And guys...when I was young and a student of cycling and trying to figure out my best fit, I wrote to Sheldon Brown for advice and asked about riding a 60cm bike with shortish stem and he was gracious enough to write me back in his profound style and say...
anything in the 80-120mm range is perfectly acceptable on a large or extra large bike. He went on to say that humans are extremely adaptive creatures and any effect of shortening the 'tiller' would be quickly adjusted to in terms of handling. He went on to talk about owning a wide variety of bicycles from all over the world in all shapes and sizes including a 60cm bike with short stem. He was just over 6' tall like me and one of the reasons I sought the great man's advice. He used the analogy of owning a tandem and how it handled versus his shortish wheelbase racing bikes...the miles melt away any significant difference in handling.
