Helix Plus 12-speed, 556% Range
More Range, Less Weight @406g
Engineered for E-bike durability and cross experience compatibility with SRAM™ and Shimano™ drivetrains.
This 9-50T combination is the hot set up for your 12 Speed MTB and allows for a 2 tooth smaller front chainring, shorter chain length, more clearance and range with our exclusive 9 tooth smallest cog.
Helix Plus 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 12s clusters are backward compatible with and can be used to upgrade your existing TRS+ 9-50 cassette.
When installing the Helix Plus 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.
e*13’s Gen2 TRS Plus Cassette now has 1 aluminum cogs and 10 steel cogs for dramatically increased strength and long-term durability. This makes it our first E*Spec rated cassette, and suitable for e-bike use.
Impressive Eagle™-besting range, updated shifting, a unique two-piece assembly for individual replaceability, and our exclusive 9t cog, deliver a winning combination of features for unbeatable value.
