    Currently looking for headset ball bearings for the Campagnolo headset lower bearing (about 5mm diameter).

    Then I can refit the forks, put some wheels on & try to remove the bottom bracket cups!

    I have an old Shimano 105 1055 triple groupset I am planning on using for it.
    All beater grade.

  • I have a set of Facom vernier gauges which are not the most precise.

    The to upper bearings were about 4mm while the lower bearing were about 5mm.

    So from what I measured I think they are 3/16" / 0.187 = 4.76mm
