But if you compare geometry of all 4 models, they are identical in every size. Now I know carbon layup and design can modify attributes, but I expected some geo differences. I even suspected an error in CC's web info, but Ridley's parent page has the same info.
Thoughts? And OP, no thread hijack intended. Feel free to give me a stern rebuke

You would that that the three parameters you reference would be somewhat competing. Endurance geo isn't particularly aero...nor maybe race stiffness....but I believe an endurance geo bike can be designed with these properties which is likely the case.
My Roubaix has race stiffness for example and endurance geo of course...and maybe 'loosely' construed as designed with an eye toward aerodynamics...but a slammed aero frame is gonna beat it in a wind tunnel of course. What you have likely is a bit of marketing going on.
