dx10sc comes up empty on the KMC website. ????
so i'll guess that it is some kind of KMC 10 speed chain. IME, nowadays, KMC does not advertise any chain designed for multi speed bikes to be re-assembled with a pin that has been pushed out by a chainbreaker. that doesn't mean that you can't remove links with a chainbreaker. but you most likely will need to reassemble the chain with a master link.
