I think this is a 1986 Schwinn Letour. I cleaned off the front hub and it said Schwinn Approved 86 France and the components are a pretty good match for when compared to the 86 catalog.

Tange semi sloping fork, Stronglight crank 40/52t, Huret Rival FD, RD with Huret levers, SR Laprade 26.6 seatpost, Weinmann front rim and Diacompe brakes. The serial number is SA610703, not sure if that fits.

Rear cogs are not a match nor is the rear rims (although, like the front rim it's made in Belgium).

So, might this be a Japanese built Schwinn for/from France?
