The HELIX R Cassette is an upgrade to any SRAM Eagle or Shimano drivetrain, with more range than other cassettes 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.
