The e*thirteen Helix Race 12 Speed Cassette have replaceable Gear Clusters, keeping replacement costs to a minimum. Use to upgrade your Helix or TRS Plus too!
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 a bonus, e*thirteen Helix Race 12 Speed clusters are backward compatible with and can be used to upgrade your existing Helix or TRS+ 9-50T cassette. The 43-52T aluminium 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.
