Helix Race 12sp 9-52T 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 Helix or TRS+ 9-50T cassette. The 43-52T aluminum section will fit on your old 9-50T steel section for increased range.

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 more economical solution.

The Intergalactic 43-52t cluster features PVD finishing which improves durability and wear life.
