  1. How much does a conventional headset (e.g. Chris King)
    increase the effective length of the head tube compared to
    an integrated headset? I will buy a custom size frame with
    conventional head set and I am using my present frame as
    basis for specifying my new "ideal" frame geometry and my
    present bike has integrated headset.

    An other way to put the question: How much shorter must the
    head tube be on the new frame with conventional head set if
    I want to use my present fork with given steerer tube length
    without reducing the spacer height?

    The "stack height" specified for the headset tells you how
    much steer tube length is "used up" by the headset. Add that
    to the head tube length and the stem clamp length, subtract
    5mm, and you've got the minimum steer tube length that you
    can shop for.

    By the way, integrated headsets have a potentially serious
    drawback. Go with an *internal* headset instead, to achieve
    the same result without the inherent problem More about the
    issue can be found here:

    One more caveat: it is likely that the greatest degree of
    servicability and long-term economy will continue to be
    achieved via the use of a conventional headset, at least for
    the near future.

    There is some disagreement about the significance of the
    alleged advantages of an internal headset over a
    conventional one.

    Yes, and I found some more information on the web. The
    typical stack height for a conventional 1 1/8" threadless
    headset is 31.4 mm (Chris King) while the corresponding
    value for an integrated headset is about 10 mm.

    I have one; is there any advantage other than the ability to
    get the stem mounted lower? That's one advantage that I
    don't need anyway...

    What's the 5mm? Is that the maximum suggested gap betwen the
    top of the stem clamp and the top of the steerer?
