A cautionary tale for old derailleurs
It is a gooood idea to check the limit screws and add a coat of loctite if they are at all loose. I am off today to the bike shop to replace the nine rear drive side spokes that sheared when the chain dropped.

If only they made a piece of plastic or something to help prevent this....

You can post pics of your bikes there and chide BF members for not having the smarts to run them.

The new/old Sachs freewheel I just installed on my Motobecane Grand Record came complete with one!

I visited a closing bike shop and asked about their dork disks. They gave me a box of various sizes that they removed over the years, so now all my bikes have them.

Some of them are beautiful. I have a few bikes that proudly wear their dork discs.

The limit screws have springs to keep them in place. If that's not working, try different screws. Then use loctite blue.
If my chain drops from the big rear cog, physics pulls it down to my next smaller cog, not toward the spokes.
For all my rebuilds, the dork disk always goes with the reflectors, steel components, kickstands, and turkey levers: straight in the trash.

Oh, that BLOOOWWS. I've never run a dork disc but I've also never had that happen. With that said, I do have purple that I usually use on small, fiddley screws.

I use dork discs. And I use helmets.

Ooh. That's a real clunker.

For the bored, take a drink every time RJ says "here."
Aubergine, if you have a Campy-style hanger, best to use almost any Suntour mech in place of that Eco.

Seriously, the DuoPars work very very well, but I acknowledge they need attention. Which is why it really is on me that I did not notice the limit screws were loose enough to unscrew. And @SurferRosa, the derailleur is on a 1973 Motobécane Jubile with Huret dropouts, so it fits perfectly with the age and character of the bike.
I have another DuoPar on my Old Peugeot #1, an AO8 from 1974 or thereabouts. It has been a standout. So I am confident that these work well when cared for.

I take that back. Don't do that. I had to count 'em. 86 times. 86 drinks will kill a man. No matter how clunky your derailleur, you shouldn't have to die for it.
I think he says "there" about half as many times, but I didn't count.

@SurferRosa Nothing wrong with Duopars. Not many mechs can compare to the chain wrap capacity of an Eco or Titane. Nor is the Eco (steel cage version) even that heavy for a nice long cage touring derailleur.
Also, if you really do throw all steel components in the trash, there would be quite a few Campy and Suntour mechs in the trash as well. Read up on Disraeli Gears and you'll see the nicer rear mechs didn't start going to alloy bodies until the 60s/70s. Even then and still today, rear and front mech cages are still made from steel as it is an application that requires it. No use making blanket statements throwing things in the trash.

Yes and no. I haven't come across that many campy steel derailleurs. Three, I guess. But you're right. Unless they're campy or suntour, the steel bits go in the trash.

Hmph! I am offended. I love my DuoPars!! They are better than even the best Suntour friction derailleurs. So there, Nyah Nyah.
Seriously, the DuoPars work very very well, but I acknowledge they need attention. Which is why it really is on me that I did not notice the limit screws were loose enough to unscrew. And @SurferRosa, the derailleur is on a 1973 Motobécane Jubile with Huret dropouts, so it fits perfectly with the age and character of the bike.

YMMV
(OTOH, it's been a while since I've even been in the lowest sprocket, so I wouldn't be risking much)

@Aubergine, sorry to hear about your limit screw up. I nearly did the same thing once. Only caught it as I checked the shifting in the stand before I set out. Hope you get things squared away quickly.

I am sorry for your spoke shearing incident, early in my bike fiddling days I "adjusted" my RD to accommodate a bigger Cassette (yes before I went full on C&V) and ended up trashing the derailleur hanger which fortunately was replaceable. I have to say your Nyah Nyah retort made me laugh out loud, just glad I hadn't taken a drink or it would have been spit take city.

Ha. Well, I figure that arguing over C&V equipment shouldn’t become too serious. :-) I like Suntour dérailleurs a lot as well — I have a VGT on Old Peugeot #2 — so I actually would have been content to use one on the Motobécane if it had had Campagnolo standard dropouts.

to add another layer to your game, or if you're just bored, use youtube's speed up/slow down feature to put rj at half speed and he sounds just as drunk as you're going to be playing the "here" or "there" game
