5" Cheeks Exciting new shank. Very nice colt bit for introducing curb pressure and low leverage. Cutters, Team Penners, Trail Riders, Reiners, and Barrel Racers have used this bit on horses with good mouths that don't need excessive control. The 3-piece snaffle is a very nice mouth and has more control than a 2-piece snaffle. Also adds some tongue pressure to help set horse's head. Copper roller acts as a pacifier for nervous horses.
