10” cheeks, 5.5” mouth. Twisted sweet iron broken mouthpiece with gag cheeks. Molly’s favorite bit to run a horse that tends to overrun the first barrel. High control to get tight barrel turns and well accepted by horses that are not used to so much control. Curved mouthpiece and shank gag effect has give. Adjust curb chain a little looser for first ride, then tighten for more control.
