  6. Set the B-tension: Adjust the B-tension screw to ensure proper derailleur movement and clearance between the jockey wheels and the cassette.
  7. Test shifting: Use the shifters to test shifting performance. Adjust the barrel adjusters on the derailleur and shifter to fine-tune the cable tension.

Adjustment of the Super Record 12-speed Rear Derailleur

Proper adjustment is crucial to ensure smooth and precise shifting, especially on gravel terrain. The Super Record 12-speed Rear Derailleur uses a highly tuned shifting mechanism that requires precise alignment of the derailleur, chain, and cassette.

Adjustment Steps:

  1. Set derailleur limits: Begin by adjusting the high and low limit screws on the derailleur. The high limit screw determines how far the derailleur can shift to the smallest cog, while the low limit screw controls the largest cog.
  2. Check derailleur alignment: Ensure the derailleur is parallel to the cassette and that the jockey wheels are positioned correctly relative to the cogs. Misalignment can lead to skipping or shifting issues.
  3. Adjust cable tension: Use the barrel adjusters to fine-tune the cable tension. Turn the barrel clockwise to increase tension and counterclockwise to decrease tension. Proper cable tension ensures smooth shifting through all gears.
  4. Test shifting: Shift through all gears, ensuring smooth transitions. Make minor adjustments to the barrel adjusters if shifting is not crisp.

Maintenance of the Super Record 12-speed Rear Derailleur

Regular maintenance is essential for ensuring the longevity of the Super Record 12-speed Rear Derailleur, particularly when used in gravel riding conditions. The rough terrain can introduce more dirt, grit [paid link], and moisture, all of which can affect derailleur performance.

Maintenance Tips:

  • Clean regularly: After riding on gravel or muddy conditions, clean the derailleur and drivetrain components to remove dirt and debris. Use a degreaser and brush to clean the derailleur, chain, and cassette.
  • Lubricate the derailleur: Apply a light lubricant to the derailleur pivot points and jockey wheels to ensure smooth movement. Be cautious not to apply excessive lubrication, as it can attract dirt.
  • Inspect for wear: Periodically check the derailleur for signs of wear, such as cracked carbon fiber or worn-out jockey wheels. Replace any worn components immediately to prevent shifting issues.
  • Check derailleur hanger alignment: Since gravel riding can cause derailleur hangers to bend or shift, check the alignment regularly to prevent shifting problems.
  • Replace the chain: Use a chain checker tool to monitor chain wear. Replace the chain when it reaches the wear limit to prevent premature wear on the cassette and derailleur.

Troubleshooting Common Issues

Even with proper installation and adjustment, issues can arise with the Super Record 12-speed Rear Derailleur, particularly when used in challenging gravel environments.
