Rowland 9mm SS Barrel Racing Bit With Curved shanks, Low Port Mouth having Copper Roller is a type of bit used primarily in barrel racing to give the rider more control and leverage over the horse.
The extended cheeks provide a more direct and clear signal to the horse when the rider uses the reins, making it easier to direct the horse's head and neck, especially beneficial for young or green horses learning to turn and respond to rein aids.
