A ring cheek piece introduces poll pressure as well as creating leverage on the mouthpiece, the 2 1/2 Ring version is the softest out of the 3 or 4 ring alternatives as the 1/2 ring softens the leverage on the mouthpiece and poll. The Elliptical is stronger than the Control Plate due to it concentrating pressure onto a smaller surface area. This bit will suit a horse that pushes the bit with its tongue. The horse will draw its head back and tuck its chin in, finding a better balance of control.
