The only questionable item are the spokes as I don't recognize the maker. Anyone know who they are?
"Nirosta" is not a brand of spokes, it is a German acronym for NIchtROstender STAhl, meaning "non-rusting steel"; a product of ThyssenKrupp AG, it is the material of which the crown of the Chrysler Building is constructed. One might infer that it is of reasonably good quality.
