Btw, those 200GS shifters and derailleurs worked pretty good for a system so old. How high stood they in the Shimano component ladder (back then)?
200GS was in the group that was bottom of the line... err... I mean entry-level at the time. I believe that there was only one step below 200GS... the 100GS. I remember my brother buying a 1990 Specialized HardRock that came with 200GS. It was a pretty decent group actually and to be honest, I feel that it was a comparatively better low-end group than today's low-end groups. In today's pecking order, it would probably stand in around the Altus to Acera position.
