At least 19 different variations under multiple names online. Two main types: light and heavier. They also make 8- and 9- speed ones but I don't think there is any advantage over the now cheap Shimano / SRAM OEM ones. The big advantage once you get to 10/11/12 speed is that the lighter ones really are lighter than average and sell between $100-150; the heavier ones are a lot cheaper than normal, usually range from $50-65. I'll talk about the longevity of them later.

Heavier 10-speed is 11 to 36, 40, 42, 46, 50t; weight is 355-590g
Lighter 10-speed is 11-46 or 11-50t; weight 340-380g

Heavier 11-speed is 11 to 40, 42, 46, 50, 52t; weight is 530-705g
Lighter 11-speed is 11-46, 11-50, or 11-52t; weight is again 340-380g as with 10 speed, not bad!

Heavier 12-speed is 11-50 or 11-52t; weight is 615-710g
Lighter 12-speed is again 11-50 or 11-52t; weight is 480-500g


I've bought a few of the 11-52t's and weighed them, they are fairly correct as above, within 10-20g. The heavier one was just for light-duty stuff, pavement, gravel, some relatively flat singletrack, it lasted 920 miles before I changed the chain and it fell apart and had to be trashed. For $65, it lasted a pretty decent amount of time. Shifting was OK, not quite as good as the lighter more expensive ones but it worked. For $65 I cannot complain at all. The cheaper ones are a 9-speed steel 11-40t cassette merged with two aluminum 46t and 52t cogs.

For the three lighter ones that were also 11-52t, two of them are worn and the third is just getting broken in; I have a fourth on the way. The light ones are a steel 7-speed 11-30t cassette merged with a CNC-machined group of cogs 1-4 that are 52, 46, 40, 34t. The aluminum is good; maybe one of the cassettes had cog 4 wear out a bit early, the rest all slowly wore the steel down somewhere between cogs 8-11.

Longevity? OK...before I get to that with the lighter ones, let me explain that for the two that are worn, one of them was used more for pavement, gravel, and some singletrack with a more XC-oriented rear tire (similar to the heavier cassette discussed above). The other had a DH tire on the back and obviously I tried to ride singletrack as much as possible with that one, so harder pedaling. The one paired with the DH tire lasted pretty much exactly 1000 miles (and is still probably salvageable for a while after a new chain breaks in). The one paired with lighter-duty riding in general lasted 1980 miles and now is slipping between cogs 8-9. So longevity is basically somewhere between 1000-2000 miles. For the money, for the weight, that is really not bad at all. If an extender is not needed, the shifting is more or less perfect. Seriously. Really recommend you to try these out, you don't have too much to lose!

We need a standard disclaimer about receiving compensation for product reviews. I went over to amazn to see the reviews and many rate them one or two stars, primarily for poor quality and materials.

I like (and recomend) Sunrace cassettes that cost around £50 for the 11-42/46, 11speed versions.

Shifting performance is very good but can't provide any in depth or accurate details on weights, relative cog wear, mileage, etc. on any that I've owned previously or on the one I'm running now.

Good info overall, but the longevity is definitely bad for the money.
I have read other experiences on Ztto cassettes that the smallest steel cogs don't hold out long, but they can be replaced with Shimano/Sunrace spares.

How did you took care of your drivetrain/chain on those Ztto cassettes?

Personally I do hunt for higher end Sram cassettes on the used market.
So far got 3 XX1 cassettes ( 11 speed) 100€ each and a brand-new 1175 and 1185 for 70/100€

I don't look for eagle cassettes as the x01/xx1 stuff holds like forever. My 4 year old cassette still got some life to squeeze out 😛

Or like @Reaperactual mentioned, Sunrace cassettes offer great performance/weight for the money.

So my interest in chinese cassettes is very low.

The curiosity however is very high

I've been running a 11-46 11s for the whole season and it doesn't show any signs of slowing down. Tho it is the "gabaruk" style of cassette where cogs 40-11 are machined from one block of steel and riveted to a spider and the biggest cog which can be steel or alloy depending on the version. Shifting is ok but for the price/weight I can live with it which is why I got another one 9/46 XD for my GF and a 11/50 for my next build. The current one has done 2000km, nearly 100,000m of vertical pf which 3 enduro races, 1Dh race, 3 weeks of Bikepark in the Alps.
If your wheels are XD you could go for GX, maybe second hand to match the price. But if your current wheelset is HG freewheel you only have heavy options and for this reason alone those are great.

got another one 9/46 XD

I testet the cheap 9-42 11 speed cassette ( full steel )
Shifting was very good and it was very quite.
Sadly the whole cassette startet creaking like crazy on all gears after 300 miles.
The culprit was the XD shell. Sram cassettes have claws to hold the xd shell in place. But the ZTTO XD shells are just pressed in.
Mine got lose, so no matter how tight I bolt the cassette on, the whole cassette has play and can move a little in all directions which causes that loud creaking.
I planning to get the XD shell out of this cassette and replace it with a Sram one from a death XX1 cassette. If that fails than the whole cassette is for the trash bin.

I've been using the 11sp SLR 2 11-46 for the past couple years with an XTR shifter and XT derailleur. I don't have a ton of miles on it...but its pretty light and still shifts well.
