Crank Brothers Pumps
Power pumps are available in different materials and lengths, and with or without a gauge. All feature several pieces of Crank Brothers ingenuity. First, a double sided head for instant schrader/presta valve compatibility, which rotates to lock the valve, Second, a double acting piston system uses both the handle and the shaft to move air, and a pressure switch adjusts the pump to move less air, but at a higher pressure.
