Cassette choice

[Pizza_EMTB]

Hey everyone i have a 12 speed sram system with a gx axs deralier and a nx cassette that has worn out recently and was condering what cassette I should go for when I want max durability.

I am not willing to get rid of my gx axs deralier and I have a hg freehub body.

The options I have seen are sunrace e bike specific, sram nx, sram sx and give me any other ideas if you can think of any.

If you have any experience or knowledge with these or ideas for other cassettes then feel free to say your opinion and help me decide.
Thanks

Any SRAM Eagle cassette is compatible. Most GX Eagle equiped bike use the SRAM XG 1275 10-50 or 10-52

Stick with a new NX cassette, unless you want to change your Driver body to the XD

Do you know if the sx dousent last as long then?

The SX is the lowest line of the Eagle range

Id honestly stick to the NX and potentially get a better chain to prolong the cassette life

I run GX AXS derailleur, NX cassette and about to change to an XX1 Chain

Yeh the reason I found out it was worn is because I bought a new kmc e bike chain and it was skipping around everywhere when in turbo and auto modes

NX is all Steel but only the last 3 gears are pinned. GX is all steel apart from the 50 or 52t cog (ally) but is fully pinned. Sitting on a XD driver rather than a HG also contributes to making the cassette more secure.......using a HG cassette often leads to the cassette gougeing the splines on the freehub body. So overall, changing to an XD driver and a GX cassette is a better option in my opinion. albeit more expensive than merely changeing for a new NX cassette.

That said, cassette wear is largely caused by the chain. GX and X01 are the best quality Eagle chains for an Ebike. GX should last about 500 miles, x01 possibly 1000 miles ( both to 0,5% wear)due to a harder coating, but then X01 is twice the price of the GX so it works out a bout the same (XX1 is merely lighter so a lot more money for no real benefit over the X01). NX chains are not good!!

Do you know about the sx cassette though? Everything I have seen it looks like it's the same as the nx but the cassette is heavier and dousent have a spider so it's separate

Also I have a kmc e bike chain, hopefully last a while
