I know plenty about quality, I spent $1500 on my bike, just not about quality brake levers. I probably know a lot more about quality then you, not just from a bike standpoint. I spent my childhood around car shows, where nothing but perfection suffices. I have studied sound and speaker development. I can tell you all about what makes a $27,000 set of speakers better than your 5.1 sony surround sound.
But so what I understand thus far is you pay and extra $80 so the hinge doesn't develop play?
