The gag bit is a type of bit for a horse. Because the cheek piece and reins attach to different rings (instead of freely moving on the same ring, like in a snaffle bit) there is leverage action. Severity of leverage action depends on where the reins attach. For example, in a Dutch Gag, the further the rein attachment from the mouthpiece the greater the leverage. The gag bit is related to a Pelham bit and a double bridle but the gag bit has no curb strap.
