After deciding to switch to a 12-speed drivetrain, I began acquiring other components. In my opinion, the most important of these is the cassette.
My first choice was the SunRace CSM901 WA1 12-speed cassette (for [Shimano] HG freehub body of my rear wheel).
Its sprockets are 11-13-15-17-19-21-24-28-33-39-45-51 (teeth).
The 51T sprocket is made of aluminum A7075.
According to my measurements, the cassette weighs 597g. This is about 110g heavier than the SunRace CSMX8 11-46T 11-speed cassette.
