    Converting dura ace 7700 to 11 speed?

    Hi,

    Does anyone know if a ultegra 6800 freehub body will bolt to an old dura ace 7700 (9 speed) hub? I'd love to not have to lace up or buy a new wheel.

    Thank you!

    When you make the jump to 11-speed on Shimano, you make the jump to new wheels.

    Unless you have some Mavic wheels....Otherwise, you are S.O.L.

    Buying parts to hang on your bike is always easier than getting fit.

    If you feel wimpy and weak, get out and train more, ya wee lassie!

    And that's why I went Campy when I converted my bikes over to 11-speed. Shimano didn't have to do this. Campy didn't when they went from 10-speed to 11-speed.

    Except you will need to change hubs if you go to Campy 12-speed...

    I skipped 10-speed and will probably do the same with 12-speed. I just sold 7 sets of 8/9/10 Shimano compatible wheels that were completely useless to me.

    The reason that it won't work is that your 7700 hub is made to work with an "old school" standard diameter axle, and the 6800 hub use the new oversized stepped axle...
    BUT.
    I just remembered that the first generation shimano 105 11 speed hub uses the "old school" type axle. There is a possibility that the 105 11 speed freehub MIGHT fit on a 7700 hub......If it does, you'll still have a problem. Since the freehub is longer, you'll have to use different spacers to move the hub over a few mm to the left......The wheel will have to be redished to center it in the rear triangle. With all of this work to possible make it "MIGHT" work, it would be easier to just buy a new wheel.....
    If your opinion differs from mine, ..........Too bad.
