Superbike. Not even! Throw that junky Crane derailleur away and get with the slant parallelogram program man Looks sweet with all that black trim! yumyumyum! And the sun bleached stickers! Love it Hi Bowie; welcome to the forum! FWIW This particular model of Viscount was the top of the Viscount line; I suppose that is why it is called Supabike. It has been a long while since I have heard comments on the 1970s Suntour slant parallel design versus the Shimano dropped parallel design argument; great nostalgia. Since the 1970s the slant parallel design has dominated the world of derailleurs; so it must be a superior design, right? I have bikes with Suntour, Shimano Crane, as well as Campagnolo NR of the era. Perhaps I am some kind of clod as I cannot discern a difference between the shifting of the Shimano Crane and the Suntour Vx (or Cyclone for that matter). They both shift slightly better (maybe) than the Campagnolo NR; nevertheless, I find all three (when using a modern Shimano freewheel) to be totally acceptable. In the 1970s Japanese components were considered (at best) to be second tier (even if they shifted better). The term superbike was not (to my knowledge) used in the 1970s; if it were to be used, it most likely would have been applied to a nice Italian frame with Campagnolo components. All the Best Jim

Ah my tongue was firmly in my cheek when I recall the thick heavy debate of rear derailleur design For what it's worth my other bike has a set of 600ex stuff on it, (6200ex rear derailleur) And it shifts fine. On modern cassettes (7/9 speeds etc with narrower gear spacing) I find you do have to be careful next to a derailleur with a nice slanted body as it tends to skate a smidgen more, but it's no big deal really. One would have to ride them back to back and concentrate. Old Dura-Ace parts must be nearly junk $$$ money? I'm to scared to look.
