e*thirteen Helix Race Steel Replacement Cogs - 9-32T | 12-speed - nickel

Replacement cluster for e*thirteen Helix Race Gravel cassette. These are the replacement clusters for the 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. 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. made from nickel plated steel 9, 11, 13, 15, 17, 19, 22, 25, 28, 32 Note: This cluster is a part of a cassette and cannot be used on its own!
