BraidedNylon ConstructionStablize Long ShanksProtect Horse's MouthLoop to Loop Measures 6-1/2"BITTIEBit hobbles are used at the bottom of the shanks and attach to the rein rings. For one-handed riding, they help to stabilize longer shanks. They also help to protect the horse's mouth while roping by preventing the rope from getting between the shanks and catching one side, forcing one shank up and out.
