That's a serious concern... I agree with the trend here. No Chiner bars for me. I don't even trust 100% my branded carbon bar. But Aluminum is no better, they nicely break too
Still, you need a serious flaw in the manufacturing/design of this bar to break with a 43 kg rider and at 660 mm length.
I also own 2 carbon rigid forks (Chiner), and don't have 100% trust in them, even though they really look solid. Well, if I really think about it I don't have 100% trust in any carbon part, chiner or not. A friend of mine just got his FS carbon frame replaced because it started to break around the BB, and it is a top brand.
