I own a Specialized Diverge (Endurance), a Cannondale CAAD12 (normal race/climbing), and a Canyon Aeroad CF SLX 8.0.
I have to say, from left to ride, I have to bend lower and lower for the same position on the hood. With the Diverge and the CAAD12 actualy not THAT much difference. The Aeroad though... definitely gotta get lower :x
I am a small build for male, so I ride the smallest size from each company XD 48, and 2XS >_>
tbh, the CAAD12 is surprisingly compliant if you upgrade it with the Cannondale carbon flex post. It feels really good. However, the Aeroad actually have less buzz overall (but bumpier on the butt). I would not ever get an Endurance bike again tbh even if I wanted something more 'relaxing', I'd just get one of those normal 'race' geometry (non-Aero ones, Giant Propel, Aeroad, Specilaized Shiv), and upgrade it with more 'compliant' seat posts. I really dont' feel a difference between CAAD12 and Diverge <_<
