One of the most extensive chain tests was run by Wippermann. Of course, an in-house test, their chains were on top.
Now, I tested some Wippermann chains a while ago. I need to do more testing, but I started blowing out cassettes after switching to Wippermann. I need to watch that more and try to figure out what apparently happened.
KMC also has "e-bike" chains which I'm not sure made the test.
