In the American west, a metal ring fastened to a spade bit at the highest point of the bit mouthpiece passing through the horse's mouth, and surrounded the lower jaw was called a "ring bit." This design was more common in the Southwest than in the Northwest, and gradually disappeared from both areas, but remained in general use in Mexico. Today, the ring bit is most common in horse racing, and usually has a jointed snaffle bit, with the ring linked to the bit rings or lower cheeks.
