TanTan/SERAPH GR047 new gravel frame

As I make up my mind and wait for reply from Carbonda. I started digging around. After some poking, Lisa from TanTan told me that they have a new frame called GR047. The questions that I asked were, any lightweight frame that does not have PF BB and moderate geometry with internal cable routing.

The GR047 seems to have interesting top tube and angled seat post. My main draw, of course, like I asked is the T47 bottom bracket which I have not seen on many Chinese frames. The geometry puts it squarely in the territory of CRF696 and Velobuild GF-002, both of which I like.

The distinct advantage over GF-002 being the inclusion of T47 BB - though I have not seen evidences of VB's tolerances being sloppy so that point could be moot. 

I couldn't find the frame on either of the website but their YT channel seems to have listed some videos of it on 28th of last month.
One of my gripe is the flap that seems to hide the seat post tightening screw. I have something similar on my Giant Revolt and it NEVER stays in place. The second gripe is funny looking seatpost-chainstay connection. Also, the braze on FD hanger seems like it has scope for height adjustment :S

Thoughts and comments on the same?

P.S. The geometry diagram does not match with the pictures of actual frame but the numbers are correct per the sales rep.

And of course the color question is still open... What did Lisa tell you about the price and painting costs? 

$90 for single color, 100 for two and so on. You have to send them Pantone color codes. Shipping $150 to the USA. 

…and how much for the frame/frame-set?

It was $500 including handlebar (integrated) and everything else. I ultimately did not go for it though. Size L wasn't available back then and not a fan of integrated handlebar either. Much prefer something with distinct stem and handle. 

Worth mentioning. Same frame is now available at Velobuild christened as GF-003. The geometry, completed build pictures look exactly like Willier Jena.

I came across it by accident yesterday - however, Velobuild mentions the carbon fiber as T800, SPCycle and TanTan/Seraph mention as T1000...

Good catch.
I read somewhere that VB doesn't actually manufacture frames rather just resells them while SPCycle does manufacture - my recollection could be wrong though. In case its not wrong, I think the type of CF being different could just be a clerical mistake.
