SunRace CS-M90 Cassette — 9-Speed, 11–32T (Silver)
The SunRace CS-M90 cassette is a durable, service-proven 9-speed MTB cassette designed for smooth shifting and reliable performance across mountain, hybrid, and commuter bikes.
Built with SunRace Super Fluid Drive™ technology, the CS-M90 delivers consistent, predictable gear changes with improved chain engagement across the cassette. Steel cogs and a steel lockring provide excellent wear resistance, making it a strong choice for high-mileage bikes and everyday riding.
With an 11–32T range, this version offers a balanced spread of gearing—ideal for riders who want solid climbing ability without the extra jump of a 34T large cog. It installs on standard Shimano HG-compatible freehub bodies and serves as a direct functional equivalent to several popular Shimano 9-speed cassettes.
