CAAD 12 - 55.1/38.7 - 56.7/39.3
So not only does a CAAD 12 in size 56 not fit like CAAD 10 size 54, it actually fits a little larger than a CAAD 10 56. You are way off in claiming that CAAD 12 56 = CAAD 10 54.
What measurement are you calling 54/56? The size sticker on my bike said 56, but it had a 57.5 effective top tube. There is an extra row on the chart called measured size (referring to the size sticker on the bike) that doesn't read inline with the rest of the measurements for a size. Cannondale geometry charts for caad8/10 and the last version of the evo are unnecessarily hard to read for that reason, IMO.
