For a normal 1.125" steerer.
Are there any reasnobly priced and sensible weight ones out there? Upping the fork travel and need a new headset anyway, might run a S3 upper headset to mitigate some of the weight as I don't want to be adding yet another 100g to the bike unnececeraly (done a lot of that recently with chain devices, tyres, wheels, brakes, saddle, seatposts etc and there'll be another 500g in the new forks!).
So basicly, any alloy ones with a sealed bearing out there? Or is it a Chris king Steelset or nothing? Considdered a crank bros but even if its warrentied there'd be nothig left of the headtube if it needed basing out repeatedly over the next 5 years!
Cane Creek do one.
Why do you need one? Not for a Nicolai is it?
Acros do one that is 125g:

Specialized pitch, fitting some lyrics. Not a need, just a nice to have, and it'd be an ironic PITA if I mullered the headtube having thought about it beforehand!
I have nukeproof one in the tandem. I actually had to get the cups turned down as the insertion was longer than the recess in the headstock. Nicely sealed angular contact cartidge bearings
Its alloy so not too heavy
Which nukeproof one, I can only find the 34ssee which isnt deep cups?
Acros from Balfa is light. Bearings are stainless... and from experience can be replaced if needed. I had an early one many years ago which was not stainless and when the bearings rusted Jamie at Balfa sorted me out.

I wouldn't bother, Specialized headtubes are very strong - never heard of one going.
Neither have I, but I've tought aout it now, so it's a gaurente!I wouldn't bother, Specialized headtubes are very strong - never heard of one going.
tinas - the exact one I had seems not to be done anymore. Must be sommat in the range tho
Think I'll go with the blackspire shore and see who heavy it is when it arrives, if it's overly chunky then I'll bin the top cup and use an S3 top cup.
it will be heavy for a headset, but still probably only 150g compared to 100g for a normal one
[b]do not fit one to a frame with an internally butted headtube if you ever want to take it out[/b]
i got a 3rd hand CKsteelset cheap many years ago and fitted it to a gary fisher lightweight frame, its now VERY well seated and won't budge regardless of hammer size!
Specialized headtubes are very strong - never heard of one going.
I've fitted headsets on around half a dozen Specialized frames and they all, if my memory serves me, had machined recesses on at least the lower portion of the headtube. I don't know that a deep-cup headset would fit without modification.
every frame I have ever seen has a machined recess for the headset in the head tube. My tandem one was only 14 mm deep and the headset I got 20 mm insert so I had to get it turned down.
I've got a used Acros ah-07 that I may part with. It's only a few months old & has slight marks from removal. Even I you're not bothered about mine, be wary of the blackspire headset, it has a fairly poor reputation. There's a lot about it online.
