Summary: I know they only sell it as a one piece item and it is not recommended to repair After a brief inspection it was agreed that riding home was no problem 80km Time for some disassembly In the picture you can see the markings what the sprocket made Axle is in good shape bearings seemed ok too The LH side nut was loose and only the securing clip was holding it in place
