The MB 01 is the Myler alternative to the traditional single-jointed mouthpiece commonly used in snaffle bits. The MB 01 rotates onto the tongue to apply concentrated tongue pressure at the center barrel, but because the mouthpiece is curved, it wraps around the bars and lips instead of pinching. The barrel in the center applies approximately the same pressure on the tongue as a traditional single-jointed mouthpiece. However, the barrel distributes the pressure more kindly and allows for each side of the bit to be used independently.

Notes: The mouthpiece is similar to the MB 02 but the center barrel of the MB 01 is narrower, which concentrates pressure on the center of the tongue more than the MB 02. For more tongue relief, step up to the MB 04.
The loose ring is a simple stainless steel "O" shape where both the bridle and mouthpiece have no fixed point of attachment but slide freely around the ring. The loose ring allows a lot of play as the mouthpiece slides freely around the ring.
Size: 3" ring
Discipline: English or Western
Notes: The loose ring is generally considered one of the most non-interfering cheek pieces because the mouthpiece slides freely around the ring. However the play in the mouthpiece can make it difficult for a horse to find your hands as the mouthpiece is in continual motion. The movement of the mouthpiece can also exaggerate or create a busy mouth in young or anxious horses. It is best suited for more advanced horses fully schooled in leg and seat aids as well as rein aids.
