Very lightweight quality item as shown in the publication
K***y –
Very light, used for around 350km so far, not as quiet as hoped but noticed a shifting difference when changing to dura ace chain.
j***n –
This is my second purchase, good quality lightweight cassettes. Shift really well and not too noisy.
AliExpress Shopper –
It was 10g heavier than the HP label, but I’ll accept it.
D***i –
The fabric seems well-made and it’s very light…we’ll see…for now I’m satisfied.
AliExpress Shopper –
A great product, looks good for the price it has. Let’s hope it lasts and gives good results over time. If I have any issues, I will give another opinion.
C***E –
The cassette seems well-made and it’s very light. On my bike, it works well. When mounted, it has a bit too much play in the freewheel (Shimano cassettes are much better adjusted). But once everything is tightened, it spins smoothly and doesn’t move. So it doesn’t worry me too much. It will work. My opinion is therefore quite positive and I think I would buy it again.
K***i –
Very light. Not tested yet, prevoius cassette was not shifting very good. I hope this one is improved (this is why only 4 stars)
M***a –
Looks great but is heavier than advertise (12 speed 11-34 is advertised to be 142 grams, not 154). Still much lighter than other companies though.

Very lightweight product but does not function like the original Shimano. I definitely wouldn’t buy it again.

Great cassette, very light, flawless shifting.
AliExpress Shopper –
Very nice and light, only 160 grams 11-34. What I found cool is that it’s a unique construction, making assembly easy, on the other hand! If you lose a pinion, you have to replace the whole part.

138g. an output with ras no more noise than the dura ace except on the 27 and 30.

D***l –
Excellent product
A***e –
This is the second 11/34 ZTTO cassette I am buying. I use one with the Dura-Ace 11-speed and one on my Dura-Ace 12-speed. The weight of 160g is correct, the cassette is one-piece and looks good quality-wise. It probably won’t last as long as a Shimano cassette, but I accept that with the weight savings and affordable price.
E***r –
super light, first test great
A***e –
11-32 cassette very light (138g) but not yet tested, to see how it performs over time with use.
AliExpress Shopper –
Good quality works well, easy to install weight exactly asmadverosef

There was no problem at all and it was a good product.

Lightweight cassette in one piece, not as quiet as a Shimano
Aesthetically stunning
a***r –
Very good quality and excellent service!!!
AliExpress Shopper –
Very light, simple, works very well with the Dura Ace 12s, you won’t have to replace a single cog as it wears out. The cassette is made of a single element.

I have several cassettes of this model, beautiful, lightweight, and cheap.

Excellent and smooth, very satisfied 😉
T***o –
Super fast shipping. At first glance, it’s a cassette spectacle, weighs very little and fits perfectly on a GRX Di2 with little adjustment. I’ll add an additional comment if it starts to go wrong; we’ll see how long it lasts, but it’s beautiful.
AliExpress Shopper –
Véry nice product
S***r –
Very happy with product, shifting is good enough with no noticeable differences .. 11-32 weighed 138grams
AliExpress Shopper –
2nd one of these i have ordered, great value for money.
AliExpress Shopper –
weighs 126g, I found it to be a good weight. The rest I need to test to see how it turns out.
AliExpress Shopper –
very light. 132g. Durability still needs to be tested, will report accordingly.
AliExpress Shopper –
It’s very nice and works perfectly, just need to test the durability…

J***g –
Fast delivery. Well packed.. good product.
AliExpress Shopper –
It was about 10g heavy, but overall I am satisfied.
AliExpress Shopper –
126 grams in 11s 11-28t
AliExpress Shopper –
Excellent. 131 grams for the 11speed 11-30. looks cool. shifts great.
AliExpress Shopper –
arrived two days earlier than expected. Actual weight 133g.. in the 12v 11-28 version
So light that it feels like it’s fake. First ride without any problems, changed back to how it was before (I have Shimano Di2).
I will come back here after 3,000-4,000 km to tell you about the durability.
R***r –
Just received this when youtube let me know that this is fragile. Apparently the two largest cogs like to brake off from the rest of the cluster. It turns out that there is a 2nd generation that is somewhat more robust. And, the 2nd gen was available when i got a 1st generation. It is improper to ship out product that the manufacturer has obsoleted because it was defective and potentially unsafe. I’m disappointed.
G***a –
Apparently well done. Lightweight. I will assemble it at the beginning of the athletic season.
For now, it stays in the box.
o***a –
12 speed hg 11-34 weighed in at 164g, so 15% more than advertised. Still, this is way lighter than the dura ace of the same size (255g). Took one long ride so far and it shifts just fine with di2 ultegra set, can’t tell any difference and didn’t have to make any adjustments so this seems like a perfect swap. Will report back on durability over time.
C***p –
Unbelievably light
C***u –
Very lightweight and beautifully looking. It shifts well from the get go
g***r –
Ok this is an amazingly light cassete, and the changes on a shimano di2 are flawless. But. If someone is a heavy a rider or strong, needs a lot of attention on the top 3 alloy cogs. These are very fragile and need to be used only in emergency or on a lower power numbers. If you know that and try to avoid these cogs the cassete will last a bit. If not, these are going to fail in less than 1000km. I bought a bigger cassete so i can use mostly the steel cogs so it will last. I’ll write an update later on
k***r –
Perfect sprocket package, very well made and extremely light, 141g
