Thank you for your feedback.
Just did a measurement on my inseam again.
Shucks, I think the Bike Shop told me wrongly.
I calculated and found an inseam of 75cm. (from feet to crotch).

The bike shop i'm getting the CR1 from has only the XS in stock, and they are pushing really hard to get it sold. The S size was the owners bike in which I tried on. Don't want to be buying the XS if it really does not fit properly.

Thank you.
