Well now I have another Nishiki I'm unsure about. It appears to read "Competition" on the top tube, and the front hub has "80" stamped on it. But after searching around online and in this forum it seems there was no Competition in 1980. Regardless, it's a sad bike but hopefully I can bring it back from the dead eventually. I mainly like the cranks and shifters.
