I'm 6'2" and ordered a 56. Initially went with the 59, but switched it a couple days ago to the 56. I ride a 59 pista right now and feel way too stretched out and unstable all around on it. It would have been nice if the IRO sizes were true to most other frame sizes, but for $150 I guess a little guessing can't hurt.

I'm sure someone out there will order a 59 and want a 56 when it's all said and done. If that's the case, I'll have someone to trade with...lol.
