Prestacycle's new pro Presta head offers a Patented auto-lock mechanism. As you slide the head onto the Presta valve, the mechanism grabs onto the Presta pin without pulling or twisting. A seal is made on the Presta valve WITHOUT clamping the valve. Easy-grip sides make it simple to press the red button on the top of the head which provides full release of the connection without pulling on the valve or the core. Instant no-loss disconnect insures tire pressure is exactly what you put in there
