A bicycle sprocket arrangement comprises an internal spline configured to be engaged with an external spline of a sprocket support body of a bicycle hub assembly. The internal spline includes a plurality of internal-spline driving surfaces configured to transmit a rotational driving force between the bicycle sprocket arrangement and the bicycle hub assembly in a circumferential direction. The plurality of internal-spline driving surfaces includes at least four first internal-spline driving surfaces and at least one second internal-spline driving surface. The at least four first internal-spline driving surfaces are respectively arranged on at least four of nine first internal-spline driving positions equally arranged in the circumferential direction about a rotational center axis at a first internal-spline pitch angle which is equal to 40 degrees. The at least one second internal-spline driving surface is offset from the nine first internal-spline driving positions in the circumferential direction about the rotational center axis.
