who makes the bike chain?

[e-rider]

I'm trying to work out who makes the bike chains for the big companies.

I understand that most/all are made by either KMC or YBN.

So,can anyone put a kmc or ybn next to the following:

Shimano
SRAM
Campagnolo
Whippermann
Connex
Clarks (YBN)
etc.

I don't know TBH, but I wouldn't have thought KMC make chains for Shimano. My reasoning is that KMC are championed for their quality and lengevity whereas Shimano ones are not. Of course KMC may make a cheaper chain for Shim and keep the better ones for themselves I suppose

Connex is a brand name for Wippermann bike chains and they're made in-house.
