This cheek has a 2 3/4" purchase with a 4 3/4" shank. The shank is swept back, like the 6" model, but to a lesser degree, which offers more leverage and control. The purchase/shank alignment ratio creates more pressure to all points of contact than the 7 1/2" design. When properly used and adjusted, it is still considered a mild cheek, but one with plenty of leverage to control the horse at increased speeds.
