Many of the second hand NJS frames have dings on them, which means they're no longer fit to race - at least with the NJS certification.
Also means they have been crashed
but it's awesome to own (the more battered up ones) as someone else used it for intensive use on track making the previous life of the frame a track-racing breed.
