Description

Helix R 12 Cassette Cluster

After miles and miles of trail riding, rather than having replace your entire expensive cassette, e*thirteen's Helix R Cassette allows you to replace only the faster-wearing alloy cogs and keep using the heartier steel cogs for multiple seasons. Since the 42-50t cluster is separate, you can replace only those that you've been putting through the paces on the local climb. When it comes time to replace the steel cluster, the 9-36t option will take care of the smaller cogs. The Helix R Cassette is compatible with both SRAM and Shimano systems, with a wider gear range than either with that 9-tooth cog.
  • Replacement clusters to keep your drivetrain performing well
  • 9-36t or 42-50t allows you to replace only the worn part of your cassette
  • e*thirteen's Helix R cassette is compatible with 12speed SRAM and Shimano
  • Multiple color options to add that custom build look

Fast, reliable, light cassette

Familiarity:
I've put it through the wringer

This cassette was a bit tricky to install at first since it is fairly non-conventional, but for any future work there should be no struggles. This is my first e13 Helix cassette, but like the idea of being able to replace either the large aluminum cogs or the small steel cogs separately. It looks great with a decent price tag, and was a huge upgrade from SRAM SX Eagle cassette in regards to shifting reliability.
