Bit′ting-rig′ging.
(Saddlery.) A bridle, surcingle, back-strap, and crupper. The bridle has a gag-rein and side-reins, the latter buckling to the surcingle. The rigging is placed on young horses to give them a good carriage, but must be released occasionally, as the bent position of the neck and elevation of the head is unnatural, and takes time to acquire.
