CNC-milled hand pump made of aluminium. Handle, cylinder and piston are made of aluminium, end caps of composite matrix. 30% more piston stroke compared to conventional pumps. The overlapping handle and cylinder flow into the compact design. The Lezyne ABS (Air Bleed System) flexible hose system works best, protects the valves and is easy to store in the pump housing. The ABS (Air Bleed System) flexible hose is simply screwed onto Presta or Schrader valves. By pressing the ABS button, the air pressure can be released from the pump hose, making it easier to remove the flip-thread chuck from the valve and no air is lost. When using Schrader valves, the tyre pressure can be adjusted by pressing the ABS button.
