Description
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
- The patented 2-Part design provides strength, stiffness, lightweight, and ease of service
- Aluminum and steel clusters can be replaced separately to reduce service cost
- 9-tooth high gear allows the 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
