Replacing the derailleur cables is an essential maintenance task to keep your shifting smooth and reliable. This guide walks you through the step-by-step process of replacing the derailleur cables for the Super Record WRL rear derailleur. Whether you’re a beginner or an experienced cyclist, you will find this detailed instruction easy to follow.
Tools Required
- 5mm Allen wrench
- 2mm Allen wrench
- Cable cutters
- Needle nose pliers
- Screwdriver (flat-head)
- Lubricant
- New derailleur cables (Campagnolo compatible)
- 10mm open-end wrench (optional)
- Rags or cleaning cloth
Preparing Your Bike
Before starting the cable replacement process, make sure your bike is secure. Place it on a bike stand to keep it stable during the procedure. Ensure that the drivetrain area is clean and free of debris to avoid any interference while working with the components.
Removing the Old Derailleur Cables
Step 1: Shift to the Smallest Gear
Shift the rear derailleur to the smallest cog on the cassette. This ensures that the derailleur has the least tension, making it easier to remove the cables.
Step 2: Disconnect the Derailleur from the Frame
Use a 5mm Allen wrench to remove the rear derailleur from its hanger. This allows you to access the derailleur more easily while working on the cables.
Step 3: Remove the Cable from the Derailleur
Locate the barrel adjuster on the rear derailleur. Use the 2mm Allen wrench to loosen the bolt holding the cable in place. Carefully pull the cable out of the derailleur. If there’s any resistance, use needle nose pliers to gently pull the cable through.
Step 4: Remove the Cable from the Housing
Once the cable is free from the derailleur, remove it from the outer cable housing. Inspect the housing for any damage or wear and replace it if necessary. Clean the housing thoroughly to ensure smooth operation of the new cable.
Installing the New Derailleur Cables
Step 1: Prepare the New Cables
Before installing the new derailleur cables, ensure they are the correct length. Campagnolo’s Super Record WRL system requires precise cable lengths to perform optimally. Measure and trim the new cables using cable cutters, ensuring they’re slightly longer than needed for smooth routing.
Step 2: Lubricate the New Cables
Lubricate the new cables lightly with a bicycle-specific lubricant. This reduces friction and ensures smooth shifting performance. Avoid over-lubricating, as excess lubricant can attract dirt.
Step 3: Thread the Cable Through the Housing
Begin by threading the new cable into the outer housing. Start from the rear derailleur side, and gently push the cable through the housing towards the shifter. Take care not to kink the cable during this process.
Step 4: Insert the Cable into the Derailleur
Once the cable is fully routed through the housing, insert the end into the rear derailleur. Use the 2mm Allen wrench to tighten the cable tension bolt. Be sure the cable is fully seated and there is no slack.
Step 5: Reattach the Derailleur to the Frame
Now that the cable is secure in the derailleur, reattach the rear derailleur to the frame using the 5mm Allen wrench. Tighten the bolt to the recommended torque specifications to prevent the derailleur from becoming loose.
Adjusting the Cable Tension
Step 1: Fine-tune the Barrel Adjuster
To ensure optimal shifting performance, adjust the barrel adjuster. Start by turning the barrel adjuster counterclockwise to increase tension. Shift through all the gears to test how the derailleur responds. If you notice skipping or mis-shifting, fine-tune the tension by adjusting the barrel adjuster.
Step 2: Test Shifting Performance
Shift through the gears multiple times to ensure the derailleur shifts smoothly and accurately. If the shifting feels sluggish or delayed, adjust the tension again using the barrel adjuster until you achieve the desired response.
Securing the Cable and Final Adjustments
Step 1: Trim Excess Cable
Once you are satisfied with the shifting performance, trim the excess cable using cable cutters. Leave a small length of cable beyond the derailleur, as this allows for future adjustments if needed.
Step 2: Crimp the Cable End
Place a crimping ferrule onto the end of the cable to prevent fraying. Use needle nose pliers to crimp the ferrule securely.
Step 3: Clean the Area
Wipe down the derailleur and the surrounding area with a clean rag to remove any grease or lubricant residues. This will keep your bike looking tidy and prevent dirt from building up.
Troubleshooting Common Set-Up Issues
1. Skipping Gears or Slow Shifting
If you notice that your bike is skipping gears or shifting slowly after replacing the cables, it’s likely due to improper cable tension. Revisit the barrel adjuster to make minor adjustments and ensure the cable is taut enough to engage properly with the derailleur.
2. Poor Shifting in the Highest and Lowest Gears
If the derailleur struggles to shift smoothly into the highest or lowest gear, the cable tension may be too tight or too loose. Adjust the barrel adjuster slowly and re-test shifting to fine-tune performance.
3. Friction or Noise in the Cable Housing
If you hear friction or noise coming from the cable housing, check for bends or kinks in the housing. Ensure that it is properly routed and free of debris. Replacing old, worn-out housing may be necessary for smoother performance.
Conclusion
Replacing the derailleur cables on your Campagnolo Super Record WRL rear derailleur is a simple yet crucial task for maintaining optimal shifting performance. With the proper tools and steps outlined in this guide, you can easily replace the cables yourself, ensuring that your bike is always ready for your next ride. Regular maintenance like this not only improves your bike’s performance but also prolongs the life of your components.
