Wanted extra range for climbing so got the 11-36, weighs 163g. Shift quality is 8/10 points compared to the dura ace 11-34 which is more than acceptable to get something significantly lighter and with lower gears.
N***a –
It weighs a little more, but it’s fine.
AliExpress Shopper –
Very light. 1 block. easy to install. no issues with 12 spd shifting. looks bling bling ££

Excellent quality product. It’s exactly as advertised by the seller, easy communication, and quickly shipped. Very satisfied!!!

Previously, Third Perdy’s sprocket was not something that could be used just because it was light.
This product was very light and had more than enough shifting performance for hobby riders.
Personally, I think it might have better performance than the 9100 Dura.
The improvement of China’s technology is truly remarkable.
I will also purchase an additional 34T sprocket.
Thank you very much.

Too perfect 👍✨

Super light, perfect shifting with di2.

Excellent, full store – fast shipping 9 days to Colombia. the best. Now let’s assemble and check the duration.
200 grams less than a Shimano 105, I like it, nice.
AliExpress Shopper –
very light and beautiful, but I haven’t installed it yet
翔***場 –
It’s definitely lighter than Shimano’s Ultegra! And it’s sturdy too!
AliExpress Shopper –
Product conforms to the description, except for the weight, which is 14 grams higher than advertised. The shipping was fast. It needs to be assembled and tested, but the appearance is good.
AliExpress Shopper –
Excellent craftsmanship and beautiful appearance. The weight was slightly higher (128g instead of 112g), but it still weighs half less than the previous cassette (which was already light).
a***a –
very light
AliExpress Shopper –
The cassette looks good, this is the second one I’ve bought; the first one was 11t, this one is 12t, so I know the result is optimal. The weight is a little more than advertised but not by much.
a***r –
Unfortunaltly the quality of the product was not good. The 5th sprocket was broken and the chain keeps to jump out.
AliExpress Shopper –
Received quickly mounted on an Elite wheel with a 38 profile.
It works great and is very light.
I am very satisfied.
AliExpress Shopper –
Very light and after 1000km no problems. I use Shimano Ultegra Di2 (current model), the gear shifting wasn’t perfect, it took me a while to get it adjusted properly.
G***y –
I was looking only for the correct range 11-36. when it arrived i could not believe how light weight this is.
AliExpress Shopper –
Anyway, it’s light! The durability doesn’t seem that bad either. It didn’t take much time to arrive🛬
AliExpress Shopper –
The cassette is very light and I liked it, unfortunately I had to return it due to a mix-up in the order and received one with 11 speeds (11s), I need 12s. The amount was refunded to me as a bonus on the same day I took it to the post office.

Quality is top-notch!

I got the 11-speed 11/32 version. This is composed of 2 monoblocs, the large aluminum sprockets, fixed with 7 pins to the second steel monobloc which has the smaller sprockets. in the gen. The previous two were both made of steel, and the removable pins allowed for the complete disassembly of the sprocket pack to improve the dimensional tolerance of the plastic layers and make the cassette as precise as an Ultegra at a much lower price and weight. This cannot be done on this one, but the monoblock construction allows for greater precision, which I have personally verified with a caliper and thickness gauge. It’s much better than Gen. 2, well done ZTTO.

Excellent product meeting expectations

Sram 11/12 chain runs well. In two gears, the chain noise is a bit louder. But I don’t notice any difference from the original cassette by Sram. The durability and quality will become apparent over time.
