SS - The seat tube on my SL-1 also broke after about a month of riding/racing on it. It cracked right beneath the slit where the seatpost clamp sits. Kind of an odd crack and I don't believe it was a result of over torquing as I used a torque wrench and an aftermarket Campy seatpost clamp. Still waiting to hear back from the Fuji warranty guy, and am curious to see how they sort out your situation.
