I have just bought a new frame which requires a fsa ce integrated headset.

My question is will any others fit? are all integrated headsets the same?

Bar a tiny difference in stack heights, all integrated are the same, sure it's not SEMI-integrated though?

Semi integrated has a mating OD of 44mm and is common on MTBs, integrated started with Campag on roadie stuff, migrated to BMX, is pretty rare on MTBs, mating OD is about 40mm from memory.

Possibly, alternatively what bike and is there a tech spec, or can you measure the diameter of the hole?

All integrated headsets are NOT the same.

For starters, there're two different standards: Cane Creek (41.0mm OD, 36/45°, blue seals) and Campy (41.8mm OD, 45/45°, brown seals).

Yes but the CC is known as IS2 for a reason.......

Cane creek is considered regular I.S.
Campy is often called "campy-fit". Not very creative, but to the point.
The o.d. is the easiest to check, as mentioned, cc=41.0mm, campy=41.8.
Cane creek made both kinds, now just does I.S.
An I.S. bearing will fit in a Campy frame (needs some spacing to clear the top cover), a campy bearing will not fit in an I.S. frame. Even so, i avoid putting an i.s. bearing into a campy frame.

I also need a new headset for my 2008 cervelo r3. Will a regular I.S. 41.0mm fit?

I would measure myself but dunno what to measure :noidea:

Measure the bore diameter the bearing sits into in the frame.

Did you buy an On-One frame? I had the same headset spec'd on my Whippet frame.

I used Cane Creek's headset finder to find their equivalent, because I won't run anything FSA if I can help it.
