Bogey: seat tube angle is meaningless when descending, unless you're in your
seat, which you shouldn't be 😉
We'll have to measure ours but I do not think your TB can possibly have an
actual STA of 73 or 74 - it'll be less by several degrees at least. And that
means that the more post you like to show, the further in the back seat you'll
be when pedaling. An effective STA of 73-4 IS perfect for most people, but
many modern bikes have effective STAs in that range but an actual STA in the
high 60s, and that's problematic for certain body types.
