    SRAM gx 1x11 adjustment screws

    Does anyone know which screw is the high and which is the low adjustment screw. I'm guessing the screw on the bike side is for the smaller cog, and the screw on the outside is for the larger cog. Anyone know?

    That's a serious question. Impossible to find out by yourself. It actually reminds me of the "does somebody know with which side up I plug in the USB drive into the usb port" from the computer forums

    Translation: you'll find out for sure as soon as you just try adjusting the screws.

    Note, generally speaking you're first instinct is correct. Try the inside screw first.

    Old enough to know better. And old enough not to care. Best age to be.

    I just got a bike with SRAM GX 1x11 rear derailleur and I can't figure out how to adjust it properly (gears keep jumping up and down on the largest cogs in the rear).

    The manual at SRAM site is totally useless for this model. In the images in the manual there is some other SRAM MTB derailleur that has different adjustment screw placement..

    cable tension needs to be adjusted, that is done at the shifter.

    I think you're looking for the wrong type of information. What may help you is a document explaining the underlying principles on how a bicycle gearing actually works

    While you are correct in that I need to study more about how bicycle gearing works, I find it unacceptable that SRAM doesn't have a proper manual for a gearset that costs this much. All they have is a generic manual for "MTB gears" and what they show there is very different from the GX derailleur.

    Did you confirm that you routed/attached the cable correctly for your particular derailleur? The docs (see link below) indicate that it's different for the GX 1x11, 2x11, and 2x10 models.

    The doc also has a brief troubleshooting section near the end (around page 19).

    The OP is right. His derailleur is very different from the ones in SRAMs manual. Someone must have found the adjustment screws.

    The high & low adjustment screws are on the back of the derailleur.
