    Hello,

    I've recently had some problems with my Dura-Ace SL-7700 shift-levers.

    Yesterday during a century, the rear derailler cable sheared off inside the shifter. Luckily, the
    support crew had a spare cable and helped me fix it. It was a [censored] getting the sheared off cable
    end out of the shifter. Since then, when ever I downshift (move to a larger rear cog), the cap of
    the shifter shifts latteraly, preventing the lever from returning to its proper position. I
    litterally had to move it back with my hand for the rest of the ride.

    This morning I took it apart again and sprayed WD-40 in there and worked with it, but I still have
    the same problem.

    Is there anything I can do myself? Or should I send them back to Shimano to have them waranteed?

    Thanks in advance,

    - Boyd S.

    If your DA STI shifters are less than 3 years old, I would have a good LBS take a look at them and
    if it appears they can't do anything, get them warrantied!

    Sounds like the very common small lever travels with the big lever probelm. If WD-40 didn't help,
    need a warranty...

    This is a warranty issue because the levers are less than 3 years old (~3 months actually) and don't
    work properly. I didn't abuse them. They are in perfect shape cosmetically.

    Can you tell me a more appropriate situation for having an item warranteed?

    Good luck,

    That's interesting. Campagnolo wouldn't warranty my one-season old Ergo levers that needed
    rebuilding. They said they consider it a "wear and tear" issue. It's great that they offer
    warranties and don't back them up.

    Are you sure they offer a warranty? I know Shimano warranties their products for 1 year and Dura-Ace
    and XTR stuff for 3 (against defects and abnormalities, of course). I don't know about Campy.

    Ok, how is the D/A shifter defective?

    Tough to really say w/o seeing the lever but I think perhaps his problem

    the broken cable may just be a coincidence.

    I agree that without seeing the lever itself that it MAY be a warranty issue. From the OP,
    IMO it isn't.

    Because a cable broke off inside the housing doesn't necessarily mean that the lever was defective.

    If its the cable's fault, suck it up. Your lever didn't do anything wrong. If its the lever's fault
    THEN I can see warranty-ing it, but I'm willing to bet that it was the cable...

    I have a friend who's right shifter went south after he broke a shifter cable inside of it. Some of
    the small pieces of wire found their way into places they shouldn't be.

    FYI, Shimano warranteed the levers; I got new ones via UPS today. So, they apparently thought they
    were defective. Otherwise, they wouldn't have replaced them.

    Interestingly, they sent me a different version. The ones I sent in were model ST-7700, while the
    ones they sent me were ST-
    7700c. The only differences I noticed were as follows:

    7701) There's a little piece of rubber between break lever and shifter lever to keep them from
    banging together on rough road surfaces.

    7702) There's a cap held down with a small screw that covers where the shifter cable goes into
    the lever.

    These differences only tend to confirm my suspicions that my previous set were an earlier, inferior
    model. If it ain't broke, they don't fix it.

    The only difference is that the "c" model is "flite-deck" compatable.

    That and you cannot put the 'blade', shift lever/brake lever assembly, onto the body of a non-flight
    deck shifter.

    I had exactly the same problem (except for the extraction issue) early this year. I suspect the
    cable was fraying inconspicuously over time and when it finally broke through, a strand of wire may
    have gotten caught in the shifter mechanism. After replacing the cable, the shifter did seem to work
    but got steadily worse to the point of total failure 3 weeks after the cable incident.

    I sent my right shifter in and Shimano warranteed it, returning a brand new shifter within 2 weeks.
