I carry just the ball-end hex L-wrenches (extracted from an inexpensive Harbor Freight set) needed on that particular bike, plus my chain tool and a couple of master links, wrapped in a rag which keeps them quiet plus you can wipe your hands with it. The combination weighs less and performs better than a multi-tool. Try installing a bottle cage with a multi-tool vs a ball-end L-wrench and you will readily see the difference.
