KMC S1 chain (formerly Z410)
The KMC S1 is a no-frills track chain.
They're also so affordable, you can get a bunch of gold ones and wear them all around your neck like Mr. T!
FYI: KMC recently changed the name of this chain from Z410 to 'S1'. Same chain, different name. Some packaging may still show the old model number.
