The e*thirteen Helix Race cassette inspires with high bandwidth and a super low weight for racing use.
The smaller pinions made of heat-treated CrMo steel contribute to the strength. 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 for SRAM and Shimano 12-speed drives.
The tooth contours have been optimized for better performance when shifting and for high versatility. Compatible with the SRAM XD standard.
