More Range, Less Weight The HELIX Race Cassette is an upgrade to any SRAM™ or Shimano™ 11speed 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.
