Unfortunately I can't post anything yesterday. Seems like the Website has some problems. I still can't post pictures for some reason.

I was wrong about the hanger. It isn't screwed. It looks like 2.5mm hex but it is riveted.

Wendy did reply to me and tried to help we're she can. I really appreciate that. But she told me that there is only this hanger version. So I guess I have to go without the stabilizing screw and try to index it somehow. As I'm reading in other forum it is also like that to e.g. Basso frames.

In terms of internal cable routing, I finished that yesterday. With the right tools it was possible but not fun at all 

I don't know if it is normal but when I turn the handlebar, there is a hearable rubbing of the cables in the headset area. Should be normal I guess, because the cables need to move somehow when the handlebar is turned. It's my first internally routed frame.

It seems only recent shimano derailleurs have this "stabilizing screw". Don't worry front derailleurs work perfectly without this feature.

Now I glued the little metal plate from Shimano like this.
I don't think it will hold very long time, but the feature of the screw kinda works 

There would be also the possibility to glue (2k) a little metal plate onto the hanger. But I don't know if that is necessary.

I finished the Build today after receiving the wheel set.
I've also ridden the first few kilometers to set every adjustment and get a first feel for the bike. The build with pedals and bottle mounts is about 7,5kg.

The mechanical shifting works fine. It only needs some fine tuning. The bike feels very good and stiff. I have to say that I do not really have a comparison. Only my aluminum gravelbike (Trek Checkpoint). I'll also post my impressions after a few longer rides.

I think the frame fits me pretty well with size 54. I'm 175cm with inseem of 82. But after only 10km I don't know exactly.

My personal Pros and Cons so far:
+ Good frame  and parts quality. No bigger problems yet.
+ The build was good with some smaller problems.

- front derailleur hanger not so good for mechanical Shimano due to the missing support for the stabilizer screw.
- paint quality is okay (small imperfections here and there) but the clear coat is very thin so that I already have some smaller scratches. I think the paintjob should be clear coated at least 2 times.

As already mentioned by other people the carbon in some areas (downtube, toptube) Is very thin. You can easily flex it with your thumb. I don't know if that is normal for that kind of frames. I just want to say it.

All in all I'm very happy how it turned out and looking forward to the next rides. The whole build was about 2500 Euro. For that price I can't buy a branded Frame with carbon wheels and group set.

Short update:
I did my first 50km ride today with best weather.

It was great and the bike feels amazing.

The only thing I have to get used to is the Free hub sound.
As it is a 36T Ratchet system, the sound is not "round". It's a little alternating which seems to be normal with ratchet Free hubs. But for me it sounds not so nice. Maybe I'll put more grease inside to get it less loud 

It's LCs C52DB-RD28-44C wheel set.

I'm being very picky here...
