    Here is the problem and details:

    I have a new 9 speed Campagnolo veloce triple rear derailluer, new
    sachs 9 speed chain (with about 200 miles on it), new cables and
    housing. Campagnolo 12 -23 9 speed cassette. The 98 Record ergo lever
    has been previously rebuilt with new springs and new style 9 speed
    shifter cog.

    I can't get my derailluer to shift smoothly out of the 12t cog to the
    13t cog.

    I have adjusted the set screw, and the cable tension.

    When I increase the cable tension enough to allow the shift to occur,
    the downshifting does not work well in the other cogs. when I decrease
    the the tension so that shifting is smooth in all the other cogs the
    chain does not want to upshift from the 12t to the 13t cog.

    This is most noticeable when in the 52t front chain ring and not the
    42t or 30t on the triple crank.

    Please help !!! I have a long bike trip next week.

    Some things to check. It sounds like the inner wire friction is such that after
    adjusting the rear der to shift to the 13, it is 'too high' to let it back
    down. Check for smooth inner wire/housing action and also that the under BB
    guide is not casung any friction.

    Also that the inner wire is underneath the rear der fixing bolt, under the
    plate, not thru it.

    Ya didn't need the 'new post '98' shift disc, BTW-

    I have a question regarding under BB friction. I see on quite a few
    bikes that don't accept that little plastic/nylon guide they put some
    sort of plastic over the cable itself. Is this just heat shrink, or
    some sort of special slick cable cover??

    Should be a nylon guide identical to the material in V-brake noodles. Heat
    shrink would adhere to the cable itself, when in fact we want the cable to
    slide smoothly relative to the cable cover.

    The PTFE liner used inside brake casings is available bulk
    (per foot) at your LBS.

    You can use teflon lining over the inner wires but I recommend just drilling a
    hole, tapping it and installing a plastic under BB guide, on any frameset.

    Well, you can go to any LBS, buy a noodle and take the liner out, and affix
    it to the BB shell somehow. The LBS probably won't sell the liner
    individually because the noodle is useless without the liner.

    Most LBS which service bicycles have that sort of PTFE liner
    in bulk. It's used between cable stops on some MTB brake and
    gear wires.

    Yes... we have some too, but it's usually easier to find a noodle. It's
    usually used for top-tube-routed rear canti metal guides that wrap around
    the seat tube, no?
