well, do a degree it could show quality, as vivalo lost theirs when they had forks fail.

and njs stamped frames are generally made of a high quality steel. that isn't something that many would argue with.

so, an njs stamped bike will probably be a pretty good quality bike. that said, a non stamped 3rensho would be miles nicer than a stamped langster.

njs stamped frames are nice, but they just sell for an inordinately high price. i got mine for 360 plus shipping though so it's all good (what they probably should cost)
