Helix Race 12-Speed Gravel Cassette — 9–45 Tooth, Precision Aluminum and Steel Replacement Cluster

Description

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 is compatible with SRAM®, Shimano®, and TRP® Shifters and Derailleurs of the same gearing count and similar cage capacity, 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.
