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 Bomber Blue is a unique bit which produces amazing results for the majority of horses. The mouthpiece is ported to give tongue relief. The nylon composite material is light in the mouth and encourages salivation. It is particularly well suited to horses that object to metal mouth pieces.
