DT Swiss MTB Freehub Body

For converting DT Swiss 350 and 240S MTB hubs and MTB rear wheels with the Ratchet System to the Shimano Micro Spline System for 12-speed Micro Spline cassettes.

• The kit includes the freehub body and the right-hand frame stop for 10x135mm and Cannondale Boost 10x141mm quick-release mounting. The right-hand end stops for the mounting dimensions are the same; the hub widths differ.
• The Ratchet Star freehub bodies are only compatible with DT Swiss 350, older 240S, 180 MTB hubs and rear wheels fitted with these hubs. A separate version is available for DT Swiss road bike hubs.
• DT Swiss manufactures specific right-hand end stops for each cassette system, such as Shimano HG10, Shimano HG11, Shimano Micro Spline, Sram XD, Sram XDR, Campa ED and Campa N3W. These are also required for conversion if not already present. The right-hand end stops for older systems, such as 3-pawl or Ratchet Star, are also compatible with the new freehub bodies.

Not compatible with Pawl / 3-pawl, Ratchet LN, Ratchet EXP, Ratchet DEG hubs.
Not compatible with road bike hubs and wheelsets.
Not suitable for converting hubs to a different installation dimension

In the Ratchet LN rotor freehub body system of the 370 hubs, the seal sits on the freehub body and not, as with the Ratchet Star system of the 350, older 240 and 180 hubs, in the hub shell. Therefore, the freehub bodies are not interchangeable.

The pawls and springs are the same as those used in the Ratchet Star pawl system.
