Derailleur
A derailleur is a crucial gear-changing mechanism found on most modern bicycles. It's the device that moves the chain between different gears, allowing cyclists to pedal comfortably at different speeds and on various terrains. When reading resumes in the bicycle repair industry, you'll often see experience with both front derailleurs (which move the chain between the front gears near the pedals) and rear derailleurs (which handle the back gears). This component is so important that expertise with derailleur adjustment and repair is often considered a fundamental skill for bicycle mechanics.
