Has anyone ever taken theirs apart? I get really boored in the colder times. I decided to make sure everything was clean isside the vest system. I did find a bit of sand/dirt. No big deal. Most of all I was blown away by how overengineered this simple piece is. There is a steel ball bearing sort of thing inside that is along for the ride. With piecees like this on our bikes, no wonder the prices keep going up. I wonder what other pieces are there that could be made more simple???
