Are cheap cassettes durable enough? AliExpress vs Shimano
The reviewer discusses their experience with a ZTTO monoblock cassette, which appears to be the ZTTO Ultimate 11/12 Speed Road Bike Cassette, though the exact model name isn't explicitly stated. They mention purchasing it for Β£66 and highlight its lightweight design at 200g, comparable to Shimano Dura-Ace. The cassette initially shifted well but wore out after approximately 2,500 miles, with the eighth gear becoming completely unusable. The reviewer conducted a hardness test comparing it to Shimano cassettes, finding the ZTTO's steel hardness relatively good but less uniform in hardening. They note the cassette has a basic black oxide coating rather than the more durable nickel plating found on Shimano products. The reviewer replaced it with a newer ZTTO SLR Gen 3 model but expects even lower durability due to aluminum teeth on the smaller cogs.
