On a freewheel, the coasting mechanism is built into the gears or cogset. “Freewheel” refers to the gear cluster as a whole, with the coasting mechanism inside.

The terms "freewheel" and "cassette" are often used interchangeably, an error that causes a lot of wasted time and money. Freewheels for Threaded Hubs: Traditional rear hubs came with a standardized set of threads to which a standard freewheel / sprocket cluster could be screwed on.
