I would agree, 2 stage reduction appears to be consistent with the render
here. I'm not sure if it is all chain though or a belt and then a chain as the bottom circle in the render doesn't have any teeth.
EDIT: although that doesn't mean a whole lot, I would guess it's far easier to draw the gear like that if you are making it yourself and not using a premade file.
