Diamond R 3 in. Ported Roller Stainless Steel Dee Ring Bit, 3 in. Cheek, 5 in. Mouth, Stage B

This Diamond R 3 in. Ported Roller Stainless Steel Dee Ring Bit provides plenty of room for the horse's tongue to pass underneath, and when engaged does not rotate onto the tongue. The center barrel has limited movement to prevent the bit from scissoring down into the tongue or up into the palate. The copper roller provides some movement helping to pacify the nervous horse.
