Developed by SPRENGER in cooperation with Lisa Wilcox and Ernst Hoyos. The KK ULTRA mouthpiece with the middle link turned forward by 45 degrees provides gentle but effective communication with the horse. The additional feature of the WH ULTRA bits is a unique roller in the center section that brings an even better focus for the horse onto the tongue.

The WH ULTRA is highly recommended for horses that are unresponsive to the rein aids. The tongue is gently stimulated to utilize its highly sensitive sense of touch in an incomparable way. The horse gets relaxed and stays in better balance while becoming more responsive to the rein aids of the rider.
