That's interesting, I think it well predates the Triathalon trick of fitting 650C wheels to Tri bikes for faster acceleration and aero blah-blah, cause this is a Japanese '80s product and the wheels fit the frame/fork and brakes. And no Tri-geek handlebars, perhaps it's just intended for shorties, juniors and females without resorting to the Terry small front wheel. I'd flip it (complete) to a petite female, it's bound to be the answer to somebody's prayer.
