Yes, that's Carbonda's integrated handlebar. It does make for a bit of a guessing game to get reach and width both correct on a new frame - but in my case, it happened to work. Only (extremely minor) quibble is that the top cap is a different matte black color than the frame/fork/seatpost/handlebars.
The bike ships with 1x 10mm and 2x 5mm spacers. Fortunately, the FSA ACR 10mm spacers (I'm using 5 here - will dial in exact fit later) are back in stock in their store for $4/each.

Routing hydraulics was fine. I used a fishing kit & electrical tape. If not for the kit, it probably would have been Very Hard as the hose is not very flexible and there are a couple tight turns.
As an aside - it's tough to keep slack on these hoses within the frame, but there is some play on the routing inside the handlebar to hold some slack. I presume the hose just bends horizontally within the flat section. That's great for me, since I don't want to have to recut the hose if I remove spacers & adjust height. Also the spacers all detach in the middle meaning you don't have to completely disassemble everything to add/remove one or two.
I'm using the $10 headset that Carbonda sells - and it also works great. Pretty sure I wouldn't be able to tell the difference between this and a name brand version.
We didn't have any real assembly issues. The flat mounts for calipers were faced correctly & even the pressfit BB went in smoothly w/o any creaking (yet).
Overall, the frame, fork, seatpost, handlebar combination is a pretty incredible value and the ride is pretty compliant. I'm super pleased.
