However if this is a different style bike for different type of riding... IE, leisure vs high effort fitness, then I'd dispute any thought that saddle setback to the BB needs to be the same.
It was originally a forme victeur either 56cm, 57, or a 58 frame I cant remember... now I own a planet X RT80, 60cm frame....
It was 9cm behind the BB on the forme victeur 81.5 cm saddle height, 1.5mm of spacers, and 140 stem, it had the additional 1.5-2m spacer underneath the mainspacers...
