Replacing the cable on your Campagnolo Chorus 11s [paid link] front derailleur is essential for ensuring smooth, precise shifting. Over time, cables stretch, become frayed, or wear out, leading to poor shifting performance. This step-by-step guide will walk you through the process of replacing the cable on your Chorus 11s [paid link] front derailleur to keep your drivetrain running at its best.
Tools Required
- 5mm Allen wrench [paid link]
- Cable cutters
- 3mm Allen wrench [paid link]
- 10mm wrench
- New cable (Campagnolo 11-speed cable)
- Cable housing (optional)
- Lubricant or grease
- Chain tool (optional for easier access)
Preparation: Assessing the Cable and Front Derailleur
Before starting the replacement process, it’s important to inspect the condition of your cable and its housing. If the housing is frayed or worn, it’s advisable to replace it as well to maintain optimal shifting performance. Additionally, ensure that the front derailleur itself is properly adjusted and clean.
- Shift to the Small Chainring: Begin by shifting the front derailleur to the small chainring, as this reduces tension on the cable, making it easier to remove.
- Release the Tension on the Cable: Use the 3mm Allen wrench [paid link] to loosen the set screw on the front derailleur where the cable is anchored. Once loose, gently pull the cable out of the derailleur.
Removing the Old Cable
- Disconnect the Cable from the Lever: If the cable is still connected to the shifter, shift the lever to the highest gear on the front, and then disconnect the cable from the shifter. Most Campagnolo systems have a clamp that holds the cable in place—loosen this clamp to free the cable.
- Remove the Cable from the Housing: If you’re replacing the housing, slide the cable through the housing. If the housing is still in good condition, you can leave it in place but ensure that the cable runs freely.
Preparing the New Cable
- Cut the New Cable to Length: Before installing the new cable, measure it against the old one to determine the correct length. Cut the new cable using cable cutters, making sure the end is clean and straight to avoid damaging the housing.
- Lubricate the New Cable: Apply a light layer of lubricant or grease to the cable. This reduces friction as the cable moves through the housing, which helps with smoother shifting and longer cable life.
Installing the New Cable
- Insert the Cable into the Housing: If you are replacing the housing, thread the new cable through the housing and ensure it runs smoothly without any kinks. If the housing is staying in place, simply thread the new cable through it.
- Anchor the Cable to the Front Derailleur: Once the cable is properly threaded, thread the cable into the front derailleur and secure it by tightening the set screw with the 3mm Allen wrench. Ensure that the cable is tight and doesn’t have any slack.
Final Adjustments
- Reattach the Cable to the Shifter: Now, move to the shifter and reattach the cable to the clamp or anchor point. Tighten it securely to ensure proper engagement when shifting.
- Adjust the Front Derailleur: With the cable in place, shift to the small chainring, and check the alignment of the front derailleur. If necessary, adjust the limit screws (located on the derailleur) to ensure that the derailleur does not overshift or undershift.
Tuning the Cable Tension
- Set the Proper Tension: To set the correct cable tension, shift to the large chainring and adjust the barrel adjuster on the front derailleur or shifter. Fine-tune the tension so that the front derailleur moves smoothly when shifting between chainrings.
- Test the Shifting Performance: Shift through all the gears, both up and down, to ensure that the front derailleur shifts smoothly and without hesitation. If you notice any skipping or hesitation, further adjust the cable tension or limit screws as needed.
Conclusion
Replacing the cable on your Campagnolo Chorus 11s [paid link] front derailleur is an essential maintenance task that can greatly improve shifting performance and drivetrain longevity. By following these steps, you can ensure that your front derailleur operates with precision and efficiency, giving you a smooth and reliable riding experience.
