Helix Race 12-Speed 9-50T Cassette Replacement Clusters

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 Race 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. If your chain shows 0.5% or more wear, you will significantly decrease the wear life of your new cassette. Installing a new chain with your new cluster is a much better and economical solution.

The Intergalactic 42-50t cluster features PVD finishing which improves durability and wear life.
