Sunrace MZ903 11-51 Cassette, Shimano 12 Speed Compatible, Standard Freehub (517g)

Shimano's 12 speed is great. Its really great. But there's a catch; you have to use the Microspline freehub body, and right now there's very few wheels that offer that. So we scoured the world for the best option, and in what might be another Bird first we bring you the brand new Sunrace 11-51 Shimano 12 speed compatible cassette. Building on its popular 12 speed SRAM compatible 11-50 options the new cassette is fully Shimano 12 speed compatible.

We've tested this out and it works really well so rest assured this isn't a bodge job - have 12 speed shimano AND your choice of wheels. What's not to like?
