A bicycle sprocket comprises a sprocket body, a plurality of sprocket teeth, and a torque transmitting profile. The sprocket body has an outer periphery and an inner periphery positioned radially inwardly from the outer periphery with respect to a rotational center axis of the bicycle sprocket. The plurality of sprocket teeth is disposed on the outer periphery of the sprocket body. The torque transmitting profile is positioned around the inner periphery of the sprocket body. The torque transmitting profile includes at least ten internal spline teeth. The at least ten internal spline-teeth include at least one first internal spline-tooth, at least one second internal spline-tooth and at least one third internal spline-tooth. The at least one internal first spline-tooth, the at least one second internal spline-tooth and the at least one third internal spline-tooth are different in shape from each other.
