CHELETENHAM GAG OR RUNNING GAG BIT
The flat ring, eggbutt-sided single-joint gag snaffle is a specialized bit designed for precise control during riding. Its unique construction features holes in the rings, allowing the rolled leather or cord cheek of a special bridle head to pass through the bit end. Positioned in a small ring that takes the reins, this setup enables the bit to fit normally when no pressure is applied. However, when the reins are pulled, the rolled ends slide through the bit, exerting upward pressure and creating a vice-like effect between the poll and corners of the mouth. To provide additional control, a second rein can be attached conventionally. Considered one of the gentler gags, it acts on the tongue, bars, corners of the mouth, and poll, offering effective communication while ensuring the horse's comfort and responsiveness.
