maybe 80s
yeah, I dunno anything about this so that's why I am asking. Sry I have no photos. I am assuming not every fork fits every bike. I am wanting to know what these fork types are called. The frame steering tube has outer races at the top and bottom where ball bearing sit between them and the pressed on fork inner race and the headset hardware's inner race.
sry there is no pics, myb I should move this to the mechanic forum?
