Lezyne HV Drive Pump

This is a good portable pump to carry. We tested the medium which actually measures 7 3/4" - it fit into a short(ish) bag. And more importantly, the screw-in pump end for either Presta or Schrader valves is easy to use - especially on the road, in real world conditions.
 
Barrel and shaft made of lathe turned luminum: end caps and handle made of composite matrix
Inflates tires with 30% fewer strokes than traditional hand pumps due to the HV (High Volume) design
Equiped with the ABS (Air Bleed Equipped) Flex hose (Presta/Schrader) and a composite matrix mounting bracket
Max: 90psi
Weight: 94g (small / 166mm), 109g (medium / 214mm)
 
Note: We have the medium in stock which actually measures 190mm long (just under 8").
