I opened a brand new Bontrager tube this afternoon. Before placing it in the tire I gave it two quick pumps only to have the air escape out of what looked like a snake bit flat. Is this common? I guess I could complain to LBS or Bontrager, but I'll probably just patch it(who knows if they would believe me that it was that way out of the box). Its just annoying to buy a new tube and find it is already punctured.
