when I went to one of our lbs, the salesperson just sized me up to be a 56cm. I test rode a white CAAD 10 that they had displayed on a top rack. The only thing that needed adjustment was the seat height and tire pressures. I really liked the bike and I had my heart set on buying it. I found a better deal of a new black CAAD 10 5 online that is completely stock, so I made the purchase instead of buying from lbs. I know people should support their lbs, but with the savings I made, I could buy another quality wheelset. I say, to the op, to test ride both 54cm and 56cm and go with what feels best. I come from previous bicycling background of sorts, so it was easy for me to know what feels right.

^ I'm probably around 5' 10",..... if I have shoes on, maybe 5' 11". Since I wear shoes while riding, it makes a slight difference in seat height. The salesperson at the time I test rode a white CAAD 10 at a lbs, offered to put me on a trainer for a more specific fit, but I just agreed with him on his suggestion that a 56cm should be the right fit. Before entering the shop, I searched online on pointers on how to get the right sized road bike, and pretty much a size 56cm is the correct one for my height. Either going with a 54cm or a 56cm, both can be tweaked for a better fit by replacing the stem, getting a zero offset seatpost, and selecting the crank arm length.
