Largest bandwidth. Highest compatibility.

The e*thirteen Helix Race cassette is a high-bandwidth, super-lightweight cassette designed for racing.

The smaller sprockets are made of steel for strength, and the large sprockets are made of high-strength aluminum for weight optimization. The result is a lightweight yet very durable cassette for SRAM and Shimano 12-speed drivetrains.

The tooth contours have been optimized for better shifting performance, and for versatility, the cassette conforms to the SRAM XD standard.
