The Shires Equestrian Blue Sweet Iron Double Jointed Lozenge Hanging Cheek Baucher Bit adds a little bit of poll pressure to encourage flexion. The brass alloy double joint effectively distributes pressure over both the tongue and the bars of the mouth to encourage mouthing and contact. The mouthpiece is 13mm thick, and the cheeks are 110mm tall. The blue sweet iron mouthpiece oxidizes easily to create warmth with a sweet taste to increase salivation and bit acceptance. Please note the blue colour will fade with use. Stainless steel cheeks for durability and rust resistance.
