This guide covers everything you need to install, adjust, and maintain your Super Record WRL 12s [paid link] rear derailleur, including troubleshooting tips for common issues.

Tools Required [paid links]

Before beginning, ensure you have the following tools:

  • Allen wrenches
  • Torque wrench (for precise tightening)
  • Campagnolo UT-DB010 derailleur hanger alignment tool (optional but recommended)
  • Chain tool
  • Campagnolo EPS charger (for battery check and charging)
  • Clean rag and degreaser (for maintenance)
  • Lubricant suitable for electronic derailleurs

Step-by-Step Installation of the Super Record WRL 12s Rear Derailleur

1. Preparing the Frame and Hanger

Before installing the rear derailleur, ensure the derailleur hanger is straight. A misaligned hanger can cause shifting issues. Use a hanger alignment tool to check and adjust if necessary.

  1. Remove the old derailleur (if applicable).
  2. Clean the mounting area and check for damage.
  3. Align the hanger using the UT-DB010 tool if needed.

2. Attaching the Rear Derailleur

Unlike mechanical derailleurs, the Super Record WRL 12s [paid link] does not require a derailleur cable, simplifying installation.

  1. Position the derailleur on the hanger.
  2. Insert the mounting bolt and tighten using a 5mm hex key [paid link] to 8-10Nm torque.
  3. Check for firm attachment without over-tightening.

3. Pairing with the Wireless System

Since the Super Record WRL 12s is an electronic groupset, it requires pairing with the system.

  1. Press and hold the pairing button on the derailleur for three seconds until the LED blinks.
  2. Press the pairing button on the shift levers to connect.
  3. Confirm pairing success by shifting through gears.

4. Installing the Chain

The chain length should be set correctly for smooth shifting:

  1. Wrap the chain around the largest cog and largest chainring without passing through the derailleur.
  2. Add two extra links to determine the proper length.
  3. Use a chain tool to cut and install the chain.
  4. Secure the quick link and check tension.

Adjusting the Super Record WRL 12s Rear Derailleur

1. Setting the High and Low Limit Screws

The Super Record WRL 12s features traditional limit screws to prevent the derailleur from moving too far in either direction.

  1. Shift to the smallest cog and adjust the H-limit screw until the jockey wheel aligns with the cog.
  2. Shift to the largest cog and adjust the L-limit screw similarly.

2. Fine-Tuning the Indexing

If shifting feels off, use the micro-adjustment function:

  1. Shift through all gears, noting any hesitation or noise.
  2. Enter micro-adjust mode by holding the shift button.
  3. Tap the shift button to make small 1mm adjustments until shifting is crisp.

3. Checking B-Screw Adjustment

The B-screw controls derailleur clearance from the cassette.

  1. Shift to the largest cog and ensure a 5-7mm gap between the upper jockey wheel and cog.
  2. Adjust the B-screw if needed to optimize performance.

Maintaining the Super Record WRL 12s Rear Derailleur

Regular maintenance keeps your derailleur shifting smoothly.

1. Cleaning and Lubrication

  • Wipe down the derailleur after every ride using a clean rag.
  • Use degreaser to remove buildup on jockey wheels.
  • Apply light lubricant to pivot points to maintain smooth operation.

2. Battery Management

  • Charge the Super Record WRL 12s battery every 25-30 hours of riding.
  • Store the battery in a dry, temperature-controlled environment when not in use.

3. Checking for Wear

  • Inspect jockey wheels for wear or dirt buildup.
  • Ensure the derailleur body has no loose bolts or visible damage.
  • Check firmware updates via the Campagnolo app.

Troubleshooting Common Issues

Shifting Feels Slow or Unresponsive

  • Check if the battery needs charging.
  • Ensure the limit screws are correctly set.
  • Perform micro-adjustments to refine shifting.

Chain Skips or Jumps

  • Inspect for chain wear and replace if needed.
  • Verify the B-screw adjustment for proper clearance.

Wireless Connection Issues

  • Try re-pairing the derailleur with the shift levers.
  • Check for firmware updates via the Campagnolo app.

Conclusion

Proper installation, adjustment, and maintenance of the Super Record WRL 12s rear derailleur ensure smooth, reliable shifting for your rides. Whether you’re setting it up for the first time or fine-tuning its performance, following these steps will keep your drivetrain in top condition.
