The Campagnolo Record HO 11s [paid link] rear derailleur is a high-performance component designed for precise and smooth shifting on road bikes. With its advanced design, including a longer pulley cage and optimized geometry, it offers improved compatibility with modern frame designs. However, proper installation, adjustment, and maintenance are essential to keep it performing at its best.

This guide provides a step-by-step approach to setting up and maintaining the Record HO 11s [paid link] rear derailleur, troubleshooting common issues, and ensuring long-term reliability.


Tools Required [paid links]

Before starting, gather the following tools:


Step 1: Installing the Record HO 11s Rear Derailleur

1.1 Preparing the Frame and Hanger

  • Ensure the derailleur hanger is straight using a derailleur hanger alignment tool.
  • Clean the hanger threads and apply a small amount of grease to prevent corrosion.

1.2 Mounting the Derailleur

  • Use a 5mm hex key [paid link] to attach the derailleur to the hanger, tightening it to 8–10 Nm.
  • Ensure the B-screw (top adjustment screw) is in a neutral position to allow for further adjustments later.

1.3 Routing and Securing the Cable

  • Shift the shifters to the smallest sprocket position.
  • Thread the shift cable through the housing and into the derailleur clamp.
  • Pull the cable taut and secure it using a 4mm hex key, tightening to 5–6 Nm.

Step 2: Adjusting the Record HO 11s Rear Derailleur

2.1 Setting the High (H) and Low (L) Limit Screws

  • Rotate the high limit (H) screw until the jockey wheel aligns perfectly with the smallest cog.
  • Shift to the largest cog and adjust the low limit (L) screw to ensure the jockey wheel is aligned.

2.2 B-Tension Adjustment

  • Adjust the B-tension screw to set the correct chain gap (distance between the top pulley and the largest sprocket).
  • Ensure the derailleur moves smoothly and does not overextend toward the spokes.

2.3 Fine-Tuning the Indexing

  • Shift through all gears and adjust cable tension using the barrel adjuster.
  • If shifting feels sluggish, add tension; if it skips gears, reduce tension slightly.

Step 3: Maintaining the Record HO 11s Rear Derailleur

3.1 Cleaning and Lubrication

  • Clean the derailleur with a degreaser and a soft brush.
  • Apply a light lubricant to the pivot points and jockey wheels.

3.2 Checking for Wear

  • Inspect the jockey wheels for excessive wear and replace if necessary.
  • Ensure the derailleur hanger remains straight after any impact.

3.3 Replacing the Shift Cable

  • Remove the old cable by loosening the clamp bolt.
  • Insert a new cable, ensuring smooth routing through the housing.
  • Secure the new cable and adjust indexing as needed.

Troubleshooting Common Issues

4.1 Shifting Hesitation or Skipping Gears

  • Check for cable tension issues; adjust using the barrel adjuster.
  • Ensure the derailleur hanger is straight.

4.2 Excessive Noise or Chain Rub

  • Verify limit screw settings and adjust as needed.
  • Lubricate the jockey wheels and chain to reduce friction.

4.3 Chain Dropping Between Gears

  • Ensure the derailleur is aligned correctly with the cassette.
  • Check the B-tension screw setting for proper chain tension.

Conclusion

A properly installed and maintained Campagnolo Record HO 11s [paid link] rear derailleur ensures smooth, precise shifting and extends the lifespan of your drivetrain. By following these steps for installation, adjustment, and maintenance, you can optimize your bike’s performance and avoid common shifting issues.
