i've run cockpits from Airwolf on aliexpress (dont buy their frames though) and from Peter from Xiamen carbon speed.
I trust both. In fact idk if i can tell them apart. I dont think Peter made the model i have, and i think airwolf is just reselling someone else's stuff.
Speeder is very well regarded when it comes to handlebars too, lots of boutique builders use them.
Depending on how much you weigh, be wary of ultralight options, as they are known to be very flexy. You can't beat material physics. Thinking of Darima and the likes. Also, if you crash, it's dangerous. A friend had a cat encounter and said hello to a curb during a max effort on the flat, and broke his cockpit. But he could still ride with it, the thing didn't just snap in 2.
Also, my 5 cents, but consider 36 or 38. I have wide shoulders and i run 36, it's just faster and it's fun to ride past your friends, them not understanding why you're overtaking

It is such a known cheat code by now.
