Helix R pakan alumiininen osa 42-50T. Tarvitsee osaksi Clusterin (E13 Helix Race Cluster).
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. As an added bonus, Helix R 12s clusters are backward compatible with and can be used to upgrade your existing TRS+ 9-50 cassette.
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.
The Intergalactic 42-50t cluster features PVD finishing is twice as durable as anodized models.
