with this "S5" seat tube style, real world STA is maybe about 1-2° steeper then geo chart would suggest, depending on size and seat height.
So I would say even thou STA looks slack compare to normal bikes in reality STA would be much steeper than standard.
I would say this ICAN, XMCS VRT and light carbon LCR020 will have STA much steaper that geo chart would suggest.
I just tried to put geo reference picture to Fusion 360 and tried to align it. This is real STA that came out compare to geo chart in size M.
If someone have experience with this please pitch in If Iam wrong about this, I have never own this kind of geo on a bike, Iam just coming from my basic geometry knowledge

.
So every other bike that has two geo chart seat tube lines and seat tube does not come directly from bb center will be like this, STA much steeper than geo chart. Just another thing to be aware of when choosing a bike
