  • Helix R 11-speed, 511% Range, 370-Grams 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.
    • Freehub Mount: XD and XDR Drivers Only
    • Material: 1 aluminum cogs, 10 steel cogs. PVD finishing on Intergalactic model improves durability and wear life.
