Are integrated campy 45/45 headset bearings really that touchy

So, I have had this bmx up and running for a few weeks now. I kept the tires on the ground for the first week, to let thing settle in a bit and I'm still adjusting to it as well. The next week I started lightly hitting curbs, to shake anything loose and re-tighten stuff. The week after that I started hitting things a little harder and jumping more frequently, I've probably pulled six feet of air on this thing at most.

My headset started making that creaking sound that I have read so much about. Everything was and still is tight, when I took apart my front end to check and clean everything the top bearing was fine. And bottom bearing seemed to me like it was starting to ovalize on me, it was hitting on two sides when I removed it out of the headtube. When I popped the bearing in new, it didn't seem to rub on the headtube as much as it did on on removal and re-installation.

It's a sunday headset if that makes any difference. Is that just how these things are? Shits tight, like nearly overtightened. It's dry, head tubes clean and free of debris, bearings are smooth as butter and it started creaking on me again the day after i cleaned it. There sealed bearings that just pop into place, does the headtube need grease?

is the frame old? could be ovalized headtube


Also make sure it's assembled properly and that the top of the steerer tube is at least a few mms below the top of the stem. You don't watch it flush with the stem otherwise it won't tighten properly, you want it slightly below it no more than probably 10mm, no less than 3-4mm.


The bearings shouldn't matter, they're all the same besides a few minor things that shouldn't be making it creak anyway.

It's all new. Headsets assembled correctly, stems higher then the forks, the only thing I can think of is the headset spacer right below the dustcap, maybe thats causing it to creak?

The super thin spacer you mean?

You sometimes need that because otherwise the dust cover can rub the top of the headtube. You can try taking it off and see if it fixes anything but I doubt it.


Try adding some grease in the bearing seats and see if that helps. Since it's all new it's likely bone dry and needs some grease in there.

I always put some grease in the cups/frame where the bearings rest to avoid some creak. Also check and make sure your bars are snug, and the stem too.

Does it creak when riding around, or when the bars turn only? If it is when turning the bars, there is likely a piece of rubber that is sliding on something. I use Bike Aid for that(Thin moly lube) or grease.

It makes the creak sound when my bars turn. Bars are tight. stems tight. I have an alienation iron madien stem, it's rock solid and amazing.

I'm assuming the rubber your reffering to is the side cover things on the sealed bearings?

That or any o-rings in there. Also see if the top cap is touching the top of the head tube anywhere. Just a tiny dab of grease could clear up the creak.

Any good bike shop shpuld have the tools you need to reface your headset seats. Did with a frame of mine years ago at a roadbike shop when i used calipers to find out my seats were distorted during welding.
