BianchiGirl, the shifters are suntour; I had them laying around as well, and fit well with the aero bars. original shifters were 105. The paint is nice, not aflat white but more of a pearl. I could'nt find date codes as to when the wolber gtx II s were issued, I know the 91's came with regular gtx's. Custom frameset build by LBS is a good guess; I did'nt think of that. I will try to get some specs on the componenst as to lend to the dates. I have been on vintage cannondale thoroughly; I find it a very nice, informative page. But again, I did not see the 91's coming in while (pearl white). Thanks for the help and kind words so far.
