More Range, Less Weight
The HELIX R Cassette is an upgrade to any SRAM™ Eagle or Shimano™ drivetrain, with more range than any other cassette on the market. 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.

Compatibility

Works flawlessly with Shimano™ and SRAM™ 11s 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.

Please reference our hub compatibility article to ensure the e*thirteen cassette will work on the hub you have before purchase.
