The other is a safety flag. Don't have a picture of this yet but it's not really necessary. I feel safer with that thing waving above me. I also decided just to remove my chain idler altogether. It was noisy and annoying, and I don't think my chain really needed it. The bike still rides perfectly without the idler, the chain's high enough off the ground, and it's soooo quiet now! Love it.
