    Vintage Rear Derailleurs with 11t - 32t 9sp cassettes

    I'm going all anachronistic by putting a new wheel with an 11t-32t 9-sp cassette on my Austro Daimler Vent Noir II that still has its stock Campagnolo Nuovo Gran Sport rear derailleur. I tried shifting up to the 32t cog in the work stand for the first time yesterday and the top derailleur pulley is riding along the cog. I'm going to try and see whether moving the wheel further back in the dropout gives me clearance but I'm not too hopeful. I see that a lot of guys are running the Shimano Deore XT rear derailleur to accommodate a 32t cog, but I'm looking for something that fits the vintage of the frame a little better.

    Know of anything that has it all? Looks, range, clearance, dependability, and a reasonably affordable price (+/- $50)? Huret Duopar? Maybe something Simplex? A different Campy rDer? Or suggestions on ways to get the Nuovo GS to work?

    Here's the rear setup with the stock 5 sp freewheel:

    I'm running friction down tube shifters so index compatibility is not an issue. Running 52/42 up front, so should I also worry about chain slack take-up?

    Thanks!

    I have gotten an NR derailleur to work with a 32t max rear cog by pulling the wheel as far back in the dropouts as possible. But those dropouts were a bit deeper than yours look to be, so you're likely pushing it. Of course, you could always swap in a different crankset that's more of a compact double.

    Neal - was that with a 9-sp cassette? I've also been told that it can be tricky to get older derailleurs to span the full width of these wide cassettes before maxing out the range. Any trouble with compatibility on the small end? I'm hearing a lot of chatter when I shift onto the smaller cogs.

    I'd rather not change out the crankset at this time. I'd rather find this super-derailleur.

    Try a Suntour Cyclone GT, or a Suntour V-Gt luxe or Vx-GT.

    They can all handle the large cog and should have adequate range.

    Nope, it was with a five speed!
