Bombers Bit Petros Williams
The Williams cheekpiece allows for multiple rein positions. If connected to the main ring the bit acts as a loose ring, but when connected to the bottom ring it promotes pole flexion by creating more positive poll pressure. The Williams cheekpiece helps to prevent drifting.
The Petros mouthpieces rotate preventing the horse taking hold of the bit. Often good for a horse that leans or tries to take hold of the bit.
