- 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.
- Compatibility: Works flawlessly with Shimano and SRAM 12s drivetrains*, despite the challenges in designing for the different cog spacing and chain behavior.
- Additionally, if your wheel has a SRAM XD Driver and you want to upgrade to Shimano 12s, you not only save money on the cassette and don’t have to spend the extra on a new hub driver.
- All e*thirteen cassettes require XD drivers for mounting
- Please reference our hub compatibility article to ensure the e*thirteen cassette will work on the hub you have before purchase.
- Freehub Mount: XD and XDR Drivers Only
