Is it really that hard for roadies to wrap their heads around a slightly misaligned derailleur, or are they just so accustomed to having every aspect of their bike meticulously dialed that they cant handle a bit of real-world variability? Its not like a misaligned derailleur is going to cause the world to end, yet you see riders freaking out over a few millimeters of deviation from perfect alignment. Whats behind this obsession with absolute precision - are they really getting better performance out of their bikes, or is it just a matter of aesthetics? Do the benefits of perfect derailleur alignment really outweigh the drawbacks of being unable to adapt to less-than-ideal conditions?
