The NJS standards were set in the late 1950s, so with most things the parts stamped are pretty low on the perfomance level. They are nice, but will not perform like modern parts. There are three exceptions: bars, hubs, and cranks.

But with the bars and cranks things are changing. Parts like the 3ttt scattos and outboard bearings are making it so that in 5 years the NJS parts will fall the way of the Hatta headset and araya rims.
