    only works if you know what your getting into and can do all of the work to it yourself.

    not sure what help you want, I only know of one built in recent years, and it was mostly for show. I really doubt you are going to be happy with one on a triple, any pushrod FD has limited range. And they usually stink anyway

    I don`t think those have been made commercially for... 40 years? 50? Being that I`ve never had the opportunity to use one, I can only suspect that Unterhausen is right about them not working very well, and probably even less on a triple.
    On the other hand, they sure look cool! Do you plan to build one? If you do, please post how you go about it. Personally, I`d love to have one.

    unterhausen, do you know of any photos of that front derailleur set up?

    rodar y rodar, your correct a lever type front derailleur hasnt been done in bicycle racing in way many years.

    i have some old photos i would have to dig up if anyone wants to see one. the whole assembly is brazed to the seat tube with a thumb lever on a metal rod the action looks push and pull. what im looking for is more info on these without starting from scratch.

    Hone your skills on that one, then you`ll be ready to tackle a rod shifter for the rear.

    A few years ago, I saw a killer video of a guy shifting Cambiocorsa and Roubaix systems while riding. Very well done and a lot of fun to watch. Now I can`t find it- does anybody have a link for it?

    pdf warning: link

    You may be able to find more pictures from NAHBS
    You can see more period examples if you search for French bikes on ebay or on flickr

    I have an ambition to make a cambio corsa bike, but the dropouts are hard to find. I have thought about trying to build a broach to make them, but that would be a little tricky

    ^^Don`t you think they could be just filed in? I think the tough part would be the pinion on the axle.

    there are hubs and other parts out there to be found, the frame parts are not so easy to find. I guess you could lay them out carefully and file them, I'm not that obsessive. Waterjet might work though

    It seems to be "off the air". I found the rbr post where I had originally gotten that link- it was on wooljersey, which disappeared. No more WJ website, or is it just my computer?

    nice good input info on lever derailleurs this should be better documented in the bicycling community. i look at it as an option i will worry about the efficiency later.

    I am building a 30's style bike in the near future. I am thinking about using some home-made derailleur system also. 'should be fun!
