I'm sort of with Agave here. Most algorithmic fit calculators seem to fall apart at extreme heights or unusual body proportions. I'd really like to see what the Eddy fit would recommend if for Eddy's actual measurements.

You're in good company-- Eddie and Axel Merckx, Felice Gimondi, and Fausto Coppi were all tall racers with rangy builds. Though I wouldn't recommend using Coppi's fit as a model.

You might be able to get comfortable on a 60-62 cm stock frame that happens to have a short-ish top tube, with a slightly extended head tube to ameliorate the reach. Check out a Trek Madone, H2 fit, in 60 or 62, a Scott CR1 in 61, or a Bianchi Infinito or Sempre in 61.

Generally, taller guys can handle a little more saddle-to-handlebar drop than their shorter buddies, but you don't need to go super aggressive.

Whatever you end up with, anticipate swapping for a shorter stem.
