Geometry-wise, it's definitely on the Endurance end. That said, definitely test ride it. I rented a Roubaix Comp Di2 back in 2019, and it wasn't really the bike for me - ambivalent about the disc brakes, not used to the Di2, but really, really, disliked bobbing up and down on the suspension stem. I'm sure if I had more than a day with it, I would've been able to adjust my pedal stroke to be more compatible, but not so much with one 40 miler.
But if the bike shop says its available, go test ride it and let us know what you think!
