A few weeks from now my road bike will be shipped from South Korea to China, and I'm nervous that it will be damaged in transit. I'm curious to know if anybody has any anecdotes that tell how the bike was damaged from shipping by air which would help me with tips for packing my bike? 

I bought a hard case.
