Tashi, yah, I saw too much of that stem
Just rolled steel, not even a piece of pipe and not terribly long either... Did you see how the rear bars attach to the front seat? No height adjustment possible! (except by pivotting) They could have made a little bolt-on bracket just as easy I would guess?
My Torpedo selector didn't want to stop in first, until I WD40'd it and flicked it obsessively for a while. The tiny spring that flips the little stopper tab in there is rather slenderous. And the whole gadget is rivetted together - like they thought we'd never want in there.
