Jesus...
veganbikes I have a bike with a weak derailleur hanger that comes out of alignment just from normal riding. I've aligned it with a tool, and often align it by hand; I'm sure I've adjusted it 10 times over the years. That's not my point, though, my point is that I can make a video of me bending the derailleur hanger by hand (just by pulling on the derailleur) if it'll get you to realize you don't know as much as you think you know.
