Hi Harry,
I sure do remember Mages....all three (or was it four?) floors. Bought my first cross crountry skis and bindings there. I used to wrench on bicycles back in the late 70's for Cycle Smithy on Clark St. I've seen plenty of Motobecanes along with Peugeots and some of the first Cannondale aluminum bikes. Gosh, there used to be thirty or more bikeshops in Chicago back then... Kozy's, On the Route, Oscar Watzyn's, Belmont Schwinn, Sportif, Buckingham, Turin, Park West Schwinn, etc... If you guys ever get nostalgic, check out the vintage bikes at Cycle Smithy 2468 1/2 N. Clark St. Owner is Mark Mattei who's something of a heavyweight among vintage bike collectors. I've worked on a few of his pieces including a couple of Bowden Spacelanders
BTW, he has an absolutely jaw dropping collection of promos and car kits. Oh and a top notch slot car collection.
