Round seat tube, dropped seatstays, disc brakes (SL6 style)- are there any left?

[Takiyaki]

I don't want to buy a fake SL6, and I don't want to deal with proprietary aero seat posts. What frames are out there? Seems like all the new stuff has done away with round seat tubes.

Velobuild 177

I mean, you could probably get a second hand sl6 2nd hand for the same price for less than the price of a new "copy".

I got a 2017 sl6 specialized frame (not s-works) rim for $1k

Or a TFSA / Delihea frame for 450 but they have a proprietary seatpost...

Yeah, Velobuild V177 is pretty much what you're looking for

OG-EVKIN does a round seat post:

Trifox x16 is a straight up Specialized (S-Works) SL6 clone. Same geometry and similar seatpost style (albeit proprietary).

Feedback seems to be good about Trifox, and this particular frame also allows for external cable routing. Almost bought one last year before getting my VB-177.

Those look like rebranded TFSA frames. Everything except for the seat clamp cover looks identical.

Is it just the style you're looking for or also the geometry?
In the first case Carbonda has the 1056 and 1136 frame.  But they are more relaxed than the sl7. If it is supposed to match also the geometry these two frames won't do the job

I thought the carbon guy from cam nichols video ripped apart trifox in terms of the quality?
Seem really heavy as well which you probably don't want for a "climbing" bike

IIRC, TFSA is the manufacturer of both Trifox and Delihea frames

So you can get it cheaper at the source

Should I just relax on the proprietary seatpost thing? My logic is they supposedly have less issues with fit, and are more comfortable. If neither is a big deal then I will just get the Elves Falath Pro I really want.

I have build up the TFSA frame last week and have yet to find a way to stop the seatpost from slipping (I have not tried a lot of methods though  ... So yes, it is a thing... It is possible you will have to find a workaround because just installing and torquing to the right torque is not enough...

[Takiyaki]

I'm not so concerned about failure as much as comfort and slippage.
