Level: Two, Three
Design: Curved mouthpiece with two hinges and upward-curved piece in the center. Port measures 1½". 5" mouth.
• Downward pressure on tongue and bars
• Collapses on outside of bars
Usage: Rewards the horse with a "comfort zone" when relaxed at the poll. Good bit for collection and stopping. Works well for spoiled horses and horses who run through the bit. A good choice for horses with low palates.
Design: A length of metal with two rings and fixed mouhtpiece attachment. The top ring is for headstall and curb strap attachment; the bottom ring is for the reins. The length of metal below the mouthpiece is round and bent at an angle toward the rider's hands. The top, or purchase, is angled away from the horse and the ring is squared. 7" cheek. 6½" shank.
Function: Shanks are used for leverage and, typically, with a curb strap or chain. Depending upon the mouthpiece used, backward and upward pressure on the reins transfers into downward pressure on the poll, pressure on the curb, and forward and downward pressure on the palate. The tops, or purchases are bent away from the horse to prevent discomfort or rubbing.
Usage: Used in Western disciplines.
