e*thirteen Helix Race 12 Speed 9-52T Cassette

e*thirteen turned the bike world on its head with the introduction of the 9t sprocket on the original TRS cassette in 2015, and they have never looked back! 

The newest generation of e*thirteen Helix cassettes deliver more range than the competition with unmatched cross-compatibility for flawless shifting performance with SRAM™,  Shimano™ and TRP drivetrains. Lighter in weight, they also enable you to shave grams by stepping down a chainring size. 

Our cassettes also maximize service life by enabling you to replace the steel or aluminum parts separately; and they come in a rainbow of colors to match your style! Reduce weight, increase range, personalize your bike, and experience freedom of choice with e*thirteen Helix cassettes.

PRODUCT SPEC Compatibility - Please reference our hub compatibility article to ensure the e*thirteen cassette will work on the hub you have before purchase.
Freehub Mount - XD™ and XDR™ Drivers Only
