I have a worn out Simplex RD on this bike. I have few decent rd's but none of them fit the dropout hanger. Another BF member said that this has Zeus drop outs. I can't post better pics right now, but I was wondering if anyone knew if these would be French threads and if a Huret rd might fit?

Thanks in advance!!!

Thumpic, bad link on the photo.

You can try this one if you twist my arm hard enough.

Do yourself a favor:

Thanks PastorBob!!! That's very generous!! Sorry my link is bad; I'll fix it when I get home.

However my rd screws in to the drop out w/o a hanger. I'll be sure to post a pic of the drop out.

BBM...thanks for the suggestion.

I was thinking Huret because of the supposed French threading. Do either of you know if Raleigh used that threading on the bikes with Simplex components?

Thumpic. There was a thread a while ago concerning Huret on Simplex dropouts. You might check the archives. No expert myself, but I don't think it'll fit without an adapter of sort or maybe not even with that. I think you can remove that hanger and use the old bolt from yours and mount a new one.

Zeus drop outs?...on a Raleigh ?........ is this the April Fool's part???

If it's the forged Simplex DO (as on a PX10), you would have to drew it to accept a Campy style DR.
Simplex DO's were made to take Simplex DRs, and you really don't want to grind it.

Someone did that to one of the Project bikes in my queue, and it is devalued as a consequence

OOps. what I meant was, use PastorBob's replacement by removing the hanger off that derailleur and using your attachment bolt. DON'T grind the dropout hanger!

this link should work.......and here are pics of the issue...

No, in the early 70s Raleigh used Zeus dropouts on the Super Course and Grand Sport frames.

A Simplex mech should work fine on a Zeus dropout -- it doesn't use the threads in the dropout but is held in place by the Allen bolt threaded in from the back.

This statement is not totally correct. There were later Simplex forged DO that were threaded to also work with other derailleurs. I have one on my Lejeune tandem which is using a Shimano 600 rear derailleur. You are correct that you do not want to grind it.

So these are not bizarre French threads?? Modern common brands can be had that fit??

WOOHOO!!! I searched a little harder and found an old Mountech rd....before you start; depending on what you read this can self destruct at any moment.......but I'll give it a whirl.......

I think the bold italic part of the original post answers that question.

update.....found a Raleigh branded RD in another pileo'stuff and it works flawlessly.............
