8 inch Cheeks, 5 inch Mouth. 3/8 inch 3-Piece Twisted Wire Dog Bone Snaffle. Used by barrel racers and trainers. Ridden with a tight curb, this bit has good rate, lots of flex but light enough to keep your horse moving in turns. Mouthpiece adds some bite for stronger running horses. Loosen the curb for colts or slow work for plenty of flex.
