    notice the one square notch a dull keyway has to of thease one on each
    side. i would think 2 are beter than 1 but i dont realy know if its
    beter

  3. Well as far as I know, Profiles have a single keyway and quite a few
    people including myself are having problems with slop in the keyway.

    Doesn't it make so much more sence to simply spline the axle the whole
    way through? My ideal hub is an axle splined either the whole way
    through with spacers between the (also splined) flanges, or the axle
    splined through to where the flanges are with a little lip or something
    to keep them in place.

    Thats right, the splined axle for the KH/Onza that is used for attaching
    the cranks also interfaces with each flange disc of the hollow centre
    drum, so there's no need for a keyway. Makes the hub much lighter as
    well.
