I just bought my first frame with an integrated headset. I would have preferred a traditional head tube, but the frame deal was just too good a deal to pass up. So please excuse me for the following stupid questions, but it would be great if someone with more experience than me can answer the following questions.....
The frame comes with a cane creek integrated headset.
1. Are the bearing "cups" (the ones that actually go inside the head tube) of an integrated headset supposed to be an interference fit (like traditional cups) or a loose fit? They are a loose fit in my new frame, should I artificially "knurl" the ID of my head tube with a punch??
2. The "seat of the crown" of the carbon fork is way bigger than the crown race. How is the crown race supposed to be removed/replaced? I mean there is no way to use a traditional crown race remover with such a fork. Does one just use a screwdriver?

Cane Creek bearings drop into the frame; they have no cups in the traditional sense.

Loose fit; they just fall in (and fall out when disassembled).

No, loose is okay. Play can be taken up with the matching conical fit between the bearing and frame.

I agree that's a RPITA. I think Park makes a big fancy puller that slips between fork and race.

Dear Dianne,
As usual, you're right. Here's Park's universal crown race puller:

You may be confusing integrated with internal. The difference is that integrated seats the bearings between the frame and the fork:
Which one do you have? It may help to let us know what brand of frame and what year it is.

Sometimes the standards a little different. Your LBS should have an assortment of crown races that should fit in case the one you have doesn't. ISO and JIS standards are one example.

Well, I admit my use of the term "cup" probably confused a lot of people here. But the frame specs say "integrated headset," and the head tube has some conical protrusions along the inside diameter. Plus Diane understood me. 🙂 Thanks for the links Phil.
I just about fell out of my chair when I mocked up the headset after receiving the frame today. I just could not believe the integrated HS had no interference fit with the exception of the crown base plate, and the bearings would just fall out. That was something that completely shocked me, not ever having seen an integrated HS up close and personal. I almost convinced myself that the frame (head tube) MUST have been defective.
Live and learn I suppose. I don't expect the frame to last long; I basically got a whole frameset (including carbon fork + HS) for less than the price of a carbon fork alone. Now I'm contemplating whether to risk my life, void the warranty and file off the lawyer lips on the fork. 🙂 It's not clear where metal ends and carbon starts near the dropouts......

Make sure you need a fork crwon race..some fork/HS models don't need a FCR...

Something from Chucksbikes.com, perhaps? Or a Scattante from Performance? Or??

Tread carefully, you really do not want to "nick" the CFRP with a file.

The last integrated headset I took apart had a crown race with a split in it. It was the easiest thing in the world to take off, because it wasn't a press fit at all. Yes, it was meant to be that way. The split wasn't a problem because the bearing contact surfaces are inside the sealed cartridge bearing.
