2–5 inches in diameter, most commonly ranging in the 2.5–3 inch range that is legal for horse show competition. Rings for bradoons are smaller than those used on a plain snaffle. Rings may be larger on gag bits, especially if the rider wishes to increase the severity. Thickness ranges from 10 to 23 mm, with most found at 15 mm. Mouthpiece: comes in many mouthpiece sizes, with 5" being the most standard size for the average horse, with a range from 3" for miniature horses to over 6 inches for a large warmblood or a draft horse. Various metals are used, and mouthpieces may be made in almost any type (see bit mouthpiece). Uses: One of the three most popular designs, loose rings are often used for training young horses, as the action is mild and the loose movement of the ring provides warning prior to rein pressure. The loose ring is the most common bit seen at the lower levels of dressage and on junior horses in western riding disciplines. It is also seen through all the levels of eventing (especially in the dressage phase), and is a common bit for race horses and some show jumpers. Eggbutt/Barrel head Types of Bits: Found on snaffles, gag bits, and bradoons. Pelham bits also usually have an eggbutt design for the snaffle ring on the shank. Action: the eggbutt has a slightly oval (egglike) shape, and consists of a round outer ring attached to a more upright, straighter cheek which is fixed to the mouthpiece. The ring can move back and forth where it attached to the cheek, but does not rotate like the loose-ring, and so is more stable in the horse's mouth, and not as fixed as the other types of rings. Advantages: This is a mild bit and will not pinch like the loose ring. Disadvantages: It is more easily pulled through the mouth than a bit with cheeks. Size and Thickness of Rings: The rings range from rounder and thinner to wider and flatter in shape. Their thickness varies from 10-23mm, and most are about 3" across. Mouthpiece: This is also a popular bit that comes in many sizes, ranging from 3–6.5 inches. The mouthpiece is usually solid, but may be hollow mouthed. Uses: Eggbutts are overall one of the most popular ring designs, less common in the dressage arena than loose-rings, more often seen in show
