Shorter chainstays and a slightly steeper seat tube would get me interested. This would probably reduce the top tube length by a bit as well.

Exactly.

73.2 deg of seat tube angle in size 540 ... the trend in both road and mtb is going in the 75-78 deg range now (and something like 70.5-71-71.5 deg in the steerer), so I would not even consider buying another of these 73-73.5 deg (SA) / 72  deg (HA) frames. It is just super obsolete in my opinion. Having a more upright seat tube brings your weight to the front to gain traction, improves efficiency and, in my case, reduces lower back pain (confirmed with a bikefit). In fact, this is the direction I went with my titanium frame, and I think the geo I designed for that bike is sublime.

Not that I'm in the market for a gravel frame as I just built one up, are you saying its too race oriented geometry wise? I've been on the hunt for a gravel race bike that clears 50s.

I just don't get this, honestly, but I acknowledge it is becoming super popular. 50mm tires is sluggish as hell. For bikepacking and doing lots of off-road it is a blessing because it just eats anything, absorbs anything. But if you want something road-oriented, aero maybe? 50mm tires just brights the opposite. For racing I would honestly go in the direction of CX frames/wheels ... something around 30-40mm tires, maybe more knobby if the terrain is very muddy/broken.

What I really want to see is one of these types of frames with bigger brake rotor options and a suspension-corrected fork/geometry that works well with 40-50mm travel. I need a very upright cockpit to prevent drop bars from destroying my already damaged spine, and would like something at the leading edge of current trail-capable gravel bikes without crossing over into an XC flat bar hardtail.

Why not something like the Lexon reverse and building a monstercross with it? Cheap as hell, can take up to a 40T chainring, 70.5 deg steerer (even more vertical if you take lets say a Rockshox SID, a Fox 32 and reduce the travel to 80mm, or a lauf trail racer ... also would bring the seat tube angle up). I have that frame (and I think it is excellent) and if it was not for the 3 gravel frames I already have (  ) I would go for a monstercross conversion. I think it is really asking for it

400mm reach with 570mm top tube in size 54, plus outdated seat tube inclination, 435mm long chai stay.

I am sorry but the design is a little Crazy. If they have put 75 deg in the back maybe they would bring the saddle closer, reduce top tube to something reasonable and paired with a short stem it could work. But this .... I don't see it

+1, there are no real endurance frames out there with a relaxed geometry (for size 54 something like ~375 reach and a ~600 stack) and big clearance. I would likely get one of those.

There are 10-51 casettes now (for both 12s and also 11s !!!) with the shimano distribution (51t jumps to 45t instead of 42t) but XD hub.

The two I have (on the full suspension and the gravel) work flawlessly with a GX AXS, but they are pricey unless you buy them on sales (they dropped to around 75 bucks in the 11/11).

Finished and tested

They look seriously awesome, but my worry is how they will look under sunlight. Garmin in this is excellent.

I don't know why people put the AliExpress links in a wrong way, it is not that difficult !
