    Yes. Should be no problems whatsoever. Cassette is the same width as 10 speed if you were not sure about that either.

    I believe this is incorrect hence why new 11 spd hubs have a different cassette body and run extra spacers when using 10 spd cassettes.


    As far as your crankset goes, yes should not be a problem. I know Praxis works makes a great chainring set that works with that crank and will work on 9/10/11 spd chains.

    For what it is worth I am using a FC9000 11speed crank on a otherwise 10speed 6700 system including the 10sp chain with 0 issues. Common sense would tell me that if my setup works then a 10sp crank should be fine with a 11sp chain.

    From what I've learned over the last few years, there's a lot of room relatively with front chain rings. I wouldn't try and run a 10/11 spd chain on a 7 spd front chainring but I think you can safely move around between 10 & 11. I even know a mechanic who swears by running Campy 11 spd chains on 10 spd Shimano drive trains.

    Augh, I had things the other way around in my mind. 11 speed hub is backwards compatible with 10 speed cassette with said spacers.

    Yup! Was talking to some Shimano techs and they said "We've learned our lessons about making things non-backwards compatible." Currently running 11spd C24's as well as 11 spd R45's and they both run flawlessly with the spacers.
