JHL Gag Cheeks Pair. These are needed to correctly use a Gag Bit. They have billeted fastenings to ease the fitting for the rider, and the high quality leather is durable, ensuring value for money. Leather Gag Cheeks are better than those made from rope as the action is slower, making the bit less severe. One size fits most cob and full-size bridles. Can be attached to a 3/4'' cheek piece.
