Abstract

A multiple-sprocket arrangement for mounting on a rear wheel axle arrangement of a bicycle is provided. The multiple-sprocket arrangement includes a sprocket assembly having a plurality of sprockets of different sizes, and/or different numbers of teeth, disposed along an axis of rotation, for example of the rear wheel axle arrangement. The sprocket assembly includes a torque transmitting section configured to transmit torque to a hub sleeve, the torque transmitting section disposed along a first length of the rotation axis, and at least two sprockets having a smaller inner diameter than an outer diameter of the hub sleeve, the at least two sprockets formed as a separate piece, or pieces, from other sprockets of the plurality of sprockets and positioned over a second length along the rotation axis, the second length distinct from, and disposed outboard of, the first length.
