seeking aluminum braze-on downtube shifter bosses
If not the ones that go side by side, I would like even more a set that is aero style, that sits on top the downtube instead of flanking it.
Is this a thing?
I'm probably not using the right terminology when I say braze. Is aluminum brazed? It TIG welded the proper term?

I have a silly project.
