Okay, the deed is done. I created a tabbed washer by grinding and bending a 3/8" fender washer. Details here and in following photos:

Thanks for taking the time to document this, @smontanaro !

I, too, found shifting with the Huret Jubile to be vague and overall not confidence-inspiring. And I have a short cage model!

I found myself not riding the bike it was on due to the shifting being so poor. I was constantly feeling like the derailleur was going to go into the spokes or catastrophically fail in some way.

I've got the Huret dropouts as well, but I just did the simplest thing and made the bike a fixed gear

I had a friend back in the 70s that did this modification to the Huret DOs on a Stella in order to run a Sun Tour Cyclone. It worked great … for a while. He eventually broke the derailleur hanger where it was drilled for the set screw.

Would a Wolf Tooth Roadlink work?
You could have the added (codger) benefit of swapping in a 36- or 40-tooth freewheel.

^ Perhaps, but wouldn't it want a Campy-compatible dropout as well? As for 34/36 cog compatibility, I suspect either the original Huret Jubilee or the SunTour V-GT derailleurs could handle that or get close. I tossed on the current freewheel just because it was handy and better than the corncob the bike came with.

The Jubilee won't handle a 34/36 combo. The biggest freewheel sprocket the Jubilee can handle is 28 tooth. (Disclaimer: there's always someone who says they ran a larger freewheel than 28 tooth with the Jubilee RD but that's not recommended)

Years ago on a 72 Le Champion I ran a Stronglight 99 crank with 52/36 tooth sprockets and a Jubilee front derailleur in combo with a 14-26 freewheel and a Jubilee long cage RD and it worked pretty good.

smontanaro 

Is that true also for the long cage Jubilee? Did Huret create dropouts with a larger drop for the derailleur pivot? If so, would that have been used in the Grand Jubilé frames? (I'm pretty sure SunTour produced a touring dropout. It seems unlikely that Campagnolo did, at least in the 1010 series - I think they were focused only on racing.)

I'm reviving this old thread because I recently stumbled onto an Ebay seller's listing for a batch of Huret-to-Campagnolo rear derailleur adaptors. I have no connection with the seller. They're for sale individually at what seems to me to be a pretty reasonable price:

Not a lot of them left, but here's your chance.

I was also interested to learn that the part in question is apparently called the "Huret 2364 stop plate." Potentially useful to know if I ever have to search for another one down the road sometime.

I know this is an old thread, but for me the simplest solution is to use a DuoPar rear derailleur. Shifting is as nice as with a Suntour.

Here's my Jubile in Reims:



The bike is next to the Canal between the Aisne and the Marne, a few KM from Reims.

I like Duopars, too. And they do work well on Huret droputs--provided that you have the special tabbed washer made to fit the Huret dropout. There was also a different washer that allowed Duopars to work with Campagnolo dropouts. At least that's been true of the ones that I have owned.

That was a neat piece of design, in a way, but since the little washers aren't integral to the derailleurs, they're easily lost of mislaid. At least half of the used Duopars I encounter come without either washer, making them unusable unless you can find or fabricate the appropriate tabbed washer.

That is useful information, thank you!
