I agree with [MENTION=1534]jitteringjr[/MENTION] that even if you don't buy local, test-ride local. Try a bunch of styles of bike. Go online and download the geometry charts and compare numbers.

You don't really have to know what everything means---if you tried a bike with certain dimensions, another bike with similar dimensions should at least Fit the same. All bikes might feel different because of saddles, handlebar shapes, and wheels and tires ... but all that is cheap to change ... or easy to change.

Also ... almost any bike that is generally the right size will feel good for the first 20 minutes.

As jitteringjr notes, the Emonda is racy geometry ... you will be bent over and stretched out. Some people love this position and can ride comfortable for hours. Some (possibly more) people prefer to sit a little more upright.

Most frames can be adjusted via different stems, saddles, bars ... but why start with something you don't want and make what you want?

Most road bikes are split between "Race" geometry and "Endurance" geometry nowadays (Scan the list of threads for hours of pointless argument over the "true" meaning of these terms.) An Emonda is racy, a Domane is Endurance. A CAAD 12 is racy, Synapse is Endurance. A Giant TCR is racy, a Defy is Endurance.

Try the two types and see. On longer rides where sightseeing is involved, (and old shoulders and necks and lower backs) a more upright posture might help.

Also, the accepted wisdom nowadays is that 28-mm tires are about the sweet spot for speed and comfort. Some of the racier bikes might only fit 25s.

Also ... do you two mostly just want to ride, or do you want to ride and stop to share a snack, drink some wine, take some photos? Think how you might want to carry anything you might want to bring.
