The moulded preferred contact has cylindrical sides and is flat through the middle. The cylindrical sides flex onto the bottom bars and jaw, with the flattened centre section bending over the tongue. The centre tongue pad is an elongated circle, flattened and angled at 45 degrees to sit flush against the tongue and palate. The articulated ribs on either side of the tongue pad allow the cylindrical sides some independence, and the tongue pad some stability. Good for the horse that objects to metal or when you have tried every kind of bit without luck. The Bombers moulded material has been uniquely developed, to ensure 3 key attributes: texture, durability and comfort. As with all our steel components, the cable core and cheek piece will be covered by our lifetime guarantee.
