Cassettes & Cogs E-Thirteen Helix 11 Speed 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.

When installing the Helix R cassette, as with any cassette, it’s recommended to check for 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 and you’ll thank yourself later.

The Intergalactic 46t cluster features PVD finishing is twice as durable as anodised models.

Available in separate pieces to suit which part of your cassette needs replacing:

• Speeds:11-Speed
• Aluminium Cluster: 46t
• Steel Cluster: 9,11,13,15,17,20,24,28,33,39t
