    Dura Ace 7900 Hubs and 9 speed cassette?

    I know that 7800 hubs are not compatible with 9 speed cassettes but can anyone confirm if 7900 hubs are 9 speed compatible? I've looked around and found some conflicting info.

    I haven't done it personally but everything I read indicates that they are compatible. Who says they aren't.

    Some retailer on eBay, has it as 8 and 10 speed compatible, but it could be a typo I guess, thanks.

    they are.

    the only hubs from shimano that are 10sp specific are FH-7800 and FH-7801.
    there were also a some ultegra and DA wheels that were 10sp specific, but they weren't sold as individual parts.
    FH-7850 and FH-7900 can be used with 8/9/10sp cassettes.
    Food for thought: if you aren't dead by 2050, you and your entire family will be within a few years from starvation. Now that is a cruel gift to leave for your offspring. ;)
