e*thirteen Helix Race Cassette | 11-Speed | 9-46 Teeth | SRAM XD - bronze

The e*thirteen Helix Race cassette inspires with high bandwidth and a super low weight for racing use. To the strength contribute the smaller pinions of heat-treated CrMo steel. For weight optimization, the large pinions were made of high-strength aluminum. This results in a lightweight and at the same time very durable cassette. The tooth contours have been optimized for better performance when shifting and for high versatility, the mount complies with the SRAM XD standard.
