So, just to close the topic.

I have done a BG Fit Geometry (my height is 182 cm and other sizing are mentioned in my previous post) and they said the Emonda 58 is perfect fit for me.
I am in between sizes 56 and 58.

The 58 is perfect, the handlebars are in lowest position, seat is almost as low as it can be.
Of course overall the bike is much taller and bigger than 56.

I could get size 56, but I would need longer stem, so... it all depends right.
