The e*thirteen Helix Race 12-speed 9-50t cassette is an upgrade to any SRAM™ Eagle or Shimano™ drivetrain, and offers a 556% range. 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
- Durable and serviceable, with replaceable gear clusters
- Engineered with improved durability of 2 part steel and aluminum assembly
- XD driver compatible
