The Herm Sprenger KK Ultra Sensogan Loose Ring provides an incomparable precise contact between rider and horse. KK Ultra Bits were developed after extensive research at the Veterinary University in Hanover, Germany. The results revealed some new findings: the interior volume of the mouth is less than previously thought and the palate is smaller and flatter. Therefore, the space left for a bit is quite limited. KK Ultra bits take advantage of the research and of the exceptional sensitivity of the tongue by shortening the link and turning it 45 degrees. These two changes caused the link to rest fully on the tongue without squeezing or pinching it. With the link resting fully on the tongue the sense of touch is utilized and clear instructions can be passed through the reins. Made in Germany.
