I've installed 4 cockpits from Aliexpress "Airwolf official store" in 36cm wide, 2 different stem lengths (80&100). I've ridden myself c.1000km on one, including sprints (note: I suck at sprints, can't do more than 1000W). The model is the HB009, which is (allegedly), FULL T1100. I weighed them at 333-350g. I also got the carbon garmin mounts from them (you need to use loctite on the threads btw, otherwise road vibrations will send it flying).
They're super stiff, they were reasonably simple to route (only routed 1 brake hose, though, running er9 as a group), very pleased.
Importantly, the stem cap is FLAT, which means you can play with stem height WITHOUT having to cut the steerer (something you can't do with the velobuild bars for eg).
I paid 75 usd a piece (w/o shipping) including the garmin mounts.
Very pleased, and happy to recommend at this point.
