Re: True CX frame (not gravel) I just ordered the tantan gr045! It has the exact same geo as the new Blue norcross. I believe tantan is the same mfg blue uses for their production bikes.

This is an interesting cross bike with long reach and 70 hta and longer front center than most cx bikes. I think its a great mix modern and classic cx geo.

Ordered from tantan's alibaba store. Will report back when I receive the frame.

Re: True CX frame (not gravel) I will post some pictures later but I have been meaning to share my experience with my cx build. 

Cyclocross is my primary discipline, and for this year I wanted a pit bike. I too wanted the true CX geometry with short wheelbase and high bottom bracket.  I landed on the GR029/FE-806/CX028  frame.  I put on SRAM force because that is what I like and I race single speed with the zip tied shifter.  I purchased through ebay store https://www.ebay.com/usr/yxbikes.  It included headset and thru axles (although the fork doesn't have a threaded insert, so it uses a quick release style thru axle), which added a level of simplicity.  It came with the flyxii top cap.   The crown race was a pretty snug fit, and required a pvc pipe to push it into place (https://nuxx.net/blog/2014/02/09/pvc-1-5-crown-race-setter/). 

The geometry is a bit funky.  I really wanted to get the stack down to a certain size.  This frame has a high stack and short reach.  So a compromise was required to get  the stack where I wanted.  I sized down, thinking I could run a bit longer stem.   This worked, but I will say, it puts your pressure vector on the front tire in a less desirable angle while cornering off camber.  I have since put back on  a shorter stem.

The build went very smoothly as it uses those clip in cable stops.  BB shell threads don't look pretty but they were fine.   I paired this with a set of 40mm superteams with onirii rotors (CD-02), which aren't great and have a slight creak to them, but serve the purpose just fine.  Other items include, Ryet 3D saddle, Uno 100mm stem, RXL SL 38mm, Elita One 27.2x350mm seatpost, and Bolany 11-36 cassette.  Basically a full chiner build with Sram Force.   

Total Weight came in with pedals and bottle cages just under 18 lbs.   

When the season rolled around, I raced it instead of my A bike, and I love it.   The bike rips corners and having a true CX geometry and sizing down a bit has worked really well for me.  I'd highly recommend this frame if you are racing CX but just be aware of the stack/reach combo.  I much prefer it over longer gravely type frames being used in cx.
