The bit ring is the ring on the side of a horse's bit, particularly on a snaffle bit. It is used as a point of attachment for the cheekpieces of the bridle and for the reins. It also has an effect on the action of the bit. Therefore, the design of the ring is something to consider when choosing a bit for a horse, even though the bit mouthpiece generally has a greater effect than the ring.
Choices in bit rings can be found in direct pressure bits such as snaffle bits or bradoons. Leverage bits such as the pelham, and curb bit have a bit shank rather than a bit ring. (see bit shank). The Kimblewick has a unique design in that the side of the bit resembles a bit ring, but actually is a very short bit shank, as it applies leverage pressure to the mouthpiece.
Bit ring designs also are subject to fads. The loose ring is currently one of the most popular overall designs, but several years ago the eggbutt and dee-ring were quite common. There are also differences in the popularity of a given design from one discipline to another and from geographic region to the next.
Types of Bits: Found on snaffles, gag bits, and bradoons.
Action: The loose ring is 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. The ring will also rotate slightly before the bit mouthpiece adds pressure to the mouth, thus allowing it to give more signal than a more fixed bit.
Disadvantages: the loose ring may pinch the corners of the lips as it rotates, causing pain to the horse. This is especially a problem if the bit mouthpiece is too small. If this occurs, a bit guard may be used. The bit mouthpiece should be slightly wider (to accommodate the bit guard) should one be used; it is best if it is at least 1/2 inch wider than required by the horse's mouth. There are some horses that dislike the rattling noise of the loose ring. Additionally, the loose-ring is more easily pulled through the mouth than a bit with cheeks.
