Hi mate. I'm pretty sure the bearings match up - just the inside diameter is different to accommodate the different size stems. To the best of my knowledge - Duke 2 bearings are L45449 1.98"OD, 1.417"ID, 0.56 depth/height and Berg bearings are L44643 1.98"OD, 1"ID, 0.56" depth. In theory all that should be required is for the Duke stem to be shortened. If that's not possible due to the profile of the stem narrowing, maybe the stem can be pressed out and a spacer/packer of the correct size can be introduced under the bottom yoke to draw the stem down to the size needed (again, if the profile of the stem allows enough space for the bearing still). Just a suggestion I'm putting out there for consideration - might well not be possible!
