E-Thirteen Helix 11 Speed Race Cassette

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.

The 11-speed cassettes have a huge 511% range and the aluminium 46 tooth cog 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.

Compatibility:

• Works flawlessly with Shimano and SRAM 11s drivetrains, despite the challenges in designing for the different cog spacing and chain behaviour.
