I have a 2002 Ultegra 9-speed triple with 52/39/30(?) chainrings. I swapped out the inner two chainrings twice and kept the original crank and 52-tooth ring. The 52t ring only gets used going downhill and weighing in at 134#, I don't put much pressure on it.
Are there ultegra quality replacements available, or do I need to update the crank+rings?
