  1. Hi All,

    After a few years with my bike gathering cobwebs, I have dragged it out, and
    need some assistance with adjusting the front deraiullure.

    my bike is a Specialized Rockhopper (2000?) with Shimano STX RC front
    derailluer. My problem is: I cant get into the front top gear. The
    Indicator on the handlebars says there is another gear there, but the
    selector is slack with very small movement left. If I didn't know better,
    I'd say the index mechanism only thinks there are 2 gears.

    I've tried resetting the derailluer height and lower limit again, but can't
    progress unless I can get the chain onto the top gear.

    Your words of wisdom or a link to a guide somewhere in the big bad intraweb
    would be much appreciated.

    thanks
    Al

    It's probably not an adjustment, but rather the spring not catching in the
    shift lever. That happens more often than not in bikes that have been
    sitting around for a while. Try flushing it out. We use PowerLube (available
    at finer auto parts stores everywhere), which I feel works quite a bit
    better than WD40, but there's no harm in trying WD40 to see what happens
    (you can always spray PowerLube back into it later).

    Ditto. I have an ancient set of XTR shifters (M900 series) that stopped
    working exactly as described. Two years after flushing them out with
    light spray oil, they still work fine. I used them plenty on today's
    ride- upper 30's and raining. Brrr.

  4. Jeff, Mike,

    Thanks for the advise - I'll give it a go this afternoon when I get back
    from my ride.

    FYI - here in Australia it's upper thirties as well - in the other scale....
    🙂 Not so Brrrrrr

  5. Thanks Guys, worked well : 5 mins after applying WD40 to the shifters,
    getting 8 out of 10 changes.

    Please do not top post. I fixed it for you.

    Now that your shifter is working, it is time to get the
    WD-40 out of their before it gets gummed up. Put in a
    good penetrating lubricant such as LPS-2.
