The wider Barrel 30 concentrates pressure on the tongue and further limits the nutcracker action. When the rein is used this mouthpiece wraps across the tongue creating tongue pressure and taking pressure off the bars due to the lock up action. This bit exerts sharper pressure than the Elliptical due to the Barrel being smaller.
The Loose Ring allows for immediate release and relief from tongue and bar pressure which will reset the bit in the horses mouth.
All Bomber bits are made from blue sweet iron, because it oxidises easily, encourages salivation, helps bit acceptance and is warm and sweet. *Please note that due to the oxidisation the blue will fade with use.
