Run the cassette you want on your DT Swiss hub. This is the Shimano Micro Spline freehub body for the Ratchet LN system, supplied as a complete kit with the drive-side end cap so it drops straight onto a mountain bike hub.

Highlights

  • Shimano Micro Spline driver — runs Shimano 12-speed Micro Spline cassettes.
  • Ratchet LN — matched to current DT Swiss 370 hubs and many OEM-spec wheels.
  • Kit, not just the body — includes the 12×142 / 148 drive-side end cap.
  • Aluminium body — the standard DT Swiss alloy freehub.

Will it fit?

Ratchet LN carries its seal in the body itself, so it also converts a 3-Pawl hub to ratchet engagement. Use this body with current DT Swiss 370 hubs and many OEM-spec wheels. It is set up for 12×142 / 148 spacing. Changing cassette standard also means matching the drive-side end cap, which is why DT Swiss sells these as kits. If you are not certain which ratchet system your hub uses, ask us before ordering.

Covered by DT Swiss's manufacturer warranty against defects in materials and workmanship. If you ever have a warranty concern, return the part to Tune Cycles and we'll handle it with the distributor on your behalf.
