People have done and still do that. We had a customer whose BB shell literally turned to powder due to extreme corrosion. Hopefully just via sweat and maybe drink mix but it is a tri bike so probably a bit of pee as well. However I don't hear of issues happening often with creaking though dissimilar materials aren't ideal.

I think the trick to everything is super high tolerances from frame manufacturers and also BB manufacturers as well as using thread together BBs. Or just don't use carbon. Steel is real, Ti is fly and Aluminum simply doesn't rhyme easily so let's eliminate that. Wood is good but unfortunately Renovo while super beautiful didn't have the business side down well from what I hear.

I have got to wonder thinking about this why Headsets are generally not problematic but bottom brackets are and why can't we do a headset on its side, basically?
