  1. The KH06 cranks have a slight angle on them bringing them further out of
    the uni frame (which I like) how do these compare with others, KH07 and
    Koxx for example?
    Do these sit closer to the frame or do they have a taper like the 06
    cranks?
    One last question howcome the older crank and hub set as fitted to the
    KH06 is dearer to buy than the new moment hub?

  2. This angle is known as the Q-factor, the KH 07s have zero Q factor,
    meaning that they are perpendicualr to the axis. The KH/Onza crank
    system is more complex and therefore costly to make than the KH Moment
    system, the cranks are made from 3 tubes welded together instead of a
    single bar and the hub has an aluminium shell pressed on to the axle
    rather than the simpler one piece 07 construction. Does make you wonder
    how they're ever going to shift back stock of the 06 setup but we
    should just be thankful that equipment is getting cheaper.

    Wrong. The '07s have 10mm Q-factor, and the KH/Onza's have 12.5mm
    Q-factor.

    Oh they have a slight kink in them don't they? Exactly how are those
    measurements taken? Putting a ruler across the end of my KH/Onza cranks
    the pedal boss seems to be about 8mm further out than the crank boss.

  5. I don't know how the measurements are taken, but those are the
    measurements Kris gave in the new KH products are here thread.
