It looks fairly simple and elegant (then again, so does the Cervelo P5 Disc), but it certainly is not the most adjustable bike as they like to put it. Also, to me, the lower seattube looks to be at point of breaking any moment, can't help with that feeling
For the price they're asking, I'd take the P5 Disc frameset, and build with the wheels of my choice - probably way cheaper than 12k EUR.
The climbing spin is a joke, especially, with that 1x (and who runs a 50T front ring on a TT machine?????). I've got an upcoming local TT, which starts (but does not finish) with a 900m 9% climb and with my pathetic power I'm thinking what to do with that hill and my 54T 1x setup, but this bike wouldn't save me from that problem anyway.
