The full rotary movement of the Ky Rotary Bits mouthpiece is not restricted like a conventional jointed bit.

More comfort for your horse with a perfectally centered ball allows the bit to rotate freely 360 degrees which enables each side of the bit to turn independently of each other.

More Rider control with the bit fitting centered in the horses mouth due to the mouth piece being equal lengths (check out tyour current bit and you will notice the mouth pieces are not the same length)
