So an additional question if anyone is still looking. As I said earlier, the bike I'm considering is 61cm. The bike I currently ride comfortably is an old steel 62cm with plenty of head tube.

I understand the geometries are drastically different. Bikeshop guy asked for my height, cycling inseam, and torso lengths.

They are:
height: 75"
cycling inseam: 38"
torso: 24"

Anyone want to provide a general opinion on sizing from this info? As I understand there are a couple of these bikes left on sale in different sizes, but is the 61cm gonna fit the bill?
