I purchased a carbon frame from alibaba (hongfu fm-088) and am completely satisfied. ordered and shipped right to my door. built up with hand built wheels and di2 components. I wanted disc brake and thru axles and it was very difficult to find a used branded frame in my size with geometry and ability to use disc and thru axles. I couldn't bare to pay premium for new branded frame and with savings was able to equip with better components. I may have lucked out, but quality is definitely there and it is my only experience with china components and I would, at this point recommend to anyone.
