Do YBN last? I have bought PYC chains from Ali which are supposed to be good, but have heard most Ali chains are junk that don't last.
I've been buying only Ali chains for about 3yrs.. KMC seems legit, as long as you buy from the right stores, I went through 3 chains which lasted around 8-9.000km on my Tiagra 10s
then I decided to try YBN, and it was working really well. I rode about 3.000km and the wear was minimal. Got a new bike so the 10S is now stored and for sale
oh, always keeping the chain clean, lubing each 150-200km at least, deep clean each 800-1000km
