I am in the process acquiring new gravel bike and idea is assembly it around carbon frame from aliexpress.

Carbon frame bottom bracket T47

There is also older version of this frame but with press fir bottom bracket 386

From start I was thinking built it with Sensah groupset but two things I do not like: mechanical/hydraulic brake combo and most of the cranksets have aluminium spindle (which can and does brake).
So I opted to GRX400 version with crankset 46/30. Most expensive things are shifters. Hydraulic shifters from Sensah compatible with GRX (PRO HRD) are in similar price range.

Related with wheels I do not want anything fancy and pricy, so something like this:

I am also open for 1x11 or 1x12 combination but this do not look make big difference in weight/cost benefit.
Created sheet with some cost, weight calculations:

Would personally go for a push fit bb to avoid bonding issues with the t47 shell.

vknez:
What kind of bonding issues you think?

Bonding issues are a lot more rare than press fit issues.

I'll prefer threaded BB over PF, be it good ol' BSA or T47. I'm seeing a lot of Chiner frames are BSA/T47 now a days (over BB386) from just a year ago and I'm glad.
