12-speed cassette
Samuel FLYMaster 12-Speed CNC Cassette
A CNC-machined 12-speed cassette from Taiwan, offered as a 182g steel and alloy hybrid for Shimano HG freehubs or a full-steel 10-36T for SRAM XDR. It's a light, durable alternative to top-tier groupset cassettes.
Highlights
Why we rate it
Hybrid HG build
The HG version pairs a one-piece Cr-Mo steel block for the small sprockets with 7075 aluminium on the four largest cogs, saving weight where wear is lowest.
Full-steel XDR option
The XDR version is a solid Cr-Mo steel monoblock, prioritising longevity and consistent shifting.
Wider range than stock
11-36T on HG gives more climbing range than the 11-34T Dura-Ace and Ultegra cassettes, and at a lower weight.
Monoblock construction
Machining the steel section from one piece removes rivets and pins, keeping cogs aligned under load.
Corrosion protection
A multi-layer coating on the steel cogs resists sweat, rain and road grime.
