40514-78 KK loose ring 12 mm single jointed - Sensogan 70mm rings

the rein aid pressure that is exerted on the tongue-edges and lower jaw is more intense compared to normal single jointed bits
for strong horses that are unresponsive to normal double or single jointed bit
for horses that tend to lean on the bit, using the reins as "5th leg"

The 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.
