I decided I might have a go at this fork oil change. I undid the top cap and found it was fully threaded into the depths of the housing
after that I shone the torch inside the housing and much to my surprise - no hex head or anything at all I could see to attach the 12mm hex shaft too
after that I decided not to go ahead and wait it out for answers. is it possible that threaded fork shaft bolt replaces the hex style which was originally unscrewed in earlier models to release the shaft?
