Quality Tube 700 Presta Valve 23-25 32mm
The Q-Tubes Road Bike Tube isn't expensive but it is pretty necessary, so it's always a good idea to have two or three around, just in case. Keep 'em wherever, and rest assured that their durable design and reliable Presta valve will lock in the air, at least until you run over another broken bottle.
