I test rode a Tricross back when they first came out and absolutely hated it. There was something going on with the fork. When you braked hard the fork chattered badly. Did some internet research and found that it was a design flaw of the fork and that it was a widespread problem.
I liked the rest of the bike, just hated the fork. If they fixed the fork (they may have - haven't ridden one since then), I'd recommend it.
