Key Features The Loose Ring allow for immediate release and relief from tongue and bar pressure. The bit is immediately reset to a neutral position in the horse’s mouth. The Waterford Barrel has a few smooth flexible cylindrical components which spread the pressure points making it a light mouthpiece. Cheekpiece Bomber’s preferred cheekpiece. The cheekpiece is available in 3 sizes; large, standard and a slightly smaller model for a pony. Bomber highly recommends using a bit strap on a loose ring, as it stabilizes and minimizes the mouthpiece sliding through the mouth. Consider bit rubbers as a precaution.
