Premium mini pump with impressive features. Very smooth operation, precise guidance, and stylish design. High-quality, CNC-machined aluminum construction with low weight. The rigid, extra-large piston ensures stability and long durability. The compact design offers over 30% more piston stroke compared to conventional hand pumps. 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 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.
