Hey, I have an idea,
to use sealed ACB bearings to do this.
I am going to get some custom cups turned out of stainless-
that fit these bearings:-

The cups will go on the outside of the headtube.
Thanks for original idea!

Just letting everyone know (as cool as this original thread is) is that AHeadSet (Cane Creek) has modified their 1" and 1 1/8" headsets so that they all use interchangeable parts.  They also now sell a conversion headset but it's hard to find.  Or you can buy two of their relatively cheap headsets ($24 MSRP) one in 1" and 1 1/8" and interchange to get your 1 1/8" steerer into an old 1" frame. 

Pretty neat.  Here is the link to the diagram of parts.  Some of the supply houses carry all of their individual parts but it's probably easiest to just buy two in my opinion:

And here is the link to their configuration page that shows the adapter head set.  It makes a lot of sense to me..  :)

Nice man ty! I imagine I will prolly do this.
I still like my idea of putting the cups outside the ht,
coz then i can use sealed bearings.
The problem is every set of forks needs to have the step in the steerer turned off,
unless I can find acb bearings with 1 3/16 inner race.

I just ordered one of the Cane creek 1 1/8" and two 1" cups for $33 including shipping.


Fingers crossed. :beer:

How'd this go Old Yeller?
Thinking I will try and get 1 1/8 Kore forks on my Morales.

Complete failure on the cane creek.  The cups were the small ten speed size and the cups were too big to go through a gyro.


I ended up having a set of heavy duty cups machined to fit a 1" headtube.

Thanks for the info.
hmm-not sure what to do,
but it seems it will involve some machining.
My local guys just got a lathe-so, cool
Really want these forks on there,
so it will be loose ball at worst.
edit- so I think now I will machine the races out to 1 1/8,
and use 1"cups. Looking at the parts I think it will work.
Need some really tough races if I can find them.

hey, thank you very much, just chucked a set of threadless forks and a stem to get it working, FLAWLESS!!
used the cups that where original on the frame, top + bottom crown from the forks, and 3 lots of bearings from these and another similer, just did a hop down a 4 set of stairs, not even a wobble!
now time to get some decent forks + stem and ill be away
thought I'd add, the bearings are loose, the frame is a Raleigh Ultra Burner MK2 and the forks and stem where off some junker BMX for 8 but with a mix match of headset parts, it is super cool (wish id done this soon instead of snapping my Quill stem _ )


big respect!

Heyas 8D,
nice to be back at this forum, just got inspired to get back into my builds and riding.
I have now got 1 1/8 forks on my (newly black :) ) Morales,
which has a 1" headtube.
I can take some pics soon if anyone wants to see.
So I found some cups with thin enough walls on the bit that jams into the frame,
to let the 1 1/8 Kore forks through.
I also found some bearings, which remain in cages, that fit these.
I had the 1" bottom race bored out and re-annealed to fit the forks.
The top race is also bored out of a 1" top nut.
So that's all. It spins killer,
but time will see if it has enough strength.
So I didn't modify the forks or frame,
which I am happy about.
I will post pics of my 4 bikes including this mod in the next couple of weeks in rides.
 Cheers, enjoy the rolling
