Probably quite a good, durable chain for SS/internal hub use. It's a BMX chain. It has beefier side plates than multi-speed chains and is a bit heavier. Worth noting that chains do not wear on the side plates but rather on the internal flanges of the 'psuedo-bushes'. The metal here will be no thicker than on any other chain. Long wear is going to be all down to manufacturing accuracy and metal hardness.
