Abstract
A bicycle rear sprocket comprises a sprocket body, a plurality of sprocket teeth, an opening, and a torque-transmitting structure. The plurality of sprocket teeth extends radially outwardly from the sprocket body with respect to a rotational center axis of the bicycle rear sprocket. The opening has a minimum diameter that is smaller than a minimum outer diameter of a sprocket support body of a bicycle rear hub assembly. The torque-transmitting structure includes at least ten torque-transmitting teeth configured to directly or indirectly transmit a pedaling torque to the sprocket support body of the bicycle rear hub assembly.
