Abstract: A rear sprocket comprises a sprocket body, a plurality of sprocket teeth, a plurality of spline teeth, a maximum spline distance, and a radial tooth-bottom distance. Each of the plurality of spline teeth has a spline crest. The maximum spline distance is defined from the rotational center axis to the spline crest. The radial tooth-bottom distance is defined from a rotational center axis to one of plurality of tooth bottom center points. The maximum spline distance is larger than the radial tooth-bottom distance. The spline crest of each of the plurality of spline teeth is positioned radially inwardly from the tooth outline of each of the plurality of sprocket teeth in the radial direction.

Abstract: A bracket apparatus for mounting a derailleur to a frame of a human-powered vehicle comprises a bracket body and one of a restriction member and a restriction opening. The bracket body includes a frame attachment portion configured to be attached to the frame of the human-powered vehicle and a derailleur attachment portion to which the derailleur is to be attached. The restriction member is configured to be at least partly provided in the restriction opening to restrict a rotation of the bracket body relative to the frame of the human-powered vehicle in a bracket mounting state where the bracket apparatus is mounted to the frame of the human-powered vehicle.

Abstract: A rear sprocket assembly comprises a sprocket carrier, a first sprocket, and a second sprocket. The sprocket carrier includes at least one sprocket mounting portion having a first radial section and a second radial section. The first radial section has a first maximum axial length with respect to the axial direction. The second radial section has a second maximum axial length with respect to the axial direction. The second maximum axial length is larger than the first maximum axial length. At least one second mounted portion of the second sprocket is configured to axially contact the first radial section and the second radial section of the at least one sprocket mounting portion of the sprocket carrier with respect to the axial direction.
