Internal headset standards
 

I'm trying to figure out what type of internal headset will work with my frame. The store I bought it from said it was the "Cane Creek kind", which I'm assuming is the Zerostack. Is there a table anywhere that lists what headset is compatable with what measurements (ID, depth, etc)?

The only dimension on Cane Creek I can find is a headtube ID of 44mm for the cups to be pressed into. Ritchey lists their ID as 44mm as well, but also says the insertion depth is 9mm. Is the depth not that important? Is this the same standard?

Those are the only dimensions I've found. I haven't searched for Campagnolo's yet since I've heard several times that they user a different standard. But if anyone knows that and wants to share that'd be good in case anyone else is having the same problem w/ a different headset. (EDIT: Ritchey site says their internal headset is compatable with Campagnolo headtubes - 44mm/9mm)

[rant]Frustrating as no place seems to clearly spell out what the differences are between Campagnolo and Cane Creek. And online retailers calling internal headsets integrated.[/rant]

Thanks.

Thanks for the link. It mentions the industry standard of 44mm ID. The same measurement that Campagnolo/Ritchey/FSA have listed.

Is the ID the only factor to consider or is there something else that'll bite me in the ass if I try to install a Campagnolo internal headset into a headtube designed for a Cane Creek?

IIRC, the bearing seat angle differs between Cane creek and Campy. Cane Creek is 45 degrees and Campy is 36 degrees (?) They are not interchangable.

When they first went to integrated (actually zero-stack) headsets Litespeed tried to make their head tubes compatible with both Cane Creek and Campy cups and wound up fitting neither.

So it's an issue of the internal cups fitting into the headtube? Is the bearing seat angle the angle of contact between the bearing and the cup? If so, why would it affect the cup's installation into the headtube? Sorry for being so dense, but I'm trying ot get my head wrapped around this.

AFAIK, the recess in the headtube has to match the bearing seat angle since the pressed-in cup shares that angle. Litespeed tried to machine in a compromise angle and wound up with a huge problem of squeeks and other noises as neither maker's cup sat properly in the recess. They replaced a lot of headtubes under warranty after they finally settled on the Cane Creek specs.

If you disclose the make/model/year of your frame, perhaps someone will know what type of headset you need.

Maybe a simple email to Cane Creek would get you a list of their recommended headsets for your frame.

Or, maybe the LBS where you bought the frame would sell you an appropriate headset? For a small fee, they might even install it for you.
