1996 R600

I like the colors. I don’t know much about the RX100 gruppo. If it is a 56cm frame I wouldn’t mind tinkering with this one for my wife. But looking at the head tube it might be much smaller. Not sure. It’s listed for $150 and is a 25 day old ad, so probably would take less.

Twin to mine! Ultra Violet to Black Fade, the colors used by Timex-Cannondale racing team back in the day.

It does look a bit smaller than a 56. My 56 has about three fingers-width between the top tube and down tube at the head tube, and that looks like less. Of course the serial number on the bottom bracket shell will tell you for sure.

RX100 was the next-to-lowest gruppo from Shimano at the time (I believe it was RSX->RX-100->105->600 (tricolor, I believe)->Dura Ace. RSX was 7-speed, RX-100 and up 8-speed, I think. I know RX-100 is 8-speed because I'm using the brifters with the 8-speed setup on mine( 600 tricolor and 105, mostly).

There's a guy out in California, I think it is, who offers refurb service to restore operation to certain models of Shimano brifters - RX-100 among them. He turns them around quickly; mine work fine now.

RX100 gave up very little in performance compared to 105.
