You're saying the standard 1" quill stem is too large to fit into the steerer tube?.......If that's the case, then all I can say based on my experience is that a lot of Schwinns of the '70's and '80's had this same situation regarding the stem/inside diameter of the steerer. And most of the forks, maybe all of them, were Tange forks (again, Tange made LOTS of forks, so a lot of them didn't have the odd size I'm talking about). As far as I know, the only other thing that's not standard about the Schwinns I'm referring to is that the large locking nut on the top of the headset assembly will have an inside diameter that matches the .833" stem, in other words it's slightly smaller inside diameter than standard. The threading on the fork steerer, the headset assembly, etc. is all the same as the standard 1" size. I've never heard of bikes other than Schwinns using this odd size, but that doesn't mean it's not so, of course...........Is it possible a fork off of a Schwinn was put on your Nishiki?
