This bit is a great option for horses that like to be heavy in your hands and hang on the bit. This bit works like a snaffle with extra leverage. The main purpose of this bit is to lower the horses head through poll pressure, and to provide stronger control. The reins can be attached in a variety of ways. If the reins are attached to the main large ring the bit has the same effect as a loose ring snaffle, with slightly more poll pressure due to the cheek pieces attaching to the smaller top ring. When the reins are attached to the lower ring, the poll pressure is increased, giving the rider more control and putting more pressure on the mouth. This bit can also be used with multiple reins or connectors, softening the leverage/pressure. The roller link reduces nutcracker action, has a more even pressure over the bars, and allows independent control over the two sides of the mouth. The sweet iron mouthpiece and brass rollers encourage the horse to salivate, making the horse lighter in the rider's hands The central brass rings encourage the horse to mouthe the bit as well as reducing the nutcracker action. Slightly curved to be more comfortable in the horse's mouth and to allow extra space for the tongue
