I don't see anything 'Franken' about it. Replacing bits and pieces is normal. In my book, a Frankenbike would have an old steel frame, a mtb fork, mis-matched wheels, derailleurs from a third bike and handlebars/controls from a fourth. And colors wouldn't match anywhere. Yours looks like a nice old classic bike with a few more modern upgrades.

Just to add: I actually have a bike like described above. The frame was brazed together from pieces of 3 different bikes and it goes downhill from there. But it works.
