Topeak TubiHead Pump Upgrade Kit (w/Hose)

Allows a standard floor pump to deliver massive amounts of air volume by temporarily removing the presta valve core Can also be used as a regular volume pump without having to remove the valve core Because the pump head removes the core internally, no pressure is lost or sealant spilled Integrated pressure release button for releasing the pump head from the valve stem Clear body allows you to see the valve core being removed and reinstalled Makes seating tubeless and other stubborn beads more easy
