Di2
Di2 (Digital Integrated Intelligence) is Shimano's electronic gear-shifting system for bicycles. Instead of traditional cable-operated shifting, it uses electronic buttons and motors to change gears. Think of it like an automatic transmission for bicycles, but one that still lets riders choose when to shift. This technology is considered high-end and appears frequently in professional cycling and luxury bike repairs. When you see this term in resumes, it indicates experience with advanced bicycle components and electronic systems.
