SPARE Helix Race Cluster| 12 Speed | 42-50T | Bronze (CTN20)

SPARE PART ONLY - 2 x Aluminium cogs 44-50T

Unlike SRAM™ Eagle™, Helix R 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 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.
