I might seem suspicious, but the snippet on Pinarello seemed suspicious. They show the test on a counterfeit frame, but then show the result on another frame
It was quite a weird video for me. Obviously, there is a massive conflict of interest. It would be unreasonable to expect Pinarello to say "sure, buy fakes/Chinese frames, they are (mostly) safe," they must protect their business.
Some other questions that were popping up in my head during the video were - did they really buy a fake for 3-5 second appearance in the video? Or do they regularly buy fakes? Did they really show a fake or just a result of a random QC fail in their department?
I find these videos of little value, not because I believe that all Chinese frames/fakes are inherently safe, but because of a very clear conflicts of interest which must determine the narrative.
