I have no idea, but I have a full first gen 600 groupset on my 1984 Raleigh Corsa.
I think mine is first gen 600, it has indexing and aero brake levers.
IMO, this group is the most pleasing looking - the tricolour and Ultegra versions look cheap by comparison.
This is the only bike I have Shimano on...perhaps there's a Shimano expert on somewhere?
