Too little info to make a realistic projection on fit. Roadie, city bike, mtb? Preferred position on bike = upright or aero?

I'm 6'1" and ride road bikes with 57cm Effective Top Tube, but they need a 13cm stem to feel right. If your 'wingspan' is greater than your height it might feel cramped or result in an upright riding position. You clearly won't be able to stretch out and get aero without a long stem.

Even when jonesing over a particular bike, it will only squash your obsession with a bad fit. A small fit, depending on the geometry of HTA and front-center, might be twitchy in handling.
