E*thirteen Helix Race Cluster Cassette 11S Sram, Shimano

Helix R cassettes have replaceable gear clusters. That means ongoing service and replacement costs will be less than half that of normal cassettes.
When installing the Helix R 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 economical solution.
he Intergalactic 46t cluster features PVD finishing is twice as durable as anodized models.
