Key Features A ring cheek piece introduces poll pressure as well as creating leverage on the mouthpiece, the 2½ Ring version is the softest out of the 3 or 4 ring alternatives as the ½ ring softens the leverage on the mouthpiece and poll. A horse shaking its head when bit pressure is applied or trying to put its tongue over the bit are classic signs the horse has a sensitive tongue. With this in mind the McHardy was created, it has a medium port creating space for the tongue, relieving pressure. The Buster Roller in the middle increases bar pressure and as a result extends the head and brings the nose in giving more control. Cheekpiece The cheekpiece is available in 2 sizes, standard and a slightly smaller model for a pony.
