I'm the proud owner of a 2011 Salsa Casseroll, my first bike in many years. I have not yet put the standard front rack on the bike, but I'm thinking I'd like to get a small bag to put things like a camera, snack, etc., to mount on the rack. All the ones I've seen that are made for such a rack are $$$ randonneuring bags, made of waxed cotton and leather. While these are beautiful bags, I want something more utilitarian, and cheaper! Any suggestions?
