    it is the diameter of the steerer tube of the fork.

    the way you measure a diameter, across the circle.

  • do you measure from the outside of the headtube and fork, i know these are simple questions but i just wont to get it spot on as the parts im wanting to get are not very cheap cheers.

    it depends on what you are wanting to measure.

    for the steerer it is the out side while it is the inside for the stem.

    bars outside/ stem inside.

    seat post out side/ seat tube inside.
