When I left the cycling world back in the early 80s we pretty much had threaded head sets and quill stems. Now that I have returned, and am trying to catch on the years that I missed and the new trends and such.... I find that I am curious about threadless headsets. What exactly, for the everyday cyclist, is the advantage of threadless over threaded? Or is their one? Admittedly, they do look pretty cool in some respects. But is one better than the other?
