Installation of the Revel RoughCut RCP35
Step 1: Preparing the Fork
Before installing the Revel RoughCut RCP35 [paid link] fork, ensure that your bike is compatible with a 35mm stanchion fork and that your frame is designed to accommodate the fork’s axle and steerer tube length. Clean your bike’s head tube thoroughly, as dirt and debris can lead to misalignment during installation.
Step 2: Attaching the Fork to the Headset
To install the fork, first, slide the fork’s steerer tube into the headset of your bike. Use a 5mm Allen wrench to tighten the headset compression bolt. Ensure that the fork is aligned correctly with the head tube and that the steer tube is not overtightened. Use a torque wrench [paid link] to tighten the headset bolt to the manufacturer’s specified torque setting.
Step 3: Installing the Front Wheel
Once the fork is securely mounted, install the front wheel by aligning the hub with the fork’s dropouts. Tighten the quick release lever or through-axle, depending on your bike’s specifications. Be sure that the axle is properly installed and that the wheel is centered in the fork.
Step 4: Setting Up the Suspension
The Revel RoughCut RCP35 suspension fork requires proper air pressure and compression settings to perform optimally. Use a suspension pump to set the air pressure based on your weight and riding style. Generally, a starting point would be around 20% of your rider weight in PSI, but you may need to fine-tune this based on personal preference. Adjust the rebound and compression settings to match the terrain you’ll be riding on.
Adjustment and Fine-Tuning
Adjusting the Air Pressure
The RoughCut RCP35 fork uses an air spring system, which provides customizable feel and performance. Adjusting the air pressure allows you to fine-tune the fork’s responsiveness. A higher PSI provides a firmer ride, ideal for aggressive riding, while lower pressure offers better comfort and sensitivity for smoother trails.
Compression Damping
The RoughCut RCP35 features an external compression damping adjustment that allows you to control how quickly the fork compresses under load. For smoother trails, you may want to set the compression to a softer setting, allowing the fork to absorb small bumps. For more technical or aggressive riding, a firmer setting will help resist bottoming out.
Rebound Adjustment
The rebound setting controls the speed at which the fork returns to its original position after compressing. A faster rebound speed can make the fork feel more lively, while a slower rebound offers better control and stability. Adjusting the rebound based on the terrain type is crucial to maximizing performance.
Travel Adjustments
The RCP35 allows riders to adjust the travel for different types of rides. Reducing the travel can improve pedaling efficiency, while increasing it enhances the fork’s ability to absorb larger impacts. Adjusting the travel also influences the geometry of the bike, which is an important factor to consider based on your riding preferences.
Maintenance of the Revel RoughCut RCP35
Regular Cleaning and Inspection
Regular maintenance is key to ensuring the longevity and performance of the Revel RoughCut RCP35. After every ride, clean the fork’s stanchions with a clean cloth to remove dirt and debris. This prevents any contamination from entering the seals and damaging the fork. Inspect the stanchions for any scratches or wear that could affect performance.
Oil Changes
The RoughCut RCP35 requires periodic oil changes to maintain smooth suspension action. Over time, the oil in the fork can break down, leading to poor performance. X-Fusion recommends changing the oil every 50 to 100 hours of riding, depending on riding conditions. Be sure to use the specific suspension oil recommended by the manufacturer.
Seals and Bushing Care
Check the seals on the fork for any signs of wear or damage. Seals prevent dirt, moisture, and debris from entering the internals of the fork. If you notice any damage to the seals, replace them immediately to avoid compromising the performance of the fork. Also, lubricate the bushings regularly to ensure smooth movement and reduce friction.
Spring Maintenance
While air springs don’t require as much maintenance as coil springs, it’s still important to check for any air leaks. Regularly check the air valve and the condition of the seals to ensure there are no leaks affecting the suspension pressure.
Troubleshooting Common Set-Up Issues
Fork Stiffness or Lack of Travel
If the fork feels too stiff or does not compress fully, check the air pressure settings. Too high of a PSI can lead to a stiff fork that does not offer enough travel. Lowering the PSI will help the fork perform as intended. Additionally, check the compression damping settings and adjust if necessary.
Excessive Rebound or Sluggish Response
If the fork feels too quick to rebound or too slow, adjust the rebound settings. For quicker responses, turn the rebound dial clockwise to slow down the return. For a slower rebound, turn the dial counterclockwise.
Noisy Forks
If you hear any strange noises coming from the fork during use, inspect the fork for dirt or damage. Clean the stanchions and check the seals. In some cases, improper lubrication of the bushings or insufficient air pressure can cause noises. Apply fresh oil and ensure the air pressure is within the recommended range.
Customization and Optimization for Better Performance
Upgrading to a Better Air Spring
If you want to improve the performance of the RoughCut RCP35, consider upgrading to a higher-quality air spring or a different compression damper cartridge. This can offer improved performance, especially for aggressive riders or those tackling difficult terrain.
Fine-Tuning Damping Settings
The Revel RoughCut RCP35 allows for precise adjustments in both compression and rebound. By dialing in these settings based on the terrain and riding style, you can significantly improve comfort, control, and handling. Don’t hesitate to experiment with various settings to find the optimal balance between performance and comfort.
Adjusting the Travel for Different Rides
Changing the fork’s travel can drastically affect your bike’s handling. Shortening the travel can make the bike more efficient for climbing and cross-country riding, while increasing the travel will help on downhill and technical rides. Experimenting with travel adjustments based on terrain will allow you to optimize the fork’s performance for different conditions.
Comparison with Similar Models
When comparing the Revel RoughCut RCP35 to other high-performance forks, it stands out for its balance of weight, stiffness, and smoothness. Models like the RockShox Pike and Fox 34 offer similar performance but may differ in terms of feel and adjustment options. The RoughCut RCP35’s external compression adjustment and customizable air spring make it a versatile [paid link] option for riders who want precise control over their fork’s performance.
Understanding Compatibility with Other Drivetrain Components
The Revel RoughCut RCP35 suspension fork is designed to work seamlessly with most modern road and mountain bike drivetrains. It is compatible with various axle standards, including 15mm and 20mm through-axles, and can be used with both Shimano and SRAM drivetrains. However, riders should ensure their bike’s frame has the necessary clearance for the fork, especially when upgrading to a model with different axle configurations or travel settings.
The RoughCut RCP35 works well with both 1x and 2x drivetrains, providing excellent handling and stability on technical descents or rough terrain. Riders should ensure their bike has the necessary brake mounts (IS or Post Mount) to ensure compatibility with the fork’s brake system.
