Shank swivels from the mouthpiece to enhance lateral control. Adds some tongue pressure to help break a horse over at the poll for better head set. Offers more control than a regular medium port. Excellent for even the most nervous horses with no pressure on the bars. Flat mouthpiece lies across the tongue.
Shanks work independently, applying pressure to the curb chain.
Great for ropers and barrel racers. Unique design of the curb portion applies severe pressure to horse's lower chin for lots of whoa. Swivel cheeks allow rider to lead horse off to the side much better than the old fast stop or quick stop. Slightly longer purchase and cheek add control for rate and supple turns. Works off tongue, lip, bar and curb pressure.
