    Which Shimano Front Derailleur?

    I am updating my Stumpjumper FSR Expert Carbon 29 2013, replacing all SRAM with Shimano (lets not get into a discussion which you prefer...)
    On the XT front derailleur on Shimano's website there are a few options:
    FD-M780 FD-M780-E
    FD-M781 FD-M781-D
    FD-M785 FD-M785-E2
    FD-M786 DD-M786-D

    Which one is the correct for my bike?

    Thankful for any insightful answer.

    You are going to need a S3 direct mount front derailleur. So the Shimano front derailleurs will not work.

    Either keep your existing Sram FD or pick up an X9 or X0 in the S3 model. They will work with the XT levers just fine.

    Is that specific to his frame? How annoying.

    My bike came with XT front to back so I won't ever change it but that's annoying if he's stuck with something he doesn't want because of his frame...

    Can't a Shimano E or E2 be used? I was under the impression they were interchangeable with S3.

    I've got a Jet9 RDO that is spec'd to run either, and i'm running shimano with no problems.

    Re: Which Shimano Front Derailleur?

    E2 from shimano but if you're using smaller front rings the 36/22 sram FD shifts better.
