DT Swiss Aluminium Rotor Hubs, Ratchet LN Sprocket System, Road Bike Sram XDR 12-speed, without end stop
DT Swiss freehub body
For converting DT Swiss hubs with the Ratchet LN system to the Sram Road AXS 12-speed XDR freehub body
Due to their special seal, the Ratchet LN freehub bodies do not fit standard Ratchet 350 and 240 hubs, but only the new DT Swiss 370 series hubs and wheelsets featuring these hubs. Conversion kits containing sprockets, springs and a hub insert are available for converting the old 370 series hubs to the Ratchet LN system.
DT Swiss manufactures its own right-hand end stops for every cassette system, such as HG10, HG11, SRAM XD, Campagnolo, Micro Spline, etc. These are also required for conversion if not already present. The right-hand end stops from older systems, such as 3-speed or Ratchet Star, are also compatible with the new freehub bodies.
