Evening all,

Im in the middle of replacing the integrated headset on my road bike. I was expecting both sets of bearings to come out of the headtube easily, however the lower bearing is well and truly stuck. As far as im aware all bearing for integrated headsets simply sit in the headtube and dont require ‘pressing’ in. Has anyone experienced the bearings for an integrated headset seizing in the headtube?

While most integrated headsets are drop in some of the earlier ones were press in.
As these were installed with a press they also require to be drifted out. Would have thought both upper and lower be the same though. Perhaps debris/grime or corrosion has wedged the lower set in, have you tried drifting it out.
