    Fork crown race got powder coated

    so i just got back from the powder coat shop to pick my bike up and noticed they powder coated the fork crown race. Is this a big deal? If so, what should I do?

    Yes it's a big deal.

    Have it removed and get a new one pressed on.

    Maybe I'm off on my terminology, but I didn't think the fork crown race had an "inside". It's a bearing race that's pressed to the crown of the fork, and the only exposed surface is the top where the bearings will roll.

    If the frame and fork were separated (as they should be) when it was powdercoated, and the crown race wasn't masked off, my initial concern would be to also check the condition of the pressed cups (which were probably left in during the powdercoating) to find out if the bearing contact surfaces of those got ruined as well.

    the frame and fork were separated during the process. I took the headset cups off before i gave it to them. They wrapped the whole steer tube and didn't wrap the crown.

    Automotive gasket remover will remove powder-coat. Just spray some on a q-tip and apply it to the part that needs to be bare. It is corrosive as hell (duh) so be careful, only have two beers before applying it....

    doh, misread OP. I'd just clean up the bearing contact surface real nice-like.

    I think it'd be pretty ridiculous to actually know enough to check and worry about that, but then use some gnarly 320 on a polished bearing surface (which it seemed like he knew it was.)
