Re:

Thanks for the tip. Are Tange Levin and DA both threadLESS, ahead or whatever though?

Hi all
This may be the one. I finally found a description of a decent looking sealed headset:

M:part Elite 1" Threadless Headset
This top of the range headset comes with a 3 year manufacturing warranty
Precision CNC alloy cups made from aircraft grade aluminium
Quad sealed precision angular contact bearings coupled with double sealed bearing housing, keeps the British climate at bay
Utilises flush seal technology to further protect the longevity of the bearings
Fully replaceable bearings and full spares back up available
Expanding collar design means once you tighten the headset, it stays tightened
Low stack height - 27mm
Alloy top cap and star-fangled nut included
Weighing in at only 92g (based on a 1 1/8" threadless headset with steel crown)
Designed and tested in the UK for extreme British riding conditions
Comes with JIS standard crown race only.

Re:

There is an offer at Tredz on 1" ECT headsets and these would appear to be JIS if 22.2/30/27 means what I think it means - and they are very reasonably priced - the better one having a water seal.

Re:

I now have an ETC silver headset - just what I wanted. Its the correct dimensions - but a very tight fit, looking at it. I'm a bit worried that I may not be able to replace the lower bearing in future though because its a caged needle roller device. The upper seems to be regular caged balls.
