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 valve body without pulling or twisting. To release, all you need to do is slide the Pump head off the valve by pressing the large red button as you pull away from the valve.
The Standard Schrader thread connection makes the Pro Presta Head the perfect upgrade for your current Pump. The head is built to handle the abuse of pro workshops, with a durable steel body.
