Well, I guess my question is more about the head tube angle. I'm not a framebuilder, so I'm wondering if a 5mm drop at the front end would change the head tube angle in a significant way. The bicycle isn't built yet, so it's not a matter of "ride it anyway." I simply don't want to spend the time and energy building something that won't be a decent ride.
With absolutely no knowledge on the subject, my gut tells me that I probably won't even be able to tell the difference. Having said that, I also know that sometimes even very slight changes to geometry can have a tremendous effect overall. I didn't consider the idea of adjusting the stack height to compensate (good idea).
Really, a 5mm drop at the front end might change the head tube angle, what, about .01%? Right? Who's gonna notice that?
