Helix Race 12sp 13-52T Cassette Aluminum & Steel Replacement Clusters

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. 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 economical solution. The Intergalactic 45-52t cluster features PVD finishing which improves durability and wear life.
