E-thirteen E Thirteen Helix Cassette Cluster 11 Speed – Nickel Bronze – 46T

The Helix Advantage
The HELIX R 11 Speed Cassette is an upgrade to any SRAM Eagle™ 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 aluminium one-piece 46 tooth cluster is easily replaceable so riders can keep their steel cluster for multiple seasons and freshen up granny as needed without buying a whole new cassette.

What is Helix?
It’s in our DNA to solve problems. Helix components are engineered to bridge the compatibility gap between SRAM™ and Shimano™ components, ensuring versatility and flawless performance. Future-proof your bike with e*thirteen Helix.

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

Service and Tech Support
Unlike SRAM Eagle™, Helix R cassettes have replaceable gear clusters. That means ongoing service and replacement costs will be less than half that of SRAM™ cassettes.
