ABSTRACT:
A sprocket support for a bicycle includes a first outer peripheral surface portion and a second outer peripheral surface portion. The first outer peripheral surface portion is adapted to support an inner peripheral surface of a first sprocket for rotation around an axis, wherein the first outer peripheral surface portion defines at least one radially inwardly extending spline and at least one radially outwardly extending spline. The at least one radially inwardly extending spline has a radially inner surface with a first radially inner distance from the axis, and the at least one radially outwardly extending spline has a radially outer surface with a first radially outer distance from the axis. The second outer peripheral surface portion is adapted to support an inner peripheral surface of a second sprocket for rotation around the axis, wherein the second outer peripheral surface portion defines at least one radially inwardly extending spline and at least one radially outwardly extending spline. The at least one radially inwardly extending spline has a radially inner surface with a second radially inner distance from the axis, and the at least one radially outwardly extending spline has a radially outer surface with a second radially outer distance from the axis. The first radially outer distance is greater than the second radially inner distance and is smaller than the second radially outer distance.
