The e*thriteen Helix Race 12-speed cassette is engineered to deliver precision shifting performance with an industry leading gear range. The proprietary 9-tooth smallest cog enables the use of a smaller chainring for improved clearance, lighter system weight, and a lower bail-out gear ratio without high gear compromise.

  • Seamless cross-compatibility with Shimano, SRAM, and TRP 12-speed drivetrains
  • Patented 2-Part design provides strength, stiffness, light weight, and ease of service
  • Aluminum and steel clusters can be replaced separately to reduce service cost
  • 9 tooth high gear allows use of smaller chainrings for clearance and weight savings
  • Fits XD™ and XDR™ Drivers Only (Hope XD drivers are undersized at the clamp location and require a Cassette Shim Kit -Sold Separately)
  • Tested extensively for analog and e-bike use
