The e*thirteen Helix R 12-speed cassette is an upgrade to any SRAM™ Eagle or Shimano™ drivetrain, and offers more range than other cassette options. 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.

  • Works flawlessly with Shimano and SRAM drivetrains, including electronic shift systems
  • CNC optimized for light weight and wide range
  • Helix R is durable and serviceable, with replaceable gear clusters
  • Engineered with improved durability of 2 part steel and aluminum assembly
  • XD driver compatible
