7 inch Cheeks, 5 inch Mouth. Small Chain Mouth. Designed by a leading barrel racing trainer. Excellent training or performance bit. Long gag action delivers plenty of lift as well as control. Rope nose conforms well and works on the bridge of the nose for rate and control. Chain mouth is superior in this bit to lessen the bar pressure and add tongue pressure to help set horse's head and help provide the flex you need to turn your horse at the performance level.
