This bradoon is part of Herm Sprenger's WH Ultra line. These bits have the same middle link as the KK Ultras with an added roller in the center which brings more focus and stimulation to the horse's tongue. Highly recommended for horse's that are unresponsive to rein aids, they will relax and stay focused on that roller, which prevents from becoming easily distracted.
We're riders ourselves, so we understand that bit fitting is not always easy and can get a bit confusing. We would be happy to help you, please call or email us with any questions; we are your friendly neighborhood tack shop online.
