AJR Textured Wilson BitThis bit features four loose rings; two attached to each end of the mouthpiece and two additional rings on the inside. The cheek pieces of the bridle are attached to the inside rings while the reins are attached to the outside rings. The textured mouth pieces prevent the horse from leaning on the bit. This design works with a squeezing action on the cheeks rather than on the corners of the mouth. Material: Carbon Steel Size: 135mm Mouthpiece
