Here is their fit kit page. Surprised they recommended a 140mm, but 150mm is the biggest size so I dont really know. According to their fit sizer, you would need a 160cm (140cm +2cm for MTB position) which doesnt exist. Maybe try re-measuring with some cardboard to see if you can replicate the results you got in the shop? On the other hand, if its now comfortable, I guess all this measuring and conjecture doesnt really matter :)
Maybe because I was so close to 140 they rounded down?
