I have a friend who rides XC and cross at a reasonable level. Both his XC and cross bikes are generic chinese frames and his cross wheels also. He’s had no issues with any of his kit.
Getting back to my chinese road frame and bars, it’s handled the ripped up tarmac on alpine descents 3 years on the trot and there are some big holes coming down the HC side of the Joux Plane.
I also run a 90mm tub chinese front on my Scott Plasma, it’s been a solid purchase at £150 delivered.
I don’t have tons of cash to throw at exotic gear so I make it stretch where I can.
The Chinese stuff is ok but I’m still reluctant about fitting some to my Enduro as I’m not sure they’ll survive a half decent off, saying that, a nice light ally pair probably wouldn’t fair much better I guess.
Undecided.
