I was thinking of getting one of the Motobecane/Bikesdirect titanium frames. The only thing holding me back were some comments in a recent road forum thread. Someone said the frame has poor geometry at the highest sizes. The claim was that the seat tube angle was too steep, and that the steering would be twitchy as there isn't much trail. Some people also commented that Titanium isn't good for big guys as it tends to flex too much. Any big/tall clydes riding one of these bikes that can comment? I'm 6'5" and 190 lbs.
