This double-jointed ring bit is made from high-quality stainless steel combined with flexible plastic. As a result, the bits are stable yet particularly soft and horse-friendly. The plastic has a hardness rating of 90A and is FDA approved. This means that the material is free from solvents, contains no plasticizers, and is non-toxic. The bits can be used for all horses and are especially suitable for young horses, horses with sensitive mouths, and horses that have difficulty accepting other materials. The bit has a very gentle effect in the mouth. The thickness of the canon is 18 mm, and the diameter of the bit rings is 70 mm. A ring bit is a bit with separate bit rings. This type of bit is generally well accepted, as the canon sits relatively loosely in the mouth. In a double-jointed ring bit, the canon consists of three parts. The middle part of the canon lies flat on the tongue, creating more pressure on the tongue than with a single-jointed bit. The thicker the middle part, the greater the pressure on the tongue.
