    A bit of fine tuning required (cable may have stretched) ?

    Have you always been 9 speed?

    Some 8 speed chains are too thick (and even some 9 speeds) and can catch slightly.

    Have you changed anything else other than the shifters and was it all working before?

    Pat...

    i have just had kind of the same thing

    i changed the following.

    front chain set
    chain
    rear Mech

    and mine kept jumping off the bottom rear ring...

    after talking to a few people they have said to change the rear cassette as I had changed everything else....

    this may help?

    yes all was fine before i changed them from sti shifters
    new cables used dura ace ones
    its not jumping cos of the cassette etc its definitely the shifters as they work fine in friction mode its just sis mode that wont work

    You said you had 9-speed previously? What 9-speed, exactly?

    AFAIK the Shimano 105, Ultegra and Dura-Ace kit has a certain chain & sprocket width which is narrower than Sora or Tiagra. If you're trying to mate a Dura-Ace shifter with a 9-speed Sora or Tiagra rear then it won't shift properly. It will be trying to shift by a smaller amount than you need and it will slip.

    If it works in friction mode but not SIS then this suggests that this is the problem.

    Or, as CH suggests... go and ask a professional!

    have taken it to a bike shop, they also said it seems like something was wrong with the shifter
    it clicks and shifts into place on the top and bottom gears but doesnt click or stay in the middle three
    maybe it is just that i need a new cassette then to match it up.
    friction mode will have to do for now!!!
    cheers for all advice tho

    at the time i was setting mine up...

    i had

    Dura ace bar end shifters
    campag fron chainset
    campag rear mech
    campag rear mech
    ambrisio chain

    changing the rear mech to shimano 105 and it was cured, apparently its something to do with the aount of cable the shifters pull through, its like .5mm where as campag needs a different amount.

    as i said once I changed the rear mech to shimano aswell it was fine
