The loose-ring has a circular ring which may rotate around on the mouthpiece. The sliding makes it more difficult for the horse to tighten against it, promoting relaxation and chewing from the horse. The loose-ring therefore keeps the bit more mobile than any other ring type. Loose rings are popular for training young horses, as the action is mild and allows for movement. The loose ring is the most common bit seen at the lower levels of dressage. It is also seen through all the levels of eventing (especially in the dressage phase), and is a common bit for race horses and show jumpers.
