!'m 6'2" and got a 58CM GT GTR (how's that for on point?) from eBay and it was too damn small. The fitter said so at the LBS and the responders said so in this forum after I posted pictures. Perfectly nice bike other than that, but that's obviously a deal killer.
Impossible! I had been fitted at my LBS prior to testing a 58CM Specialized Roubaix which fit perfectly. "Oh," my LBS tells me, "the Roubaix is special and it's probably the only 58CM that would fit you."
After a month I got a 58CM Roubaix. Ironically I got the bike on Thursday of a week between my first two centuries. I averaged 15.3 MPH on the GT and then a week later averaged 15.3 on the Roubaix after a single, short test ride the day before the century.
