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.
