Rims too deep for your valves? These inline valve extenders work with tubular tires or tubes with removable Presta valve cores. Use the included valve tool to remove the valve core, then thread the extender right on to the valve base before re-installing the valve core in the end of the extender. The built-in rubber o-ring seals everything tight, but teflon or plumber's tape can be used for an even tighter seal. The valve extenders add 50mm or 70mm to the length of the existing Presta valve.
