Want to try this though http://www.jensonusa.com/Azonic-Hammer-Stem
interesting stem, and it looks like it's being cleared out. bad timing? it seems to me this kind of stem may be what is needed for some of these new bikes. i found it quite interesting that a Mondraker Foxy was recently tested, and by guys 6'5" no less. they said the xl (recommended by the company) was so extremely long that they didn't like it at all.
Kever are you on a size xl bike? 480mm reach sounds like it. how tall are you?
