BikeSmart's dual action PortaFlate inflates tires on both the push and pull strokes, getting you back on the road or trail in less time than you thought possible from a mini pump. The smart head automatically adjusts to fit Presta or Schrader valves, and it comes with mounting hardware, including long screws for mounting beneath your bottle cage. Plus, its durable aluminum construction will stand up to the rigors of riding for years to come.
