I've bought Chinese carbon bars cos they where cheap enough to take the chance. After a good inspection I am perfectly happy with them.
I bought Columbus carbon forks for 200e and to be honest I would probably get the Chinese ones if I was doing it again.
But if you are going to be worried about them failing you can't buy them because you won't be able to let her ride the bike in good conscience.
There is always going to be some doubt with any new part till you have got some miles on it.
What does she think?
