Are cheap cassettes durable enough? AliExpress vs Shimano

1 year ago, I started using a cheap lightweight cassette from Aliexpress. 12 months later, how is the durability, and how does it compare to a Shimano cassette? SIROKO CLOTHING – 10% off (automatically applied via link below): https://srko.co/tracevelo I am ALWAYS looking for ways to make my road bike lighter, so when I saw a cheap lightweight mono-block cassette from ZTTO on AliExpress, I had to pick it up. Despite being made of steel it weighs just 199g and seemed very good quality. The shifting performance was also excellent, and costing just £66 i was very impressed. However the long term durability hasn’t been fantastic. I would normally expect to get around 5000 miles, or roughly two chain replacements out of a standard Shimano cassette, however from this ZTTO cassette, I only managed to get 2560 miles… In this episode I will discuss the construction of this cheap ZTTO cassette, compare the grade of steel used to that of a Shimano cassette, and also deep dive on the different coatings used to mitigate rusting/oxidation, reduce friction, and improve overall durability.
