e*13 Helix Race cassette, 9-52 t., 12-speed, black

E*thirteen offers expanded drivetrain options for every rider with our original 9-50T Helix Race cassette, which provides a gear range of 533%. Our proprietary 9-tooth sprocket and patented two-piece design allow riders to customize their drivetrain of choice.

Now we have built on this successful formula and added a 52T sprocket for an impressive overall range of 578%.

Do you love climbing hills? Then choose a 28-tooth chainring and conquer some stumps. Want maximum speed? Then opt for a larger chainring and enjoy the widest gear range that a 12-speed setup can offer with a single chainring.
