Are you sure that front derailer is a Super LJ? It looks like steel and I've never seen a super LJ with a housing stop.

Seeing a Super LJ Aerodynamic rear derailer and a dork disk on the same bike made me throw up a little bit in my mouth.

To the rescue! This pic angle might help by stimulating a bout of projectile vomiting to aid you in getting over whatever you are afflicted with. :rolleyes:

Thanks again-best I can tell-it's been shaved/Yes? Just got an 80's torpado with a sx410 on it-tho I havent taken it apart yet-all is not lost:) BTW I voted suntour/and your bike is a beaut!

No, I don't see. An LJ is not a Super LJ. A Super LJ will be all aluminum. Your LJ has an aluminum clamp and the rest is steel. I have the same derailer on two bikes.

No, not shaved. Far as I can tell, the dropouts are "standard" with the Simplex being the oddballs. My RD does not attach like typical Simplex, but is designed for a more practical dropout - hope that makes sense. That's my read on it anyway.

Apparently the SLJ was produced in several versions, all categorized as the Super LJ. ;)

What a bunch of bunk. Nothing wrong with the Simplex derailleur. They work fine. They don't work well with wide range freewheels which most bikes were equipped with back in the day. With a 14-21 freewheel this 40 year old Simplex works nice and crisp. The shift levers suck. Those I don't hesitate to replace.

What's your point? Your FD is not among those in the link. You have an SJA 102. It's a decent midrange derailer, but it's not a Super LJ. LJ is simply Lucien Juy's initials and they appear on most Simplex products. Super LJ is reserved for their top of the line.

Thanks for the clarification. Hard to see that section of photo. Took my simp off today and lo and behold: a reg threaded dropout! Hoooooray! So same sitch as yours. Already a suntour Lapree on there for the front ;)
