The thirteen Helix cassette is compatible with SRAM and Shimano 12-speed shifters, chains and rear derailleurs. These cassettes are not approved for use on e-bikes.
The Helix Race cassettes from thirteen feature the SRAM XD cassette mount. Compatible only with rear wheels featuring the special XD freehub body; not compatible with HG or Micro Spline freehub bodies.
