Product details
The Helix R 11-speed cassette 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 cassettes work flawlessly with Shimano and SRAM 12-speed drivetrains, despite the challenges in design for the different tooth spacing and chain behavior.
Performance: The improved performance of the new Helix cassette from e*thirteen is characterized by excellent Shimano 12-speed shifting performance and enhanced reliability of the steel and aluminum assembly. The new intergalactic PVD coating is twice as durable as anodized models and is 60 g lighter.
Cost-effective solution: The connected 42/50 aluminum sprockets are easy to replace, allowing riders to keep their steel sprockets for multiple seasons and renew the old ones as needed without having to purchase an entirely new cassette.
