    Different ferrules for different cable stops?

    Hi all,

    I have just finished rebuilding my 1994 Marinoni Special, and I'm having some trouble with the rear derailleur cable housing. The cable-stop on the chain stay is not the modern type, which accepts a standard ferrule. Rather, it is a small, spherical braze-on with a hole drilled through; a hole exactly the diameter of the cable housing I am using. If I don't use a ferrule on the end of the housing, it slips through when I try to shift - no good. On the other hand, modern ferrules sit against the braze-on and create an abrupt and problematic change of direction in the cable.

    I am sure that there was a specific ferrule made for this application back in the day, and I just need to find one. What is it called? What does it look like? Are they still available from retailers, or do I need to scrounge in the misc. parts bin at the local bike co-op/used bike centre?

    Thanks for you help!
    Neil

    The hole goes all the way through the spherical piece? A photo would help.

    There are "step" ferrules that have a reduced diameter "nose" after the cylindrical section the housing sits in. One of thse may be suitable.

    I have the same spherical ball braze-on on my '91 Tommasini. You may need to aquire an old NOS derailleur cable, as the ferrul on it would be the one you want. The one on mine is roughly a half inch long and rests up against the back side of the braze-on.

    Thanks, this is a good thought. If the ferrule is something I can remove and transfer to the new cable housing, then I don't even need NOS, I could take POS grade!

    Someone at the bike co-op suggested using the barrel adjuster from an old derailleur to fill the same role, so if I can't find one of these 'step ferrules' from an old one, I might try that.

    Cheers,
    Neil
