Al anodizing is harder and thus less flexible then the underlying Al rim. So it will generally crack before the base material does. But the qualifier is "before". In time the crack in the ano will be the stress riser for the base Al to start that crack at. Once a rim crack starts it's only time before that spoke hole won't support the nipple. Andy
