I'm pretty sure of the direction I want to go in, but figured it might be useful for other people looking at this particular model. The 2018 allez went more for an endurance style, shorter reach and higher stack, for example. My current road bike, a mid 90's raleigh, is a 56cm with a reach measurement of 39.5-40ish and a stack of 55. I had a fitting last summer and the fitter put my 120cm stem at +17, as I ideally fit on something with higher stack.

As for the Allez, the 54cm model has a reach of 380mm and stack of 570mm, whereas the 56cm model has 385mm reach and stack of 596mm. While I think I generally fit more into a 56, I'm feeling like the 54 may be better for me, as I do some racing so I don't want something too relaxed, and the 56 would seem to have me too upright. I used the bikegeo calculator the best I could (nice tool BTW, thanks for sharing here!) and the fit between my current road bike and the 54cm Allez appear to be pretty similar where I could get the stack to where I want without a comically steep stem (there's also the weight and better road feel associated with the Allez in comparison to my existing bike, which is why I'm even looking to begin with).

To add on, I have a 56cm cross bike that has a stack of 583 and reach of 380 and it's comfortable for me, but on the verge of being too endurance oriented, although it's great for my CX riding. Anyhow, I know people always have thoughts so feel free to weigh in!
