The Bombers Liverpool Mullen driving bit is crafted from a lightweight, non-metal composite material, making it ideal for horses that are sensitive to metal. The hinged mullen mouthpiece offers a mild, consistent action that promotes relaxation and encourages salivation. This bit is especially useful for horses that dislike traditional materials. If minor damage occurs, the bit can be lightly filed for extended use. It’s a comfortable, functional, and rider-friendly choice for drivers who prioritize sensitivity and bit hygiene.
