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 Colin Miles is a great schooling bit with a wide center piece creating greater tongue pressure and reducing bar pressure. The rings give the horse something to play with and help keep the horses attention on the bit. 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. Mouthpiece This particular joint exerts more pressure than the Control Plate or Elliptical.
