I went to bed early last night. Still tired from the race
I'm 5'7". I think my inseam is significantly shorter than yours (I want to say 73 cm but I don't remember). I also rode a 52 Cannondale last (SystemSix) with a Thomson post low enough that I couldn't clamp it in a normal Park stand (not the new skinny clamp ones). In fact I could barely put a seat bag on (small one) above a blinkie. I also had a 13 cm stem, 73 deg (horizontal), no spacers at all.
Shot of me last summer on Cannondale. Yes, I raced heavy lol.
This is on the Tsunami.
Picture is a rough by Navone Studios.
I'd originally requested a 76 degree seat tube angle, 57 top tube (effective), "shortest possible head tube" which ends up being around 9-10 cm. The builder convinced me that 75.5 would be better, 56.5 TT, both based on his own personal experience. He said the head tube would be 9.5 cm, whatever they could get it down to.
With the top tube and seat tube angle changes, I got about 5-6 cm more length. Figure 4-5 cm because I went to a 12 cm stem (I'm already thinking of putting the 13 on later). I went from seeing my brake pad bolts in front of my stem (while on the drops) to seeing just the whole front hub.
I have more stuff in my blog, but I haven't posted anything with the bike as it is now - with rocket ship wheels. It's a really, really fast bike

Based on the weights here:

and the fact that I weighed my bike with its rocket ship wheels at 16.8 lbs, the bike is about 1.3 lbs heavier than the SystemSix with the DV46 tubulars. I put on a lighter saddle, much heavier fork, heavier front derailleur (not really that much heavier but technically true), and I think slightly lighter wheels. Everything else is the same, literally, since I pulled them off the Cannondale. Different headset but it's probably same weight.
I also lost weight. From the summer picture, about 25 lbs. From last year's Bethel Spring Series, 30 lbs. So do I notice the +1.3 lbs? Heh. Do I notice the -30 lbs? Heh.
Video of me in action, sort of, here:

At the start I rocket up the left side. Nervous I guess. At 3:20 or so my teammate and I are sitting together. At 5:20 I roll pass the camera guy. You can see how short I am on the bike

*edit* the seat tube, center of BB to top of top tube, is 40 cm. This mimics a size S Giant TCR aluminum (the carbon TCR I have is 44 c-t, the alum one 40). I like the 40 cm seat tube so requested it.
