I had missed that post in January!
I just want to add that I prefer to stay on the safe side when dealing with Chiner parts. I never go for the lightest. I get 2 hardtails. My 29" is 1300g and extremely solid. My wife has a 27.5" that is 1100g and I can really see a difference in solidity. It's fine as my wife stays mostly on the road and rides slowly
but I would not use it on my trails.
I don't mean all light Chiner frames are fragile, just that the risk is higher.
