Drive system comprising a drive shaft and a chainring

Abstract

A drive system comprising a drive shaft (21) and a chainring (1), wherein the drive shaft (21) has a splined interface (22) for attaching the chainring (1) in a rotationally fixed manner. The drive system has an annular adapter (2) having a radially inner surface with an interface (20) engaging the splined interface (22) of the drive shaft (21) and a radially outer region with at least one first connecting element, wherein the chainring (1) has at least one second connecting element configured to engage the first connecting element, wherein the drive system comprises a first annular adapter (2) with a first axial extension defining a first axial distance between the interface (20) and the first connecting element and a second annular adapter with a second axial extension defining a second axial distance between the interface (20) and the first connecting element.
