    Installing Shifter Housing

    It has been a very long time since I replaced the housing in my road bike. My question is about the loop that goes to the rear derailleur. The frame braze-on will only fit a 4mm housing if I remove the plastic from that end. Is there a housing that is intended for that purpose?

    Thanks

    Old steel bike? If so there are 'step ferrules' that work for that. Maybe post a photo just so we can be sure. There is no special housing that is smaller than 4mm.

    Yes it is an old steel frame. I will take a photo. Where do I get the step ferrules?

    Both Campy and Shimano used to supply them w/ cable/housing kits but no longer do. You can get em here:

    Or if you've got a LBS that's been around for a while they'll probably give you one.

    Something that I don't understand. I checked out your link. The inside diameter is 4mm and the outside diameter is 6mm. How would that solve the problem?

    Yeah, the little nose goes into the stop on your frame. The I.D. of the ferrule is 4mm to fit the housing. You don't need to pay any attention to the O.D. for this particular spot but that is standard as well. Both shift and brake housing ferrules have an O.D. of about 5.75mm +/- so they'll fit in any frame. Or shifter that uses ferrules...or brake that uses them...or derailleur that uses them.

    Slightly confusing terminology. The larger section is 6mm OD; the smaller section is 4mm OD, which matches the INSIDE diameter of the stop on the frame.
    Have you ever been to Electric Ladyland?

    Thank you
    Can you please elaborate. How do I install the ferrule into the frame braze-on?

    Seriously? You just put the small end into the hole in the stop. From the rear of the frame. While the ferrule is installed on your derailleur housing.

    That looks like a Nuova Record derailleur.

    I believe you're right! One in that shape is probably worth a pretty penny now.

    Will I have a problem? I just measured the opening of the stop. It measured 3.96mm.

    No. As we've posted repeatedly shift housing is 4mm...you need a ferrule w/ an ID of 4.0mm. Not 5.0mm.

    Also here - Shimano part # Y6Z290030

    If it's a little tight, sand the small dia. end of the ferrule down slightly

    Question arises. What did you do with the old step ferrule that came with the old RD housing? I would have just used that after cleaning it.

    I would think that most any LBS would have many of those step ferrules in a drawer in their shop.
    Trying to cram the rest of my life into the rest of my life!

    That is a good question. I never used one. I had just forced the housing into the stop.

    Just saw some NOS NR rear ders on ebay for between $400-500. Used for as low as $50.00.

    no need for nos. these works of art are almost bullet proof. like vintage suntour, they are easily overhauled. new shimano wheels ($8) fit nicely and look the part. a little road rash can be polished fairly easily.

    vintage super record, on the other hand, might fetch up to $125 in the summer.

    Obviously not *necessary* but I guess there are guys out there that want it.
