The seven-style shank prevents the horse from lipping the bit. The chain mouthpiece is actually quite mild and a useful training tool. The chain conforms to the shape of the horses mouth, applying mild tongue and bar pressure. This mouthpiece works well on horses in any western discipline.

Mouth: 5 1/4", Cheek: 7
 
NOTE: This bit will rust when exposed to moisture. This creates a sweet taste in the horses mouth and promotes salivation.
