Specialized Air Tool Switch Sport Pump Every rider has a horror story about a time when they flatted in the middle of nowhere. Having a proper tube or tubeless plug kit will only get you so far if you don't have a pump. Enter the Specialized Air Tool Switch Sport pump. With its included water bottle boss mount you can be sure you'll never leave it behind. The Switch Hitter works with both Shrader and Presta valves without the need for disassembly. The plunger design locks to the body chamber with a quick twist preventing the pump from extending while mounted to your frame. If you're looking for a compact pump that can handle a variety of cycling disciplines then look no further.
