Plastic found inside my frame
I was peering down the seat-tube of my carbon fiber raodbike frame while washing it today and noticed something I had not seen before in the two years I've owned the bike. There was some remnants of what looked like a clear plastic bag in there. I was able to fish it out and sure enough it looked like someone stuffed a plastic bag down the seat-tube. I have some theories as to what this might be but would like to hear other people's opinions. Could it be?:
[1] The leftovers of a bag of illegal drugs and my bike was a "carrier"?
[2] Someone's old sandwich wrapper from an assembler on their lunch break at the factory?
[3] The remnants of the bladder used during the molding process?
At anyrate, I was only able to get most of it out but not all. The next time I do a BB service, I'll probably be able to extract the rest.
