[Closed] Ridley cross bike sizing

Has anyone any experience of Ridley cross sizing?

I know they size from c-c on the seat tube so a 52 is actually a 56.

I currently ride a 54 crosslight with quite a bit of seat post showing

and a I ride a 56 road bike with this much post

A friend of mine had a bike fit done by oli beckingsale recently and he disagreed you should size down for cross it should be the same sort of set up as your road bike.

(I'm 5'9" with a 32 inseam)

just wondered if anyone has ridden the x fire/x night
