Im 172cm tall. The manufacturer reccomend i take size S 48cm. Normally 53 to 55cm frame should fit me right? What's going on here

You ever use bikeinsights.com? You can compare frame geometries between the bike you’re interested in and a bike that fits you.
I think those labels are different to western sizing, so i guess their 48cm is equal to the usual 52cm
It’s a sloping frame so the traditional C-T measurement doesn’t really mean anything. Stack and reach are the figures you need and compare those to your old bike. Seems to be a racing geometry with low stack.
Try to book a fitting. I have 5 bikes and they are all different sizes. Really depends on the geometry of the bike and the riding position that feels most comfortable on that frame.
What they indicate as size here is seat tube length. Which is also what was typically indicated as size for vintage bikes – but in the past, seat post length and (effective) top tube length were very similar, and the latter one size is the more relevant and fitting size: with a sloped top tube (as here), seat post length gets shorter despite the geometry being the same.
So ideally: check for stack and reach, if you know your values.
second best: go for effective top tube length (which is always measured horizontally, never sloped with sloped top tube).
Here size 53.5 top tube is a size M-50.
