19:41Which Cheap AliExpress Cassettes Should You Actually Buy?
The reviewer praises the ZTTO Ultimate Gen 2 cassette, noting it is lighter than Dura-Ace but costs only a quarter of the price. They have used it for about 400 km and find its performance on par with Dura-Ace, with good durability expected. They provisionally rate it S tier.
