    Abstract: A bicycle rear sprocket assembly comprises a plurality of sprockets and a sprocket carrier. The sprocket carrier includes at least ten internal spline teeth and a circumferentially extending non-splined portion. The at least ten internal spline teeth extend in an axial direction with respect to a rotational center axis of the bicycle rear sprocket assembly. The at least ten internal spline teeth includes a plurality of internal-spline driving surfaces. The plurality of internal-spline driving surfaces each includes a radially outermost edge, a radially innermost edge, and a radial length. The total of the radial lengths ranges from 11 mm to 14 mm. The circumferentially extending non-splined portion is disposed to be adjacent to the at least ten internal spline teeth in the axial direction and recessed from the at least ten internal spline teeth in a radial direction with respect to the rotational center axis.

    Abstract: An electronic device includes a receiver, a computer memory device and a processor for calculating a human input force and/or a human input power that are inputted to a drive train of a human powered vehicle. The receiver receives first information with respect to torque applied to the drive train, and receives at least one of second information with respect to a gear engagement state and third information with respect to a crank rotational speed. The computer memory device has prestored correction factors with respect to the gear engagement state. The processor calculates the human input force based on the first information, the second information and at least one of the prestored correction factors, and/or calculates the human input power based on the first information, the second information, the third information, and at least one of the prestored correction factors.

    Abstract: A bicycle rear sprocket assembly comprises a plurality of sprockets and a sprocket carrier configured to support at least one of the plurality of sprockets. The sprocket carrier includes at least ten internal spline teeth and a circumferentially extending non-splined portion. The at least ten internal spline teeth are configured to engage with the sprocket support body of the bicycle rear hub assembly. The at least ten internal spline teeth extend in an axial direction with respect to a rotational center axis of the bicycle rear sprocket assembly and are spaced apart from each other in a circumferential direction with respect to the rotational center axis. The circumferentially extending non-splined portion is disposed to be adjacent to the at least ten internal spline teeth in the axial direction and recessed from the at least ten internal spline teeth in a radial direction with respect to the rotational center axis.
