Apologies for asking this, but lack of mechanical knowledge.
Noticed today while checking over the bike for loose fasteners that one of the rear sprocket nuts is loose.
Thought it would just be a nut to tighten but there's what seems to be a central Allen key type pin that I presume you have to lock in place while tightening the nut.? Any advice appreciated. Thanks
