This bit consists of four rings: the top one where the cheek pieces attach and then three lower rings offering a variety of rein settings. There are also versions available with just two lower rings that some riders feel look neater. The cheek ring is often quite large and flat with all the rings in alignment underneath, and it has a variety of rein options which allows the rider to use one bit for a variety of situations, depending on how much control is required.
