  1. I've had two shimano cable breaks in the
    last year. One had 12,000 miles, the
    other one 6000 miles. They both broke
    at the head, in the shifter, and didn't
    completely break, only partially, which
    drives you nuts, because you think it's
    some gatorade goop in the bottom
    bracket, or the adjustment which it
    rarely is for such a big malfunctioning
    rd, where it shifts on it's own.
    Weren't there some bad shimano cables
    out there, or is this how their life
    typically ends?

    If you are easily offended do not read
    any further.

    I learned this out of desperation on one
    of my boonie rides in the desert.
    Typically when the rd starts to act up,
    it's usually the gatorade goop, that
    dries under where the bottom bracket,
    making the cable stick. I only had
    bottles full of gatorade, no water, and
    no source of water for miles around. So
    I scratched my head and came up with a
    solution..... but I have pee. Turn the
    bike upside down, now this takes extreme
    control, it doesn't take much pee, to
    melt that sugar away, and then stop, or
    point the pisser away from the bike and
    complete the job. Obviously you don't
    want your bike covered in [censored]. This is
    only recommended for a man, not a woman
    to do. Serious injury could occur to a
    woman. Of course this could all be
    avoided, if they made a bottle that
    didn't leak. In the desert, you are
    limited to Polar bottles because of the
    heat, and they all seem to leak after a
    while, even the new design. Don't know
    why, but they do.

    My rear shifter cable will break almost like clockwork every 4800km or
    so. I've just got in the habit of replacing the inner every 3200km and
    the outer every 6400km. The front cable lasts about 50% longer.

  3. removing cables, cleaning, relubing the system at reasonable scheduled
    periodic intervals
    keeping a log.
    if you find a flattend cable area, like that's it.
    you go in

    Wait right there.... you put 12,000 miles on a cable and you need to
    discuss it's "short life"?

    entirely typical. replace preemptively based on the above data and
    you'll never have a problem again. halve the expected mileage for
    cheapo no-name cable.

    and yet they last longer than cables in campy shifters. or is this
    where we're all supposed to retro-grumble about friction shifters and 5
    speeds?

    I agree. I squirt WD40 on the cable guide and cables occasionally.
    Works better than water. Spray furniture wax works ok too.

    I wouldn't view a sticking cable as something that requires emergency
    repair.

    In my opinion, my Ergo stuff wins the cable wear award.

    --------------
    It depends, if it's really sticking you
    can break the innards of an STI shifter
    like I did once. By being lazy, I paid
    $100 for a new shifter.

    Broke my shifter too...twice🙁
    Are there any indexed shifters made with decent steel innards?

    Friction wins again!

    Indexed DT levers and indexed barends do not craok cables, either, IME.

    My recollection was that the OP had STI. Or should I have said, "your
    shifters have short cable life, but it could be worse"?

    We could point out that the non-brifter alternatives (indexed DT
    shifters, indexed barends, etc.,) do not have this problem.

    Perhaps, but the OP has STI.....

    I wonder if that's because we shift more often with STI levers? The radius
    of the bend should be the same, shouldn't it? Or are you thinking the
    tighter curves in the cable run (where it follows the curve of the
    handlebar) create enough increased friction to cause the cables to break
    more readily?

    That might be part of it. Some riders using brifters do shift more
    than I would have ever imagined (click!click!click!click!).

    The cable pull is the same. Of course, there are far fewer 9 or 10sp
    indexed DT or barends in service v. 9/10sp brifters. Most of my "data"
    is based on brifters v. 7/8sp. Maybe that's a factor(?).

    Or are you thinking the

    My guess is that it's the increased shifting in concert with something
    peculiar to the brifter inards.
