    Will an 11 Speed GX Der. work with an 11-32t cassette?

    I'm building a gravel/adventure bike and currently am piecing together a drivetrain with some new parts and some I already have. I have a GX 11 speed shifter and an 11-32 11 speed cassette. Can I use a GX rear der. or does the GX only do wide range cassettes? Its also going to be a 1 x set up. Thanks.

    Should work. The GX RD uses offset of the upper jockey wheel to track changes in cog diameter rather than using a slanted parallelogram which follows the cone angle of a cassette. This works for 1x as the change in chain takeup is solely due to the cassette.
    Do the math.

    Assuming the OP has a "1X" GX... there's a "2X" too in both med and long cage

    Edit: oops maybe I misread and the OP only has the shifter at the moment

    If the OP is indeed buying the derailleur, this could be and option too:

    Yes. I currently have GX shifter and an 11-32 11 speed cassette. Need a rear der.

    I didn't know SRAM made wide range road rear derailleur. I assume that works with a GX shifter?

    It should. My newest bike came oppositely equipped with above bar "S" road shifters with a GX rear derailleur.

    For those who are curious - My 11 speed set up with a GX shifter, Rival 22 rear derailleur and 11-32 cassette works great as a gravel/adventure bike set up.
