The gears on the front of the bike are never referred to as gears but as "chainrings", though they might more accurately be described as disks. The gears on the back of the bike are called gears, not rings or disks. There are several of them and as a group they are referred to as a cassette. There may be a couple gears, err, chainrings up front too, but they are not called a cassette. No group of gears is called a "group set", that is something else (don't ask).
Oh, and that wheel on the back with all the gears on it that must be set in motion by the gears, err chainrings up front is called the "free wheel". The wheel on the front of the bike that turns freely in either direction is not called the free wheel.
It's only a freewheel if it's not a freehub. And my trash-found mtb came with two free wheels, a frame, and other junk.
