Indeed, I saw the shifters listed as " top mount" and thought they meant up by the stem which I wrote off as a mistake, good for you for recognizing they meant those short -lived aero things. I also saw the aero reference to the rims(these would have been a very shallow V rim--not like aero rims to come) but didn't go back and check your pics. The aero rim thing stuck out to me because I was starting to believe that the top tube sticker might have said "Criterium" and such rims wouldn't make sense (really, any clinchers might be second choice on a crit. specific bike). Now, I'm not so convinced that the decal looks like criterium. Glad you posted this--I spent roughly 78--86 on top of a road bike. I started out on Italian bikes (and a Spanish) and became a convert to Japanese--thought I knew most of them and yet never heard of Zebra(kenko), It appears that if you were active in cycling in the East the brand would have been known to you. Now, I officially throw in the towel.
