I am 5' 9 1/2" inches tall, 32 inseam. Been looking at road bikes, size calculators say 55cm frame. I have tested some Cannondales at the LBS, 56 seemed decent, but the 54 did too.

I am real tempted by a used Allez Comp, but it's a 56. It's not nearby, so test rides are out. Some here say smaller is better, others the reverse. Would being slightly too big be a mistake?

Need some opinions before pulling the trigger.
