XT Cassette (M8000) and SRAM GX rear mech – will it work?

Apologies if this has been done but my search didn’t throw anything up.

Was wondering if anyone has tried this or can confirm/deny whether it would work?

I’m looking at a good deal on some SRAM GX cranks, shifter and rear mech to move over to 1×11. My hope hub has the standard shimano driver on so would like to know if I put a Shimano XT M8000 11-42T cassette on would there be any issues in pairing this up with all the 1×11 GX stuff?

Thanks.

I seem to recall a thread on here recently where your proposed setup was working flawlessly for many folk.

Thanks, I’m not surprised there is already a thread I just cant seem to find it!

Usually people do it the other way around* because the Shimano mech and shifter are cheaper and the SRAM cassette has the greater range; your setup should work as well.

Trouble is Id have to factor in an XD driver for the SRAM cassette hence why Im looking at this way round.

For 1×11 with GX, it seems to imply a long cage version of the SRAM GX rear mech is needed? Is this right?

There are two versions of the GX, one that only works as 1x* (and is only available in one cage length), the other that works as both**. If the capacity of the medium caged one is greater than 29 (40 – 11), you could use that in a 1x setup.

l.e: I’m pretty sure the 2x medium-caged one will work in a 1x setup, the long cage is for the 2x setup.

l.l.e: According to the tech docs on SRAM’s website, all GX rear mechs, regardless of cage length, work in 1×11, but the dedicated 1x one should be the preferred option.

thanks otdsr, that is a bit clearer, (apart from the bit in the text for the 1×11 where it refers to it as 2×11 and as having a long cage!)

On the plus side the picture of the 1×11 version looks like the one I was about to order so I think Im good to go!

No wonder i’m confused!

This is what I have and it does indeed work. Prefer the ergonomics of the SRAM levers.

Sram gripshifter , Sram GX rear mech and Shimano 11-42 , 11 speed casette working perfectly here .

When I was having a little bit of wheel faffage fir a short while ran 11 speed SRAM X01 Mech with XT M8000 11-42 cassette on one bike and SRAM 10-42 Casette with XT Mech on the other bike, no issues at all.

Odd.

My lbs is having issues getting up onto big cog (42) and have spotted on this tech doc the need for a spacer?

Seems I have the wrong mech hanger, sram requires a different hanger for canyon than shimano do.

Ooft!.
