Installation of the Revel RoughCut RCP35 Suspension Fork
Before installing the RCP35, ensure that your bike frame is compatible with the fork’s dimensions, particularly the steerer tube length, axle type, and brake mount configuration. Follow these steps for proper installation:
- Remove the Old Fork: Begin by removing your previous fork. Use an 8mm Allen wrench to remove the headset top cap and the stem bolts. Detach the fork from the frame, ensuring that any cables or hoses are disconnected safely.
- Install the RCP35 Steerer Tube: Slide the steerer tube of the RCP35 into the headset of the bike frame. Ensure the fork is centered and aligned correctly.
- Reattach the Headset: Use the 8mm Allen wrench to tighten the headset top cap, making sure the fork moves smoothly without any play. Reattach the stem and tighten the bolts using the correct torque specifications.
- Install the Axle: Secure the through-axle using a 15mm through-axle tool. Ensure it is tight enough to prevent any play but does not over-tighten, which could damage the fork or axle.
- Brake Mount: If your bike uses disc brakes, mount the brake caliper to the fork’s brake tabs using the provided bolts. Tighten them securely with a T25 Torx driver.
Adjusting the Revel RoughCut RCP35 Suspension Fork
Proper adjustment is critical to getting the most out of your Revel RoughCut RCP35 [paid link]. There are several key adjustments you should make for personalized comfort and performance:
Setting the Air Pressure
The first step in tuning your suspension fork is setting the correct air pressure. The RCP35 uses a coil-spring system with an air shock for damping. Adjusting the air pressure affects how the fork compresses and rebounds during use.
- Find the Recommended Pressure: Check the recommended air pressure based on your weight in the fork’s user manual or X-Fusion’s guidelines. Typically, you’ll want to start with a pressure that’s close to your body weight in pounds.
- Use a Shock Pump: Attach a shock pump to the air valve on the fork’s crown. Inflate or deflate the fork to the desired pressure.
- Test and Fine-Tune: Take the bike for a short ride to test the pressure. Adjust as necessary to ensure that the fork feels plush but does not bottom out during aggressive riding.
Compression and Rebound Adjustments
The compression and rebound damping adjustments allow you to control the fork’s performance in different riding conditions.
- Compression: The compression knob controls how fast the fork compresses under pressure. To adjust, turn the compression knob clockwise to increase compression (firmer) or counterclockwise to decrease it (softer). This adjustment is vital for technical climbs or rough terrain, where you want a firmer fork for better handling.
- Rebound: The rebound knob regulates the speed at which the fork returns to its original position after compression. To adjust, turn the rebound knob clockwise to slow down the rebound (firmer) or counterclockwise to speed it up (softer). A proper rebound setting ensures the fork doesn’t bounce uncontrollably after compressing.
Maintenance of the Revel RoughCut RCP35 Suspension Fork
Regular maintenance ensures that your suspension fork operates smoothly and lasts for a long time. Follow these steps to keep your RCP35 in top shape:
Cleaning the Fork
- Wipe the Stanchions: After every ride, clean the stanchions (the upper fork tubes) with a clean rag. Dirt and debris can cause damage to the seals over time if left unchecked.
- Inspect the Seals: Check the fork seals regularly for any signs of wear or damage. If the seals are compromised, oil can leak, which can cause the fork to lose its performance.
Fork Oil Change
Fork oil plays a crucial role in damping performance and maintaining smooth operation. Over time, the oil can degrade and reduce performance.
- Disassemble the Fork: Use an 8mm Allen wrench to remove the bolts securing the lower legs of the fork. Carefully separate the lower legs from the upper fork.
- Drain the Oil: Drain the old fork oil into a clean container. Take note of the amount of oil that comes out.
- Refill with Fresh Oil: Refill the fork with the recommended amount and type of fork oil as specified by X-Fusion. Be sure to add the correct weight of oil to each side of the fork.
- Reassemble the Fork: Once the oil is replaced, reassemble the fork by securing the lower legs back to the upper fork. Tighten all bolts to the specified torque settings.
Servicing the Damper
The damper controls compression and rebound damping. It is essential to check the damper regularly for proper function.
- Remove the Damper: Using the proper tools, carefully remove the damper from the fork. This may involve removing the air cap and separating the damper from the fork stanchions.
- Check for Leaks: Inspect the damper for any visible signs of damage or leaks. If the damper appears to be malfunctioning, consider sending it to a professional for repair or replacement.
Troubleshooting Common Set-Up Issues
Despite the Revel RoughCut RCP35’s high quality, some common setup issues may arise. Here’s how to troubleshoot them:
Fork Bottoming Out
If the fork bottoms out during a ride, it could be due to insufficient air pressure. Increase the air pressure slightly until the fork no longer bottoms out. If you’re already at the recommended pressure, check the rebound and compression settings to ensure they are properly tuned.
Fork Not Moving Smoothly
If the fork feels sticky or sluggish, the seals may be clogged with dirt, or the fork oil may be too old. Clean the stanchions and inspect the seals for damage. If necessary, change the fork oil.
Noisy Fork
A noisy fork could be a sign of dirt in the seals or insufficient lubrication. Clean the fork thoroughly and lubricate the seals. If the noise persists, it may be necessary to replace the seals.
Customization and Optimization for Better Performance
To optimize the Revel RoughCut RCP35 for your riding style, consider the following tips:
- Air Pressure Adjustment: Fine-tune the air pressure to your weight and riding style. Lighter riders may benefit from slightly lower air pressure, while heavier riders may need higher pressure for better support.
- Compression Settings: Adjust the compression settings to match the terrain you’re riding. For smooth trails, softer compression settings may be ideal, while rougher trails or downhill sections might require firmer settings.
- Rebound Settings: Ensure the rebound setting is balanced for your riding style. Too fast a rebound may cause the fork to bounce excessively, while too slow a rebound can cause the fork to feel unresponsive.
Comparison with Similar Models
When comparing the Revel RoughCut RCP35 to similar models in the market, such as the RockShox Pike or Fox 36, the RCP35 offers excellent value for money with a focus on adjustability and comfort. It is slightly more affordable than some of its competitors while still providing top-notch performance. The RockShox Pike offers more advanced damping technology, but the RCP35 offers similar features at a more accessible price point. The Fox 36 provides more aggressive handling and a slightly more refined ride, but again, the RCP35 is a strong contender in terms of price and performance balance.
Understanding Compatibility with Other Drivetrain Components
The Revel RoughCut RCP35 is designed to be compatible with a wide range of drivetrain components, including 1x and 2x setups. However, it’s important to ensure that your bike’s axle configuration, brake system, and headset type are compatible with the fork. The fork uses a 15mm through-axle, so make sure your frame supports this standard.
