A binding mount for mounting a binding to a snowboard includes a lower portion, an upper portion and a lock. The lower portion is attached to the snowboard and has a protruding lip with at least two circumferential notches corresponding to at least two positions between which the binding mount is selectively rotatable. The upper portion has an upper surface adapted to receive a binding and a lower surface that receives the protruding lip. The upper portion has first and second pieces that are removably assembled together at a junction extending through an axis of rotation. The lock is coupled to the upper portion and is actuatable by the user to selectively lock the position of the upper portion relative to the lower portion by engagement with any of the notches in the lip.
