Bombers Loose Ring Bomber Blue Mullen. The Mullen distributes pressure evenly over all the structures of the mouth, while this avoids pressure points, it does make the Mullen a fairly strong bit. The material used allows the bit to remain light and it encourages salivation. It is particularly well suited to horses that object to metal mouth pieces. An internal stainless steel chain covered with a bespoke non-toxic, UV resistant PVC tube offering an exceptionally soft and evenly distributed pressure over tongue and bars. Especially good for the horse that objects to metal. This is Bomber’s version of the vulcanite, it is lighter an stronger and would be recommended for the older horses. Bomber Blue Mullen belongs to the category first at the Bombers bit category; Solid SOLID: The mouthpiece is fixed between cheek pieces, optionally offering tongue relief in the form of a port. When used in conjunction with a fixed cheekpiece it should fit tightly to eliminate and sideward movement. CHEEKPIECE - LOOSE RING - Bomber’s preferred cheekpiece.

The cheekpiece ring size is about Ø67mm for bit width 90-115mm and about Ø78mm for bit width 120-160mm.
