every time I see a DIY singlespeed or fixie build up where the person chose the no-derailers route for supposed 'simplicity'
they inevitably have horrible chainline problems and give me a blank look when I explain to them that they need a different crankset/bottom bracket to fix it....
which then turns into a shocked/angry look when I explain how much the parts and labor will cost....
