Give Your MTB The Love It Deserves

The Shimano CS-HG50-9 9-Speed Cassette is an excellent replacement part for SRAM/Shimano 2x9 or 3x9 MTB drivetrains, especially the Shimano Alivio group. The distinctively designed HYPERGLIDE sprockets on this cassette incorporate specially positioned shift ramps and tooth profiles for improved chain control during shifting. Fast and responsive indexed shifting is the result.

For optimal shifting, we suggest that you use a Shimano HYPERGLIDE 9-speed chain with this cassette and replace both the chain and the cassette at the same time. Since the two components wear together, they work best when they are replaced together. SRAM 9-speed chains will also work with this cassette, but there may be slightly more noise during the initial stages of wear.


  • Delivers reliable 9-speed mountain bike shifting performance and a durable, silver finish
  • Close gear steps between primary sprockets creates smooth, comfortable pedaling
  • Lightweight design
  • HYPERGLIDE technology
  • Quick and easy assembly with cassette sprocket cap

    Replaced old cassette on MTB with 3x9 drivetrain. Gear ratio was much better than before. Nice finish that added "bling" to the bike.
