1. A rear sprocket configured to be mounted to a rear hub assembly for a human-powered vehicle, the rear sprocket having a rotational center axis to define an axial direction, a radial direction and a circumferential direction, the rear sprocket comprising:
a sprocket body;
a plurality of sprocket teeth extending radially outwardly from the sprocket body in the radial direction, the plurality of sprocket teeth defining a plurality of tooth bottom center points spaced apart from each other in the circumferential direction, each of the plurality of sprocket teeth having a tooth outline extending from corresponding one of the plurality of tooth bottom center points to a neighboring tooth bottom center point among the plurality of tooth bottom center points in the circumferential direction;
a plurality of spline teeth configured to transmit a driving torque to a neighboring sprocket adjacent to the rear sprocket without another sprocket between the rear sprocket and the neighboring sprocket in the axial direction, each of the plurality of spline teeth having a spline crest;
a maximum spline distance being defined from the rotational center axis to the spline crest;
a radial tooth-bottom distance being defined from the rotational center axis to one of the plurality of tooth bottom center points;
the maximum spline distance being larger than the radial tooth-bottom distance; and
the spline crest of each of the plurality of spline teeth being positioned radially inwardly from the tooth outline of each of the plurality of sprocket teeth in the radial direction.
