Curb bits vary widely according to shank and mouthpiece design, but there are two main categories and which pertain to the two types of horse riding: western riding, which uses looser reins controlled at the neck with a single hand, and English riding, which uses both hands to control the reins at the mouth of the horse.
bits usually have gentle ports (the upwardly curved center of the mouthpiece). A popular type of western curb bit is the curb bit specially designed with shanks that can hinge 90 degrees to help the horse graze.
English curb bits usually have shorter shanks than Western curb bits. A common type of English curb bit is the Weymouth, which has straight shanks and a low port, and the Liverpool bit, which has several rein-attachment slots that provide a choice of leverage power and severity.
