Specialized Air Tool Switch Sport Pump A mini pump is an essential part of any cyclists' riding gear, and with the Specialized Air Tool Switch Sport Pump you have an easy-to-use, durable and affordable bike pump that will get you out of any deflating situations quickly. The SwitchHitter head automatically adjusts for Schrader or Presta valve inner tubes, so both your road and mountain bike tubes are accounted for. With a max pressure of 120 psi, you'll be back on the road or trail in no time. The durable plastic barrel couples with an aluminium shaft to maximise pumping power by reducing flex and improving efficiency. Also included is a water bottle boss mount, allowing you to easily attach the pump to your frame via its bottle cage mounts.
