    HD4 vs HD5 Head Angle with a 170mm fork
    I notice that the head angles for the HD4 and HD5 are:

    HD4: 64.9 degrees with a 160mm fork
    HD5: 64.2 degrees with a 170mm fork

    I'm wondering how close the head angle of an HD4 with a 170mm fork would be to that of the HD5?

    10mm is worth about 1/2 degree. I will also change seat tube angle if that matters to you.
