BB30
BB30 is a widely recognized bottom bracket standard used in bicycle manufacturing and repair. A bottom bracket is the part of a bicycle that allows the pedal cranks to spin smoothly. BB30 specifically refers to a design that was created to make bikes lighter and stiffer. When this term appears in resumes or job descriptions, it indicates experience with modern bicycle repair standards and high-end bike maintenance. Similar standards include PF30 and BSA, but BB30 is often considered a benchmark skill for bicycle mechanics.
