Produced 2007~2013. The interesting line is "may corrode and
fail". Not the usual, "may crack and fail". CPSC reports
exactly one incident with injury.


Profile is one of the best stems I've used. Corrode and fail?


In that this particular model is carbon-wrapped aluminum, I
suppose that's a galvanic corrosion effect.

Maybe. But galvanic between what and what? Surely carbon is inert. I think it more likely that there was inadequate adhesion, air got in, a further layer of aluminum's self-defense layer was formed, furthering delimitation, and presto, a failure. One. One failure doesn't get my heart rate up much.
