I am on my way to a new bike SOON! I'm leaning on either a Trek 5200 or the Madone 5.2. However, my brother-in-law, who is an avid rider and works for a bike shop is trying to steer me away from carbon. He says that if you wreck or even if the bike gets knocked over, this could potentially render the thing useless. Also, he says that the carbon is of lesser quality now because it's all coming from China, then being put together here. Is any of this true, or should I thank him for his advice and go my own way? Any additional words of advice in either direction would be much appreciated. Either support his claims, or give me some ammunition against him! Thanks.
