Hi, I had to buy a YBN chain recently during an emergency as this was the only option. I have never heard of them and couldn't find any reviews online either. So far I have ridden about 100km on a F700GS and it seems decent. My plan was to make it home and then order the DID I usually buy. But to be honest I was surprised it did not look as crappy as I expected and has responded ok so far. So I am thinking I may keep it for a little longer to see how it manages. Anyone has any experience with the brand?
