Why do bike makers spec bikes with set back seat posts? Shouldn’t they just make the the seat angle slacker? That was the worse sentence ever on this forum. I will let it stand as is.
I understand using a setback seatpost during fitting but why spec it?
I’d say that the slacker the seat angle, the further rearward the rear wheel must be. Using a setback seat post is a workaround that gets your seat over the rear wheel, without pushing it too far back.
