    Yet another compatibility question...

    I got lost in google land trying to figure this out. Will this work:

    - 11 speed SRAM shifter
    - 11 speed 11-40 cassette
    - 11 speed chain
    - 10 speed SRAM xo RD

    Thanks!!

    I know the RD will clear up to 42t cog. Can't guarantee you will not any problem with the 11s shifter, but I think you will be alright.

    Yes, I know it will clear at least the 40 - good to know it will go to 42. Thanks man.

    My confusion is that Iíve used this 10 speed xo RD on my CX with an 11 speed drivetrain and it worked (road shifter)!

    I was told this isnít compatible from a friend with an 11 speed mtn shifter.

    Looks like your friend is correct. SRAM 10spd mtn and 11spd road both use "Exact Actuation" (1.3 shift ratio/3.1 cable pull), whereas SRAM 11spd mtb uses "X-actuation" (1.12 shift ratio/3.5 cable pull). How close that translates into real life, I don't know. Maybe others have tried and would know for sure.

    Ah crap. Thanks for the info. It looks like Iíll need a new 11 speed RD, but the worst part will be telling my buddy he was right!

    Thanks again.

    There's always Shimano.

    OK, but for real I have to look this stuff up, too. It's not something I just knew off the top of my head. Art's website is a bit wonky since they redid it, but all the info is here...except the Shimano 10/11spd mix n match actually works. Dunno if they updated the article to reflect that. Either way, it's a good resource.

    Ah perfect! Great resource. I see why my road example worked and this doesnít. Ha, now I gotta find a use for this 10 speed xo rd!
