The HELIX Race Cassette is an upgrade to any SRAM™ Eagle™ or Shimano™ shifter and derailluer combination*, 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.

Features
