• Maybe this image helps a bit, offset rim helps to make the hub-rim-spoke triangle more even and allows for more even tension between the drive and the non-drive side of the wheel, which makes a stronger wheel. As @Emyr pointed out a longer freehub body results into a less even tension than a 'normal' shorter freehub body. An offset rim helps to compensate

    tldr left triangle is more 'even' and therefore stronger

  • Thank you. Let me rephrase, none of my 10 speed wheels built on not offset ever needed retruing before replacing. Maybe a bit leading now: the wheel builder wouldn't really need offset to achieve the same result with 11 speed?
