I love this bike too. 50-51cm is different on every bike. My 46cm Surly is actually bigger (standover and top tube) than my 53cm Burly was. I couldn't find the geometry on a Buenos Aires, but here is a Lemond triophe geometry that may help. Bike4ever told me that the top tube was the same. (You can't get to the Lemond website) I'm 5'4" and this geometry looks perfect for me. You can ask her if the rest of the geometry lines up. She manages a bike shop, so she will know and will give you good information. Just think, campy components!
It would be great if you got it, because I keep looking at it and looking at it and looking at it...
