I bought a used Trek 8500, probably from '96, with an Aheadset (Kontak SA or ST I think). I'd like to clean and repack the bearings on the headset, and have already loosened and removed the stem, spacers, and rubber seal from the headset stack. Now I'm down to an (aluminum?) split ring(?) inside a black metal top race(?) -- see photo for details. How do I remove the split ring/top race? Should I just gently bang on the top of the steerer tube to have the top of the head tube push up the top race and split ring? Should I try to pry the split ring up?
