Ah, thanks for the info on the build, I am hoping to find as much out about this bike as possible.
It's amazing, every single bearing race lacks any wear whatsoever. This bike is basically NOS, with exception of the paint, but that tells me it banged around in a garage for the last 24 years (if it is indeed a 1984 model).
Rebuilding it has been a lot of fun, I had a Nishiki in high school I had found in the bushes (painted extremely poorly with latex house paint... So I'm pretty sure it was stolen), unfortunately due to family issues and being sent to a boarding school in California I never finished it.
A question...
Where is the best place to locate a Sugino crank arm cap (the ones that cover the spindle), as I am missing the non-drive side cap.
