That makes sense.
So in some of those instances I suppose the frame quality could be very close to the "good" brands, it's just more of an ethics issue as to why you would chose to not deal with those companies? (Totally agree in that case.)
Also, I've seen some companies just clearly settle for inexepensive materials, like all of the broken forks coming from a company that makes aero frames.
Thanks for the insight on the bike industry, I think it's pretty interesting.
