Replacing the cable on your Campagnolo Record 11s Disc Brake [paid link] front derailleur is an essential maintenance task that can significantly impact the performance of your shifting system. Over time, cables stretch, wear down, and corrode, leading to poor shifting performance or complete derailleur failure. By replacing the cable, you can restore optimal shifting performance and ensure your bike performs at its best.

Tools Required

  • 5mm Allen wrench [paid link]
  • Cable cutter
  • Flathead screwdriver
  • 2mm Allen wrench [paid link] (for adjusting limit screws)
  • 10mm wrench (for the cable anchor bolt)
  • Lubricant for the new cable
  • New derailleur cable
  • Electrical tape (optional)

Preparing for Cable Replacement

Before beginning the cable replacement, it’s important to properly prepare your bike and workspace.

  1. Shift to the Smallest Chainring and Cog: To relieve tension on the derailleur and cable, shift to the smallest chainring and cog. This makes it easier to disconnect the cable from the derailleur.
  2. Place the Bike in a Stand: Use a bike repair stand to keep the bike stable and accessible throughout the process.

Step-by-Step Guide to Replacing the Cable

Step 1: Remove the Old Cable

  1. Loosen the Cable Anchor Bolt: Using a 10mm wrench, locate the cable anchor bolt on the front derailleur and loosen it. This will release the tension on the cable.
  2. Disconnect the Cable: Once the bolt is loose, pull the cable out of the derailleur. Be careful not to lose any parts, such as washers or springs, which may be attached to the cable anchor.
  3. Remove the Cable from the Housing: Starting from the derailleur, slide the cable out of its housing all the way to the shifter. You may need to remove or unclip the cable from various cable guides along the frame.

Step 2: Install the New Cable

  1. Prepare the New Cable: Uncoil the new derailleur cable and apply a small amount of lubricant to ensure smooth movement through the housing. This also helps prevent rust and corrosion over time.
  2. Feed the Cable into the Housing: Starting at the shifter, carefully thread the new cable into the housing. Push it all the way through until it emerges near the front derailleur.
  3. Thread the Cable Through the Derailleur: Once the cable reaches the derailleur, thread it through the derailleur’s cable guide and pull it tight.

Step 3: Secure the Cable at the Derailleur

  1. Insert the Cable into the Anchor Bolt: Pull the cable taut to eliminate slack, then insert it into the cable anchor on the front derailleur.
  2. Tighten the Anchor Bolt: Use the 10mm wrench to tighten the cable anchor bolt securely. Ensure the cable is tight, but not over-tensioned, as this can affect shifting quality.

Step 4: Adjust the Shifting

Once the cable is secured, it’s important to adjust the shifting to ensure smooth operation.

  1. Check the Front Derailleur Position: Ensure the front derailleur is positioned correctly over the chainring. It should be slightly above the largest chainring, but not too high to interfere with the chain.
  2. Adjust the Limit Screws: Use a 2mm Allen wrench [paid link] to adjust the limit screws on the front derailleur. These screws control the derailleur’s travel range and prevent the chain from overshooting or getting stuck. Adjust the “high” and “low” limit screws to ensure the derailleur moves freely between the chainrings.
  3. Test the Shifting: Shift through all the gears, making sure the front derailleur moves smoothly between the chainrings. If shifting is sluggish or the derailleur struggles to move, recheck the cable tension and limit screw settings.

Step 5: Trim the Excess Cable

Once the shifting is properly adjusted, you will have excess cable protruding from the anchor bolt.

  1. Trim the Cable: Use a cable cutter to trim the excess cable, leaving just enough length to attach a cable end cap.
  2. Install the Cable End Cap: Place a cable end cap over the cut cable to prevent fraying. Crimp the cap with your cable cutter or pliers to secure it.

Step 6: Final Check

After the installation is complete, give the bike a thorough inspection. Shift through the gears a few times while observing the derailleur’s movement. If everything shifts smoothly and quietly, you’ve successfully replaced the cable.

Conclusion

Replacing the cable on your Campagnolo Record 11s Disc Brake [paid link] front derailleur is a straightforward process that can dramatically improve shifting performance. By following these steps, you ensure that your derailleur operates smoothly and efficiently, enhancing your riding experience. Regular maintenance, including cable replacement, is essential for the longevity of your drivetrain components and optimal bike performance.
