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

FW2URA-101

Unlike SRAM Eagle, Helix R 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 R 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.
