bike sounds right size for height. Is it a Synapse (or CAAD8), or a Supersix evo ?(CAAD10, CAAD12) fit? The latter has a shorter head tube and a longer top tube. Like someone else said, move things around. It's your bike, you can flip the stem, move the levers back on the bars, move the saddle forward, or back, or rotate it a bit, but try things a little at a time. There are fairly decent videos out there for setting your saddle height and position, but I think that bar position after that is just far too personal to be done watching a video.
