My bag contains: wallet for bc licence / accreditation card, race number, cleat covers, 15mm wrench, puncture stuff, multi-tool, arm-warmers, scrunch-up raincoat, lights, snacks, bug spray.
I can never be bothered to change gears so I don't usually carry chainrings or cogs, although if my bike lived at the track I might do more often.
Sometimes people carry a spare cockpit for pursuits, etc.
