Today the Specialized Aethos 2 was just released, and it is a nice comparison with this bike. Non-aero, superlightweight. Specialized has increased the stack, so it is roughly 15mm higher across the board than the LTK266-D-SL (dealbreaker for me, tbh). But it now has UDH and support for 35mm tires with 6mm of clearance (CEN Standard) just like the LTK does.
But I bring it up because the Aethos 2 Pro with SRAM Force E1 comes in at $8,499 before taxes. In a size 56 with no pedals and 28mm tires, it weighs 6.71 kg.
https://www.specialized.com/us/en/aethos-2-pro-sram-force-axs/p/4221564?color=5466393-4221564 My LTK266-D-SL with full SRAM Force E1 cost $4,700 including taxes, shipping, duties, and all the rest. If I was more frugal about touch-point components and wheels without compromising on group/crankset, it could have been more like $4,250 -- so fully half the price of the Aethos.
My LTK in size 56 with 250g 1stgen Assioma Duos, 50g in bottle cages, 20g in computer mount, and 35mm Michelin Pro5 TLR (400g each compared to the 275g each of the 28mm S-Works Turbo TLR Race Tire on the Aethos2) comes in at 7.1kg. So no compromise in weight.
I bet the Aethos has a comfier ride. Resell value is incomparable, as is support from Specialized dealers.
But at double the price even with a spendy retail buy of new Force, it's an object lesson in the value proposition of these open molds, at least to me.
EDIT: I wrote all this froth, but really let's just think about the frameset: $3,499 before taxes
