The problem here is that unless you cut your frame in half, as he did, you wouldn't know what's inside your frame, regardless of the material it's made of. Even buying a new steel bike doesn't guarantee that the inside of the tubing hasn't already started to corrode in certain places. It could also be the worker that built the frame that didn't take the time to do it correctly, whereas other workers would do a better job. Personally, I think that the quality control of the factory they contracted with was not up to par or this would certainly not have happened. Let's hope Bianchi is using a different company to build their frames.
