I'm not getting the large tire size requirement, especially the 2.0/55 mm slick for a group road ride. I would not want that large a tire for that type of riding, 32mm would be tops. At some point you fight the weight of the tire and 2.0 is a heavy tire and would certainly defeat the purpose of saving weight with a carbon frame.
As well, I'm not seeing a 2.4/60mm tire on a gravel ride that is replacing a mt. bike ?. I think you'd be missing things like a flat bar and front suspension once you try to take a drop bar bike into terrain that is overly technical, which is why you want 2.4" ?.
I'd stick to gravel riding with the built-for-that-purpose bike. 45mm tires tops and then you've got a ton of frame options. I too would skip carbon, I could see Ti for durability and for a build up from a frame I'd look at a Habanero disc. It'll take a 44 mm tire.

Nice, I can get a pre-rusted drivetrain!

I'm looking at the Rawland ULV for this.... drop bar, space for 650b x 3.0 tires, lots of bikepacking mounts. After riding my gravel bike (Diverge with 650x2.1" tires/ or 700 x 44 Byways) I find I don't enjoy my trail MTB anymore. Always been a fan of drop bars over flat.

With sites today one can easily compare geometries and find a bike that fits their own personal fit and that would work for a conversion. I never argued that any bike would work only that it is not so difficult to do as many might think AND one can always change back if they do not like the new ride. It's certainly not for everyone as most people cannot figure out a proper fit whatsoever and I mean people in the industry that sell the damn bikes, not just the users.
Mtn bike geometry has changed so much in 30 years that it has now come back full circle to where it was when it first began. All this 'new' slack geometry is exactly where it all started back in late 70's.

I don’t know about that. Set tube angles are steeper and frame reach measurements longer than they were 30 years ago.

Both in wheel size and actual geometry, the entire industry is in its second rotation of the circle with regard to mountain biking.

Show me all the MTBs from these times with 29” wheels, 76-77 degree Seat Tube Angle, 65-66degree Head Tube Angle, ~450 mm frame reach and 24” ett for a size med. Because that is where most new MtBs are at these days.
The only mtbs these days that look a bit like 1990s geo are XC racing bikes, but that is not a return to anything, they just never changed much over that time. But this is still different from what you find in the late 70s.
Apologies for the thread derailment.

The 1980 headtube angles might look mundane in 2020, but that's about it.

Not carbon, but steel. Black Mtn. Cycles is working on a frame that would meet qualifications on tire size.

The reason you are getting “drop bar MTB” suggestions and not “fat tire road” is the tires vs. the drivetrain. In order to fit a 2x11 road drive train with the derailleur cable pull to match brifters, the chain line and Q factor limits the tire size. There might also be brake cable pull or mounting issues. Everything associated with 2.5 tires is heavy duty MTB stuff. There are bikes like this, they have been mentioned. But it’s a smaller niche.

The Open WIDE might be a consideration, but to fit their 2.4" tire capability they had to limit it to 1x for the needed clearance between tire and chainring.
