A bicycle wheel dropout assembly that includes a split component axle mount assembly. An inboard and an outboard component of the axle mount assembly cooperate with overlapping portions of a respective seat stay and chain stay and are rotatably engaged therewith. An axle passes between adjacent mount assemblies and is offset with respect to an axis of rotation of the respective mount assemblies. The axle mount assemblies secure the overlapping portions of the seat stay and the chain stay relative to one another and support the axle in a manner that is convenient for drive train maintenance and/or servicing.
