SunRace CSMZ90 12-Speed 11-50T Wide-Range Cassette - Silver

Season:2018

Brand:Sunrace

Code:CSMZ90WA5M

The SunRace CSMZ90 12‑Speed 11‑50T cassette delivers a wide gear range and reliable shifting performance for mountain biking, trail riding, and all‑terrain cycling. Featuring a robust construction with alloy spiders, spacers, and lockring, this cassette offers a lightweight yet durable solution for riders seeking a broad 11‑50T gear spread to conquer steep climbs and fast descents.

Designed to fit Shimano/SRAM compatible HG freehub bodies, the CSMZ90 cassette is ideal for riders who want a wide‑ratio option without the need for expensive XD or Microspline specific hubs. The cassette includes 12 sprockets with the progression 11‑13‑15‑17‑19‑21‑24‑28‑32‑36‑42‑50T, giving a versatile ratio for mixed terrain riding.

Built with a combination of high‑tensile steel and alloy components, the SunRace CSMZ90 balances durability with weight savings. Larger sprockets are supported on alloy spider carriers to reduce weight while maintaining strength where it’s needed most.

Whether you’re upgrading your drivetrain or replacing worn components, the SunRace CSMZ90 offers dependable performance and extended range gearing at a value‑focused price.

Key Features:

  • 12‑speed wide‑ratio cassette with 11‑50T range — ideal for MTB and off‑road use

  • Compatible with Shimano/SRAM HG freehub bodies (not XD/Microspline)

  • Alloy spiders, lockring & spacers for lightweight strength

  • Hi‑tensile steel and A7075 alloy sprockets for durability where it counts

  • Smooth shifting across a broad gear range for climbs and fast terrain

  • Finish: Silver
