After receiving my X10 chain from Cambriabike which was marked "suitable for Campagnolo" I sent Cambria an email. I asked them if this was a alright for Shimano. They just replied saying that Shimano had different specs and to call them. The problem is I already put it on the bike. I'd like to which one of the KMC chains, the Campy 10 version (the one I received), or Shimano 10 would be better for my Shimano 9 speed? I hope that's not too confusing.
