I didn't order bars. I haven't had any issue with preload on headset and only a small issue with getting my stem on. The steerer was a bit thick right at the top. Once on, no issues. About 100 miles in and so far so good.

Other thoughts:
The seat stay are wide (duh) and when stretching out the back of my left leg hits the stay. I don't really have the issue on the right, but I think that's just me.

Also this make mounting a rack to the mount points questionable for me. So I'm getting an adapter to go around the seatpost to mount a rack to.

The storage door still seems too soft and there is not a good seal to the frame. Water and dust find their way in.
They said they would offer the door and part separately, but I'm not holding my breath and will try to baby the door, hardware, and opening. I'm going to add some foam type tape on the door to act as a gasket. There is some, but it's not enough. I don't want to add to much because I don't want to be d the door.

It rides like I expected. Which pretty much means I don't notice anything about the frame. Seems stiff enough and comfy with 55mm tires and a redshift seatpost.

55mm tires have a lot of clearance at least 6mm at any point I thought to check.

I'm seriously considering buying the brake mount surfacing tool I saw on YouTube from Ali. I have a couple of bike that I would feel better about knowing the mounts are flat to each other and 90deg from the rotor. My current windows for no rub seem incredibly tight.

Man does my gloss paint seem to scuff easy. The section right about my downtime bottle cage is hazy. I don't remember missing the cage that many times or grinding my bottle into the spot, but 🤷‍♂️

Seatpost fits well and didn't over torque. Only 6nm. On that thought I haven't seen any torque specs or directions for the build. So have been using standard from parts and other sources.

I have a stages power meter crank arm and it clears the frame with about 0cm. Very faint scuffs after the first 20 miles. I added a 0.6mm shim and no issues for hitting the frame or wobble on the crank arm.

I'm adding helicopter tape to protect from rocks/grime spraying off the wheels and around the crankset to protect from the chain if/when it slips.

Other thoughts since I'm taking a break.

Took 40 days from order to delivery for a M black gloss frame (no seatpost or bars) which I think puts it at 10 days after Ali said it shipped.

My fork looks ok. Not "polished", but ok. looks like the excess filler/epoxy around the brake hose guide was scraped off with a grater. No exposed carbon thread or anything that makes me think unsafe

The storage cover is plastic. The locking handle is plastic. The inserts at top and bottom of opening are plastic and they fill the interior opening above and below the storage opening. I'm thing of cutting them down to just what's needed to hold the door. Then I can push a bag down toward the BB and one up towards the bars.

Paint seems ok, but the plastic bubble/foam wrap they used left a noticable pattern when you look at it closelyon the paint. I tried to was it off thinking it was grease or residue, but it remained. Not sure how it will look after it goes through some rounds of getting dirty and getting washed. I'm not too worried about it, but if you want a perfect smooth/shiny gloss finish it would be frustrating.

They did not face the bb, or it was painted afterwards and just part of the insert was not paints. I was able to install the bb fine and it seems to line up.

The brake mount points also were not faced and had a large bump of paint around the outer edge of all of them. I sanded them down by hand using a Dremel cutoff wheel. The paint seems relatively soft.and I got them much flatter than they were. I'd say flat

Cables through the headset are a pain to run even without the integrated bar and stem.

Looks like 2x grx 11 speed 46/30 is fitting just fine.i have a tire on measuring 47mm right now and seems to be a couple of inches of space to the front derailleur. I plan to run some 2.1" that barely fit in my old frame and look like they will have plenty of room. I got some parts expecting to have to build this 1x for a larger tire clearance, but doesn't seem necessary.

Front triangle is smaller than I realized and my frame bag won't fit. My existing seatpost may also be too short for me with the min insertion on this frame. Top tube is more sloped than my ican x-gravel was. Otherwise this geometry lines up pretty well to my previous 560 ican for reach. Hoping to get 2 bottles and a frame bag in.

The thru axles don't match each other. The front is a v profile on the head and there is a v shaped brass washer that falls out almost every time I have removed the thru axle. The rear is flat at the head and no washer.
 
Frame and fork came in on the heavier side of the +-. When I ordered the frame was actually posted at 1050 for a M and now states 1100.

Routing the rear shift and brake cables took a while for each. The front brake cable just slide right through the guide as expected. Front shift cable would have been a lot easier to do before installing the bb. But got it with help of cable guide on first try. Full length cables for shift and brake

Oof. I forgot about that. And dustedrob's fork at the top of that page is pretty rough looking as well.

Do spcycle forks all look like this? I can't really tell from there website, but they seem to look rough there too. I saw one other pic in a thread here, the g068?, where someone has a pic of the steerer tube and the brake cable port where it doesn't look very nice. It may be the lighting? The fork complaints are about the flip chip that this fork doesn't have.

Weight seems good. Those are some rough looking forks though. The voids and pits seem worse to me than the hack job on the surface (if the carbon is thick enough there. which I'd hope it's reinforced for the cable routing hole in it) Certainly makes me question what is deemed acceptable in their QA.

I inquired about my order status via ali express messages and got a reply back same day that it will be delivered in 3 weeks. I'd be pretty happy with that as they haven't seemed to have even shipped it yet.

My ican x-gravel in L looks to be about the same as the g028 in M The hub on this is about a cm lower and relationally the seat and bars will be about 1cm more towards the front. So I'll be further forward over the bb, but this has a bit more trail. Could be minor and meaningful changes. I'm not expecting it to feel much different though.

I'm more worried about shipping time and QA at this point.

I was told if ordered now shipping mid June.

I was told late June 2 days ago. Was hoping for expediting to early June, but doesn't seem to be an option

I was also told that they'll supply headset and spacers to support standard bar and stem instead of integrated
