If that is the case, your best bet when something goes bad (and stuff will go bad), is to replace the part with something better designed and manufactured.
[MENTION=209177]3alarmer[/MENTION] It's a
2010 Sputnik (Jamis) that was set up on the fixed gear side of its flip flop hub. The headset is original from what I can tell. I've only worked on bikes that I've owned for the most part (limited), but the ones I've seen have been built similarly. The assembly is like the one about two-thirds down the page here:
Servicing Bicycle Headsets In my pics of the fork, the crown race is still on the fork, for reference. I hear you on the benefits of replacement. I think I'm leaning towards replacing the headset because the frame and fork is what interested me most, and pushed me to buy the bike anyways.
[MENTION=103762]onespeedbiker[/MENTION] Could be the case...I don't remember checking that when I pulled it out, so maybe. The groove that takes off the inner part of the cup is smooth and distinct, so my guess is that it was not seated properly. Maybe upside down, too.
Also, if anyone wants to see the top cup, here are a couple pics. To compare, on the lower cup pictures from before, the damage is to the inner "ring" of the cup.
