4. Install the Chain: Thread the chain through the jockey wheels of the derailleur, ensuring that it runs smoothly across the gears.
5. Install the Rear Wheel: Place the rear wheel back into the dropouts and check the alignment. Make sure the wheel sits properly and the chain is tensioned correctly.
6. Connect the Derailleur to the Shift Cable: Using a 3mm Allen wrench, attach the shift cable to the derailleur’s cable anchor. Pull the cable tight and secure it.
7. Adjust the Limit Screws: Using a small screwdriver, adjust the high and low limit screws to prevent the derailleur from shifting beyond the smallest or largest cog.
8. Test Shifting: Shift through all gears to ensure the derailleur is moving freely and that the chain shifts smoothly between cogs.

Adjustment of the Campagnolo Record 12-Speed Rear Derailleur

Once the derailleur is installed, fine-tuning it is essential for precise and reliable shifting, especially in the demanding conditions of gravel terrain.

Key Adjustment Areas:

1. B-Tension Screw: The B-tension screw controls the distance between the jockey wheels and the cassette. For gravel riding, you may need to adjust this slightly to accommodate thicker tires, ensuring the derailleur does not rub against the cassette or fail to shift properly.
2. Shifting Precision: Ensure that the derailleur moves smoothly through all gear ranges. If it hesitates or skips, adjust the cable tension slightly using the barrel adjuster.
3. Limit Screw Calibration: Revisit the limit screws to make sure the derailleur does not overshoot on the large or small cog. This is especially important for gravel riding, where rough terrain can sometimes affect derailleur movement.
4. Cable Tension: Proper cable tension is crucial for smooth shifting. Check the shifting accuracy by testing the derailleur’s movement across all gears. Fine-tune the barrel adjuster until you achieve crisp shifts without skipping.

Maintenance of the Campagnolo Record 12-Speed Rear Derailleur

Maintaining the Campagnolo Record 12‑speed rear derailleur ensures longevity and performance, especially when riding on gravel where debris, mud, and harsh conditions can take a toll.

Regular Maintenance Tasks:

1. Clean the Derailleur: After each gravel ride, clean the derailleur to remove any dirt, sand, or grit [paid link] that could affect its movement. Use a soft brush and mild degreaser to gently scrub the derailleur.
2. Lubricate the Jockey Wheels: Regularly lubricate the jockey wheels to reduce friction. This helps prevent wear and ensures smooth shifting.
3. Inspect the Cable: Check the shift cable for fraying or wear, especially if you’re riding in abrasive conditions. Replace any damaged cables to avoid shifting issues.
4. Check for Chain Wear: Gravel riding can cause excessive wear on your chain. Use a chain checker tool to monitor chain wear and replace the chain as necessary to maintain smooth shifting.
5. Check Derailleur Alignment: Periodically inspect the derailleur for any misalignment caused by impacts or rough terrain. Realign the derailleur hanger if necessary.

Troubleshooting Common Set-Up Issues

Even with proper installation and maintenance, issues may arise, especially during gravel rides where terrain can challenge the derailleur’s performance. Below are common issues and their solutions.
