What's the issue with Simplex drops, DR's?
 

This is a great, but infectious forum. Browsing this board has piqued some interest in European bikes, but my knowledge of them is worse than pathetic. (Ever since the 70's, all my bikes have been Asian.) I keep seeing offhand comments to the effect that Simplex dérailleurs are required for certain dropouts on Peugeots and maybe some others. Am I reading that correctly? And if so, what's the reason for that?

You need at least one French bike.

I ran a SunTour Cyclone II rear derailleur on my 1980 PKN-10E for several years, before converting back to the original Peugeot-labeled Simplex. Both hung just fine :)

Everyone does!

We are diabolical :) .

That's an English expression, by the way. My cousins in Brum used to say that all the time :p .

Who are you, and what have you done with our cat?

Thanks, everyone. Y'know, I actually read that article just a couple of days ago, but completely missed (or forgot) that section about the derailer hanger. Some days, my "senior moments" seem to be turning into hours.

That's not the word my Scots, Irish, and Welsh forebearers used........:D

No, not really. Though I have a couple, I typically HATE French bikes. Nothing ever seems to work quite right, even with a lot of fiddling. But maybe its just me.

its just you ;) i have 9 french bikes love em all .some with simplex some without . i like the simplex stuff

Just this weekend I finished re-habing a very small framed Ficelle for my daughter to ride this season. This is the most French bike I've ever seen:Vitus tubes, Nervex lugs, TA cranks and BB, Huret drivetrain, Mafrac brakes, Lytard pedals, ect. Put it on the trainner, adjusted the DR limits, and it ran like a champ. She's grinding away on it now.

my french bike had its derailleur hanger cut off in another life

PX-10 --> PX-1

So, it looks like the previous owner of my PX-10 went ahead and tapped out the hanger to accommodate a larger thread (for a shimano derailleur)

I am trying to get the bike back to an "all French" status, and the simplex derailleur i got for it is too small for the threads.

basically, I'm boned, right? unless i want to use the adaptor claw.... which wont attach permanently :notamused:

sigh.

The one French bike I have works marvelously :)

I love the Simplex Super LJ derailleur on my PH12. It's silky smooth.

I'm deep into the French stuff as you can see on my bike. But like John E, I had a Suntour Cyclone II RD on this bike earlier in it's life.....then a Suntour Superbe from my brother (who I traded the Cyclone with) after that. Also had A Nouvo Record RD before these Suntours and the bike did come with a Simplex SX610 The Suntours shifted the best with the Simplex coming in a close second because of it's similar slanted parallelogram design, then the Campy NR. The present mounted Mavic 810 RD/FD was a late aquisition I got in the 90's. I still have those other derailleurs that might perform better than the Mavic, but this Mavic 810 set just looks to be the most correct system to keep on the bike for good!
