• Also radially, no?

    You'd have to do maths and stuff to see whether that was true. The basic triangulation means that more crossings makes for more radial stiffness because the spoke is closer to parallel with the plane of the wheel (for the same reason, fewer crossings means more axial stiffness, because the spokes are closer to parallel with the axis). More crossings means longer spokes though, so there's a slight loss of radial stiffness just because there's more stretchy wire in the load path.

    In the great scheme of things, the difference between 2X and 3X 28H wheels is swamped by other factors, so it's not worth getting hung up about unless you are so heavy and/or aggressive that you're loading them to their critical point in some circumstance, and in that case you should be using 36H anyway :)

  • Ouf, that exceeds my understanding.
    What I don't get though is why less spokes mean more axial stiffness. Doesn't that depend on the hub width?

    It's not fewer spokes, it's fewer crossings. This increases axial stiffness by decreasing the vertex angle of the cone containing the spokes. A witch's hat is harder to crush vertically than a Chinese farmer's hat is.
