My "winter" bike is a Specialized Tricross; not a true cyclocross bike but more a cross-purpose bike. It's heavier than the roadie but it's comfortable, smooth, very stable especially on packed snow and mud, with great gearing and BB7 disc brakes and it takes mudguards and a rack. I don't use it very often but when I do, I remember why I like it so much. It accelerates slowly but once up to speed it bowls along very nicely and on a recent 70 mile ride I felt pretty comfortable.
Jumping from that onto the carbon roadie is quite a contrast!
