Try the bike fit calculator on competitivecyclist.com. It's design to help get the right size mail order frame. They sell Titus bikes.

I did it and got these results:

The Competitive Fit (cm)
-------------------------------------------
Seat tube range c-c: 52.6 - 53.1
Seat tube range c-t: 54.3 - 54.8
Top tube length: 53.9 - 54.3
Stem Length: 10.7 - 11.3
BB-Saddle Position: 76.0 - 78.0
Saddle-Handlebar: 51.0 - 51.6
Saddle Setback: 3.2 - 3.6


The Eddy Fit (cm)
-------------------------------------------
Seat tube range c-c: 53.8 - 54.3
Seat tube range c-t: 55.5 - 56.0
Top tube length: 53.9 - 54.3
Stem Length: 9.6 - 10.2
BB-Saddle Position: 75.2 - 77.2
Saddle-Handlebar: 51.8 - 52.4
Saddle Setback: 4.4 - 4.8


The French Fit (cm)
-------------------------------------------
Seat tube range c-c: 55.5 - 56.0
Seat tube range c-t: 57.2 - 57.7
Top tube length: 55.1 - 55.5
Stem Length: 9.8 - 10.4
BB-Saddle Position: 73.5 - 75.5
Saddle-Handlebar: 53.5 - 54.1
Saddle Setback: 3.9 - 4.3


Seem pretty dead on for top tube, stem recommendations, i.e., cockpit length.

But saddle heights are pretty off from my Serrotta fit. I use my saddle at 72.5, and set back 6cm. They recommend quite different. More higher and forward.
