quirky gear hanger - how on earth??

edited June 2007 in Road general
Can anybody help me with ways in which I can fit a rear mech to this http://i2.photobucket.com/albums/y29/Boly/DSC00748.jpg gear hanger please. All my other bikes ( and any that I've seen), have had a cut out to take the adjusting anvil allowing the screw which raises the height of the jockey wheels to operate? I'd rather not hack the frame around if I can avoid it and I presume removing the anvil from the mech would allow it to unscrew. Someone suggested that I fit a detachable gear hanger from the dropout, but the original intergral one is cast at an angle making this almost impossible? I'm wondering whther only something like a benelux might fit. Any suggestions most welcome. I hope I've explained this clearly, having reread it I have my doubts....

    It's a Simplex drop-out and was made to work with Simplex derailleurs (Huret also had their own drop-out style whilst the rest of the world went with Campag as the default).

    That's a Simplex dropout, you can see "Simplex" stamped between the ends of the stays. I'm not 100% but I think Simplex rear mechs had a different arrangement compared with Campag, Simplex rear mechs had a strung top pivot and the angle of the main body varied according to the gear ratio used, whereas Campag ones had a fixed angle.

    You may also want to check that the threads on the mounting hole are able to take modern derailleurs bolt - most Simplex drop-outs were made without a thread - it could well be a funny French threaded job.

    Thanks Gavin/Tom. Do'h,I've been sitting looking at that Simplex stamp and not a single braincell fired! I imagine that's also why the braze ons for downtube shifters wont take any of my Suntour/Campag levers.I need a simplex oneª! If I cant track down a simplex rear mech and if the thread will take a "modern" derailler, is there a way in which I can fit it or am I condemned to trawl E Bay into my twilight years?

    You could always run it fixed [:D]

    Although they may think it sacrilegious and threaten to burn you at the stake for some of the heretical suggestions.....

    Try some of the retro bike forums or the CTC for advice.

    Think I'll try for some Simplex bits - maybe theres more on the French E Bay? Re your question Bagpuss, its that 53 Claud Butler New Allrounder - thats why I'm surprised that it has been made with Simplex drop outs/hanger etc? Thanks again to all for the info. NB I fell off a fixie in 1964 Gavin, I'm still recovering from the trauma - Not sure being cool and 58 is compatible ;)
    NB Just trawled the Vet/Vin bike forum - early 50's NOS Simplex circa œ1000 - maybe I'll attack the hanger with a dremel and fit a 105 after all!

    I damn well hope that it IS!

    I have a 1961/2 Delrin Simplex mech in good order (no badge) you can have for a fiver including post. Not sure about the thread issue. As Gavin says Huret used there own (bloody french) and the rest of the world went Campag.

    Thanks Dickie, yes please, thanks very much. I've e mailed you direct Bob

    I will have to dig it out which may take some time. It is yours for sure though, I got your mail.

    Hi Bob I've not forgotten you!
  • bolyboly Posts: 71
    No worries Dickie, I have a shedfull of partial rebuilds all requiring my urgent attention, theres barely time to sit in sun and drink beer. BTW - the hanger seems to have a standard British thread - seems a bit daft dont it? - if it's built to take Simplex rear mech with ( presumably ) a French thread??
  • DickieDickie Posts: 1,489
    Campag drop outs have a 10mm x 1mm thread if thats any help. Simple to check with a thread gauge and you can measure the core diameter with a vernier.
