All my bikes are "antiques," so I really am not all that familiar with the new headsets... can someone clue me in? I understand that the threadless headsets are not height adjustable... so how does one set up the bike to fit the rider?

BTW to merlin... I still love my Columbus SL frame with downtube friction shifters and Gali gruppo... the weight of this old bike is amazingly close to that of several CF production bikes that I have hefted (what's a few ounces between friends, eh?)
