The only problem I have with the geometry of the steamroller is that the top tube is too long. If I ride the 56 I have to put the seat way up and farther away from the bars. If I ride the 59 the bars are just too far away to start with. Maybe I'm just an odd body type, but I'm 6'1'' and my ideal frame would be a 58x56 with fairly tight (track) geomerty. I also like to have the bars several inches below the seat so maybe I'm not the ideal model for a city rider. I've had a hard time finding bikes with this kind of geometry, and the more relaxed bikes just exacorbate the problem.
on a side note, a flat top tobe is MANDATORY and I'd even love to see a production bike with a slight drop toward the bars like a throwback to the old funny bikes. Something small, like a cm or two that would just be noticeable but easily corrected by raising the stem if you don't like it.
But like I said, I'm not a standard city rider. I only ride my bike 10-12 miles at a time and I have to admit its not the most comfortable set-up.
