Fix front derailleur chain rub by identifying the gear pattern, checking alignment and limits, then making the maker-approved cable adjustment.

Adjust a cable-operated rear derailleur by checking the drivetrain, limits, cable path, indexing, hanger, and pulley alignment in the maker's sequence.

Adjust mechanical bike gears by inspecting the drivetrain, setting derailleur limits from a baseline, then fine-tuning cable indexing one step at a time.
