My Tricross would shake fairly seriously when using the front brake. The mechanic at my LBS said it has a bad fork and he would order me one under warranty. Well, they didn't have one. However, my boss is a life-long friend of the LBS owner, so the way it worked out is that I have a S-series fork and headset on the way . It won't match as I have a green tricross sport, but hey, can't argue with the upgrade.
