SRAM developed the AXS platform to provide its customers with more options when choosing a groupset for their bikes. To run a SRAM 12 speed eTap AXS groupset a new freehub body is required, however.
The new XDR freehub body is based on SRAM’s existing XD freehub body technology but features a wider interface. It is intended for use on road and gravel bikes, while the XD freehub body will remain the main option for the use on mountain bikes.
Due to the specific build of its R series and O2 hubs, Scope has developed two XDR freehub bodies. Both feature a 1.85mm wider interface compared to the existing two XD models and come with a spacer ring to allow for the mounting of both SRAM 12 speed XDR as well as 11 speed XD and 12 speed XD cassettes. The R series XDR freehub body features a different engagement system than the O2 XDR freehub body, which are not interchangeable.
The Scope XDR freehub bodies will be available from the end of March for €69.
