AJR Sport Leather Hinge Dee BitWe love the unique hinge mechanism of this Leather Hinge D Bit, which offers enhanced mobility and responsiveness unlike traditional jointed bits. This innovative hinge allows the two sections of the mouthpiece to move independently, providing clearer and more precise signals to the horse. This design effectively reduces the 'nutcracker' effect commonly associated with jointed bits, thereby minimizing the risk of pinching the horse's tongue or cheeks.
