Polo style bit for dressage with movable mouthpiece and leg. The movement band of the bit measures 30 mm from end to end. Made of high quality hand polished stainless steel. The design with the sliding mouthpiece and shanks allows for a more refined and flexible contact and communication with the horse. The vertical slide of the mouthpiece (30 mm) helps to relieve immediate pressure on the bars of the mouth whenever the horse yields to the pressure, promoting jaw relaxation. The long shanks (127 mm) offer superior leverage, suitable for experienced riders looking for precise and subtle control." Mouthpiece thickness 14 mm Total leg length: 127 mm
