Just a thought... do you need the aero bars? Are you doing triathlon? If not, then the bike might fit you ok to just ride with the drop bars. To get a good fit with bar extensions, many people need to go down a size with the top tube. For example, my road bike fits great, but it would be horrible for using clip-ons. I'd be so stretched out! It's worth considering at least if you can't return the bike. That said, I agree with several posters that this size bike is probably too big for many people of your height. Looking at the fit they've done on the bike, it definitely looks like you could go down at least a size. BUT you probably won't be able to get the bars so high relative to the saddle with a smaller bike (which will have a shorter head tube), if that position is what you are looking for. It looks like you've got the bars at max height on this bike.
