You over tightened the seat tube clamp. When you do the bolt pushes in to the bottom of the top tube near the joint with the seat tube. Im guessing there is a little bump on that diagonal piece at the joint right? How safe it is depends on how much the bolt caused a protrusion. Ive known another person who did the same thing and had a small pimple like bump, but it didnt break through the carbon. That bike is and continues to be fine. Its a redundant area thats really only there to accommodate the seat post clamp. That being said, it all depends how hard you pushed the bolt through... realistically you are fine though. Lesson: Go buy a torque wrench. Torque specs are on there for a reason.
Good info, but I promise my cracked (under the seatpost binder) frame has never been over 5nm because a Ritchey torque key is the only thing that fits in there properly.
Neither of my torque wrenches have a small enough head to go after the bolt straight on and I don't trust the ball head bits for that work. That being said, I didn't figure it would affect anything and have been riding it (with a smaller bolt) for the last year. After the steerer cracked at a race last weekend, I'm thinking I'm done with the 2012 Time Machine. I hope all of you have much better luck.
