The reversible Presta/Schrader ABS Flex Hose combines the threaded security of the Lezyne Flex Hose with the Air Bleed System (ABS).

The hose threads securely onto valve heads for an air-tight seal and prevents valve damage during inflation.
When using Presta valves ABS allows users to release the air pressure in the pump hose making it easy to remove it from the valve and eliminating the chance of unthreading removable Presta valve cores after inflation.
When using Schrader valves ABS allows users to adjust tire pressure.
