In bicycle terminology, what does 'Components' refer to?

• A. Aesthetic parts of the bicycle
• B. Mechanical Parts of the Bicycle
• C. Electrical systems only
• D. Frame and fork assemblies

Answer: (B)

Components are the parts that actually make the bike work—the mechanical pieces you service or replace to make it go, stop, steer, and roll. This includes the drivetrain (cranks, chain, gears, derailleurs, chainrings), brakes and levers, handlebars and stems, wheels and tires, pedals, seat post and saddle, and related hardware. Cosmetic details aren’t components, and saying “electrical systems only” misses the broad range of mechanical parts that constitute a bike. The frame and fork are the structural backbone, not what riders typically refer to when talking about components.
