For Sale: Colnago C50 Carbon Dura Ace 7800 - Road Bike

Very nice set up.
Is the frame sloping or traditional geometry?
Trying to figure out colnago sizing I normally ride equivalent of 54cm c-c.

Hi!
The bike is light sloping.

I have a feeling it's going to be slightly too big. When you have chance please could you let me know standover height? Floor to top of top tube. This will allow me to compare to my current ride.
Thanks for your help.

The standover height is 81cm near the head tube and 74cm near the seat tube, from floor to the center of the top tube. It's sloping.
