DT Swiss Road Freewheel Body

These Micro Spline freehub bodies for road bike hubs are 1 mm wider than the version for MTB hubs, thus enabling the use of MTB Micro Spline cassettes on road bikes and gravel bikes.

For converting DT Swiss 370 road bike hubs and road bike rear wheels with the Ratchet LN 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 12x142mm or 12x148mm thru-axle mounting. The right-hand end stops for the mounting dimensions are the same; the hub widths differ.
• Due to the special seal, the Ratchet LN freehub bodies do not fit the Ratchet 350 and 240S hubs, but only the new DT Swiss 370 hubs and wheelsets featuring these hubs
• DT Swiss manufactures separate right-hand end caps 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 caps 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 Star, Ratchet EXP, Ratchet DEG hubs.
Not compatible with MTB hubs and MTB wheelsets.
Not suitable for converting hubs to a different installation size

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.
