Good morning, I'm looking for an integrated handlebar with a stem similar to the one in the photo, i.e. with a stem inclined upwards at least 17°.  I ask you experts if any Chinese manufacturer produces them.  alternatively I could also put separate handlebar and stem but I would like to keep the sheath passage completely internal, also in this case I would need a 17° stem but with internal cable passage.  or another alternative would be a mtb style raised handlebar i.e. rizer.  If anyone can help me I would appreciate it very much.

good morning I would like to know if anyone has experience with this bar.  I would like a license plate on my Orbea Oiz.  The sturdiness scares me a bit, I weigh 90kg and I do sometimes very technical and disastrous routes, I wouldn't want it to be fragile.  can you give me some advice?  Thank you.

Good evening everyone, I've been following this discussion for a while, and now I'm also considering buying a no-brand frame.
I have already had experience with the mtb in the past, I had 2 front frames arrived from a Chinese site, the thing was still in its infancy about 10 years ago and my experience has been very positive.
now I'm tempted to try again with a bdc frame, but as was the case with mtb, chinas are narrow in size.
I'll explain better.
I'm about 1.90 tall and having a tall crotch and a short torso, I pedal high on the saddle, but at the same time I don't like too much difference in height between the saddle and the handlebar due to back problems, in fact I still have a specy roubaix which is an "endurance" bike.
Now I see that all the brands make road bikes named like this and are characterized by geometries that give a more comfortable posture
basically they have much more STACK and the head tubes are longer to give a higher starting position.
Seeing the geometries of the most famous brands, I got an idea of the measures I'm looking for, BUT here I discover that the various Chinese brands with measures don't abound especially on the front of the bike.
My question is, has any of you seen any Chinese chassis that might have the characteristics I'm looking for? also gravel.
If yes, could you recommend some? Thank you.
