I assume that question was asked for the purpose of pointing out a mistake, not for the purpose of answering a question which had an obvious answer in the first place. For some reason, nobody points out other peoples' mistakes, but mine seem to be a popular target. Anyway... just saying "ALUMINUM, Chris" would be good enough. We're mostly adults here.

Those are the strongest wheels, but they are steel. As far as aluminum goes (which must have been the purpose of the question), I'm not sure. It seems as if they all bend pretty easily. I can say which ones are NOT strong:

later 900T 16"
940 model 20 spoke 15" (very bendy)
Draco (5spoke 740T type wheels) bend if you look at them wrong.
760 (later) 15" dished... very bendable also

Those I know from experience. The rest of them, who knows. I don't think there are any strong ones out there aside from perhaps some of the 15" 740 16v ones with the big center covers. Those look OK but I don't KNOW if they're good with respect to bending.

To answer the question, those are exactly the ones I mean. Without a doubt much more bend-resistant than the aluminum ones. But since the question was about aluminum wheels, I'll retract my first answer.

Happy memorial day.
