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.
