I can only describe the visual so far. I can see a bit lower quality finish of aluminium part when comparing it with high-end Leonardi factory parts. Of course. It's 3-times less expensive. Also the steel part is quite basic. But the actual weight 355g (11s 11-46T) is amazing. I hesitate to say "it's great" before trying it. There is overall pesimism about the quality of cheap chinese cassettes. But I hope, it's not the case of this one. It looks like a good choice, and I hope it will work fine. Thank you.
Good cassette. works well and shifts well .. very light ‼️
