It’s just a headset really – as long as it’s got decent quality bearings in then the make isn’t too much of an issue.
Thinking about recent headsets:
Hope – got one half price for £40 with a frame but only 4 rides in so far
Bird (I think these are made for them by superstar) – had 18 months on one and both bearings were still perfect. Got ridden through all sorts of slop etc.
Cane Creek 40 – had one of these for 3 years ish in a bike. The bottom bearing was just beginning to get a bit gritty at that point.
Brand X – not well sealed at all. I don’t think the crown race had a rubber but to shield the bearing and after less then a year the lower bearing wasn’t wildly happy with life.
Not used a Nukeproof one.
