I think '92 would have been the ONLY year with both brifters and dual pivots as 600.
I didn't know that Ultegra had a tri-color version (it must? I never saw it).
Since the tri-color started in '88, wouldn't any 600 group bike between '88 and '92 have tri-color, or did they have a different 600 version going in parallel?
