Helix Plus 12-Speed 9-50T Cassette Aluminum & Steel Replacement Clusters meta-related-collection-chainguide-parts Exclusively engineered for e*thirteen's DHHelix Plus cassettes have replaceable gear clusters. That means ongoing service and replacement costs will be less than half that of SRAM cassettes. As an added bonus, Helix 12s clusters are backward compatible with and can be used to upgrade your existing TRS+ 9 50 cassette.
