These are the replacement clusters for our Helix Race 12-Speed Gravel Cassette. The Helix Race 12-Speed 9-45T cassette extends legendary Helix shift performance and cross compatibility with SRAM™ and Shimano™ 12-speed drivetrains, to the light weight Gravel and XC marketplace. The 38-45T alloy cluster is easily replaceable so riders can keep their steel cluster for multiple seasons and freshen up the granny as needed without buying a whole new cassette.
When installing the new Helix Race clusters, 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 clusters. Installing a new chain with your new cluster is a much better and economical solution.
