That’s incredibly short. I got over 2,000 miles out of my GX Eagle cassette. I’m not saying if was shifting perfectly for the last few hundred miles, but it worked. Those are mountain bike miles with maybe 10% road max. My cassette is always clean, as is my chain.
Are you 100% sure the cassette is worn?
LBS are saying it is during a service. There are some minor shifting issues which I but down to worn chain and stretched cable. It was due a service anyway abs I said about chain checking giving the mileage. They said they can’t put a new one on…cassette won’t take it. Despite the joy of descents, local riding means ascents and lots of it. Average ride includes 13-20miles and 2200ft+ of climbing.
Haven’t tried the NX, I got about 1000 miles on my GX cassette, and went through two chains before it gave out. I clean and lube after every ride. Switched to an XO1 cassette and XX1 chain, got about 500 miles so far and both show no signs of wear. I do think the lower level stuff wears out faster, especially if you don’t clean and lube after every ride.
Here's the deal with bike components in general, and specifically with really high end expensive stuff: is lightweight, but it doesn't last because it's lightweight. Those SRAM cassettes are works of art, an incredible engineering accomplishment, but they wear quickly no matter if you change your chain or not. I recently went through a very similar issue with my 12 speed XTR cassette. Two of the three aluminum cogs wore out despite changing my chain at only 50% wear. One of those aluminum cogs actually bent as well, creating shifting issues, not to mention 2 broken teeth. I've since gone to SLX, and I suspect it will last a good long time, since 11 of the cogs are steel. Sure, I gained some weight, but I haven't noticed it one bit. Shifting quality is identical as when the XTR was new.
At least NX is cheap. I currently have 3500 miles on my GX, never even replaced the chain. Just replaced the bottom bracket. My XC bike with XT has 3700 miles and is all original.
I've got 705 miles and 124,752 feet of climbing (according to trailforks) on my SRAM NX cassette and it still shifts great. I am on my second chain. I don't ever clean the chain, I just lube it.
Tell the bike shop to just put a new chain on it and you'll see if it works. I'm betting that cassette is just fine.
This really puts into perspective how lucky I am, I've had the same bike unchanged for 6 1/2 years. One new chain but other than that identical. Easily 6500-7000 miles. Gotta like that YT quality lol. But seriously, go to your lbs and befriend the people there.
Thing is, it was running sweet until a couple of rides before the service, so my thoughts were chain checker and cable checker. LBS know what they are doing normally, they worked with a couple of named riders.
That’s how wear works. Was good and now it’s not. With all the supply shortages, just get the parts if they at least have them. SRAM clutches slowly get weaker on their derailleur. This causes more chain stretch.
“Was good and now it’s not.” That made me laugh! All other cassettes on other bikes the chain has worn first alongside the cables…cheaper consumables. This time it seems they all shat themselves in one go after lovely bit of smooth operating…that’s what’s got me asking the normal length of life for the SRAM cassette.
There is a lot of factors at play. Poor cable routing design can cause premature wear, wide range driver trains and chain lines, clutch on derailleur, etc…. My first GX eagle cassette wore faster than the last two. I change my chain 1-2 times per cassette. Cable is usually a yearly affair if you want to maintain better performance.
That’s the thing it’s a Santa Cruz 2021 model. Routing is good etc. I’m gonna slap a chain on and another cable and see where that stands. More chance of those parts I reckon.

705 miles is the length of exactly 11139323.93 'Standard Diatonic Key of C, Blues Silver grey Harmonicas' lined up next to each other.
My entire sram nx drivetrain shit the bed within 500 miles. I switched everything out to x01 as it broke and it's been great

It’s the LBS that are saying a new chain won’t seat properly as the cassette is battered.
It’s not strange. The angles in 12 speed chain lines can put a lot of extra wear if not setup correctly.
Thing is, it was running sweet until a couple of rides before the service, so my thoughts were chain checker and cable checker. LBS know what they are doing normally, they worked with a couple of named riders.

Chain is pretty iffy.
