I want to change my SX pg1210 12 speeds sram cassette and i don't know if it's ok to buy the same cassette or NX PG1230. I know just i need a heavy duty cassette for my ebike, it doesn't matter the weight. My SX was good for almost 8000km touring mtb but with the new chain X01, the 4 smalest gears skips sometimes when i pedal hard. So what's your advice and what's the difference between pg1210 and pg1230 ? Please help me with your advice. Thank you for your help !

The Sram Eagle range are all interchangeable and I agree with change of cassette, I am using the the NX cassette for the 1st time to see how it works out as really cheap. My setup is GX AXS, NX Cassette, XX1 Chain only setup since last week and just done over 20 miles so far really happy but best to check in about 250 miles.

Not entirely interchangeable. NX and SX both require an HG freehub body.

If your chainring has done 8000km, then I would definitely change it. The SX cassette is all steel, the NX has some aluminium sprockets. For touring use, where weight is not an issue and you just want the best component life, I would probably just stick with SX.
SX and NX Eagle cassettes are very similar, I dont know any particular difference other than NX being about 15 grams lighter and cost a bit more, both are all steel and both have Shimano HG freehub body. Get whichever you can find on stock ...

The top 3 cogs on the NX are alloy

Beg your pardon, it's the spider that's alloy.
i‘ve changed this week my original pg—1210 to the pg-1230
1210 is 714g an 1230 is only 616g!
all cogs are steel - spider material and form are different
shifting is now much more smoother
go for the pg1230 or maybe this set: https://www.bike24.at/p1400314.html

I've only experience of NX Eagle cassettes but if you're only interested in SX/NX level components and an HG freehub I'd also keep a look out for deals on Sunrace cassettes. It's sounds like you're wearing the higher gears more so an alloy granny gear wouldn't be an issue.

Extremely helpful thread. Thought it would be even more helpful to upload front and back pictures of the spiders for the 1210 and 1230 for comparison purposes. The cogs on both seem identical, so upgrading to a 1230 seems unlikely to result in fewer bent cogs. Also putting up a picture of a Blackburn steel tire lever, which I have found invaluable for checking and leveraging a bent cog (looks like they may have stopped making these so grab a pair while and where you can).
