off any old oil or grime.
- Check for Wear on Seals
- Inspect the seals for signs of wear or damage. If the seals appear worn, it is recommended to replace them with new ones. Always use manufacturer-recommended seals for proper fit and function.
Replacing Oil and Servicing Seals
Proper oil replacement and seal maintenance are crucial for the Revel RoughCut RCP35’s continued performance.
- Reinstall the Damper and Spring Assembly
- Before installing the damper and air spring assembly, apply fresh suspension oil (according to X-Fusion’s specifications) to the internal parts and stanchions.
- Install the Seals
- Apply a thin layer of stanchion seal grease to the new seals before installation. This ensures smooth movement and minimizes the risk of stiction. If necessary, use a seal driver to help install the seals correctly without damaging them.
- Fill with Fresh Suspension Oil
- Using a syringe, carefully fill the lowers with the specified amount of suspension oil. Refer to the X-Fusion manual for the exact amount and type of oil required for the Revel RoughCut RCP35.
- Reassemble the Fork
- Reattach the lower legs to the upper stanchions, ensuring that the internal parts align correctly. Tighten the bolts with a torque wrench [paid link] to the manufacturer’s specified torque values. This ensures that the fork is properly secured without causing damage to the threading.
- Reinstall the Air Spring Assembly
- Once the lowers are secured, reassemble the air spring assembly by aligning it with the fork’s internals and securing it with the appropriate bolts. Ensure that the air spring is properly installed, and check for any leaks once the air is reintroduced.
Adjusting the Fork
After completing the reassembly, you’ll need to set the fork’s air pressure and damping settings to your preferences.
- Set the Air Pressure
- Using an adjustable air pump, set the recommended air pressure for your rider weight. This is crucial for achieving the desired ride feel. The correct air pressure ensures the fork offers optimal travel without bottoming out or feeling overly stiff.
- Adjust the Damping
- The Revel RoughCut RCP35 features compression and rebound damping adjustments. Set the rebound damping to match your riding style, with slower rebound settings for more control and faster settings for a more responsive feel. Adjust the compression damping for either a plush ride or a firmer feel depending on the terrain.
- Check for Leaks
- After adjusting the air pressure, check for any air leaks at the valve. Use Teflon tape on the valve threads if you notice any leaks.
Troubleshooting Common Issues
While the Revel RoughCut RCP35 is a reliable suspension fork, occasional issues can arise. Here are some common problems and solutions.
- Fork Not Holding Air Pressure
- If the fork loses air pressure, inspect the air spring assembly for damage. You may need to replace the air seals or the entire assembly if it’s worn out.
- Poor Rebound Performance
- If the rebound feels too fast or too slow, it may be due to incorrect damping settings. Adjust the rebound dial until you achieve a consistent return rate throughout the fork’s travel.
- Noisy Fork
- If you hear unusual noises from the fork, check the stanchion seals for wear or contamination. Re-grease the seals and ensure that all components are properly lubricated.
Customizing and Optimizing Your Revel RoughCut RCP35
For riders looking to optimize the performance of the Revel RoughCut RCP35, several customization options are available.
- Fine-Tuning Damping Settings
- To achieve the best performance for your specific riding style, fine-tune the compression and rebound damping. This can make the fork feel more responsive or provide additional plushness for rough terrain.
- Upgrading the Air Spring
- Consider upgrading to a different air spring for better support on your riding style or terrain. A heavier rider may prefer a firmer spring, while lighter riders may benefit from a softer setup for improved comfort.
- Changing the Oil Viscosity
- Adjusting the oil viscosity can influence the fork’s responsiveness. A thicker oil provides more damping resistance, while a thinner oil offers a smoother, faster response. Test different viscosities to find the best performance for your riding conditions.
Compatibility with Other Drivetrain Components
The Revel RoughCut RCP35 is designed to integrate seamlessly with other high-performance drivetrain components. When choosing a drivetrain setup, ensure that your fork’s travel, air pressure, and damper settings align with the overall system. Compatibility with wheels, tires, and headset systems is also essential for optimal handling and ride quality.
By regularly servicing your Revel RoughCut RCP35 suspension fork, you can maintain top-notch performance, extend its lifespan, and avoid unexpected failures. With proper care, this fork will continue to deliver exceptional performance on all your rides.
