About 6 foot 4-5ish, smallest frames I can comfortably ride are 58s, and my daily is a 60cm Cannondale CAAD. I reckon this would fit me, but it's definitely not going to be at the small end of the scale for me, and I quite like bikes to be as small as I can get away with for practical reasons!
@Slappingpythagoras out of curiosity how tall are you?
