recently got this bike mostly to swap the components and wheelset (all SunTour Superbe Pro) to another frame. i've done many searches on Nishiki Track frames but there's not much info out there. frame came bare with no decals or model name callouts. had one sticker on the seat tube that says "SUPERBE PRO '85 World championship V9 KOICHI NAKANO" the serial number on the BB appears to be: 73 0042. there's also a "W" above the serial number. frame was purchased in the early 90s so it could be from the late 80s? has nice thin pointed lugs with the "Nishiki Crown". very light weight.
the Track Forks are stamped SHIMANO. the front Fork has no name or numbers but has "DURA ALL" stamped Dropouts??? some research on BF mentions this might be an Aluminum Fork sometimes used by SR or Glan Well but possibly not stock on this bike?
PAINT: for people with frame painting experience. either this frame has sloppy paint from the factory or its been re-painted at some point. especially around the BB there are thicker and thinner areas where paint has pooled or run a bit. the absence of decals etc would probably indicate this has been repainted? might just strip it down and repaint...
any additional info you might have would be welcome! it would be great to know something about this frame/fork - like the model year or type of steel the frame is made of etc.
