kk pony loose ring snaffle bit single jt 12 mm sensogan metall 135 mmThe KK bits from SPRENGER transmit aids with exceptional precision: With a soft contact on the reins, they act like a regular single jointed bit, but when the horse leans on the reins, it feels targeted pressure on the edges of the tongue and the lower jaw. Even for horses with tongue issues, the KK bit is a good choice, supporting a fine, controlled communication between rider and horse.
