E*Thirteen Helix Race 12-Speed 9-50T Cassette IntergalacticHelix Race Cluster 12 speed 42 50T Intergalactic FW2URA 101 Unlike SRAM Eagle, Helix Race 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 R 12s clusters are backward compatible with and can be used to upgrade your existing TRS+ 9 50 cassette. When installing the Helix Race cassette, as with any cassette, we recommend checking chain wear.
