I think I'm missing something about the assumptions posters above are making. Can't I take the measurements for the new frame given above and end up with the head tube positioned just about anywhere? I mean, I was thinking it could be a bit towards the gran fondo style frame, or a very aggressive geometry, depending on angles that are not given. I thought the only way to truly know would be comparing frame reach and frame stack. As I said, though, I'm likely missing some assumption that makes this all work out.

As for saddle relative to bottom bracket, I can see that being similar on the new bike with the adjustment of moving the saddle forward relative to seat post.
