A bicycle sliding dropout comprises a slider, the slider comprising an axle receptacle. A body is configured for attachment to a bicycle frame. The body and the slider are configured for slidable engagement relative to one another when operatively associated so that the slider may slide first and second opposite directions relative to the body. The body and the slider further comprise cooperating structures selectively limiting the slidable movement of the slider in a first direction and cooperating structures selectively limiting the slidable movement of the slider in a second direction.
