• The paint quality is excellent. The molding quality also looks extremely good - I'm not poking around with the endoscope due to time constraints, but the entire downtube + headtube look perfect. The brake mounts and BB shell are also faced. There's a tiny bit of clear coat overspray on parts of the BB shell but 2 seconds with a knife and off it comes, so no problems there.
• The frame and fork screws are not set with rivnuts that protrude above the surface, so all the mounts are flush with the tubes. I don't really like this, as it invites paint damage since there's not much contact between the screw heads and the frame/fork. I'll be using some spare M5 titanium washers for load-bearing bolt installation (mainly the seattube bottle cage), and might switch to nylon ones if the paint gets marked up with installation.
• The downtube storage hatch is a tight fit with a rubber skirt around the edge, so it should be pretty weatherproof. The included bag is nice and slim and should be no issue, though I haven't packed it full yet. It looks like I can fit my packable jacket in there too which will free up a lot of room in my handlebar bag. Downtube storage sure is nice! The included multitool lives under the hatch, but I'm not using it, and the mount for it comes off when the (extra-long) bottle cage bolts are undone, saving some weight.
• There are molded-in channels on either side of the hatch to run cables/hoses through to keep them out of the way. Very convenient, but they're a little tight, so I don't know if I'll be able to run foam housing through the channels or instead use 2 segments, one on either side of the channel.
• A Soma Further 36oz bottle (the biggest bottle I use) doesn't fit on the seattube using the stock mounting holes, but I anticipated this and bought a slim bottle cage extender, and dropping the holes down about a centimeter allows the bottle to just barely fit. This is what I was most afraid about, so seeing this setup work is a big relief. A side-loading bottle cage is mandatory though.
• The included seatpost looks like it should be pretty flexy. I'm not using it on this frame but I might put it on my commuter bike.
• The seatclamp is branded QUICK, so clearly Carbonda is reusing their design from Quick Pro. I haven't heard anything bad about those clamps, so fingers crossed. The listed 8 Nm torque seems a little high, I'm going to start with 7 Nm which is what I've been using on my current frame to no ill effect. Again, a dropper makes life difficult.

• The only flaw I could find on the frame, or rather in the frame, is that the ends of the channels that divert cables/hoses around the downtube storage hatch opening have some excess resin from when they were bonded in, and this resin has cured to form mildly sharp bumps. They aren't big, probably only ~1 mm high (I can only feel them, there's no angle to view them), but it's necessary to use foam housing all the way up to the channel entrance to avoid potential hose damage. The channels aren't big enough to accommodate foam housing though (at least not easily) so some careful measuring is needed to get the foam housing length right.
• Part of my decision to buy this frame was that it listed 160/180 mm rotors - but this is only true for the frame! The fork is 140/160 mm!! I'm not too happy about that, but I can live with it for now. I bought one of the cheap 180 mm adapters off Aliexpress to see how that works, maybe I'll keep it, maybe I'll spring for the Peak Torque BBC ($75 though...). I also emailed them about this and they've corrected the frame specs on the AF website to be more clear, so kudos for a quick response there.
• The internal frame storage is somewhat limited - the included bag is good and is a snug fit, but no object longer than about ~3 inches can be put in the bag lengthwise, because the bag needs to be able to articulate to be crammed up into the downtube. It can't go down towards the bottom bracket because of the below-downtube water bottle cage rivnuts. The bag wasn't large enough to fully contain my (slightly overkill) tool kit, so I split the lesser-used tools into a separate ziploc that I wrapped in two shop towels and wedged beneath the hatch. This worked well and there were no noises even on some very washboarded dirt, and the bags haven't moved a millimeter. Unfortunately I can't put my jacket in the downtube, it won't fit unless I take it out of its protective sack and I don't want it to rip.
• There's no clean way to plug the hole by the bottom bracket for front derailleur cable routing. Ideally a little rubber plug would be included to patch this up, as I'm sure many, if not most, of the buyers of this frame will be running a 1x setup. I used some Sugru to seal the hole but a first-party method would be preferred.

The build is done and I took it out for its first shakedown ride. Somehow I nailed the fit just by vaguely replicating the dimensions I measured from my G068, so I didn't even have to stop and adjust anything, and 7 Nm on the seatpost clamp is plenty. I don't really have much to say about the build process. Everything was completely fine (except dealing with the hassle of a dropper with internal routing, seriously, don't do it), all the surfaces were faced and all the threads were clean, hoses popped out where they should, it was great.

I do have a few notes about the frame, though:

Overall, it seems like I got what I wanted: nearly the exact same geometry and handling of my G068 but with superior manufacturing quality and a few additional features. And the fork doesn't creak!!! I only wish the seattube was a bit longer so I could've kept my OneUp dropper, PNW is not the same quality. Oh well, can't have everything...

From the early videos of the eurobike show, the downtube looked massive and they had a minitool and a small pump latched to the storage door lid and had shoved a bag up the tube. If you say there is not enough place for tools longer than 3 inches then the storage compartment is not really serving its purpose.

If they do not put the channels for brake hoses moulded into the frame, would there be more space for the storage bag?

Also, after you take it out for a ride, please tell us how it feels to ride.

What did you use to replace all the mounting point screws? Also Sugru?

Hi! I was trying to get photos of complete bike for size "S." Could you please add more photos? What does it full look ?
I've been thinking about ordering one for a while, but I'm still unsure about the large sloping/short seat tube.
