I assume this was a late 1980s bike? So the RD would have been Mavic 851?
Yes, later 80's I think, This bike came from Peugeot with the all silver clear anodized 630 crank and the also all silver 801 RD/FD set, and the all silver, clear anodized brakeset sourced from Modolo. So not the SSC group, but it's really just the dark anodizing and some white "SSC" silk screening that makes the SSC components....SSC, otherwise, the 801 and 851 SSC RDs are pretty much identical under the anodizing, Same goes for the crankset..... Remember, it was the early/mid 80's and dark anodizing was believed to add an MPH or two to you bike, every time!


Here's the 801 RD/FD combo as mounted on my Peugeot PSV:
