The upper stack of a headset experiences minimal load, so caged ball bearings are used here, though we advise care when cleaning this area because water from a hose got past the upper seal after a particularly muddy cyclo-cross ride. The total stack height is 32.5mm and they’re available in both 1in and 1 1/8in diameters.
