V-ish shaped rim profiles are actually back in vogue with tire widths over 28mm. Look at rim profiles for industry leaders like HED vanquish, Enve SES 4.5, Roval CLX, Zipp 303 and 404 (after MY2022). At least for rear wheels, all these rims have v-ish profiles. HED and Zipp use v-ish profiles front and rear. I think the idea is that with wider rims and hookless beads, recapturing air trailing off the tire is less of a concern because it stays attached across a wider range of conditions than before.

Actual market leaders (i.e. CRW Works, Roval Rapide CLX II) don't use v-shape profiles. Zipps are trash tier wheels in general.

It's certainly a stunning bike, but it is more akin to an Aethos/SL6. I just have a soft spot for the aerolight road bikes like the v4rs, the Xelius DRS and the Addict RC, but I haven't found something visually appealing in the chinese market which is not a full endurance (SLC3, Afield) or a full aero race bike with weird quirks.

I'll swing other way – what about Velobuild VBR177? It's light, stiff and has similar tube profile to Addict. The only downside is the BB86 bottom bracket

They either have less rolling resistance or more comfort, not both at the same time.

And in my experience, albeit clouded by frame material etc, the road comfort going from even a 28c road bike to a 42c gravel bike is marginal. We're still talking about zero suspension frames and bumps being handled by a few mm of tire. Narrower tires are lighter and more aero. I think for decent roads 28c is the sweet spot. 32c makes sense more for flat insurance than comfort IMO. I have 28c and 32c on some of my bikes and don't feel a huge comfort difference.

Weight difference between 28mm tyres and 32mm tyres are literally 100% irrelevant.

So when ordering you have selection of 5 sizes ranging from 460 to 550.

Geometry chart provides 6 sizes ranging from XS to XXL.

The website is completely useless.

Riro / racework carbon crank:
some people will warn you of the aluminum axle, but the 24mm diameter will leave more bearing size for the pressfit bottom bracket
170mm crank length, not good enough for Pogi wannabes
Magene P505-S1103 powermeter in 3-bolt
Pass Quest chainrings, available in SRAM gearing 48/35 and for flattop chains

Would you rather change your BB bearings more often or have spindle break mid-ride?

Looks like a really bad mash-up between the new Colnago and the Madone rear hole.
I kinda liked the previous Falath Evo, had they just reduced the distance between the wheels and the frame a bit more and gotten the weight down a bit it would have been a fine aero bike. Then again, Elves sales are imo mostly carried by their fancy paintjobs.

Let's not act like Colnago totally didn't rip the design off from 2 of their competitors.

Hmm, very Madone-esque looking frame. Is it just me or is the wheelbase really short?

Compared to what other shape tube ?

Peak Torque has done a video few years ago on compliance of carbon tubes, he also did a simulation of load bearing of few most popular seatpost shapes:
https://youtu.be/C8eg4O3OrvM?si=oRzFzLxhokAimy3J&t=831

27.2mm carbon seatpost had about the same seatpost as D shape post or minimized aero seatposts (he used Giant TCR's shape, but Tarmac, Specialissima and some other bikes have very similar shaped posts). Deep aero seatpost was the most stiff, but it also had the biggest surface area by far considering it had same wall thickness as other tubes (that might not always be the case, i.e. my Winnow aero bike's seatpost is thicker at the front and back, but sides are quite a bit thinner).

In the very same video he also brings up the point about chassis for cars and roll cages – round tubes are used for making them because round tubes are probably the best choice for handling complex loads
