The Myler English D-Ring with MB 01 twisted mouthpiece is a Level 1 bit intended for horses that are beginning training. The free-rotating barrel uses mostly tongue pressure and collapses onto the bars. The curved mouthpiece permits the horse to swallow more freely and distributes pressure evenly. Independent Side Movement™ allows the rider to isolate one side of the bit for bending, balancing or lifting a shoulder. The twist has smooth curves and is symmetrical on each side of the bit, applying mild bar pressure without any bite. Stainless steel with copper inlay. Condition: New Size: 5.5"
