RWS (Ratchet Wheelmounting System)

RWS is the innovative wheelmounting system by DT Swiss. The handling of the Ratchet Wheelmounting System is very simple: ­Tighten up the system by turning the lever clockwise by hand as firm as possible (min. 15 Nm). Depending on the frame ­construction, this can be done by turning the lever several times. Once the wheel is mounted firm and safe, the lever can be aligned in a tidy and safe position. Compared to traditional quick releases, thru axles provide a significantly stiffer and more precise connection of the wheel to the frame.
