bicycle component tolerances weren't the best with many manufacturers
And I'm sure that many were assembled with component "sweet spots" factored in for best fit-up. That and maybe "tweaked" just a little to conform to fit.
Gives one a whole new "heads up" when swapping in donor parts too, huh?
I may be over emphasizing the component relationships, but I've been trained on everything from Nuc Submarines to (well) BIKES!
