Most of my tools are contained within the Topeak Survival GearBox. It's got a couple of screwdrivers and allen wrenches, a patch kit, a chain breaker, and some mini crescent wrenches.
I also carry 2 steel tire levers, a spare tube, a Park GP2 self-adhesive patch kit, Topeak Road Morph-G pump, some red cable ties (because the red ones are lucky) and some duct tape.
The Chilly Hilly is a fun ride and if you don't have everything you need, there's plenty of people on the course and I'm sure someone would stop to help you out. If you see a 6' 6", 250# guy who looks like Sasquatch riding a black Cross Check, say "hi" to me.
