Seriously, what is wrong with an integrated headset. The headset on my capo hasn't given me any grief yet and I don't expect it to. The pista concept has one and people are falling over themselves to get one. Has anyone here actually had a spectacular integrated headset failure? I can only really see that happening while doing tarck tricks and even then, you'd have to be a lil dense to be doing tricks that could blow up your headset on a carbon fork anyway.

As far as longevity, I don't think too many of us will keep our bicycles long enough for an integrated to "destroy" a frame anyway. I know I'll be hit with upgraditis long before my headset explodes through my headtube!
