Park Tool MT-40 Multi Tool
Best reliable multi tool for on the go bicycle repairs.
This is the ultimate roadside insurance policy for cyclists who prefer to carry less. By packing a chain breaker and CO2 inflator into a single, forged aluminum frame, it eliminates the need for a bulky repair kit, though the compact size means it lacks the leverage of full-sized shop tools.
