Derailleur hanger with two "tabs" - which derailleurs fit??

[chkamb]

Hey folks
I am building my mid-80ies (?) rando and realised that my derailleur hanger is different compared to the average:

As you can see, it has two "tabs" (or b-screw tabs). Derailleurs with angle adjust screws do not fit, also pre-SIS mechs like a RD-6207 (which I tried) without the screw but with a sickle-shaped part (?)..

So, what mechs will fit? I am in a dead end street..

About the frame: mid-80ies (?) rando frame with very narrow cantilevers (55mm), no manufacturer labels but Columbus Cromor tubing labels, no marks on the dropouts..

Mid 80's frame, then before Shimano got such a hold on the market and more likely to have had something like Campag on it so pretty much anything else from that era should fit.

Campag brought the current standard style iirc.

Try Huret.


(I don't know to much a out road or pre 90s bikes unfortunately)

Hi, thanks for the reply. The Huret hanger looks slightly different..
I tried the early SH NS Touring http://www.disraeligears.co.uk/Site/Sac ... lleur.html which does NOT fit. The short cage Aris New Success DOES fit (http://velobase.com/ViewComponent.aspx? ... p;Enum=108).

I did think of Huret or Simplex but I think it's intended to take a few different ones, looking at it any Campag from that period and earlier would fit. I had a similar looking one on a French made frame and that had a Campag Triomphe on it.

You'll all know better than me.

At first I just thought it was a semi-vertical droput with some neat styling and the notch is worn down/point taken of a bit.
I'm a early 90s MTB person and had plenty with the small tidy steel framed notch is worn down like that where a b tension screw would not engage (unless you bend the screw a bit to give it purchase).

OK, Google helps.

It is a Shimano UF Dura Ace semi-verical dropout. So nothing special, it has been chromed. But: why do my average derailleurs do not fit???

Edit: there have been even in the 70ies such dropouts, the Shimano NB-120: https://www.bikeforums.net/classic-vint ... 975-a.html

Yes I've seen that sort of wear before but this one didn't look worn. You're probably closer with Huret though as a lot of the French makers did their own thing in the 60's and 70's, as you say the Campag standard ultimately ended up the one that's been followed by everyone now but I thought that got sorted out way before the mid 80's.

The similar one I had was a horizontal dropout and earlier than this and may well not have had a Campag mech on it when new but it fitted fine so I expect anything without a b screw tensioner setup will fit

I'd have put money on it being French, better not do the lottery today then. Well you live and learn
