Run the cassette you want on your DT Swiss hub. This is the SRAM XD freehub body for the Ratchet System (Star Ratchet) system, supplied as a complete kit with the drive-side end cap so it drops straight onto a mountain bike hub.

Highlights

  • SRAM XD driver — runs SRAM Eagle and 12-speed MTB cassettes (XD driver).
  • Ratchet System (Star Ratchet) — matched to DT Swiss 240, 350 and 440 Star Ratchet hubs.
  • 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?

The classic two-piece Star Ratchet shares one freehub interface across the 240, 350 and 440 — engagement (18, 36 or 54 tooth) is set by the ratchet rings inside the hub, not by the body. Use this body with DT Swiss 240, 350 and 440 Star Ratchet hubs. 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.
