I'm pretty sure I already know the answer but is there anyway to do it without drewing the hanger? Then again, would it technically be "drewing" if said Simplex hanger was on a straight and rust free French mid level Reynolds 531 frameset with bad paint, bad chrome and bad graphics with no hope of ever being cosmetically restored? I have a '73-ish Gitane TdF and a '77-ish Peugeot PR-10 frameset that both fit that description and only enough good Simplex pieces to build one. I just got a pretty decent buy on a mechanically sound but less than beautiful Huret Jubilee RD and DT shifters and thought it might be fun to use them on the other paired with an even uglier Zeus FD and Zeus brakes. They're extras I got when buying Zeus parts for the '72 Raleigh Competition.

...are you talking about threading the hole and building a stop at the Huret position ? I think that's allowed in the rules. If it comes down to it, someone can still mount a Simplex or a Shimano Crane rear derailleur on the hanger in the future. Cutting it off completely is ill advised.

Does the Huret have the positioning bars in the body? If so there are a number of plates that can position the derailleur body in the correct way. I have found a number of the them on the inter-web. Smiles, MH

I don't think the slight mod needed counts as drewing. It doesn't prevent a future owner from using a Simplex mech. Doesn't harm the function one iota.
Tap the hole M10 and file the bottom edge only the amount necessary to make a stop for the Jubilee.

Who's even going to know? It'll be our little secret.

The Jubilee was produced in at least two versions, one for the Huret for Huret dropout or Huret “claw”.
‘the image in the original post appears to me as for a Huret for Huret form factor.
a Simplex can be modified, will require modification, the Huret is essentially a double stop design, one leading and one trailing. Reference one before you attack.
probably will require tapping too, 10x1.
there are various bolts for the derailleur, one used a backside fastener Inside! The pivot bolt, expanding the slotted threaded end.
Or if long enough Huret used a jam nut to control the “slop”.

Thanks all. Now to decide which frameset.

According to Disraeli Gears there was also a model made to fit Campag hangers the first couple years of production but very rare and pricey.

I have a 74 Motobecane Grand Jubile f&f with Huret dropout. Frame swap?

It depends on which Simplex dropout you have. Ref. 4130/4131 dropouts are unthreaded and have no stops to limit how the derailleur can pivot on the mounting bolt, so you'd need to tap the mounting hole (10mm x 1mm) for the Huret mounting bolt, and file stops into the tab, depending on which mounting type (Campagnolo-type or Huret-type) Jubilee you have. If you have the ref. 4266/4267 dropouts, you should be good to go, assuming your Jubilee is configured for the Campagnolo-type dropout.

Thought this Australian blog have a good article on the Huret mounting system. Got interested in the jubilee, and got two for campag mounts off eBay a long while back. They shift exceptionally well.

Mine are 60-62cm.

A little too big for me. My Moto is 58cm C-T.

I naturally assumed there was a size differnece, it seems there always is.

The derailleur and other pieces arrived and the derailleur is actually in pretty nice shape, better than it looks in the pictures. It deserves to be on something decent looking.

Taking the easy way out, I have a '76 Raleigh Super Course frameset I bought with the intentions of repainting with a '71 Raleigh paint color. Worksop built, Reynolds 531 main triangle, good chrome, no RD hanger and I have a Huret RD claw.

At least some of the 25” 1976 Super Course frames had forged Huret dropouts. Maybe not all, but some, like mine, did, so keep your eyes peeled.

Oddly, mine came with the “Italienne” version Jubilee RD that fits campy dropouts, so it needed an adapter washer to fit the Huret dropout.

My '76 is 25" but it has stamped dropouts with no hanger.

Trying to understand the various versions of the Jubilee RD always makes my head hurt, but I found this
write-up that is pretty easy to understand:
https://note.com/aki233/n/n1248c58d9177
It's in Japanese, but using Google Translate makes it quite readable.
I pulled out my 4 Jubilees and the aftermarket adaptor kit from my stash, and think I now get the general drift.
I think the aftermarket adapter kit is a reproduction of Huret part # 2333, which came with some later versions
of the Jubilee RD to make them fit a Campagnolo dropout and add B screw function.
There are NOS Huret part # 2364 bits for sale on the auction site by seller Idealvelo. PM me and I'll send you the link.
These look like they could be modified to look and function like part # 2333.
Also found and purchased a Huret rear dropout.
At some point in the future, I'll make 3D models of the Huret dropout, a Campagnolo dropout, and the adapter kit to
illustrate how these all work.
I don't know how a Simplex dropout differs from a Campagnolo dropout, so all of the above doesn't directly answer the
question, but hopefully sheds some light...

The Simplex hanger has an unthreaded 9mm hole with no B screw stops on the outside. It has enough material to file in stops and it can be tapped out to the10mm thread used by most rear deraillers. I could easily do that to either the Peugeot or Gitane but even though neither one is in great shape cosmetically I have a possibly illogical aversion to altering them. I had no qualms about having a Campy style hanger brazed on to my '73 Raleigh International because someone had already hacked off it's Huret hanger so the "damage" was already done. Which was too bad because it has pretty decent original paint but it was easy to repaint the new hanger and blend the paint and the shop that did the work made it look factory original. BUT, my Super Course has no hanger and I have the (hopefully correct) Huret claw mount.
