Lezyne HP Drive S

CNC-machined hand pump made of aluminum. The handle, cylinder, and piston are made of aluminum, while the end caps are made of composite matrix. It features 30% more piston stroke compared to conventional pumps. The overlapping handle and cylinder contribute to the compact design. The Lezyne ABS (Air Bleed System) flex hose system works excellently, protects the valves, and can be easily stored in the pump housing.

The ABS (Air Bleed System) flex hose simply screws onto Presta or Schrader valves. By pressing the ABS button, air pressure can be released from the pump hose, making it easier to remove the flip-thread chuck from the valve without losing any air. When using Schrader valves, tire pressure can be adjusted by pressing the ABS button.
