I've also noticed (through first-hand experience or photos from events) that I can't recall seeing more that one or two NJS type bikes at events among hundreds of others. And those few bikes were hipsters who were new to track racing.

Components that happen to pass NJS spec are dope. It's just the "all NJS" hype that doesn't make sense. I ride high-flange Dura Ace hubs and Dura Ace cranks, both NJS. I also have a NJS chain. There are several photos of Victoria Pendleton (UKs female star track cyclist) using Nitto 123 bars.

Folks gotta realize that NJS is to cycling is what restrictor plates are to auto racing. It's an equalizer.
