The aero-shaped barrel and wide steel base provide stability when pumping and the 3" top mounted gauge is easy to read up to 200 psi (14 bar). The large padded handle provides comfort while the extra-long and tangle-free hose can even reach wheels on bikes mounted in a stand. The SmartHead(R) DX3 with lower profile air release button automatically adjusts to fit either Presta or Schrader valves and makes getting the right pressure a simple task.
