DT Swiss LN ACFN3W Freehub Body

For converting DT Swiss 370 road bike hubs, road bike and gravel rear wheels with the Ratchet LN system, to Campagnolo 12-speed and 13-speed N3W 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.
• The N3W freehub bodies can be upgraded using the Campagnolo adapter, item no. AC21-N3W. This allows Campagnolo ED 10-speed, 11-speed and 12-speed cassettes to be fitted.

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

SINC ceramic ball bearings have been developed by DT Swiss as a system. They are based on balls made from the ceramic material silicon nitride, Si3N4, which is extremely durable and resistant to wear and corrosion. The bearing rings are made from a specially developed steel alloy tailored to the properties of the ceramic material and are precision-ground. This combination reduces rolling resistance to an absolute minimum and ensures a longer service life compared to conventional ball bearings.
