Kobe 

I can find a quality bike in 60-63cm's all day long. That seems to be the top limit of most top of the line bike lines. They are tall but not freakishly tall like most riders 6'3" and up prefer. I think quality bikes in 64cm and up are just very rare.

Thanks @mtnbke for the praise on the Serotta. I guess I will need to watch my back. It was on eBay a few years ago and I got it for the opening bid, I am glad you did not see it. It's a little odd with the baseball bat tubing (nice article by Zinn btw, I never saw that) and long neck on the headtube, but it all works to be a great ride. I don't know if it was custom or not, this one http://cnj.craigslist.org/bik/5153174900.html is for sale by me. It is a lot more than I paid for mine but looks to be the same size. Let me know and I can facilitate for you.
