I wouldn't worry too much about it. My experience with A9 headsets is that they are virtually indestructible, even with long term neglect. As an experiment, I set up my commuter bike with an A9 headset and rode it in all kinds of weather for 20 years without any maintenance whatsoever. In 2008, after 20 years, I opened it up, cleaned off the old grease, and this is what I found:



Some minor discoloration on the lower race, but nothing more. I swapped upper and lower races, reassembled, and will ride it for another 20 years and report back again.

At this point, I have half a dozen bikes with A9s installed, and a Delta (similar design, but with O-ring seals on the cups) on my tandem.
