This bit features an arched mouthpiece that offers the horse more tongue room than a straight bar bit. The mouthpiece is reversible - with a smooth finish on one side and ribs on the other, to offer more or less severity.
It has fixed cheeks to prevent pinching of the lips, and a double link curb chain.  There are 2 slots in the shank to allow adjustment to the severity of rein action required.
