Helix R 12-Speed Gravel Cassette

FW2HRA-100

The Helix R 12-Speed 9-45T cassette extends legendary Helix shift performance and cross compatibility with SRAM™ and Shimano™ 12-speed drivetrains, to the light weight Gravel and XC marketplace.

Weighing in at a svelte 319g, this light weight engineering marvel offers an industry leading 500% gear ratio, due to e*thriteen's exclusive 9T highest gear cog.
Our 9T cog also also lets you step down one chainring size, while keeping the same top end gearing, meaning both better ground clearance and an overall lighter drivetrain.
Helix Cassettes were engineered with improved reliability of steel and aluminum assembly, and the 38-45T alloy cluster is easily replaceable so riders can keep their steel cluster for multiple seasons and freshen up the granny as needed without buying a whole new cassette.
Futureproof your bike, save weight, add gear range and spice things up with a touch of color with e*thirteen Helix-R cassettes.

**Not recommended for ebike use. For ebike applications we recommend our TRS+ e*spec or Helix Plus cassettes.**
