Bits tend to fit the riders hand as much as the horse mouth. Most important is timing, when you pull and when you do not. Knowing your hands and style will help you choose a bit that your horse will accept and respect. Merrill barrel racing bits are designed to send a clear and firm signal without offending the horse.
Merrill Bits are handcrafted in the USA.
Hackamore (Hack) has no mouthpiece and uses pressure on the face and nose when communicating to the horse with your hands.
