2 cm going from 72 STA to 73.5 STA.

1.3 cm for 72.5 STA to 73.5 STA, right?

Thanks that really helps me figure out the math.

That means I can probably use a 110 mm stem with the same 57cm top tube if all I do is change the STA 1.5 degrees. (assuming I keep the same reach handlebars).

Or I can use a 100mm stem with a 58cm top tube and 73.5 STA.

I just like it that way.
