The crown race is the part of the headset that gets installed on your fork's crown and seats the lower bearing - which you obviously didn't install correctly. Assuming you don't have the proper tools to do so, you need to take your bike to a shop before you **** something up.
Your headset came with installation instructions. You may want to at least look at them.

That's pretty vague. What's your price range?

This is one of those deals that a shop will charge you a fraction of the cost of the tools to do it yourself and trying to fart around will ruin a part that costs more than the shop would charge. If you promise to keep quiet while they work, they might let you watch.

Seriously. My shop charges a whopping $5 to install a crown race - $10 if it's being moved from one fork to another.

When you're building up a wheel with an eyeletted rim, do you grease or oil the nipple where it meets the eyelet? Is it necessary when using brass nipples?

Dude, how in the **** did you build my wheel set without taking the finish off those nipples?
I had to do a repair today on the back and it looks like I put them through a ****ing garbage disposal.

Hey Scrod,
Having issues with my Nitto 626 seatpost. Basically, it won't keep the saddle locked down.
I had a B-17 in there and it was fine. I adjusted the saddle angle once and it wouldn't keep it. Now I just changed the saddle out to a Brooks colt and it won't keep it locked either. I broke it all down a few times and every component looks fine.
Any idea what the problem might be?

Scrod, I want to change my rear hub, spoke calculator says the new hub needs 1.2mm less spoke than the old hub...Too much a difference? its on a B43 BTW which may mean it won't matter

The finish comes off Sapim nipples if you look them the wrong way. I usually grease the outside of them while building and use a spoke wrench the next size up to help prevent it a little.

So when any seatpost doesn't keep the saddle in place, what's the usual culprit? I've read about roughening up certain contact points so they grip better.

It's usually either due undertightening or stripped threads preventing you to tighten it properly. Roughing up the contact points wouldn't really do much, if anything at all.

I can't tell from the picture---is that a one bolt adjustment**********??? I have a Look Ergopost and have to tighten the snot out of the single bolt or it will slip.

Yeah, Nitto 626 is single bolt. Man, if I had slippage issues with a double bolt, I'd throw that thing through a wall.
Thanks Scrod, I'll try it again and crank it with a slightly larger wrench. If that doesn't work, I'll look at replacing the bolt, although the bolt and threads look fine.

It may not be the bolt, but what the bolt threads into.
