I have to admit that all this nomenclature business is foreign to me. Or possibly I just don't get it. IMO a good endurance bike is one which gets you from A to B quickly and comfortably, considering that A and B are quite far apart. Thus a good endurance bike would be about the same a good rando bike Randonneurs I've ridden with usually ride carbon bikes because of minimal vibration, low weight, and good power transfer.

I like a fit which has my elbows in front of my knees when I'm low and my upper arms acting as a strut, 90° to my torso. That way I'm not cramped, my back is straight, the miles go by quickly, and I'm not tired at the end of the ride. Oddly enough many race bikes make good endurance bikes as long as they go where they're pointed, are stable, and corner well.
