5"(127mm) sweet iron medium port hinged mouth with copper inlays. 7" (177mm) antiqued shanks with the "Swivel Free System". Trimmed with stainless steel dots and engraved silver coloured plates. A specialized bit that isolates individually the shoulders of a broke horse. This bit also prevents the "over-tuck effect". Great for performance horses, barrel racers, team ropers, pole benders etc. Moderate to strong effect.
