The gag bit gives precise action to your horse's balance. It obliges the horse to lift his whole front end and therefore puts his weight on the back end. It is generally used on horses which are quite heavy and puts much weight on the shoulders. A ring bit is generally associated with a snaffle bit. The bit ring is attached to the mouth piece. It has an effect on the action of the bit so should be considered when choosing a bit even though the mouth piece has a greater effect than the ring itself. Bits included in the ring bit category are: snaffle bits, bradoons and gag bits.
