Is this AliExpress (SUNSHINE Ultralight) worth your money?

After extensively testing it in different conditions, I give my thoughts on the Sunshine Ultra-Light Cassette. I answer some of the most common questions about the cassette, including whether it works in different group sets, performance under different loads, and reliability. I also compare it to the benchmark DuraAce and explain how it performs smoothly in shifting up and down. Moreover, I share my opinion on whether it is a better alternative for racers, club riders, or hill climbers on a budget. In addition to my review of the Sunshine Ultra-Light Cassette, I also provide some extra insights on choosing between different cassettes, including Chines build, 105, Steel + aluminium Chinese Cassette, Ultegra, and DuraAce.
