The HELIX R Cassette is an upgrade to any SRAM Eagle or Shimano drivetrain, with more range than any other cassette on the market. The 9 tooth cog lets you step down one chainring size while keeping the same top-end gearing and provides not only better ground clearance but an overall lighter drivetrain.
The improved tooth profile of the Helix cassette's features Shimano 12-speed level shifting performance with the improved reliability of a steel and aluminium assembly. The Intergalactic PVD finishing is twice as durable as anodised models and is 60G lighter.
These cassettes have a huge 556% range and are lighter than XTR and XX1 models. The aluminium one-piece 42/50 tooth cluster is easily replaceable so riders can keep their steel cluster for multiple seasons and freshen up the granny as needed without buying a whole new cassette. They are even backwards compatible and can be used to upgrade the TRS+ 9-50t cassettes.
