An assembly comprising a driver for transferring torque from a set of sprockets to a wheel of a bicycle, the driver having a rotation axis and comprising a coupling profile for coupling the set of sprockets thereto, wherein the coupling profile includes a first adapter support surface configured for supporting a first adapter in a radial direction and a second adapter support surface configured for supporting a second adapter in, e.g. only, a radial direction,
- wherein the first adapter support surface is at a smaller radius from the rotation axis than the second adapter support surface,
- wherein the assembly in a first configuration comprises the first adapter supported by the first adapter support surface and is configured for supporting a first set of sprockets, and wherein the assembly in a second configuration comprises the second adapter supported by the second adapter support surface and is configured for supporting a second set of sprockets different from the first set of sprockets.
