It was a kind of a rhetorical question, but I don’t agree.
I’ve had a Hope headset fail in under a year – an old 1 1/8 one to be fair, but it was still poor.
Especially with integrated headsets it’s all about the bearings these days, as the amount of metal in them is fairly minimal. AFAIK Hope don’t make there own bearings.
These ZS ones have a bit more machining in them compared to some fully integrated ones that are literally bearings, a race, and a top cap.
However, if you actually grease your bearings a couple of times a season, and don’t aim a jet wash at it, then they should last ages,
If I was the OP, I’d look at replacing the bearings. If not then the Brand X will just as good as the Hope (IMHO anyway). £70 for the Hope is just daft money!
