I noticed a weird noise when pedalling. I had my road bike with me when traveling (airplane), and I just came back from a trip. I only had to take the wheels off when packing it. Once I assembled the wheels back on, and gave it a try, I noticed this noise.

What could it be? I tried lubricating the chain but it made no difference.
