SunRace CSMZ90 12 Speed Cassette 11-50T Black

The SunRace CSMZ90 12 Speed Cassette 11-50T is a Shimano freehub compatible, 12-Speed Wide-Ratio Cassette. SunRace originated in Taiwan in 1972, initially providing entry-level products particularly to North and South America. The boom in sales of mountain bikes resulted in rapid expansion. Twenty-five years later, it had become clear that further growth would only result from higher level components and so commenced the process of taking the product range up-market.
