Alright, since we're getting into a goddamn snit on the internet (that's what it's for), and totally derailing the thread: I said "opposite of everything you've ever threaded in your life", not "opposite of everything on your bike". Ever open a bottle of soda? Do any basic carpentry? Open a jar of mayonnaise, peanut butter, et al? I guarantee even a professional left-pedal installer uses right-handed threads exponentially more than left-hand threads. They are uncommon. Off the top of my head, I really can't think of any place I've used them OTHER than on a bike, and how often do you muck with your left pedal and/or lockring?
