E13 Helix Race Cassette | 12 Speed |9-50 | Intergalactic

″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.

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.
