Hello, folks.
I bought this Nishiki in 1973, when the LBS owner convinced me that I needed to buy as big a frame as I could handle, which turned out to be 25", center-to-top. (For comparison, my main ride now is a 59cm RB-2. I can fit on the Nishiki, but the standover tends to make my wife nervous. . . .) The Competition, if I remember right, was just below the "Semi-Pro" (later renamed the "Professional," I think): the Competition had clinchers, the Semi-Pro had tubulars, but other differences I can't remember. The tubing is cro-moly, double-butted, maker unknown. The fork's included, but the headset almost certainly needs replacing.
You can see some black & white pics of the Nishiki at this url: http://my.voyager.net/
Price: $75 plus shipping. (I have no reference price to go by since I've never seen another one of these for sale. So I hope this is reasonable. It ain't a 1962 PX-10, that's for sure!) If you're interested, you can contact me off list at ferness261@voyager.net . I can send more measurements and other details, too.
Thanks!
