Gorgeous. Quality builder; great tubing, great era. Nice find.
The Hampsten article has a good reminder of the 'save seconds on the climb and lose minutes on descents' Merckx quote. Let us know how this one rides.
Incidentally, the Sante group doesn't seem well loved, but check out the Disraeli gears site, whose owner gives it a very favourable write up.
Don't recognise the stem though(N for Nitto maybe?) Are there any markings at the quill end?
thanks Doc, I will read Disraeli. I liked the action on the Sante shifters. Someone on the Bridgestone group pointed out that the "N" looks like the Nishiki logo. Will swap it for a Cinelli in my bin.
The Dura Ace 7400 bb is asymmetrical which doesn't really suit the Shim 600 cranks. may swap those up for some 7400 cranks (which I happen to have on hand)
