The Helix R 11-speed sprocket is an upgrade for any SRAM Eagle or Shimano drivetrain. It offers the widest range and the lowest weight of any cassette available on the market.
Compatibility: Both the Helix R 11-speed and 12-speed sprockets work flawlessly with Shimano and SRAM 11-speed drivetrains, despite the challenges in design for the different tooth spacing and chain behavior.
Performance: The improved performance of the new Helix sprockets from e*thirteen is characterized by excellent Shimano 11-speed shifting performance and enhanced reliability of the steel and aluminum components. The new intergalactic PVD coating is twice as durable as anodized models.
