The Twisted Wire Buster Roller bit from Bombers Bits offers a strong mouthpiece, which can be useful for horses that require extra control, along with full cheeks to assist with steering.
The twists in the mouthpiece have edges that cause additional pressure points on the tongue and bars of the mouth, and also act on the lips. Combined with the thin mouthpiece, this offers the rider much more control than a smooth bit, and can help to prevent the horse from leaning as well as aiding in lifting the forehand. It is recommended that twisted wire bits are only used by experienced riders.
The 40mm roller link in the centre encourages the horse to play with the roller and soften to the contact, as well as increasing tongue and bar pressure. The blue sweet iron mouthpiece oxidises easily, creating a warm, sweet taste in the horse's mouth. This encourages the horse to salivate, gently mouth the bit and relax his jaw, and can help horses who have difficulty accepting conventional metal bits.
