HKM 3-Piece Boucher Bit w/Aurigan Center
This is a great value. For slightly more pressure on the horse's poll, many riders like to use a boucher, or hanging cheek style bit. This one is from HKM of Germany, is 16mm thick, with solid aurigan metal center to promote salivation and stainless cheeks. We stock many sizes and I have used this bit myself.
** for the size 5 1/2"; this is transposed from metric (actually is 135mm, which equates to between 5.25 and 5.5", but closer to 5.5")
