- Turn the barrel adjuster in quarter-turn increments
- Clockwise tightening reduces cable slack
- Counterclockwise loosening increases cable length
Setting Derailleur Limits
Limit screws prevent the chain from falling off the cassette. They control the derailleur’s range of motion. This ensures precise gear changes and protects your bike.
- Locate the high (H) and low (L) limit screws
- Adjust with the chain on the smallest and largest cogs
- Ensure the derailleur doesn’t overshoot the cassette
“Precision in derailleur adjustment can make the difference between a smooth ride and a frustrating experience.”
Fine-tuning Shift Performance
Achieving perfect gear indexing requires patience and careful adjustment. Start by checking your bike’s overall mechanical condition. Look for any wear or damage on shift cables.
