If you've broken a pump, or worse, a valve core, while frantically trying to fill your tube on the side of the road, you'll appreciate Lezyne's Flex Hose design found on the Road Drive Pump. The Flex Hose allows you to attach the holes to the valve, then pump air into the tube without worrying about being at just the right angle. On top of that, the Road Drive is capable of returning your tires to 160psi, so you won't be handicapped by a soft tire for the rest of your ride.
