    Lo All,
    I was wondering if anyone might be able to set me straight.
    Are 9spd Dura-Ace/Ultegra casettes compatible with Tiagra? They are all 9spd systems but are the cassette sizes different or will they all work grand?

    Thanks in advance

    Tiagra derauilers or shifters?

    FWIW i run Tiagra STI's with my Ultegra casettes and rear derauiler on my CX bikes. Works fine. I think the pull ratio is the same but don't quote me if its wrong.

    My cross bike (badly neglected this year) has ultegra levers, 105/ultegra mechs and a tiagra block and they work fine.

    It will work fine. I did something similar for a bike I was working on, not a problem. The cassette spacing is standard and will work with all Shimano 9 speed setups. Cable pull's etc.. should not be a problem either, as I have also put Tiagra 9 speed shifters onto a Dura Ace 9 speed setup and it was perfect.

    Yep, I use Dura-ace 9 speed levers and ultegra chain+cassette plus an ultegra front derailaur, without any problems:)
    I find the ultegra cassette runs more smoothly that dura-ace, and seems to last much longer as well:D
    Plus the 9speed chains and cassettes, are far more durable than the 10speed stuff:)

    Happy Cycling:)
