Jump'in Large Ring Gag Bit with RollersWe love this Large Ring Gag Bit with Rollers, because it helps with our horse's balance. This bit makes the horse rebalance and transfer its weight onto its hindquarters. The larger the rings, the stronger the gag action is. The rollers have a relaxing effect on the horse's mouth. This bit needs special cheek pieces and can be used directly with two reins, with bit loops or with four reins. Rinse the bit after each use to prevent any residue deposit
