The Wall Street Journal featured a interesting article recently: "The Rise Of The Designer Bike"-http://online.wsj.com/article/SB10001424052748704517404576222540051051416.html?KEYWORDS=bicycles
Plus earlier interest in the same (or similar) topic here on Bike Forums: http://www.bikeforums.net/showthread.php/348183-WSJ-article-on-custom-bikes-for-the-masses?highlight=Designer+Bikes+WSJ on an earlier discussion on custom bikes and the original article, "Custom Bikes for the Masses ": http://online.wsj.com/article/SB119092693639341667.html
Now for the clincher. As a body of serious cyclists that use bikes for most if not all, of your transportation needs, is your bike(s) a result of intentional customization (like mine are), or just-off-the-shelf as is clones of everyone else'. ? Would you have it any other way?
